Can We sustain ourselves with petroleum? (pg. 2)

it will all balance out in the worlds free market...
right now oil is probably the cheapest ways to produce energy, but when the supply will start to dwindle and prices start to soar the obvious outcome is that energy will be gotten from cheaper sorces. demand will always want the cheapest source, right now its oil...
actually it may be so far longer then we expected. I got to a University which is #1 in the nation (possibly in the world) for petrolium engineering and you wouldnt belive the projects they have going here. i can say that there is more untapped reserves of oil then one thinks. right now they say that in the Rwanda area in africa lies a big pot of black gold, add to that the ever increasing effeciency of using oil to make energy (example, better and better miles per gallon on cars) will extend the life of oil...
but alas the future will hold great technological advances and we will be able to produce great quantities of energy for cheaper prices. |

| someone who knows something about science explain to me what the whole hydrogen fuel idea is... if it requires the use of water, i think thats the stupidest ing idea ive ever heard of... we dont have enough water right now for agriculture, consumption and the variety of other uses! but maybe im confused about the whole hydrogen thing... every time someone has tried to articulate to me the concept it seemed like scientists wanted to take water and turn it into fuel.... hmmm.. |

I could be totally wrong on this, but I think you could use seawater, which can't be used for agriculture, consumption, etc... and is, uh, fairly abundant. |

| has to be purified, which takes electricity, which we are also short on... de-salinization plants are expensive... they would have to find a new way to take the salt out of the water... but does the hydrogen process really take water... still not sure |

Are you sure it has to be desalinized? I'm not sure why it would be necessary if you're just breaking the water down to get hydrogen. |

| there is a definate distinction between salt water and purified H20... im not positive either about whether or not they could just seperate the salt when the seperate the hydrogen... hopefully someone else can clue us in on this experimental process. |

it's like the reverse of letting electricity pass thru water. it sepperates the water into hydrogen at the cathode and oxygen at the anode.
so if you let oxygen and hydrogen flow around two plates serving as anodes and cathodes, they are chemically atracted to eachother. this creates usuable electricity and the byproducts are heat and water. |

| so water goes in, steam comes out? |

| of course, petroleum jelly makes ur arse slick so u can be banged more easily. |

lol
no, no steam.
it's not a very efficient way anyway. to create pure hydrogen more electricity is required than it will produce. |
