My calc was for growing corn and converting to ethanol, which
is not the best way to produce energy. We get wrapped up in
the efficiency of photosynthesis without taking into account that
plants have metabolism, and devour much of the starch they
produce. If we produce energy Bradbury style, with photo
cells, we need not live in an enormous corn field. spike
