Does anyone have any tips about the production of b100 using ethanol from wvo and/or algae? I believe ethanol will be the best bet for me b/c of cost and danger/ regulations, even though it's harder to work with. All the tips will be much much appreciated, especially for the times I don't have pitfalls! On Mar 30, 2011, at 9:52 PM, Dave Hajoglou wrote:
