I actually wrote a few blog posts debunking the feasibility of the solar road, so I'm well aware of it and I may not be an engineer but I was a scientist once upon a time and I'm pretty handy with a soldering iron - uBeam seems like something else entirely. There's a very good idea inside of uBeam's probably misguided goal to act as a phone charger, which from what I read, is a big part of their pitch to VCs.
