I have a problem with water design cars?

Question

Lets say your car runs on water it will shoot steam from the exhaust pipe, won't that just mean more black ice for other drivers when the temperature goes below 0 'C, causing more black ice on the roads.

Answer 1

Why not go with the world's cleanest car?  It runs on compressed air and should be out this year.

Answer 2

For those saying 'a car doesn't yet runon water!' have them research the Joe Cell.

And, research what exactly happened to Joe, who came up with a car that DOES run on water.

.

Answer 3

SULTON  Sir you are insultan me. cos cars can not run on water alone.

Answer 4

Ummmm - If you know about a car that runs on water, how about letting the rest of the world know about it.

Answer 5

Okay, first off, i think you have the wrong idea on how that car would run. Even if it did emit steam, why does the exhaust pipe have to point at the ground? And even if you were right, which you aren't, don't you think that's a pretty small price to pay for a vehicle powered by the world's most abundant resource?

Answer 6

The air car has been promised for over 10 years, it has serious technical problems, one of which is the freezing effect of releasing compressed gas.

water is not a fuel.

The infernal combustion cars produce significant amounts of water vapour, along with other problem gasses and particulates.

hydrogen can be produced from water, and when used in a fuel cell produces water as a waste product.

More serious than the problem of black ice is the increase in damp conditions which affect building errosion and human health, especially in poor neibourhoods along main arterial roads

Answer 7

You may be thinking of fuel cell cars (including those powered by hydrogen).  The 'waste' product is indeed water (but this is not the power source- like current cars are not exhaust powered, carbon monoxide powered, or even smog powered).

Consider this- current cars release considerable amounts of water along with their other exhaust products.  This seems to cause no extra problems.

The amount of ambient moisture in conditions required for black ice (or indeed any roadway ice) far exceeds the water produced by any vehicles nearby.

Answer 8

Cars cannot run on water.  I wish people would stop bringing the nonsense up.

Answer 9

The hypothetical water-fuelled car has two origins. The first is the electric car, using hydrogen cells as power. The other is a very high temperature combustion engine.

The hydrogen cell has a problem in terms of recharge. One needs loadsa hydrogen!......... not a lot to be done about that!

The other is somewhat more interesting.

Water explosively decomposes at temperatures around 2000deg. This means, if you could instantaneously raise the temperature of water, in a cylinder, that much, then water could be used as a fuel. There is a not so slight issue, that water explosively reconstitutes, once the temperature falls.

The best solution would be, then, to use super heated water to drive a 2 stage turbine. The higher temperature driving stage one and the resultant superheated steam driving stage 2.

The problem with such a system would be the need for absolutely pure water. Therefore, in such a system it would be prudent to collect the exhaust water and recycle it in an enclosed turbine system.

The obvious solution to the super heating issue would be to use a laser-powered plasma furnace.
