I'm all for people not useing gas (walking, riding a bike, hang gliding) but it's simply not possible to make a gas log for a vehicle that doesn't use gas! I would there for classify it as a relitive of spam, and it should be removed.
it would be nice if there were a "non gas" area, but it's difficult to find accurite ways to calculate the leg power to gas conversion, unless you figure out how much gas it took to grow and transport your food as well, but that is not really my point, a bike shouldn't be in the gas car catigory, nor should a motorcycle, there is however a catigory for motorcycles because they do use gas, and I would feel just fine having a moped in that catigory, I would also feel fine having a gas powered bicycle in there.
I have an electric bicycle, and I wouldn't bother making a gas log for it unless I did something like hooked it up to a gas generator, and figured out how many miles per charge I got, and how many charges per gallon I could do, insted of fallowing vauge ideals of how much energy is in a gallon of gas, and how much energy is stored in my battery... that doesn't fallow reality, I figure if you can't personaly proove that only one gallon of gas was used to propel your bike 700 miles, then show us how you did that.
