I would strongly urge anyone seeking to increase their use of biodiesel to google for the words : "Deforestation Palm Oil Biodeisel" and also to consider carefully to what extent arable land should be given over to liquid fuel production, in light both of climate destabilization of agriculture & of burgeoning population, beside the soil and aquifer depletion & pollution due to agribusiness biofuel crop production. If you don't do so now, I think you're liable to end up asking how many childrens' lives you're pouring into the fuel tank of your machine. The Cindarella Option, that of Sustainable Forestry for Methanol production, is quite another matter. It involves the widespread re-forestation of non-arable hill lands, for the (necessarily) local production of methanol (CH3OH), which is suitable for ICE engines, Gas Turbines, Stirlings and Fuel Cells (particularly DMFC - Direct Methanol Fuel Cells). Methanol (originally known as Wood Alcohol) was first traded in 1683, has been made from fossil oil & gas since 1920, and offers a key use for "stranded gas" reserves (that are too small or remote to be worth piping out). Thus methanol potentially offers a seamless transition from the best of the fossil fuels (natural gas) to dependence on sustainable forestry. The sheer range of incidental benefits of this commercial justification of sustainable forestry form a clear example of the Permaculture principle of seeking multiple benign yields from any development.
