Chevy Volt

I'll bet a replacement battery pack costs more than 5 of your Hondas. I'd also like to know how much it will truly cost on someones power bill on a monthly basis.



Agreed camd64, there's got to be a better way. I'm a big fan of photovoltaic cells and I have done quite a bit of research on it. Free electricity from sunshine? How cool is that, lol. No moving parts to wear out and zero maintenance. Anyway, aside from their cost, the biggest problem is storing that energy. Again, we're back to the battery issue. If someone could design a battery that would give back even 90%-95% percent of the energy that was used to charge it, store it for a month and not be affected by cold weather they'd be multimillionaire. Presently, any decent size battery's capacity is only 35% @ -20F vs. room temperature.

You should look into solar thermal technology. Its more efficient than photovoltaic and the energy can be stored as heat at night time in large tanks of superheated liquid salt to produce continuous reliable power. Plus its beautifully simple in that it works by just concentrating solar energy and using it to run a conventional generator like a coal or nat gas plant would. Regardless of the global warming debate, fossil fuels are FINITE and will be depleted in the coming decades. If we don't to revert back to a pre industrial society we better get a move on more sustainable energy sources.
