Yes, I know of the people that have invented these things in the past, and have had their idea bought out by the oil companies. Some people have been buried in the Nevada desert, some people got terminal cancer, et cetera, for not selling out to them and instead, they paid with their lives. Big Oil does not want anything like this made, because they want everyone dependent on them.
Also, this car, I found out, was already out in 2008, and we haven't heard anything else about it. I even think this news report came out in 2008, and now it's 3 years later. Haven't heard anything about mass production, or the fact that it even existed until now.
