Scientists turn Air into Petrol
And on the BBC. (I recommend the audio on this one)
A team of British scientists claim to have turned fresh air into petrol. A company called Air Fuel Synthesis manufactured five litres of petrol from a small refinery using carbon and water vapour.
Peter Harrison the company's chief exectutive explained that Air Fuel Synthesis "use renewable energy to take carbon dioxide from the air and hydrogen from water to make methanol. The methanol is then converted to petrol".
The Today programme's science correspondent Tom Feilden told the presenter Justin Webb that it is "clever" that the company "used renewable energy to fuel the process".
"The important thing however is the ratio between energy in and energy out" he added. Until you can "market this project at a price that is affordable it is a bit of a pipe dream".
