The "Water Fueled Car"

[Doc]

Water is a molecule. You can't just "filter" out the hydrogen like you can filter out rocks from a pile of dirt. It takes a reaction to seperate them. In this case, it would take an endothermic reaction because it requires energy. Furthermore, you wouldn't be emitting oxygen, you would be emitting WATER - the product of burning hydrogen. So what we have is an engine that starts out with water, eventually to produce water - and since no process is 100% effiecient, you would just be losing energy. In fact, even if it WERE 100% effiient, it still wouldn't matter because you would be getting nothing more than what you put in.

If you had an engine that seperated the hydrogen out of a given amount of water, then used that hydrogen as fuel for the engine to seperate more hydrogen, it would not have enough energy even to process the same amount of water as before - let alone get enough energy out of the process to do actual work - like moving a vehicle down a highway at 65 mph.
Laugh out loud. That makes absolutely no sense. First you lose energy creating mechanical power from chemical potential, then you lose more converting the mechanical to electrical, then you lose more converting electrical to heat, then you lose THE MOST converting heat into mechanical energy! If you notice, we already had mechanical energy in the second step of the process! Do you have any idea how "hard" (i.e. energy intensive) it is to boil water? It has one of the highest energy/temperature ratios (called specific heat) of all compounds.

I have no clue what so ever how this stuff works, but in all fairness, until you make something better, I don't think laughing at it is a good idea.

The steam engine is a lot more complicated than I can explain. It uses fuel to generate electricity to boil water. It burns a lot of energy getting the car moving. Once the car is actually moving, fuel consumption goes way down and the car produces most of the electricity it needs to keep the water boiling as it coasts. There are wires running through the boiler that stay red hot from the electricity and keep the water around them very hot.

Now, I can't explain it, but the issue of what you describe was addressed. The steam engine is specifically used to provide more power than what an electric motor offers. In theory, this system could drive a loaded delivery truck, and the heavier the truck is, the better it can coast. Steam engine assist would be available for hills and such.

I don't recall if there were electrical motors powering the wheels or not. Might have been. I just remember the steam engine bits and how it provides more power for going up hills and what not.
