Energous and FCC Approval for Mid Range Device - What Does It Mean?

More Energous Updates - Now trickle charging, 10Q shows a 9 month runway, FCC Chair promotion

A few brief Energous updates. There was a new article from Rhodri Marsden covering the technology area, and it was reasonably skeptical. The most interesting part for me was this quote from the Energous CEO:

Steve Rizzone, chief executive of Energous, responds by alluding to the lifestyle change mentioned by Bladen of Chargifi. “Mobile distance charging will not, for the foreseeable future, have charging power comparable to a wall socket,” he says. “But if you are continually topping off your mobile devices, you do not need to enable the same amount of power because charging happens continuously.”

So main points from here are 1) an admission they will not hit the multi-Watt charging rates and 2) that they are moving their public position to the "trickle charge" model where you don't charge the phone up, just try to halt or slow down the rate of battery decline. That's a pretty significant admission from a $500m market cap company - that everything they built the company on won't be happening "for the foreseeable future". A rational market would have seen a major price decline for their shares but for WATT, nothing. It's another indication this company's value is irrational - though that's not to say there won't be a lot of ups and downs, and money to be made and lost, before it finally hits zero.

Taking a look at the trickle charging claim - the FCC Part 18 data shows that maximum charge rate for a phone is around 100 mW at 50 cm from the transmitter, down to 30 mW at 90 cm. Ignoring RF to DC conversion loss, if you held your phone at exactly 50 cm away, square on to the transmitter, and didn't move it, you would extend the battery life from about 10 hours to 12 hours. At 90 centimeters you may add around 30 minutes if you are lucky. Don't hold it with your hand at the back of the phone though, or at an angle, you'll lose charging. This is me being nice to them with the numbers, realistically it makes no noticeable difference at all. Alternatively you could plug it in or place on a Qi charge pad and get back to 100% in an hour or so.

10Q
On the finances front, the 10Q was out for Energous, and it's not looking pretty for them. They had about $45m in the bank as of the end of March this year, with about $13.5m in per-quarter run rate. If that holds, they're out of cash in January, and by their own admission there are no significant products or revenue in that timeframe. Let's see how they either cut their expenses or persuade people to buy a few more tens of millions of dollars "worth" of stock.

Ajit Pai - Again
Once again the Chairman of the FCC, Ajit Pai, promoted Energous using the official FCC account. A reminder to everyone, this is a disgusting abuse of a public position for the private gain of his personal friends, and that's what we know about.
I took a little time to browse through Ajit Pai's Twitter feed and didn't see any other companies that got the benefit of his promotion.Did I miss any? I wonder what makes them so special to warrant this attention?

Theranos Updates - Loan defaults, layoffs, bankruptcy, and mega-rich families burning half a billion dollars.

Last month Theranos were back in the news, barely a few weeks after being admonished by the SEC for using lies and exaggeration to raise over $700 million from investors, this time for the CEO to announce that they were running out of cash and would likely have to close by the end of July. Approximately 100 employees will be let go in early June, leaving less than 25 who will most likely oversee a winding down of the company.

Theranos received a funding round last December, with a $100 million loan from Fortress Investment Group, which had many had been shocked to hear given the widespread knowledge of the company's difficulties. In my December article I pointed out things likely weren't as they seemed at first, and this was simply a predatory loan made in the knowledge that Theranos would in fact default, and that the lender would then take ownership of the company assets at firesale prices.

"So Fortress have arranged a deal where they don't have to put the full amount in up-front, but are still ahead of any other investor, get to own the only valuable part of the company if it goes wrong (the IP), and get discounted stock in the company if it, through some miracle, succeeds. With the right milestones and triggers, this could be a deal where Fortress win no matter what happens, and may actually come out better should Theranos fail. I wonder if Fortress have essentially arranged a deal to make sure that all the good parts are gone by the time everyone else reaches the bankruptcy auction.

Why would Theranos take such a deal? Well, because they have to choice - it's this or bankruptcy."

