Here's an idea. Put together an e-moped and carry solar panels. As you park it you set up said solar panels to partially charge the battery pack as you work. More expensive, you could solar-ise a hybrid car the same way. It would take its exposure to the sun as you work before you take off at the end of the day. Not perfect, but it would help. Those solar race cars are such that they are used during the day - exactly when cars are parked. Since cars are used for commuting missions instead of a "rayce" it would actually help a bunch.

In the mean time, I welcome the bit with sugar being used as fuel by making it into booze fuel. That'll get companies to use Splenda to sweeten processed food and it'll cut calories. Splenda is 600 times sweeter than sugar and adds no calories as it's inert as far as metabolism. What the government (or a really rich fuck) could do is buy the Splenda patent and make it open-source like Linux. That way, Splenda will replace sugar in the food all but instantly. That'll help cut down on the obesity problem. Where would you want sugar to be used? In your SUV? Or to make you fat? Put those damn calories in the E85 tank!

Fat is another food item that would be better used as diesel than to make people fatter. Trans-fat would be better used to power a jet plane than used in food. Bio- jet fuel, anyone? Where do you want your trans-fat? In your fried chicken, or to push that RJ140 you are riding in? My prefernce is to put it in the tanks of that RJ140 plane.

The problem is that while making low-calorie food would be great in America, lots of people worldwide NEED those calories lest they starve to death. Given biofuel techniques, it is possible for competition in the market for those calories. While Americans can afford to reduce calorie intake as they pilot those cars around, poor people in Africa (and elsewhere) can't afford to take in less calories. They are already starving!
