The process of creating a petrol equivalent motoring fuel has been on a constant advance for quite some time now. To give an idea of this Sweden, home to Saab and Volvo has over one hundred thousand flexi fuel Saabs. BioEthanol is a fuel made from 15% petrol and rape seed oil. It burns at a higher temperature to petrol but it comes in much cheaper. The saving here is in the cost of the fuel and not in an actual energy demand reduction. The down-side is that the car has to be set up to run on bioEthanol before use. Some campaigners are critical over the use of bioEthanol, a farm grown product, in a world where we have massive food shortages. The last government also removed all incentives for the purchase of cars that run on bio-fuel.
