Steve James wrote:I agree with Fong. Converting wood to energy takes energy; converting water to energy takes even more. Using solar or geothermal or hydro-aero-dynamic energy to do the conversion is the beginning of a solution. However, we still have to worry about (1) the processes and materials used to create the new technology and (2) the by products. If, for ex., if the manufacturing of the new technology is dirtier than the present manufacturing process, we may end up polluting more at that end than at the consumer end. Also, no engine, afaik, is constructed for free or from free materials. A plywood car, for ex., would eliminate one problem but create another. How about all the plastic used in cars to make them lighter, when steel may actually be a better material because it's recyclable.
Personally, unless the water car runs well on dirty, undrinkable water, it will put a strain on water resources in the few countries where drinkable water is plentiful. True, the earth is 75% water; but only 10% or less of that is drinkable, and its not evenly distributed. Running a car on water in Nevada might end up being more expensive than importing gasoline. Imo, water is not a good solution at all, unless the water is recycled.
If cells can be produced that converts water to hydrogen, uses hydrogen to produce electricity, and produces water as an exhaust, then it would seem more effective (to me_ to use such a device on a larger scale than a private car. Then, sell the electricity to consumers to run their autos. As far as solar, it's the obvious source of energy. Nuclear might be fine, but it has a terrible waste effect --Besides, it's used to produce electricity, and we have plenty of coal for that.
How come some rich guy/gal/group doesn't have a competition to produce a solar car that will take 4 passengers 100 miles at 60mph for 2 days in a row without any form of recharge --and would cost 20,000 to produce.
Somewhere along the line electrice current needs to be used to get the hydrogen from the water...
