I imagine Jim it will be like the small calculators.....Remember when TI first came out with them....Several Hundred Dollars.....Bought on at the local Dollar Store for two bucks last week.....It does more than the originals......And then there was the MOOG synthesizer....a Million Dollar computer project hooked up to a keyboard......Now you can get one with more gizmoes for under $50.......
Anyway the local soybean farmers are happy and thumbing their collective noses (or digets) toward the East several times a day!
..Remember when TI first came out with themI BOUGHT a couple of those for use in engineering classes (it gets so tedious looking up sine, cosine and tan values et al in tables!); I still have the SR-50 (although the batts are gone) that got me through school - so we've not covered any new ground yet in our discussion.
I do hope that you look into the economics of some of the alternaive fuels, such that you gain a better appreciation for real costs (of production and farming of crops destined for fuel use) and market forces (WHAT the market will pay for a given commodity).
I still stand by my earlier statement as well: "I can't believe that anything is cheaper than raw feedstock that is pumped out of the ground ..."
