Said biodiesel nut never once mentioned sugar cane, soybeans was the frequently suggested crop, your article is talking about ethanol and not biodiesel, and that wasn’t the point anyway.

This biodiesel nut never said "algae", "duckweed", or "synergy with aquaculture"?

Your nut isn't much of a nut.

That’s probably why he lost all of his money in that venture: just not quite nutty enough. No one’s going to jump on board for something as boring as soybeans.

OTOH, snarky or not, you bring up an interesting thought: there are probably millions of people that know (as in practical knowledge) how soybeans are grown, hence enabling millions to call “bullshit”. Had said nutter said “algae”, I would have to have taken his word until I could research further.
