"The vision system is picking up the pattern on the phone"
I get the impression the vision system just looks for a 1 X 2 white rectangle, the LED viewer is made up of 2.
"the transmitter somehow knows how much energy each receiver transducer picks up and is displaying it on the screen."
Guesswork based on the size of the white rectangle ?
1.5% at their claimed 4m BEST CASE!

There's plenty of folks out there who think that looking at electricity/fuel bills is something poor people do.
just put the thing on a $5 Qi charging pad that is already built into your phone, takes up almost no space, has no safety effects, is efficient, and cheap.

So anything more expensive and less widely supported stands zero chance of being adopted anywhere.

Ok, I won't argue that at all, I could, but I won't.
Let's looks at the absolute showstoppers that make this product impractical, any one of which is enough to entirely sink the product.
- Safety. Even if it currently legal in the US, it's not anywhere else in the world. Even their minimum 145dB SPL is well outside limits.
- Cost. I don't think there is any escaping the inevitable cost of all those transducers. These are already made in mass volume for cars and they are not cheap. This thing needs hundreds and hundreds of them.
- Size. You just can't make the transducers thin enough across the entire surface of a phone to be anything anyone would want. No one wants a brick on the back of their phone.
- The inescapable fact that people use phones lying on the table, or holding with their hand and at an angle etc. This is the thing that should have stopped the project right at the back of the napkin stage.
If you have to put the phone in some ideal position to charge it, just put the thing on a $5 Qi charging pad that is already built into your phone, takes up almost no space, has no safety effects, is efficient, and cheap.
Searching for uBeam on Youtube I note a complete absence of any rebuttal videos, so I might upload just that portion of my latest debunking video onto my 2nd channel so it gets some SEO keyword love.

Now Ms. Perry may not be the most prepossessing creature, but I don't think you ought to talk about her like that.
The only reason to need 'wireless' charging for anything is when someone works out how to keep us humans awake for the full 24hr period (and no, i don't mean lots of Vodka RedBulls....... )

If there was such a massive desperate need for wireless charging at Cafe's etc, why don't Starbucks et.al have Qi chargers built into the table (cost would be trivial compared to uBeam)
