Thx Bro. I'm going to send my cv right now.

By the way; Transferring energy via ultrasound is quite dangerous for us -flesh and blood creatures- because if somebody get in the way of focused ultrasound beam, their blood may degasify or worse.

Oh, TED Church!

So she "designs" and pay others to do it? That reminds me of Dilbert boss.

Narrow minded people is everywhere, some are bosses that consider narrow minded to an entire professional collective.

Translation:
- Low wages, expect your salary may not come due to "economic issues".
- You are going to live there, expect massive crunching.
- You'll be fired when the project works or is a massive failure.
- Even if you show something doesn't work, she'll say you to keep trying. If you fail, you'll get fired too.
- Your bosses will see you as a bad tool to solve their issues and expect moderate mobbing everyday.

Am I right?

Revealing; well spotted!

She's definitely arguing along the lines of:
  • all revolutionary products were at some point considered crazy ideas
  • this is a crazy idea, therefore it will be arevolutionary product.
And, at 14:25 she can't wait to give negative engineers the middle finger. Translation: agree with her or suffer.

Had a few spare moments to look at what they're "doing", as far as I can see is outfit has managed to piss between 750k and 1.75M up the wall, but has nothing more tangible to show for it than they did three years ago since they gained the funding other than a few more media hits with the same vague and unsubstantiated claims.

I'm in the wrong business.

Yup, great when people just throw money at you and you can piss it away whilst living your fantasy of trying to change the world with your "invention". Looks great on the resume for the next inevitable piss-up-a-flag-pole adventure.
She has raised $13.2M

They were "getting ready to move into production" in Oct 2014:
http://techcrunch.com/2014/10/30/ubeam-10m-upfront/
but a year later and still not a single tangible demo, photo, or info on anything real that might be the least bit viable. But of course it must work because the money comes from lots of big name celebrity tech investors, they wouldn't invest in a turkey, it must be viable, it must!

I don't know if this applies to Meredith's case or not, but I will say that I have learned the hard way that startups will even lie about the funding they have received.  Some of it is contingent, but they will leave that out of the press release and just announce the theoretical total. 

The other thing that I learned about VC's the hard way is that they will knowingly invest in hype, betting on getting their money (and handsome profit) out once the venture goes through its initial vending round where less in-the-know investors are goaded in by securities salesmen. 

Grifters abound in the startup business. 

===================================
P.S.

The moral of this for me is that the presence of venture capital is *zero* indication of due diligence on anyone's part.  It is an utterly different animal than presenting a business plan for a small-business loan.  Venture capital is not there to sell a product.  They are there to sell an *idea* to subsequent investors.  VC is a pre-IPO version of "pump and dump."

The perverted consequence of the above is that in pursuing VC, it is better to have an idea that defies scientific and engineering muster, since it will sound so much better than the market alternatives.  Hence, lavish returns are guaranteed.

It's all about the story.
Girl (yes, fact is they are still novel in the tech field, so it doesn't hurt) with charisma but zero engineering experience comes up brain flash idea, everyone is stunned why it hasn't been done before it's so obvious, it's an ideal utopia everyone wants to believe in and needs, unlimited market potential, something only someone with "left field thinking" could have come up with it, everyone tells her it's not practical, struggle against the odds and the naysayers, bodge up prototype in record time, smoke and mirrors demo at trade show, overcome more struggle and naysayers, get some big companies (Starbucks) to say they want it, get publicity which leads to more publicity, and bam. It's real. It's gotta work because it's obviously gotten this far. Everyone buys in.

You know how it ends  :palm:

Over time, working with manufacturers, uBeam has a method that will allow the battery life to last 10x longer than today’s batteries before they degrade. They can allow manufacturers to use thinner batteries and thus further miniaturize phones.

WTF? - why would you include some more BS like this that's totally unrelated to what you're trying to sell -distraction?

Did the physics actually work? Check
references ? evidence ?

Was there consumer demand? No brainer. If electricity could be transferred like WiFi but as safe as a soundwave we use on pregnant women’s bellies
Nonsensical claim that as medical ultrasound is safe, a higher powered version is also safe.
Quote
and at a price-point that was attractive this is a multi-billion market. Check.
a multi-billion market? really?  how many people are willing to spend significant money because they can't be arsed to plug something in?
How many companies would spend money on infrastructure that will only inefficiently charge one device at a time?
Quote
Was it safe? Well … for starters it is just an inaudible soundwave being transferred – as in the kind also used for women during pregnancy.
..and welding metals and plastics. And disintegrating kidney stones. And surgical tissue ablation http://www.baroquemedical.com/ablation.html

Considering my ears are made for sensing very minute vibrations, and hurt from rather low intensities (~W/m^2?), I can't say I like the idea of beaming intense ultrasound through the air.  That's like illuminating the room with comparable intensities of infrared: you can't see it, but you can feel it, and staring at it for too long will give you cataracts (a very real hazard for glassblowers, foundrymen, etc.).

