Boffins at Rutherford Appleton Laboratory, near Oxford have invented ‘artificial’ petrol, which is twice cheaper than the actual price of gasoline and could run in existing cars, according to manufacturingdigital.com. Motorists could even be able to drive for 300 to 400 miles before needing to fill up. The breakthrough comes as average UK fuel prices have hit a record high. The new hydrogen-based fuel produces no greenhouse gases and could be available in as little as three years. Professor Stephen Bennington, the project’s lead scientist, said: “In some senses, hydrogen is the perfect fuel. It has three times more energy than petrol per unit of weight, and when it burns, it produces nothing but water.
