The last time I remember discussing this at uni, we came to the conclusion that the easiest source of hydrogen was that which could be cracked from crude oil. Hence, not much benefit whatsoever. ____________________ I must not be a troll...

Hey, i'm all for biofuels, like gasohol etc. Part bioethanol mixed with normal petrol.
Or just pure bio-ethanol! It has a much high octane rating than petrol so hello monumental compression figures! ____________________ My Flickr |

A hydrogen fuel cell is, at best, an alternative way of storing electricity. As Itchy pointed out - you have to use huge amounts of electricity to split water into hydrogen and oxygen in the first place. You then put the two together and ignite them and *bam* you have power. As for energy efficiency, it's no different to charging up a battery or winding up a big spring. The power still has to come from somewhere.
A solar panel takes 10 years of use to generate the power it took to build the thing in the first place. There is not enough oil left in the world to manufacture the plastics required to replace oil power with wind turbines. We're screwed, environmentally. Far as I can see we have two options:
(1) Learn to use a lot less power, soon. Unlikely, because even if we've got the "green" bug, India and China haven't, and half the world's population lives in either India or China.
(2) Sod it. The planet can look after itself. Sooner or later we will all die (probably sooner), but the planet itself will recover fairly quickly, geologically speaking. |

Old Thread Alert!
The last post was made 17 years, 203 days ago. Instead of replying here, would creating a new thread be more useful? |