Well I'm feeling pretty smug right now, as that's exactly what looks to have happened. According to a letter Holmes wrote to shareholders (included at the bottom of this post, from Buzzfeed), despite having received $65 million from Fortress in December, they're about to miss a deadline for FDA approval on a device which will result in them not receiving the next tranche of $10 million. Most significantly though, should Theranos' bank balance drop below $3 million, they are in default of the terms of the Fortress loan, and the company predicts that will happen in July. According to Holmes:

Fortress would be entitled to control a foreclosure sale and/or monetization of the assets and to realize up to a three-times return on its investment (including, in addition to the amounts loaned by Fortress, the costs associated with Fortress’ monetization of the company’s assets). 

So Fortress get three times what they loaned, including whatever legal costs they have in extracting this money. A factor of three on the loan plus costs means they won't just get most of the company, they'll get all of it.

That $65 million gets Fortress around 1,175 patents (granted and applications) in the biotech space. They can sell them, licence them out, or use them to sue other successful biotech companies for payment. Given some large patent infringement payouts can result in 9 figure cheques, a single win like that will result in a great payday for Fortress.

It may not have even cost Fortress $65 million. I do wonder if they invested saying something like "This money cannot be used for legal expenses. It must be kept separate from all other cash and used only for salaries, facilities, and equipment." Knowing that Theranos had legal troubles they may have wanted to ensure the cash was not spent on that, and then set a stipulation that if the "other cash" account dropped below $3 million, the company essentially became theirs - regardless of how much of the investment was left. $65 million gone in basically 6 months, for a company of 125 people, is a monster burn rate. Even at a fully burdened cost of $400,000 per employee that's 'only' $25 million spent in 6 months. Facilities etc can be expensive, but not $40 million worth. In that case, Fortress would be owed $195 million (3*$65m), take the ~$40 million out the bank account that remains, then start picking the best $155 million of assets left (pretty much everything else) - making the cost of the whole company $25 million. Or maybe I'm just thinking too hard and Fortress didn't care, and just let them burn through it all with legal fees, thinking $65m was still a bargain.

Regardless, barring a miracle, Theranos are headed for default on their loan, and will end up being fully owned by Fortress. TheCEO amusingly asks for further investment to stave this off, but with the SEC judgement, and a skeleton staff, it's not going to happen. It will be interesting to see how Elizabeth Holmes does without the company to pay bills for her, such as for bodyguards, and with a likely criminal lawsuit coming. 

An Idiot and Their Money are Soon Parted
So who are the investors that Fortress jumped ahead of in their deal? Who put in the $700 million that got the company to this point? The Wall Street Journal recently published a list of major investors in Theranos, and it's now clear that the company was funded mostly by individual family investment vehicles, not traditional VC. Key investors were:
  • Walton Family $150 million
  • Rupert Murdoch $125 million
  • DeVos Family $100 million
  • Cox Family $100 million

So nearly half-a-billion dollars from four family investment groups, and they will probably see nothing back. (Murdoch already got out for a grand total of $4 million, a 97% loss). Pretty stunning, that. Now I'm going to bet on how much due diligence these companies did before investing, and I'm going with a number near zero. It was widely reported in March that when Theranos claimed revenues of over $100 million to investors, no audited accounts were provided, and investors failed to call a single supposed customer - and the actual revenue was $100,000. That's pretty basic due diligence that even the technically illiterate can understand. Think about the scrutiny you get when you go to the bank for a loan, and then realize that for $475 million no-one even picked up a phone and asked for a reference or a bank statement.

As for technical due diligence, they could have found a few well qualified scientists and executives in this area, and paid them a few thousand dollars each for technical and business evaluations. Total cost, less than 1% of the investment, but nope they couldn't do that either.

I've got no sympathy for them, they deserved to lose that money through their own carelessness - it's just frustrating that there are so many genuinely great companies out there that could work wonders on just a few million. That ~$500 million could have funded >100 hardware startups to a prototype/proof point, and made some genuinely useful advances - but the people that run those types of companies don't lie like Holmes, or exaggerate their technology, just to get a cheque signed (or, as in Holmes case, have well connected parents).

One bright side for Silicon Valley VCs, they can now say "See, wasn't us!", they really weren't the ones funding most of this decade's biggest fraud.

