will oil run out when I Am alive?

Electric ships would be easy enough. Most modern ships these days are diesel-electric, so just replace the diesel bit with fuel cells or even batteries and away you go.
.
Firstly most ships are actually direct coupled 2 stroke diesels running at u to 120rpm.
Also the energy density of heavy fuel oil is huge and the amount carried on a large ship is thousands of tons
We used about 150tons a day and carried enough fuel to run for a month roughly so you would need gigantic battery banks
Then look at the efficiency of a super long stroke diesel and the fact they run on basically a byproduct of oil refining and you will see why the diesel powered ship will be around for a very very long time
Actaully when i say diesel i don't mean they run on diesel as in the nice clean stuff that comes out of the diesel pump they are diesel engines and they run on HFO or number 6 oil according to this http://en.wikipedia.org/wiki/Fuel_oil
The nearest thing you will of seen to it is road tar, it you take a road and melt the tar down a ship engine can run on it.

Data from BP, who despite trumpeting their green credentials a lot don't really give a fk, but would like to keep the oil price high. Presumably pessimistic estimate of projected consumption and current known and available reserves. speedy_thrills said:
If it was an airship wouldn't you just go nuclear?

We need to get all relevant scientists working on controlling nuclear fusion...problem solved.
As Brian Cox said in BBC's Horizon program "can we make a star on earth" we spend more on ringtones than on fusion research.
Unbelievable.........
Edit to add, I realise fusion would probably be never used in a car, but it would generate an endless supply of electricity and save all the oil being used for heating houses/factories etc.

Also an electric airliner is entirely possible once the battery energy storage density nut is cracked, however we may see fuel cell planes in the the interim.
I reckon airships might be making a comeback, there are some pretty cool designs for hybrid airships being tested at the moment. In the longer term, how about wireless electric for cars and aircraft? That would save them lugging all those heavy batteries about. hollydog said:
Running out of fuel is going to effect life massively if they have nothing to replace it with. Be saying this for years the human race would have to take a step back. Travel commuting and just basic logistics would have to be reduced or stopped. Fingers crossed for Hydrogen. I don't think we could grow enough crops for fuel at the moment. We can't grow enough to feed the world.Fringers crossed for a fuel replacement.
Does it really matter though? Personally I think they'll still be burning oil in 2000 years time, but if it runs out in 200 years who cares? Life will adapt. I'm happy to have been around in the era of the internal combustion engine, but future generations may look back at us in pity that we didn't have what they have, what ever that may be.Airships will make a comeback once they can be made of solar cell-containing material with a high-density battery pack for night flying.
There should definitely be a plow of money sent into the fusion research - it's the golden goose of energy production that would solve a lot of problems... When you think how much is put into defence budgets and bailing out banks etc, even a small portion of that kind of funds would go a huge way.

I'm interested to know whatever happened to a petrol fuel cell, that looked amazing.
Small cylinder lined with photovoltaic cells and a highly heat absorbent inner that converted heat to electricity.
It burnt the fuel in a jet and was apparently ridiculously efficient.
More of that please in the interim.
Hydrogen seems unlikely in the near future, it is such a PITA to store on a small scale.
As for air travel I can't see a move to anything other than avgas equivalents, modern high bypass engines aren't too bad.
It wouldn't surprise me to see ground station LASER based power start making an appearance on low level flight though

Not read every post so fogrive me if it has been answered already. does anybody actually know when we will run out? i expect our energy demands to carry on increasing as the years go on.
Nobody knows when the oil will run out because we have no idea how much we will need and no idea how much we have. Best guess at the current price is that we have 30 years' worth, but if the oil price doubles it becomes worthwhile to extract oil that wasn't economically viable previously.Added to that, unless you believe in gods and fairies and stuff, new oil is actually being produced all the time where the conditions are right.

Have you seen this article, listing some recent activity from various people including NASA, MIT and CERN?As Brian Cox said in BBC's Horizon program "can we make a star on earth" we spend more on ringtones than on fusion research.

Page 2 referes to some device I haven't heard of that is supposedly useable on a domestic level, soonish? Mmnn... I wonder!

If we want to replace fossil fuel with other energy sources and we give ourselves 25 years to do it we need to build:
2 1/2 conventional nuclear reactors every week.
1 3gw wind turbine every 3 minutes.
250m2 of solar panelling every second.
4 olympic pools of bacteria for biofuel every second.
All this for the next 25 years, and not allowing for population growth.
This is slightly wrong.2 1/2 conventional nuclear reactors every week.
1 3gw wind turbine every 3 minutes.
250m2 of solar panelling every second.
4 olympic pools of bacteria for biofuel every second.
All this for the next 25 years, and not allowing for population growth.
These were the figures given in 2010 (I think that was when I first saw it) and it did account for population growth, being that the world currently consumes c.18Tw / year and the quote given for population growth would be 30Tw / year by 2035
you're also missing from the list -
25,000 thermal power stations - 3 per day for the next 25 years
1 tidal buoy in the water every 20 mins for the next 25 years
Horizon - how to build a star.
