The "Water Fueled Car"

[Occhidiangela]

I don't really see what you mean with HHO here occhi.

1. What you can think about is a hybrid car. Solar panels continue to generate electricity to do the electrolysis, the hydrogen and oxygen gas get stored (in the car) and used whenever possible. If at some point the hydrogen is finished, standard petrol can be used instead. (it probably requires different engines though).

2. The other option is going to the petrol station and fill up your car with hydrogen (which hopefully is obtained in a more environmentely friendly way). At least this way you only emit water. (but I'm not sure if it is the environment or the shortage of oil that we should worry about most).

"Brown's gas," which is from the link. There has been further discussion on that by others.

1. And for driving at night, eppie? ;) The weight penalty for massive eletctrical storage has been a known problem for about 80 years. There were battery run cars designed in the 20's and 30's that, due to lack of range and considerable weight, were not practical alternatives to petrol driven cars.

2. Your "hopefully" is hardly a sound basis for massive infrastructure development. The cost, both in energy and in "clean up and other associated costs" of "obtaining hydrogen" is no trivial matter.

As to "different engines." The hybrid engine's practical problem stems from whether you optimize engine design for petroleum combustion, or hydrogen combustion, and what the performance penalties are for suboptimizing the design to allow either.

The NAHBE (Naval Academy Heat Balanced Engine) was a design (about 30 years ago) that used a constant pressure combustion system -- it had a domed/conical piston -- and burned all sorts of fuels: gas, kerosene, peanut oil among others. It got about 50 miles per gallon. I don't note a lot of NAHBE's on the streets today. Each alternative fuel, and for that matter each alternative fuel, comes with a price, just as petrol comes with a price.

Edit: spelling, and the fact that I could not find any links for NAHBE.