We'll definitely be hearing more about Theranos in the coming months, with the June layoffs, the July default, the inevitable bankruptcy and the possible criminal charges, but next up is John Carreyrou's book "Bad Blood". He's the WSJ journalist who broke the Theranos story, and his book is a history of the company, and will be out in two weeks (May 21st). My copy is on order, and looking forward to it. I fully expect a tale of insanity, greed, selfishness, and stupidity, and I'll review it as soon as I read it.







Holmes' Letter to Theranos Shareholders

April 10, 2018

Dear Theranos Stockholders,

We last wrote on December 22, 2017, shortly after closing a secured debt financing transaction with Fortress Investment Group. We said that the transaction provided us runway to continue work on the miniLab and to position the company for additional financing events—but acknowledged the narrow path forward.

Unfortunately, we are behind schedule on our first product milestone under the Fortress loan, and as a result will soon face a cash shortage. Below we detail our situation, apprise you of our options, and ask for your help as we continue to work to realize value for your investments. As we describe below, we are evaluating parallel paths, including potential investment terms that would provide a large stake in the company at what we believe to be a favorable price.
*****
The Fortress financing, which closed on December 11, 2017, provided Theranos with up to $100 million of liquidity, subject to product and operational milestones. The first funding tranche of $65 million gross was released at closing. The release of a second tranche of $10 million gross was contingent upon FDA approval or CE marking of the Zika assay for use on the miniLab. Achieving that milestone within the first half of 2018 was crucial to our business plan.

Development of the Zika assay has taken longer than anticipated. While the miniLab hardware and software have progressed steadily since we last wrote, we continue to face issues with the reliability of the Zika assay chemistry itself. As a result, timing for finalization of our FDA submission remains uncertain. We have raised with Fortress the possibility of releasing the second tranche of funding despite the lack of regulatory approval, but its willingness to do so is not assured and we understand that in any event it will likely depend on our securing additional commitments from our existing investors.

These developments leave the company in a difficult situation. Taking into account the substantial cost-cutting measures we are implementing today, including the reduction in force described below, our best current projections indicate that—absent further funding—our cash reserves will by the end of July fall below the $3 million minimum liquidity threshold required by the Fortress loan. Under the terms of our credit agreement with Fortress, our failure to maintain this minimum liquidity would constitute an event of default. Such an event of default, or other events of default that may accompany the company’s decreased liquidity, could precipitate an exercise of remedies by Fortress, including Fortress’ taking full control of our assets to satisfy the company’s obligations to Fortress. We expect that path would negatively impact the amounts, if any, available for distribution to our stockholders.

To avoid or delay a default under our credit agreement, we intend to take every step we can to preserve our remaining capital. Accordingly, today we provided notice, consistent with the WARN Act and other applicable law, to all but a small group of employees that their jobs will terminate in 60 days, on June 11, 2018. Difficult though that action is, we estimate that the associated cost savings will help conserve capital sufficient to fund our operations through approximately the end of July, without default under our credit agreement. After June 11, our remaining staff will consist primarily of financial, legal and administrative personnel alongside a core technical team, who will dedicate their efforts toward generating the maximum near-term return achievable for our stakeholders, likely through a sale of the company or its assets.

The most viable option that we have identified to forestall a near-term sale or a potential default under our credit agreement is further investment by one or more of you. In light of where we are, this is no easy ask. However, given your support of the company over the years, we wanted to provide this opportunity before we proceed too far down the current path.

Of course, even with new capital, the future of the company would remain highly uncertain. Nevertheless, additional investment may come with some meaningful benefits. A further investment could help protect your current one by providing the company time to continue developing the miniLab and/or to monetize its patent portfolio (subject to the terms and conditions of the Fortress loan). Further investment could also help us to avoid a sale for an uncertain amount—including a foreclosure sale following a liquidity-based default under the Fortress loan. Any such sale could significantly diminish the net realizable value of our assets. Moreover, in certain scenarios, Fortress would be entitled to control a foreclosure sale and/or monetization of the assets and to realize up to a three-times return on its investment (including, in addition to the amounts loaned by Fortress, the costs associated with Fortress’ monetization of the company’s assets). As a result, those scenarios would significantly reduce or eliminate any prospect of distributions to the company’s shareholders.

