It is the kind of garage where a stranger walking in will see chaos; but among the gas barrels and fixtures, tubs of grease and auto parts, everything is exactly in its place. The recycled restaurant grease goes through a t-shirt filter into one drum, then it’s pumped into another and heated, and so on. Everyone’s worried about the viability of ethanol and other biofuels once highly populated countries like the U.S. start using them on a large scale. The question is, is the large scale the answer? Almost every sustainable technology that has been developed to provide energy— like solar panels, wind turbines, and ethanol— works, here and now, on a small scale. It is easier to switch energy sources for one home at a time, and individuals can tailor energy production to meet their particular needs. Just imagine how good it would feel to be producing most or all of your own energy! Also, I imagine that it would be a lot like raising your own food— once you can see first-hand how much work goes into energy production and what can go wrong, you are much less likely to take it for granted and more likely to conserve. I don’t think that anything that’s in massive-scale production is sustainable, regardless of the technology or science behind it. Perhaps we can learn from this guy, making fuel for his own car, in his own garage, surrounded by huge oil barrels and creating glycerine as a by-product that he can refine into soap.
