As a sidenote, Thailand is more "green" in some ways than first world countries. For instance, they sell B5 diesel here at major gas station chains - B5 is 5% biodiesel. And Hi-octane gasoline (95) is all but gone around these parts, supplanted by its E20 (20% methanol) equivalent. Whether this is truly better for the planet in the long run or not is up for debate. It sure isn't better for some older cars!
I met a fellow who has made a small-scale biodiesel production facility in his garage; this is an area I am interested in.
I also want to try building a solar chicken barbecue array - as cheaply as possible. Maybe I'll attempt an Archimedes' death ray out of bits of broken mirror.
