	There's a short discussion of plant efficiencies in Pournelle's "A
Step Farther Out".  I loaned my copy out, so I don't have it with me, but as
I recall the figures he used were certainly under 10%, and (I'm pretty sure)
under 5%.  The great thing, though, is that we can probably use genetic
engineering to double plant efficiencies.  Plants also store energy well.