Our patent portfolio—which provided substantial support for the Fortress financing—contains more than 1,175 granted or pending patents worldwide. We believe our patents cover broad and important technologies, including: (i) the core technologies in the miniLab; (ii) technologies underlying point-of-care devices currently on the market and generating sizable revenue; and (iii) still-emerging technologies, such as an ingestible digital sensor that recently received regulatory approval for use in monitoring medication compliance. We also believe these patents have the potential not only to eventually protect the miniLab, should it receive FDA regulatory approvals, on the market, but also to support a licensing campaign that could generate significant additional revenues.

We have real progress to build on. Having rebuilt our quality system and implemented process-oriented safeguards for development and manufacturing, late last year we were granted a California Manufacturer’s License following an audit of our manufacturing facilities. Last month, representatives of a third-party notified body conducted an audit of our Quality System; we understand that the auditors will recommend issuance of the ISO 13485:2016 and MDSAP (Medical Device Single Audit Program) certification for the Theranos Quality System. We have also engaged a financial auditor, which expects to complete work on an audit of our 2017 financials by the end of June.

We recognize that the vision of distributed laboratory testing is what inspired many of you to invest, and we strongly believe that continuing our work toward that end could increase the near-term value of the company, and could provide the basis for building significant long-term value.

Although not yet set, the investment terms we are considering would provide a large stake in the company at a favorable price, in light of what we estimate is the intrinsic value of the company’s assets. We expect that new investment would take the form of a senior class of preferred stock, which would also feature substantial governance rights, allowing participating investors a significant role in steering the company forward.

Please note that if we offer new equity securities at a price per share less than the applicable conversion price of our existing series of preferred stock, the resulting anti-dilution adjustments could cause significant dilution to our existing stockholders. Such an offering would likely require the consent of the holders of a majority of our existing Series C-1B and Series C-2A Preferred Stock. The interests of these stockholders, who are senior to all other classes and series of stock with respect to payment upon a liquidation or deemed liquidation of the company, may differ from holders of other classes or series of our stock. Holders of Series C-1B and Series C-2A Preferred Stock should also be aware that their failure to participate in a financing having a purchase price of less than $5 per share would result in mandatory conversion of their shares into nonvoting Series C-1B* or Series C-2A* Preferred Stock.

Subject to our compliance with the preemptive rights of certain investors, we will offer this opportunity to all stockholders who are accredited investors within the meaning of Rule 501(a) under the Exchange Act of 1933, as amended. For any accredited investor who is interested in exploring it, we can provide a term sheet and are available to meet at any time. Irrespective of your future investment intent, we value your engagement as stockholders and welcome your questions and comments.

We request that you not share or discuss this letter with others, except your attorneys, accountants and other advisors bound by confidentiality obligations.

Energous Updates

A few updates on Energous happenings from the last week or so. First up, Chris Brown of Aristides Capital gave a presentation at a conference, "Kase Learning: The Art, Pain and Opportunity of Short Selling". It is the best presentation covering everything that is wrong about Energous I have seen, and neatly summarizes a bunch of what I have been saying in this blog, in a way a lay person can understand. According to their SeekingAlpha page, Aristides Capital manage about $83 million in investments. Here are the "Take Home Messages" from this 34 page work of art:

"The people who do publicity and media relations for Energous have done an utterly brilliant job selling vaporware. Congratulations, Ajit Pai and others.

The “advance” upon which Energous was founded, “the pocket of RF energy,” is a fabrication, a “dazzle them with BS” way of saying “constructive interference,” and doesn’t solve any issues. The reasons we don’t transmit large amounts of RF through the air for power—safety limitations, equipment cost and size, and poor efficiency—are the same as they have been for decades.

Energous is a fraud, one which is burning a lot of cash and will run out of money. The company has no chance of making a commercially successful product. We expect the stock will go to $0."

A link to the full presentation is here.

I added the bold above as I'm glad to see more people covering the what I said in my second post on this blog, over two years ago: "In theory, it can be done in limited cases, but in practice cost and efficiency issues will likely render it impractical." 

