This is the same as CFL bulbs everyone hates. A company just started developing a LED bulb that last 25 years $59. BUT, they have added value of wifi control, can change to any color. They also turn on an off by time or proximity. The developer asked for $500k They had millions in a few days because it's a light bulb people WANT!
Build an electric car that makes money and it will sell. If it can go 200 miles and charge in 15 mins. Or, if you have limited range it has to cost LESS not more. Toyota sells the Prius at a profit. Partly because, like apple, they have an idiot fan base. The Corolla is a far better ROI.
