Re: Lead acid Versus Lithium, what about Edison.

The article that I read was a description of Edisons development of the battery package for use in our submarines, which I guess he sold the idea to our navy, although I think that they stuck with lead-acid for a while.

Your link lead to another interesting blog,which included comments about the compressed air powered car, and questions about why that has not been developed more. I can explain exactly why, which is that those very high air pressures are very dangerous and no company with any sense at all would put a system with 20,000PSI air, or even just 5000PSI air anyplace where regular people could get at it. And it would certainly take that kind of pressures to store enough energy to drive a car very far. Tata may be able to sell that product in India, but in the USA the tort lawyers would devour them in just a few minutes.

The article from this link makes a ton of sense, Chuck. The hybrid car delivers the features needed by average car owners -- practicality, affordability. EVs are far from that. I find it at bit odd that automakers are investing so heavily in EV development.

Looks like FireFly Energy is still in business under new ownership and producing their  first gen battery. 

Carbon foam lead acid technology.

I agree, Rob. The idea is sensible. I think pure EVs will find a niche, but it won't be at the low end of the market. And it won't be a big niche. Consumer Reports said last week that the Tesla Model S might be the best car they've EVER seen, but it cost $90,000.

Yes, the Tesla Model S also received the Motor Trend 2013 Car of the Year. Obviously, affordability is not one of the criterions for the award. However, the car is getting a positive reception.

Thanks for the lead on Firefly Energy, DavidR. It took me a long time to see your comment, but better late than never. I'll take a look at it.
