Just some thing to not think about! Found this little bit
WHEN WILL OIL AND GAS RUN OUT?
IT'S thought supplies should hold out at least until 2025.
This could be extended to 2040 by conservation measures such as making cars more efficient.
Gas is expected to become scarce between 2025 and 2050.
But high oil prices makes it worthwhile producing from otherwise uneconomical fields.
I remember in 1973 everyone was panicking cos we would be out of fuel by the end of the century!
If govt really cared, they would protect 'portable' fuels like gas, oil and coal supplies. Instead, we close the coal mines, and use gas for
power generation.
Altho nuclear isnt ideal, at least it conserves portable reserves instead of going the cheapest most convenient route of gobbling up domestic gas for
industrial use.

Oil will not run out that quickly guys...do some reasearch!

yeah, it's nonsense. there's oil left for many years yet.
Just did some research...the answer is, its complicated...all previous estimates have proved completely hopeless, we now know of more oil on the
planet than we did in 1950, 4x in fact, and 2x than what we thought we had in 1970! It certainly seems that in our lifetimes we wont run out.
Alternatives are interesting...fuel cells seem the way to go, anyone know anything about them???
Tim
AFAIK, a fuel cell converts hydrogen and oxygen into water and electirc potential, rather than just burning it and making heat. the fuels (H and O)
are made from water, with electrodes. As far as i can see they are just futuristic batteries, unless there is a good source of H and O out there.
IMHO, nuclear plants would be a good way of seperating water, since nuclear power isnt really portableas such.
It's easy to convert a petrol engine to run on ethanol, a renewable energy source. But I suppose some people have moral concerns, a waste of
good booze 
I have read some about fuel cells and they seem a dead end at this time. Most commercially available fuel cells run on hydocarbon based fuels same as cars already do. They also have a much lower energy storage density. 1 Gallon on gas even at 25% eff is still a lots of energy.
Here in Brazil we have alcohol (my 7 will run on it, gives more power) made from sugar cane, it does less mpg but is more than 30% cheaper per
litre....natural (i think its natural) gas conversions on cars is very popular right now too, very cheap, but of course not renewable. Anywhere else
using gas? Needs an enorous tank in the boot.

Biodiesel is one way of keeping the infernal combustion engine firing for as long as vegitation still grows on the planet.
Linky bit
All the waste vegetable oil from your local chippy can be converted at home into biodiesel. I cant find the link in my favourites but google is full
of it.
Found it. another linky bit

I have the patent for an external combustion engine that my grandfather designed years ago - was about 75% efficient as well.

As I stated in another post, I run my Nissan Almera on 100% BioDiesel with no problems.
Engine is smoother due to higher lubricity of fuel and the emmisions have a net CO2 of zero.
I havn't used a forecourt diesel pump for about 2 months now. Very liberating
Cheers
