While the large scale use of biofuels is pretty hard to support in a world facing food shortages--ethanol in Hawaii could make a good deal of sense. It's easily done on a homestead level as well. A good reflux still will turn 5 gallons of guava mash(14% sugar content?) into about a liter and a half of 94% ethanol. Depending on how one blends it with gasoline it needs to be dehydrated by one trick or another. Most cars will handle 10 to 15 percent ethanol as is, some as much as 30. With a conversion regulator even 80 percent ethanol will run in most modern cars. The conversion kits run about 300 bucks.
It makes a fine cooking fuel as well, and may provide an alternative to gas.
High pectin content fruits produce a higher amount of methanol than grain fermentation processes, and if to be used for purposes "other" than fuel the yield will be slightly less as the "heads" need to be discarded.
