I looked into uBeam a while back. The technology is unproven and unlikely to work because of basic physics. (They are trying to transmit energy using ultrasonic sound and it usually has severe health consequences for any significant amount of power delivered.) The CEO, Meredith Perry, delivered a TED talk[1] which was nauseating. She was basically saying it doesn't matter what the experts say, if you're a plucky disruptor you should just follow your half-baked ideas.
