Watermelon Juice Makes Great Biofuel 160
Mike writes "Watermelons are more than just a tasty summer snack — researchers at the USDA have determined that the fruit constitutes a promising and economically viable source of biofuel. It turns out that the relatively high concentration of directly fermentable sugars in watermelon juice can be easily converted into ethanol. Rather than grow fields of the fruit for the purpose, the report suggests that farmers capitalize on the 20% of each annual watermelon crop that is left in the field because of surface blemishes or because they are misshapen."

This is all wonderful, us rich people can continue to drive GMC Yukons or whatever, except it has the same problems as using other foodstuffs for fuel. Oh, sure, you can use the 20% bad watermelons for it, but once watermelon->fuel processing capacity exists, market prices will dictate whether the 80% of good melons go to the grocery store or to the melon refinery, and when the global economy bounces back and fuel prices go up, it'll be just one more thing putting pressure on the food supply. Before anyone says "oh, but watermelons can't be a large part of the global food supply," what happens with cash crops is they end up more valuable than food crops (hence the name) and displace them in the fields.
And so this whole thing is barking up the wrong tree - the fuel is alternative, but it sure isn't sustainable, just one more squeeze on substance farmers someplace we don't give a damn about.

They aren't suggesting growing more watermelons, they are suggesting that the watermelons that are presently left in the field to rot could instead be harvested and sent to a distillery.

My family owns and operates a peach orchard in Colorado. I've helped with harvesting the trees and pruning the crop, and I'm reasonably familiar with the entire process. Any kind of surface defect or imperfection results in the fruit being thrown on the ground, or discarded. Our farm is fairly small, and only the truly massive farms can really make money selling fruit at less than grade A standards, because the prices are simply awful. Its just not worth the fuel to ship it at that point.
Most of your grade "B" fruit and veggies comes from grade "A" fruit that sat around too long, and was sold at the lower price rather than thrown out.
