Future of aviation up in the air
A leading designer and manufacturer of aircraft parts has warned this week that “there may not be an aviation industry in three to five years time, if we do not find an alternative fuel in large enough quantities”, because it is believed that the global scale of oil use will exceed supply.
If he’s right, it looks as though campaign groups like Plane Stupid can put their feet up now.
The company is now looking to invest in various alternative fuels and has expressed an interest in investing in the “fuel from air” scheme that I wrote about previously – the company’s engineers say that Dave Benton’s figures more than add up. According to the calculations, Benton’s scheme would need 3 kilowatthours to produce 1KWH of fuel. A coal power station needs 4KWH of coal to produce 1KWH energy, and a car engine is even less efficient, working at a 7:1 ratio. So petrol from air starts to make sense. What’s more, they reckon that they can get it down to 2:1.
