It would take God himself to change any of the immutable, set-in-stone facts below:

1. Seven billion people cannot read the word "UBeam" without instantly knowing that they must be sold an acoustic charging solution, and would be confused and never buy anything other than an acoustic solution from such a company.

The idea of "UBeam" ever selling anything other than specifically an acoustic solution is as impossible as the idea of a Tuberculosis brand of cough medicines. It's happened before: https://en.wikipedia.org/wiki/Ayds , a brand of appetite suppressant candies which enjoyed strong sales in the seventies and early eighties. You can imagine what happened after that.

Clearly it would take God himself messing with the minds of everyone on the continent before the syllables "ultrasonic transducer" weren't called to mind whenever anyone read the word UBeam. How can it mean anything else? It can't.

2. The Founder would instantly be imprisoned for shipping any wireless product that did not use ultrasound. No company has any right to pivot to making the exact same thing in an even slightly different way. The founder would be imprisoned so fast the trial could be argued in three days and a grand jury could make a decision in seven to ten minutes. Actually, I doubt even God himself could change the mind of a district attorney on this one.

3. $24 million is not enough to ship a wireless charging solution. Except ultrasound. This isn't something SMALL like the $5.5 million NASA just awarded Firefly to launch a small satellite to space -
http://www.mynews13.com/content/news/cfnews13/news/article.h... -- we are talking about building something, say, as demonstrated in 1893 by Tesla, and ON EARTH. How would you do that with only four times as much money ($5.5M * 4) and change as a satellite launch, where by change I mean a remaining $1.4M ($5.5M * 4 + $1.4M = the $23.4M raised.) When you have a global headcount of twenty engineers on staff to maintain. God himself would have to change the rules of accounting so that twenty engineers and twenty million dollars would make it possible to ship any product. (Except ultrasound.) It's impossible.

4. No consumer wants any wireless charging solution, except ultrasound.) God himself would have to change these preferences so that people who wanted to charge their devices wirelessly could do so even if the technology were a hair off of what UBeam started with. It would be as absurd as thinking that anybody who had been buying a spinning-harddrive music player would also buy a flash-storage based music player from the same comany! In fact, I think God himself could not change people's preferences this strongly - after all, He has maintained free will.

6. No wireless charging solutions are possible. (Except ultrasound.) Now, it would be silly to even suppose that God could change the laws of physics themselves, just for one company. But let's assume that He would. It would take God himself to turn something that Tesla's photographer photoshopped into his studio, and make this magical parlor trick function. Would God step out of his way to make any other form of power transmission possible? No!

....

But Oh, if somehow God could step in and save this startup! It is as though they were stuck in a prison of their own devising; except it's not psychological, they are not free to step out of it. It's part of the laws of God and the physical universe.

Tragically.