From April 2015 in TechCrunch "uBeam’s Ultrasound Wireless Charging Is Real" http://techcrunch.com/2015/04/26/kill-the-cord/#.qfhg1c:5lOU

Then 1,000 words of gushing diatribe, in the final paragraph...

"uBeam is still working on a hard science problem where unexpected setbacks can happen. There are plenty of reasons it might not be able to get as cheap, powerful, fast, and safe as Perry hopes."

A debunk here:
http://lookatmeimdanny.tumblr.com/post/101432017159/how-putting-10m-into-ubeam-illustrates-everything

This sounds a bit like buying a soccer club, the value isn't in the club itself, it's that there are idiots around who are prepared to spend even more than you did on it when you come to sell it. The funding bears distinct resemblance to a Ponzi scheme that would make Bernie Madoff proud.

Its worse than that, they want to put dozens of these into every Starbucks, all with beamforms darting all over the place tracking phones, which of course has zero potential of being harmful should they beat:

Well they are right, the physics is proven on this remote phone charging. And the physics says it won't work without rattling itself and your house apart, needing three phase to power it, and being about 0.005% efficient. But at least, when table mounted, your sauces won't get a skin on them.

They cannot admit it's bullshit because:

(A) They're already investing other people's money;

(B) It's their career, reputation and trustworthiness on the line;

(C) They need to be in a position to sell off their tangibly worthless investment to someone else to at least get something back before the cat's out of the bag.

Because of all of these a VC will never admit any investment they make is based on a steaming pile of dog turd, at least not until they're rid of it and have made a positive ROI in (C). I am thus really struggling to define the difference between this type of VC "investment" and a Ponzi scheme.

When it does fail they will blame it on anything but the idea being impractical from an engineering point of view.
And they'll boast (perhaps rightly) about their great beamforming technology and production electronics etc, and how it was "ahead of it's time"  :blah:
I give it another year, tops.
If they are the least bit smart the would have already been spinning off some niche tech from it for other applications. Just like SolarRoadways will have to do, and make into fancy pavements or something, because the whole road concept was flawed to begin with.

Remember VC funding isn't just from over rich individuals, it also comes from other places like our pension pots, so when this fails the likes of you and me lose out too.

But perhaps more simply, it's a scam, and nobody likes being scammed.

Social engineering is all about scamming and fraud. Real engineering is not.

But I agree it is a form of social engineering in the end. While Meredith Perry might be charitably called naive, the VC types such as here http://www.bothsidesofthetable.com/2014/10/30/the-audacious-plan-to-make-electricity-as-easy-as-wifi/ are either knowingly misrepresenting or incompetent, and my money's on the former.

VCs aren't the suckers, we are. They are betting on getting out at the IPO - well before the flaws become publicly known. Howard is exactly correct about the pension funds and mutual funds etc being some of  the prime buyers of these stocks.

This whole mess really has become a form of legalized fraud. Nobody cares if the science pencils out.  Somebody should.

Why the hate?

Hating the impracticality of idea and product is not the same as hating the person, don't make the mistake of equating them.

And if you want to know why engineers aren't exactly sending her xmas cards, watch this, she doesn't have kind things to say about us:

She says at the end of that video 'never give up'. Let's see if she will dedicate the rest of her life to this failing idea.  I say 2-3 years at most and then she will give another talk about how other people failed her.

I can't see any reason it won't work (in theory) - phased array transmitter following the receiving device around. Simple...

Of course, it will be potentially dangerous and harmful if you get in the way of the beam, the overshoot of the beam or even a reflection of the beam, but one assumes they figured that out already.

And you'll need something built into or attached to your phone/device. Much like (wildly successful) inductive charging.. But clearly not a big hurdle for them to leap if they've worked out the other things.

Yup, I can see a bright future for this.

From the online help of Borland Turbo C++ for DOS:

Code: [Select]
|sound, nosound|                     
  ________________
•sound turns the PC speaker on at the specified frequency
•nosound turns the PC speaker off

Declaration:
•void sound(unsigned frequency);
•void nosound(void);

Remarks:
•sound turns on the PC's speaker at a given frequency.
•nosound turns the speaker off after it has been turned on by a call to sound.
frequency specifies the frequency of the sound in hertz (cycles per second).
Return Value: None

Portability:
 + DOS + UNIX + ANSI C + C++ Only +
 | Yes |      |        |          |
 +-----+------+--------+----------+


See Also:

delay
Example (for both functions):


/* Emits a 7-Hz tone for 10 seconds.

      True story: 7 Hz is the resonant
      frequency of a chicken's skull cavity.
      This was determined empirically in
      Australia, where a new factory
      generating 7-Hz tones was located too
      close to a chicken ranch: When the
      factory started up, all the chickens
      died.

