Crude oil will run out someday soon. Cars that run on Hydrogen and fuel cells are being developed but what will power ships and aircraft after oil runs out?
Anyone know anything or have any ideas?

cars already run on hydrogen most likely they will use nukes or use hydrogen

Corn oil!!! And no problem with fuel.

well once cars stop running on oil, then the reserves will be lengthened for a time, long enough to find another fuel.

Nuclear power in cars. Isn't that dangerous or expensive?

most likely they will use nukes or use hydrogen

1 reason i wouldn't put a nuke in a plane: they get shot at. and the same for nukes in cars. cars wreck. what ahppens then? massive fallout. no my friends, the reason ships and subs can run on nukes safely is that they dont travel among/over large population centers, and they don't get shot at as much. hydrogen fuel cells yes, but the power output has to get up there before it will work in planes. the fuel density of petroleum is still wonderfully high compared to other sources of energy.

yes and yes.

Some kind of Nuclear or Atomic power that's for certain.

radiothermal isotopes are a possibility but then you must cool it somehow...

i was meaning about boats not aircraft NMS
but i share ur view on plnes and nukes
bad combination
theyd use an ion engine mabye cause it runs just on electrikery

yea but where does the electricity come from?

Hydrogen is the way to go, because its so common. That, or solar power + batteries.

you make me laugh dude, batteries? yea right!!! . try getting the SR-71 to go mach 5+- on batteries!! HAHA LMFAO!!

hydrogen doesn't have the fuel desnity of petrol yet. WAIT, we can use powdered water!!!!

u know u can use the ion engine just using electricity from the battery becuase they use it on probes into space

I didn't say what size batteries, now did I? Electric cars was what I was thinking, except that the main way to recharge them would be with solar power. It could work with ships, too. You probablly are right, it most likely wouldn't work well with aircraft.

I wasn't saying get a crapload of D batteries and strap em to your car.

It all comes down to fuel desity, or how much power you can get out of a given amount of a certain fuel used in a certain way. But another factor is how quickly you can demand more or less power from the fuel. some fuels can provide a lot a power but take a long time to produce max thrust. i've explained this as best i can....if anyone is unclear i'll try and elaborate more....

The body's bomb is the very terrific in Israel. if someone used the nuclear body's bomb, many people could be die.
I hate the war, I love the peace.
But, I am a soldier. I must obey to the commands. I can defeat the any of enemys(include: the USA).

I think the future fuel for planes will be Hydrogen Fuel Cells. The only problem about those right now is that we only get as much energy out of the Hydrogen as we put in. As for ships, i think that they will continure to be Nuke-Powered. It just seems alot more economical.

To get hydrogen dont they have to use electricity in electrylosis or something

I think that the most fuel is water. Because the water is made up of the Hydrogen and the Oxygen( H2O). The hydrogen can product the more power for the human. But the key promble is how to get the hydrogen and oxygen in the water?

Ion engine can only be used in space. It is almost imposiblr tyo use it in the atmosphere.