So many of the individual pages of this presentation cover topics I have often spent hundreds of words to try to get across in posts, so it's a lesson for me in how to be succinct and effective in this area. I won't repeat them all but a few memorable quotes:

Energous Corporation: a worthless equity hyped to $500 million

CEO who lies bigly and often

#FAKENEWS – false & unskeptical media coverage

If you tell the same big lie often enough, many people will believe it

and my personal favorite as an engineer:

Very small numbers add together to make other very small numbers

CNBC covered this and asked the company for a response:

"Energous did not immediately respond to a request for comment."

Download the presentation and read it for yourself, I'm not doing it justice here.

Speaking of "Unskeptical Media Coverage"
There was also a new wireless power article "When will your phone charge wirelessly in your pocket? We asked an expert" on Digital Trends. It focused on Energous and Ossia, with a brief mention of Powercast, so was aimed squarely at the RF at-distance wireless charging market. I was interested to see the analysis from independent experts and a balanced and reasonable piece on the practical issues surrounding this tech. You're going to be amazed by who the experts are:
  • Hatam Zeine - Founder and CTO of Ossia
  • Gordon Bell - VP Marketing of Energous
  • Mark Hopgood - Snr Director Marketing/Strategy at Dialog Semiconductor (Energous Partner/Investor)
aaaaaand that's it. Every single person interviewed has a financial incentive to promote this technology, they are completely biased. Not even a token attempt here to speak to a university professor of electrical engineering, or get a counter viewpoint. Spend a few minutes Googling Energous and you'll find plenty of stories out there on the less savory side of at least Energous. Of course I'm pretty biased since I'm one of those drawing attention to that. Is this a puff piece that's essentially PR for the companies, or is it actually an attempt to inform the reader? If the former, it achieved that goal splendidly, if it's the latter then it's a major fail.

Now I've been harsh on tech journalists covering this topic in the past, and while it's not the ass-kiss fest that David Pogue exemplifies, or the embarrassingly weak coverage from Tom's Guide where they got the wool pulled over their eyes on what they were showing,  this is still another company PR piece masquerading as tech journalism. I'm not sure the author even realizes he's being used by these companies to whitewash their PR and give it a veneer of authenticity.

I was about to take apart the rest of the article, but in the end realized it's just more of the same of what I've written on other journalists. Instead I'll just make this one point - whenever I talk to journalists about Energous, I'm either asked if I have a financial interest or conflict of interest. When I post online I always get someone replying that I'm just a short-seller looking to make money, or am upset I'm losing money shorting the stock despite my repeated statements that I have no position on the company - I even had someone who owns a wireless power company demand that I declare my financial interests because I was, unlike him, clearly biased. Why do I get more scrutiny about my motivations than someone who is doing it for the money? Only answer I can think of - when someone isn't doing something for money, it confuses people. The idea that you're doing it simply "because it's the right thing to do" is utterly alien and therefore suspicious.

Energous' Financials
It was also time for Energous' quarterly financial results, and once again there were no surprises here - it's still a ~$500m company with $25,000 in quarterly services revenue and no sales. With cash in the bank and the current burn rate, they have 9, at best 12, months of operation left before further fundraising is needed. All talk of product delivery and profitability was once again pushed out into the future, as seems to happen every time. By their own admission, they can't get to revenue before they run out of money, let alone to enough sales to break even. No mention of Myant dropping WattUp from their Skiin product, you'd think given the big deal they made of that product announcement a few months ago that it would be important for investors to be told about that. A transcript of the earnings call can be found here. Oh, and they're also awarding themselves millions of dollars in equity because they're doing such a fantastic job.

Energous FCC Approval Shows Weakness of WattUp Technology

More Energous news today with the announcement of another FCC approval, this time the "unlimited power" Part 18 approval for their Near-Field, contact only, system. You may remember this from May last year when it was approved under Part 18 at 5.8 GHz for 1 Watt transmitted output, but this time approved at 900 MHz at a staggering new 1 Watt transmitted output. Accounting for conversion efficiencies, that might be enough to charge your phone in 10 to 20 hours! Apparently this is momentous news and so WATT shares leapt 25% in after hours trading, because... well for no reason other than this is a volatile stock that trades on hope and greed, not an actual product or profits.

