Well, if one new experimental car, called the Lotus Exige 270E Tri-Fuel, ever catches on, this scenario may not be so far-fetched. The specialized Exige is capable of running on an ethanol fuel made from wine that isn't up to drinking grade, or whey, which is also a byproduct of the cheese or chocolate-making process. It was one of several new cars showcased last week at an eco-rally sponsored in part by the Prince of Wales's environmental initiative, Start, according to the Independent.
Even though wine and cheese may seem like alternative fuels better suited for those with a prince's salary, the concept cars nevertheless represent a growing diversity of choice available to car buyers of the future. Here's another proof that there are other greener alternatives than coal. Imagination is the limit!
