LONDON, Oct. 19, 2012 (Reuters) A small British company has developed a way to create petrol from air and water, technology it hopes may one day contribute to large-scale production of green fuels.

Handy. This could theoretically in time reverse the effect of global warming if large amounts of CO2 from the air and water were "fixed" into the ground.

Here's a better article on the same topic: http://www.gisborneherald.co.nz/opinion/column/?id=29955

I think, that discovery can help since we are experiencing hardship in terms of gas price.

This is nothing new. Many similar articles on alternate energy (using water, corn etc) can be found during the gas crisis of the '70 over 40 years ago. The key is when it will be cost effective. Cheap gas in '90's killed almost all alternative fuel research.

Here is the comment from the article:
Harrison is cagey about his current production cost per litre: at the “proof-of-principle” stage, everything costs a fortune. But as he told The Independent, “You’re in a marketplace where the only way is up for the price of fossil fuel. At some point there will be a crossover where our fuel becomes cheaper.”

It's not a good idea using food/water for alt fuel on a mass scale IMO. It's probably not a good idea to tamper with the air, either. Uncertain side-effects..

But if new alt fuels are cost-efficient, don't harm/kill by their production, great.

The linked article from the gisborne herald (the .nz link) states the petrol would be carbon-neutral ONLY if the electricity used to produce the synth. petrol comes solely from renewable sources. Currently, color me a bit skeptical about this one - for lots of schemes promise a lot but give little or nothing. The thing is, how do you "burn" carbon dioxide in order to make petrol? At this point, we'd do much better to raise the fuel efficiency standards, build denser suburbs and cities, encourage greater mass transportation, and ...heck, I even have more faith in biochar (http://www.youtube.com/results?hl=en&q=biochar&bav=on.2,or.r_gc.r_pw.r_qf.&bpcl=39650382&biw=1525&bih=698&um=1&ie=UTF-8&sa=N&tab=w1) than this air fuel. I want to be wrong about this, mind you, but I don't see how I could be.

The problem I have is with their proposed catalyst, which I have shoddy understanding of. The methane option they're trying in Germany now makes more sense than this, at least initially.
