soybeans might be the next thing to invest to to become extremly rich.
i seen where a biodeaisl electric engine in california is suggested getting 100 miles to the gallon on biodeisel (and is in a older heavier car)
the engine costs $30,000 (american)
with green technollogy becomeing increasigly more nessecary, the soybean, already on the rise, would become extremly more valuable once this engine becomes cost effective.
something to watch at any rate.