Why was this approval needed? Well, Energous had been advertising the WattUp family, that what charges with the Near-Field device will also work with their upcoming Mid- and Far-Field systems. Unfortunately, they learned in summer 2017 that the FCC would not allow the Mid-Field system to pass Part 18 at 5.8 GHz, and so they scrambled to change it and go with ~900 MHz, the only other frequency band realistically open to them. It got them the approval, for a pitiful amount of power (30 to 100 mW) at a small distance (0.5 to 0.9 meters) and a safety cutoff below 0.5 meters, but broke the promised compatibility with the contact version - the frequencies were just different. 

Now, this new approval allows them to market the compatibility, and it will be quite a campaign, I can just imagine it: 

"Charge your phone on a pad in around a day, and then charge at a distance in ten times as long! (Warning, charging only valid at 0.5 to 0.9 meters, safety cutoff closer than 0.5 meters)".


If you want to look at the data for yourself, look here, then search for Energous under the Applicant Name, and look up the product 2ADNG-NF230 at 918 MHz. You can see that transmitted power is limited to 29 dBm (basically, just under 1 Watt), and they likely have some antenna gain to pretend it's closer to 3 Watts. While there are two antenna to try and ensure the device charges at any angle, only one is active at any time.


Like the Mid-Field system approved at Christmas, the Specific Absorption Rate (SAR, a safety limit) seems to be what stops them, and is around 0.864 W/kg. While the limit is 1.6 W/kg, with safety margins it is hard to go much higher. Basically, this is as much power as they are ever going to put out. Further, unlike the Mid-Field, the CEO cannot pretend that the charge rate can be increased by altering the safety zone - there is none. This is as good as it gets. (Yes, Unlimited Power Part 18 does mean "around 1 Watt max").

For comparison, the Qi standard is around 5 Watts, with a high power version at 15 Watts - Qi is the resonant inductive method you're most likely to have seen, and that Apple has essentially chosen for AirPower. USB cables charge at anywhere from around 5 Watts to 100 Watts (though practically most today are around 10 Watts).

So at less than 1 Watt it's easy to see why Myant dropped Energous from their product. It would likely be ~10x slower than the cheaper, simpler cable they look to be providing instead. As a partner of Energous, Myant would have known this was coming, but still dropped it from the lineup. If "waiting for compatibility with long range charging" was the excuse, then that's gone, as both Near and Mid versions are at ~900 MHz now. Myant could put in the 900 MHz contact charging into their product now, and switch to the at-distance chargers later. If a key partner isn't taking advantage of this feature, IMO that's a major warning flag that something is rotten in the WattUp portfolio.

As with the Mid-Field FCC approval documents, this data shows how impractical the WattUp charging technology is, and how it can't be scaled up from here. This won't stop the Energous fans from claiming another victory, that the stock price boost is a sign of impending greatness, however it's just another well timed news dump of practical insignificance that will goose the stock for a few days. Just one of the occasional bounces you can expect to see on the way down and enabling some to make a profit from the volatility, not the value. I continue to admire Energous for their ability to boost the stock price and keep the game going longer. I wonder when we'll be seeing the next set of insider stock sales...

So is this overnight addition of $100 million to the market cap indicative of great things to come? I'll leave you with this, another reminder of what the Energous CEO said almost 2.5 years ago in the Q3 2015 earnings call:

"Here is a brief summary of the results of the amount of actual power delivered to a device at varying distances with a single WattUp transmitter. Power received at zero to five feet measured 5.55 watts compared to our targeted performance of 4 watts. Power received at five to 10 feet measured 3.74 watts compared to our targeted performance of 2 watts and power received at 10 to 15 feet measured 1.06 watts compared to our targeted performance of 1 watt."

They can barely do 1 Watt when in contact in Q2 2018. Still believing they'll deliver an actual product?

