Answer 2

petrol doesn't produce steam. It produces power through burning. And there is a guy who has made a vehicle that runs off of water. He's also made a torch. He is currently making a humvee for the military that runs on water as another test subject. He said that in a 100 mile round trip, he uses 4oz of water. He uses an electrolosis to produce HHO gas from the water and that's what burns creating the power. The 3rd source has a link to the actual Fox News story done on this guy.

Answer 3

Well, compare the results from lighting a few ounces of gasoline on fire to what happens when you try lighting a few ounces of water on fire. Water is already in its lowest energy state - you can't extract any energy from it except in a fusion reactor. One might as well propose to solve the problem of the lack of oil and global warming simultaniously by building a car fueled by atmospheric carbon dioxide.

Steam engines require an external source of heat. The larger steam engines are some of the most efficient engines out there, but trying to build a lightweight steam engine costs you a bit when it comes to efficiency.

Answer 4

Extracting energy from water requires heating it to make steam.

You must burn some kind of fuel to make the steam. Burning a fuel such as petrol to produce the energy directly, is much more efficient than burning wood, or some other fuel to make the steam.

Answer 5

Water won't be able to be used as a gas. that is an inert compound. as a thanks to transform it to a gas takes an excellent form of ability and there there's a storage problem. so as that leaves 2 strategies to skill a automobile with water, inertia, or exterior combustion engines. Steam powered autos were for sale years in the past and were swifter then the interior combustion engined autos. even with the undeniable fact that cruising distance became fairly restricted and cleansing the boiler became an problem. maximum drivers have issues holding the gas tank comprehensive of gas, it would want to be perplexing to imagine to days motive force attempting to make positive the boiler became secure. An inertia powered automobile automobile might want to ought to carry water extreme adequate to get the momentum necessary to bypass the motorized vehicle. Being that tall can make it impractical pondering overhead obstructions and also it would want to have an exceedingly extreme center of gravity. no matter if the clearance problem were addressed it would not cope with very sturdy and may want to be very heavy.

Answer 6

Because the car companys say that there is still a ton of oil left to be used and they want to use it up until the very last drop so they can make as much money as they can. As well the car that could take hydro has a lot of work left (they need to find a way to make it not blow up when the car gets hit)....

Answer 7

It can!
-but have you seen the price of bottled water recently? $1 for one little half liter. That's more expensive than gas.

Just go on and pour some fine bottled water into your gas tank. Car should run great. Don't use the stuff out of your tap, as it has too many impurities and will clog your valves.

Answer 8

Water is using in the steam engine. And if it is petrol, diesel or electrical engine then you will have to use the petrol, diesel and electricity accordingly. I think you will learn if you study more.

Answer 9

Because they have not yet been able to figure out an efficient system of breaking water down into hydrogen and oxygen and then use the hydrogen for locomotion.

Answer 10

If we had water powered vehicles, we'd have rain clouds following us around all day from the emissions.

This would not sit well with motorcyclists especially.

Answer 11

first of all you need petroleum to boil the water
second of all it was used in the last century.it was not efficient.
a car was invented in japan some five years ago that works with water with different system(not steam) but not official i don't know why (they say arab countries paid them a fortune worth mone so they can sell their petrolem)
