Picked this up, hope it isn't old news:

Just one question, doesn't 'Hydrogen + Oxygen + Fire = BANG' ?
-
heh, we made an hydrogen car:
(http://www.annso.freesurf.fr/H2O_PSA.gif)
funny, it's a fireman car, btw :)
-
Reminds me of the engine tech I heard about 10-15 years ago or so, where this nobody inventor got a working hydrogen engine, but it ran in reverse to what the article above outlines. You'd pour water into the tank, it'd break it apart, use the hydrogen for energy, and pump pure oxygen out the tailpipe.
Heard the guy got bought out and silenced by some big car company. Jerks.

doesn't surprise me much.:doubt:
-
human greed....blech, makes me sick to hear about stuff like that.
Just because they will make more money they silence anything that can cut their profits -_-
But as for the car, it's great news :)
anything that can improve the cars we have nowadays, and at the same time get rid of the petrol need, thats just simply superb
-
Well there go the muscle cars and the drag racing :(
-
It illegal to have electric cars in north America now, only hybrid Gas/Electric is legal.

Same goes for petrol and air though :) The important thing is keeping the reaction from ever being dangerous to the people around the car.

Why? Many drag racers already run on methanol cause it's a better fuel than petrol.

Say what? Where are you getting this from? Not that I'm deny it, it just seems pretty insane, even for a country run by oil giants.
-
funny, I see people in them all the time (mostly on TV :doubt: )
so is there anything new about this or is it just an overview of fuel cells for those who wern't paying atention.

:wtf:
ever heard of golf carts?

Methanol is not hydrogen or burns even close to it...

I know (Almost certainly better than you - I'll tell you the story one day of exactly why I know how well methanol burns!!) but you're acting as if this is the end of everything. That's obvious nonsense. When unleaded petrol became the norm there were people saying exactly the same sort of thing.
Even if it was true you can still get four star petrol almost anywhere. I doubt very much that hydrogen powered cars are going to replace petrol until they can give performance close to that of petrol.
-
Oh, there's no doubt that hydrogen is gonna put the hungry V8's to sleep... if the government puts a stop to it. You'll only see them in collections and possible road shows.
You can't make a comparison between the change from lead to unleaded gasoline and changing an entire system to hydrogen. These cars are going to be nothing like a gasoline powered V8 or an import inline 4. Ever see an electric car do a burn out?
But, you're right, hydrogen power will get efficient enough that performance won't be a problem. Heck, I'm sure they could reach speeds maybe faster than a gasoline, fuel injected engine. But it won't be the same.
No more of people working on their cars in their garages...

yeah, but they isn't used for Transport, only for tranSport ;)

I wouldn't be too certain of that either. Handled correctly a hydrogen engine wouldn't have to automatically be that much nastier to deal with than a petrol one. Sure there are some parts you wouldn't want to mess with (anything involving metal hydrides is a VERY bad idea unless you know exactly what you're doing) but many parts of the engine would remain the same.
As for my point about unleaded. Have a look on the roads. Have electric cars taken over? No. Why? Cause they aren't as good as petrol cars. It will be the same with hydrogen powered cars. They won't take over until they can beat petrol.
Lets face it. What man is going to buy a wimpy hydrogen powered car when the petrol one is better?
-
If I had the money, I would. See, I'm pretty young. And I'de rather live to breathe clean air in my old age than to have A1 SUPAR acceleration.
-
Hydrogen powered buses exist in London or will soon, the picture showed it driving about the place.

Only under pressure. Remember: the Hindenburg didn't explode, it BURNED.

No?
Do you see many stations to resupply electric cars? No? Why not?
I let you guess.
That aside, there's quite a lot of GPL cars in europe. That's already a step forward if you ask me.
-
Hey, that's pretty cool :)
Electric cars are not environmentally friendly because of our poor battery technology.

It's going in the right direction atleast, if a little slowly.
One of the reasons that it goes so slowly is that I doubt the petrol companies are willing to let go it's golden-goose called "petrol" that easy.
The other one is as said performance, but then again I don't know the cababilities of the car either.
But performance is always something that can be enhanced, so thats just a temporary issue anyway
-
A hydrogen-oxygen redox reaction can be pretty effective. What do you think the main booster of the space shuttle runs on?
Of course, the solid state engines are more powerful there, but still.
-
you don't run a car with a rocket, tho :p
-
Same basic concept. Difference is, there you're running it as a reaction drive, using basic Newtonian physics, where in a car you'd probably use some sort of piston or turbine setup.
-
If you could find a more efficient (economic) method of getting hydrogen, cars run with hydrogen would have a much better chance against petrol.
That is the irony, 70 percent of the planet's surface is covered with a substance that has hydrogen but we cannot get it easily! :D
-
Actually, water is a very good source of hydrogen. You can harvest it with a 9V battery :p
-
And is it profitable to get it in large quantities?
Of course not. :p
-
Actually, electrolysis is the standard method for getting hydrogen for industrial purposes. It's also the standard method for obtaining sodium and chlorine (from molten NaCl and brine, respectively).
-
Actually, getting hydrogen is very easy, the pb is to store it, it's very... hargh, I don't have the word: it takes a lot of place if you compare to the petrol needed to generate the same amount of energy.
-
But like I said, you can't get it easily in mass quantities like you can with petrol.
How much would be the consumption of H2 in comparison to petrol by the way? :nervous:
-
In theory, what happens when the water starts getting short? There isn't an infinite amount of it. Anyone know around when we could start seeing water shortages if the whole worlds accepts hydrogen fuel as the fuel of choice?
-
You wouldn't. The output of a hydrogen-oxygen redox reaction is water.
-
That's the thing Rictor, water is the result of the reaction, you extract the Oxygen and Hydrogen from water, the Engine rejoins them, taking advantage of the energy change to power the car. It's completely non-loss iirc :)
-
There is only one problem, where are you going to find the energy to extract the hydrogen from the water? The car becomes "electric" from a certain point of view.

Well, 70% of the surface of the planet is covered of water. I'm pretty sure that's more than the available petrol :p
But anyway, you can get hydrogen in the air too, and probably in other organic materials, and in space, in the sun, on various gazeous planets, in some other rocky planets atmospheres, and even in the "vacuum" of space, but it's really scattered around. Never gonna run pout of hydrogen, or that means the end of the universe ( isn't 99% of the materials in the universe hydrogen, actually? ).
-
That's about right. You don't get anything other than hydrogen until a star fuses the hydrogen to form helium, and you don't get anything heavier than that until later stages of fusion. And IIRC, you don't get anything past iron without a supernova.
-
iirc it's something to do with Ethanol, you can fractioanlly distill it from yeast etc, so it's organic, and quite easy to split or something? :)

Hey dude, good to see you 'round these places. Funny, just out of curiosity, why'd you post this here? :D

I can't wait untill I can get my own fuel cell vehicle.

Hmm, interesting if its real.