(My regular reminder, I have no financial position in Energous, long or short, or any other wireless power company)

Myant Responds to Questions Over Dropping Energous

Yesterday I wrote a post indicating that Myant, a "hi-tech clothing company", looked to have dropped Energous wireless charging from their upcoming Fitbit-style-underwear product. Energous made a pretty big deal about the announcement at the end of last year and at CES this January, so it was an equally big deal to see that disappear. Today on Twitter, Alexandros Roussos responded with a comment straight from Myant on this:

First of all, thanks to Alexandros for getting this information straight from the company, there's a treasure trove of information just in those few lines. I have not confirmed this myself, and in the absence of an official statement from Myant, I'm going to take this statement as accurate, should that change or Myant clarify, I'll update accordingly.

Efficiency - Valid Excuse or Covering for Poor Performance?
First thing to note is a confirmation they've dropped the contact wireless charging. That's an "ouch" for Energous. Second is that the reason given is "charging efficiency" - which is a bizarre reason to give. Battery life is around 6 days, and likely around 0.5 Wh capacity, which means around 30 Wh per year, or ~0.4 cents per year of electricity at the average price of 12c/kWh at 100% efficiency. That means 4 cents per year at 10% efficiency, and 40 cents per year at 1% efficiency, for a product that's a few hundred dollars. This is not a reasonable excuse based on efficiency, so maybe they mean charge rate?

How long is someone prepared to wait for charging such a device? Well a Fitbit is around an hour, give or take, so it shouldn't be much more than that every 6 days. Energous claimed around 5 Watts or more charging for the contact system, which would easily charge a device like this in less than an hour. Does WattUp charge at lower rates than this for smaller devices? If someone had to wait 10+ hours for the charging, that would be a good reason to have to have 2 devices (Interestingly in their old package Myant included two trackers, while in the current package it looks like they sell only one. "Use two modules interchangeably for the full 24/7 experience" they say.) A slow charge rate would definitely make it questionable as a consumer product, and I think this is more likely what they mean by "charging efficiency".

It seems to me with this statement that Myant have confirmed that the Energous mini WattUp is not a viable solution for mobile electronics - the core market it's touted as being designed for. That's pretty damning for any product.

Incompatibility - Despite Energous PR Claims Otherwise
One of the very interesting things is that Myant claim that they want to "bring a product compatible with distant charging" which is ridiculous as that was touted as an an inbuilt major feature with the mini WattUp - use for contact charging now, then move to the at-distance charging with the same device in future. In-built future proofing! To quote from Energous' own press release:

"All WattUp-enabled products will support seamless transitioning from charging via Miniature WattUp transmitters, to future stationary in-room transmitters that will offer wire-free charging with mobility at a distance. The result will be a complete wireless charging eco-system."

Has that compatibility been broken? I do wonder if the recent change to 913 MHz for the mid-field system killed any hope of compatibility. (Yes, I know, I'm saying that a unavailable product is now incompatible with another product I'm saying will never be released, I get how ridiculous this is).

Have Myant inadvertently confirmed that the "WattUp eco-system compatibility" does not exist?

At Distance Charging Convenience
The last statement of the charging convenience of "at distance" is ridiculous. If the contact method is inefficient, by definition the at-distance method will be far worse - that's both basic physics and common sense. You won't lose "some" efficiency, you'll lose a lotEnergous' own numbers for their mid field system shows charge rates between 30 mW and around 100mW, so between 5 and 16 hours to charge, while standing in a small region around 50 centimeters on each side, always facing the transmitter. Yes, that's practical...

Maybe it's for just throwing on the nightstand and charging at-distance that way while you sleep - in that case it's no more convenient than contact charging, but a lot more inefficient!

Confirmation of Impracticality?
The response from Myant is welcome, to me it confirms that the WattUp has been dropped from the "flagship" Energous named customer, there is no replacement, that the contact based WattUp system is likely too inefficient (slow?) for most consumer electronics, and that the promoted inter-system compatibility does not exist. A few lines from Myant, and it says a lot to me about Energous' product overall.

Update:
A few minutes after posting, Alexandros made the following statement on Twitter, that there was some paraphrasing in his response. You should take that into account when reading this post, however I think the main points of the post still stand.

Has Myant Dropped Energous Wireless Charging?

