Hydrogen will set u free

I see ya one Hindenburg to 1 gulf spill , what if the Hindenburg accident never happened ? It seems to be safe 4 space travel.

Touché. I'm not exactly fond of non-renewable sources of energy myself, however, as TLAM Strike said, for any source of energy to be efficient you've got to get more out than you put in.
Still, one day perhaps, there's plenty of minds working on it...

that depends on how you look at it. how much enegy is spent on oil from the ground to the pump if that was the case we d still be burning coal , and we would be dead.

If you burn oil to produce electricity to produce hydrogen to "burn" it to run your car then why not burn the oil directly in the car?

To put it in a "subsim" context it is similar to a sub cruising on the surface using its batteries and not its diesels.

BUT

If your electricity is produced not from the consupmtion of chemical energy but from wind turbines, hydroplants, solar panels etc. then you have a more "favorable" series of energy transformations. Definately a good option (not without its problems though). And yes there should have been more research in how to incorporate hydrogen in the "energy greeds".

it s a hybrid ,your getting it ,still ground covered ,what if you use solar or wind ? where did I see it, cows, sun makes grass cows eat grass ,ect ,ect . u missed a point if they get it right the machine will produce it s own fuel till it runs out of water.

[yubba]

what would 1 solar panel produce ? Also cows, sun makes grass cows eat grass.

Its not renewable - some things are simply more efficient than others. The law of entropy dictates some loss in each transformation of energy from one form to another.

Besides - for those that think Hydrogen from H2O is the answer - you do realize that worldwide there is already the start of a water shortage, don'tcha? Know what making water THE energy source will do to that situation?

This planet has more water than we know what to do with , outside of using it like a toilet. Have you seen what a can of corn cost lately.

Where did the water go? I am not aware of any non-nuclear way of destroying water. Water, like energy, is moved or has its state changed. But how would we destroy water in order to have a shortage?

Now if you are talking about a shortage of fresh water, that might be true. But I am not aware of any general shortage of water.

If some of the scientists are right about the glaciers melting, we may not have a shortage of water at all but a surplus.

Look at the gulf oil spill, we drilled a hole to the oil and it came up on its own without the need for pumps. Oil wants to come up to the surface (it happens naturally) we simply give it the path of least resistance.

@Oberon: I don't believe in renewable energy. There is no such thing. Any source of energy requires just as much energy to create as it generates. (To test: Get a plumb bob, hold string in one hand and and pull the weight to the 3 O'clock position with the other, release weight and it will never exceeded the 3/9 O'clock position) This "Renewable" energy is just feeding off of long term decay of a system. The sun will die and Solar will stop working, the Earth will stop spinning and the winds and tides will stop (no turbines), Uranium will decay to lead and nuclear will stop working. Eventuality all heat will die from the universe and all that's left will be the cockroaches.

Unless you are tapping Zero Point energy and that's not even a certainty.
