Synthetic Gasoline Is Created From Biomass and Solar Power.

Instead of burning biomass for the energy needed to create biofuel, Sundrop uses concentrated solar as their energy source to gasify a range of feedstocks including agricultural waste, energy crops, and wood waste. The Sundrop process can produce a range of fuels including gasoline, diesel, and aviation fuel. Many other biofuel processes produce ethanol which has a lower energy density than other fuels, meaning that more of it must be used for an equal amount of work. (Flex-fuel cars get fewer miles per gallon from ethanol than from gasoline, but the ethanol fuel costs less per gallon, and the ethanol is not derived from petroleum.)
