Or moderately priced sea-water.

There has already been thing's like this on several other site's, The next generation fueling systems will either be ran off of energy from the sun, Called Solar Energy, Or thing's will be ran off of Hydro Electric current's, From rivers and such, They will even be making new kind's of cars that you put your trash in, And it runs off of that.

Don't worry next generation There will be many different way's to get your rescources.

Name 5 after we run out of oil.

Solar Energy
Hydro Electric
Solar Combustion
Battery Energy
And left over rescources

In Poland 2/3 cars are modified to be able to run on Liquified Natural Gas, it is much cheaper then fuel and the car makes the same sounds while running on it but theres a catch, first of all, it damages the engine more then fuel does and if somehow you get a spark into your tank... you're screwed... really bad...

Hamsters in wheels.

How about wind power, we could have little sails sticking out of our cars.

Voyager... theres a reason why this was posted in SERIOUS discussion

How is water and batteries going to run our cars, boats, ships and everything else? Solar energy isn't constant enough to provide a source of energy to sustain our needs.

How about this one:





I'm serious about the sail thing though. It seemed to work well for ships...

Solar energy - too finiky. If you get a few cloudy days, you're screwed. Also takes up a lot of land and space, not to mention money.
Hydro electric - expensive to build, and to transport the electricity. Not that it can't be done - Hoover Dam is a good example of one. The enviromental damage during the construction is quite devastating though.
Solar combustion - Huh? Explain.
Battery energy - and what do we charge these batteries with? Or do we still mine for the metals that we use to make disposable batteries, and continue to erode away our resources?
And left over resources - Explain. Which ones? How accessible are they? Cost? Yield? Etc.

How about storing power in batteries + solar power... I think they do it today. And solar power for example, solar powered cars don't take up too much space.


I think the key is to reduce oil use until we can find a better solution, hybrid/electric cars, nuclear power, etc.

Engines in the future shall run on inprobability. (HitchHiker's Guide)

Batteries don't run everything. You guys think it's as simple as "putting" power in batteries and storing them for later use. Much more complicated then that.

Gigantic rubber bands powering really lightweight cars...this idea was inspired by those crappy paper airplanes you find in stores. But ofcourse, it won't really work that well...but you never know, someone might actually be that cheap....

Well... Batterys are chemical reactants... you need those "damn metals and shit" to run on them. Plus batterys don't even generate enough electricity to run even 12 miles.
Nuclear Energy? sci-fi. If your talking nuclear energy, your just another geek that knows nuthin but reading halo 2 shit.
I say this. CAR SHOULD RUN ON MY ASS'S FART, CAUSE ITS STRONG ENOUGH TO KNOCK OUT ATLEAST 5000 PEOPLE IN A SINGLE SHOT!

Yeah, because it's not like we use nuclear power at ALL today...

...

Everybody thinks "nuclear power" mean huge ass nuke from hell. I mean, come on, nuclear power has been used in things like a pacemaker.

IIRC, the airforce is experimenting with Hafnium-178 reactors to use on aircrafts. Apparently, if you shoot an x-ray at it, it gives off an excess of gamma radiation that can be used as fuel. And because it only gives off gamma radiation, and not neutron radiation, it requires less shielding.

cool, but what happens to the person on the cockpit, getting hit by all that radiation, wouldn't he get KILLED?!

How about ethanol fuel? I heard that Saab's new engine not only handles ethanol, but uses it in a way that is more efficient than gasoline. Not to mention it's cleaner and almost infinitely renewable.

Radiation shielding. Gamma rays only require a meter of lead to shield it IIRC from chemistry. Neutron radiation requires too much shielding - it's not feasible on a plane. That's why the Hafnium reactor could work...and the air force will probably stick it on some sort of uber secret spy plane of doom. There is a reason why results from tests/experiments of this idea is highly classified...


Ethanol is the alcohol you find in beer. So it usually comes in the form of a gasoline-ethanol mix. I believe that most cars should be able to run on it depending on the fuel mix, but it was too expensive to replace actual gasoline. Here's a bit from wikipedia:

I finally got around to reading this shite, and it's good stuff. Point taken about the hydrogen. This ATP stuff sounds alittle ify to me... I didn't see anything there where they converted it to mechanical or electrical energy..... Some things just work better in nature. (take butterflys and birds for examples...)


I didn't think so... where then?


I think they're called synthetics..... "idiot"
Hydrogen would not work. Rantent already displayed that.


Definutely. You should hear some of the stories people with connections get...


Please explain how and you'll be an over-night millionaire and possible savior of the planet! The most famous man of the 21st century, and a legend beyond that.


Solar panels don't produce enough energy to be a viable substitute for fossil fuels...

That's not the point. Next-gen fuels aren't really the rush, the rush is to get them in before we cook the planet to a medium-well state.


As to the comments about batteries and such, they'll never be able to replace fossil fuels and that, because for one you have to charge them, and more importantly they'll creat DC electricity only, which is not only absurdly inconvenient, but also very uncommon nowadays (except in small applications of course).

My guess would be Laser Fusion. The Earth still has about 50 years left of petrolium, so there's enough time to mass produce this.

Basically you take several high powered lasers and concentrate them on one point. Because lasers are highly concentrated and heated up beams of light, it will be much easier to fuse the particles. The current strongest laser can burn a 2 inch hole through a meter of steel. Concentrate several lasers(not as high powered) and all those particles traveling at super-high speeds will eventually fuse or fission. Basicly, you won't fuse the photons, you'll fuse the gas which is in an enclosed area.
It's cheap because you only need to fire a couple of lasers to initially start the process and you can get a large amount of controlled energy.

Well, the easiest next-gen fuel to use is probably alcohol. Most cars can use alcohol, because it burns like oil, I suppose. Plus, you can grow alcohol, making it renewable.

Hydrogen can work, and will work (once they get it down) Because all they need is an engine to run it, and a storage container for the Hydrogen.

It'll work, but it'll be just as bad as using gas.
