I never said it was impossible - only inefficient. If building an inefficient car is your definition of success, then you are, of course, right. It's not my definition.

Well...if by inefficient you mean increased costs to convert and operate this system - you may be right. Of course, you probably mean inefficient as an system to store and release energy. That I don't know. I'll leave it to the experts to make that determination.

But if converting significantly reduces air pollution in a congested city - say, Denver or LA - the trade off may be worth it by reducing health care costs and loss of productivity associated with air pollution.

The safety of the storage tanks was of immediate concern when I first looked at this technology. The carbon fiber tanks address some of these safety concerns. And real life auto accidents and Hollywood movies remind us that gasoline is not without its hazards.

I think the future will have many competing engine technologies to choose from...In the future, gas stations will adapt to these many engines types and just sell a variety of fuels.