      Your PC may not be able to emit a 7-Hz tone. */

 #include

 int main(void)
 {
    sound(7);
    delay(10000);
    nosound();
    return 0;
 }

There is also huge amount of attenuation as well
http://lookatmeimdanny.tumblr.com/post/101432017159/how-putting-10m-into-ubeam-illustrates-everything
Okay, by now we have been talked about what would happened if a body close to beam.
But there is also another issue; If you have a resonable powerful ultrasound beam travel through a thermoviscous fuild -such as Air- self-demodulation may occur.
LRAD uses this principle.

The interesting thing is that the VC wankers who say the physics work don't give ANY documentary evidence that it does.

One individual, admittedly highly under qualified by dint of his physics degree and years of experience in ultrasonics in medical development, is dismissed by the VC, who then fails to give the details of his own "due diligence" other than do say it works.

The only reason the VC is bigging it up is so they can sell their soiled underwear to someone else before anyone smells it. Hopefully t'internet will reveal the truth before some unwitting souls are coerced into it.

Of course they don't, they are technical geniuses who instinctively knew it will be practical  ::)

Why should the VC have to give details of their "due diligence"??? They aren't asking you to invest - it's a private matter.

That's a pretty cynical spin on things. But I get the sentiment.

As I've said earlier, I can't see any reason why this wouldn't work from a science POV - I can see many reasons why it won't work commercially in a 'wireless power of laptops and smart phones' application, but perhaps they have other applications in mind..

Remember VC funding isn't just from over rich individuals, it also comes from other places like our pension pots, so when this fails the likes of you and me lose out too.

But perhaps more simply, it's a scam, and nobody likes being scammed.

Social engineering is all about scamming and fraud. Real engineering is not.

But I agree it is a form of social engineering in the end. While Meredith Perry might be charitably called naive, the VC types such as here http://www.bothsidesofthetable.com/2014/10/30/the-audacious-plan-to-make-electricity-as-easy-as-wifi/ are either knowingly misrepresenting or incompetent, and my money's on the former.


As the above post - it all comes down to due diligence. If the VC's don't practice this and would rather play a numbers game based on what idea / pie in the sky product is trending on twitter then fark them.

They need a lessen in economic Darwinism.

Once the current business model / practice the VC's use disappears, then maybe it'll be feasible to obtain funding without having to give up everything 

What are the current stats on VC funding success rates?   1 in 10  show a return?  no wonder they have to gouge and screw!!

I'm sure the good VC's have a better return rate than 1 in ten, but their rates are going to be set on the industry average.

While the dickwad VC's who do no research (other than social trends) continue to do business, well it kind of screws it up for everyone else.

Let Darwin do his job and screw them.    BTW, I do my own superannuation for this very reason  :)

How are you supposed to make high Q ultrasonic transducers with an impedance close to air? AFAIK they don't exist.

The trouble is, you're thinking linearly whereas you need to think exponentially. Only then will it become clear.

When they write a public article supporting and spruiking the investment and going into systematic reasons to why it's a winner, then yes, they can expect criticism about the reasons they have published.
In this case, I think you can bet your bottom dollar that if they guy had real technical evidence to back his investment he certainly would have mentioned it.

Bingo.
No one is saying it can't work, of course it can, that is demonstrably true.
It's just ridiculously impractical.

Perhaps not. At the end of the TED video she mentioned charging an iPhone  so she definitely sets the expectations higher than just miniscule power.

She is full of it and the TED crowd claps for her. They used to have higher bar.

Why should the VC have to give details of their "due diligence"??? They aren't asking you to invest - it's a private matter.

They are bigging it up for three reasons. Firstly to make those who've actually put up the money behind the VC not feel like idiots; secondly so that they maximise the value when it comes to getting out at later funding stages for other unsuspecting investors; and thirdly to protect their perceived reputation and trustworthiness as a successful investor for future scams high potential opportunities.

After all, you're hardly going to say your investment is a turkey if your intention is to sell it on at a profit.

They are not interested in staying in for the longer term, only realising a profit from their investment in a flawed concept.

We agree, it can work but not in practical terms, not by a long way. But their stated aim is to charge mobile devices such as cellphones and laptops.

The problem we have at the moment is that with low interest rates and mediocre performing stocks globally, there are plenty of people with money to invest in something that is perceived to be better performing. The parallels to the 2000 dot com bubble are worrying.

VCs are all there to cash out at the IPO. It's then a very public matter.  Whether Meredith can shuck and jive her tech to an IPO is an open question. 

Energy fraud in the form of sucker bet IPOs is becoming so rife that the SEC needs to establish due diligence practices akin to GAAP in accounting practices.

(Well, that was embarrassing.)

When I look at it now, there were so many clues to that, that I'm shaking my head at myself - but I worked out why it happened.  Earlier that day I had been challenging someone over alternate energy in motor vehicles and this video just triggered a couple of points of irritation from that discussion.  Result: Inappropriate rant.




I think I'll go clean up my desk now.....
