What happened to the middle finger to the engineers?

How bad do you have to be to get yourself sacked from your own company. :horse:
CML+  That took much longer than I thought it would.

Its actually very common and generally necessary. The kind of character it takes to build something from scratch is very different from the kind of character needed to run it later as a substantial enterprise. Of course, Ms Perry hasn't got to that stage... :)

"The  kind of character that it takes to build something from scratch" determined, stubborn, obstinate or maybe just stupid.

Some more thoughts on Perry and the role change. Jumped or pushed? And an anecdote about my last day at uBeam.

That's a good read. :)

It might not be the end of ubean yet, but it's the end of charging mobiles by ultrasonic sound waves.

7 years, $37m and up to 30 staff, to prove it's impractical, revenues $0.00, well done to all the investors. >:D  :horse:

From the Techcrunch article:

“For the interim, uBeam’s head of HR and finance Jacqueline McCauley, who joined in 2016, will lead the company.”

That’s like Darth Vader and Hannibal Lector being the same person. Well that’ll save time when negotiating all those compromise agreements and pay offs I guess.

Interesting picture in the TechCruch article.  That amplifier has a pair of chip amps running directly from the 12 volt supply. About 20 watts per channel into 4 ohms at best. The 240 watt rating on it is a gross exaggeration of reality.

That's a car audio amp. These typically include boost converters to produce higher outputs from the 12v car suppy.

I immediately recognized it as a car audio amp - that is how I was able to find the picture of it that I added to the right of the picture from TechCrunch. That amp does not have a power supply. The amp chips run directly from the 12V supply. I have been in car audio since '85 and Pyramid has always been a junk brand. The power ratings are so far off that they are meaningless.

Other than the panicking big investors, no one seems to yet realize that the exciting new phase, is the end of ultrasonic wireless charging. :horse:

Yup, the only interesting thing uBeam has done is their work with the array beam-forming stuff and that is going to only have very limited applications, at least that I can think of. 

Anyone who hopped on the uBeam bandwagon for the wireless charging gravy train is learning that "Arrr, the laws of physics be a harsh mistress."  How predictable.

I wonder if Perry has realized yet that some of those engineers that she loves to give the middle finger to actually understand some things that she doesn't.  (Or at least didn't...  but she's probably still a believer:palm: )

Naw, she just didn't find the ones who were smart enough to build it.  :-//

It's not her fault. She tried.

What would her browser or Youtube history would be like, a bunch of free energy bullshit or something? She's as bad as a flat earther!

Ah, the eternal great unknown of new technologies - "This is cool. Now what the heck can I do with it?". There is a lot of current interest in proximity sensing for collision avoidance, whether its cars or automated domestic appliances. Current solutions use things like crude broad ultrasonic or 77GHz radar beams. Get the price of a narrow steerable beam solution down, and you might be in business. I've seen no evidence that uBeam have done anything that might be low cost, but who knows where they currently stand?

Steerable US beams aren't going to work very well in the moving air around a moving car, or even a draughty coffee shop.

Oh no, a steerable US would be a terrible idea. They might move in next door.  :)
