--- Quote ---“It’s something we’ve discussed, how much less scrutiny we would face if we were men, how much more implicit trust you’d get. But there’s nothing you can do about it, and talking about it makes you sound kind of silly,” says Meredith Perry, founder of the wireless technology startup UBeam..."

It's remarkable that she makes this claim, given the amount of investor money she was able to raise without any evidence of a working technology whatsoever.  Seems that she had an abundance of "implicit trust".

Yes, she had a stunning amount of implicit trust because she was a fast talking young female blonde in tech, even Mark Cuban admitted as such in an article that being young blonde and female was a part of it. Her inability to realise why she got as far as she did and as much coverage as she did is stunning.

Someone trying to light a red LED with US. The 10A bridge rectifier is probably quite lossy at 40kHz. :)

This idea has GOT to be worth at least $31M in VC funding, a TEDx talk, crazy media coverage, and surely is a Trillion dollar idea?
Mark Cuban might want to invest perhaps?

Probably bridge rectifier not needed since they could use instead additional LED connected in anti -parallel to protect each other against LED low reverse voltage if they worry about, like in attached image ;)

I've sucessfully used many years ago magnetic transducer to convert background noisy environment sound energy into electricity, so nothing new :)
