The universe would explode because that is energetically impossible.

Protip: we've had those since the 1920's.

They have. It changed nothing.

Henry Ford originally prototyped engines that would run off of various things, including fuel made from Hemp. Electric cars have also been around since the invention of the automobile itself.

You have big oil to blame.

how fast does it consume fuel?
how much power does it output?
how heavy is it?
how pure does the water have to be?
how expensive is one to produce?
etc

answers plx

Why we still use combustion engines then?

You'd never hear about it OP, big oil would cover that shit up so fast no one could ever get it noticed.

>>1804929
Identical to combustion engines(cars and such), but just use water instead gasoline.

The world would hit peak water in 200 years.

I would make millions of people die from lack of water and only the richest will have access to it.

I herd u liekd hydrogen engine.

>>1804959
I hear water is pure hydrogen.

No, but not for the reasons others are saying, water is extremely easy to make, becuase oxygen and hydrogen are found abundantly in our atmosphere, the reason it wouldn't work, is purely because of the beuracracy(spelling fail), there would be some sort of hazard to it, nothing good ever comes without it, and so to speak, someone will fuck it up for everybody, there would be too much paper work, and it would eventually banned, our society is awful at changing, and the government, and the ability to sue doesn't make it any easier

>>1805000
It's not that. Change isn't what's required. These technologies have existed since the invention of the automobile.

It's just that those with a vested interest in making money happened to have enough money to buy out the competition so that they could make more money in the end. Same reason pot's illegal.

>>1805041
>Same reason pot's illegal.

>>1805041
Actually change is exactly what's required, though nothing as trivial as elections are going to change anything.

>>1805058
Those with a vested interest in the cotton, wood pulp, and pharmaceutical industries spent lots of money to make it so. Rather than adapting to the hemp market, they attempted to destroy the hemp market.

people would go about their general business unaware of the existence of such an engine. For example, they might post on 4chan asking about it and get repies like this.

convert water into fuel with sunlight only
only byproduct is used up in fuel's usage
only exhaust is water

I didn't think /sci/ were so paranoid; "Big Oil" are more interested in paying the government of niger to keep quiet about oil flaring than cars that make unicorns cry tears of happiness

>>1805161
They're interested in both and have enough money for both.

>>1805161
it's documented. not paranoia.

>>1805109
Pot is illegal because goverment doesnt want people to be fucking junkies.

>POT ISNT DANGEROUS MAN. ALCOHOL IS MORE DANGEROUS. DERPHERP

It all turns around economic competition. Where there is a profit, there is a way.

Things like the availability of the fuel and stuff are involved.

However, even if a technology like hydrogen powered cars becomes economically more viable, there is still the additional costs of converting all of your factories into making these other cars. If you just start selling them alongside normal cars, youre competing with yourself and that can cause a lot of harm to a bussiness (think about if microsoft would make all of its Xbox exclusives available on PC as they come out, the motivation to buy an xbox is gone because you can plug controllers into a PC).

This is why probably in a few years (I think renault announced to have electric cars in 2012) alternative fuel cars will come out at a higher price than normal cars becauce of a luxury status created by the manufacturers. Much later, an alternative equivalent of the volkswagen beetle will come out and will be known as the "first affordable alternative car"

History repeats itself.

>>1805183
lol, wut?

> water powered car engines available
> big oil companies won't let them to be built

This thread is full retarded.

>>1805279
>built

Who said anything about built?
They can't gain market share versus an industry so well entrenched as big oil.
Without market share their R&D is an arduous process due to cost, which in turn means that it takes them longer to become affordable to the average consumer causing a snowball effect.

>>1804941
They would be instantly rich, obviously. Even richer if it could run on salt water.

The people saying big oil would cover it up and no one would ever know are potheads. You may ignore them.

>>1805567
>believes belief in corporate corruption institutes cause to believe anything bad about corporations

Derp. They already have made fuel from salt water. I can't find the exact link that explains everything (it's been a long time and multiple reformats since I've read it) but here is a news article.

http://www.firstcoastnews.com/news/mostpopular/news-article.aspx?storyid=85990

Well in order to turn water into hydrogen we need electricity. So its cheaper to just use gas.
Also its hard to contain hydrogen since its lighter than air and its highly explosive.

steam engine anyone?

>>1805645
those are powered by coal <_<

>>1805607
It says right in the article it's probably not a fuel source... it's just a way to make fire from radio waves + water.

>>1805632
Oil requires energy input to extract and process it, hydrogen requires energy input to extract it from water.

The point is that they are portable energy containers, if we could just drive around with our cars plugged into an outlet while driving we wouldn't need either of them. However that's highly impractical so we need a fuel.

>>1805721
I didn't read this article, though the actual post from him showed how it worked and everything and how it could be used as a fuel source.

>>1805607
Please try not to be an idiot. "Fuel" means an energy source. Water cannot be an energy source, because it takes more energy to break the bonds than you can get back. A torch that uses electrolysed water to burn H and O, is not using water as its power. It is using electricity as its power source. And it's very inefficient.

>>1805721
They're not the same. It takes energy to refine oil, but not nearly as much energy as you get from burning that oil. That's why oil is a fuel.

>>1805771
Derp. It heats up to 1500 centigrade with less energy than is required. Use that to make steam for turbines
Profit

You don't need fucking question marks here.

>>1805785
Oil is harder to get and rarer than water. Take that into account and it likely all balances out in the end.

Yes, of course, of course, what would happen..?
You mean.. what did happen don't you?