Over the last two years I've covered Energous in some depth, pointing out what I believe are excessive claims as to performance and capabilities, based on things like "laws of physics" and "FCC regulations". The company has often said that products are merely 18 months away, and have done for at least 4 years, leading to many claiming that their technology would never see use in a real device. To silence critics, last November Energous announced their first product with "WattUp" charging technology - clothing from Myant. In the press release, Energous' CEO said:

"Myant is a market leader in delivering a textile computing platform and signature line of smart apparel and we are excited that our WattUp technology has been chosen to power their sensors. The ability of the WattUp technology to charge its receivers in a variety of different ways - depending on the specific product, its use case or simply user preference - is just one of several key differentiators we have secured within the wireless charging industry. By providing this technology to Myant, Energous is growing its ecosystem of WattUp-enabled products and helping usher in a new era of smart apparel."

(Now if you're wondering what this product actually is, it's pretty simple, it's a Fitbit-for-your-underwear. Interestingly it was then, and still is now, for "pre-order" only, you can't actually get your hands on this product yet.)

Most read this press release as "Myant is going to use our at-a-distance wireless charging in this product" and a stamp of approval from an actual company with products. What he actually said though, was that WattUp will be used - this is the marketing term that includes both their "ineffective at distance" charging as well as their completely separate "works only when in contact" version to confuse people. They can claim 5 Watts charging with WattUp, meaning their contact version (about the same as existing, prevalent, Qi based charging) while allowing people to assume they mean their not-available at-distance charging is used. That at-distance charging method can supposedly charge at around 100x slower, while needing a safety cutoff if you come with in 50 centimeters. They used this technique to bamboozle tech journalists at this year's CES, I reported on that here.

If you looked at Myant's website back during this announcement, you'd see graphics like this:


It's clear there's a wireless charger, that it's WattUp from Energous, and that wireless charging is a big selling point for them - such a big point that there's no wire included in the package. The Myant CEO , Tony Chahine, made a huge point about that this January in another press release:

"We created a transformational ambient interface through our SKIIN products. They provide bi-directional access to the human body for the purpose of connecting us to our loved ones and ourselves through IoT. It is important to me that advancements in innovation reach everyone, including the elderly, the sick and children. The seemingly simple action of plugging, unplugging and manually charging could alone be the very thing that will inhibit a user from benefiting from technology."

So a huge win for Energous and helped boost their stock price during their big announcements at CES this year, giving ammunition to their supporters to silence the critics, and helping Energous' insiders reap greater financial rewards as they began to sell significant amounts of their stock.

How's this wonder product looking now? A visit to the same Myant page today finds this:

As you can see, all reference to wireless charging is gone - nothing in the product package image, no major selling point. Worse than that, it's now "High-Speed Charging" that specifically says "plugin time", and the charging cable is clearly visible. Go to the press release page, and it's seemingly scrubbed of all reference to Energous or WattUp barring a single comment in one story. 

Myant look to have dropped Energous' wireless charging from their product, even the "in-contact" version Energous have been touting for some time. Why would Myant do this, especially when they have likely already accepted money for pre-orders based on the presence of wireless charging? It would be hard to do anything other than give a refund based on not-delivering as advertised, and is a situation most companies would avoid as much as they could. Did Myant announce the product without actually testing, or did later testing find flaws in WattUp that made it impractical and force a fall-back to the boring but 100% reliable wire method? If Myant knew all along it wasn't viable, then that's criminal on a number of fronts.

When did Energous know that they were being dropped from the product? I'm interested to see how they handle this in their next earnings call - maybe in the same way they handled the departure of the Founder/CTO in the last call, which was to simply ignore it completely.

I'm not surprised by this happening, I never expect to see a practical consumer product for sale using WattUp. Announcements like the Myant Skiin line make it appear there's a route to productization for the technology, and simply extends the game of boosting the stock price. Personally I doubt Energous want there to be a product out there, as it exposes the technology to the public for them to dissect and prove what it actually is - like the FCC approval data, it lets you see the man behind the curtain. Once that happens, the smoke-and-mirrors just doesn't work anymore.

So sorry everyone, no wireless charging of your undies!
