True, but how much energy used in their manufacture, and aren't they made
from a fossil fuel source? As you said it's expensive. I was considering
the cost and wondering if anyone has ever worked out the cost effectiveness
of growing sufficient quantities to feed people adequately through the
winter months.

Actually one would also need to factor in the energy cost of keeping plants
warm in winter since the fiberoptics won't keep up the temperature. Again,
we're talking about a large operation rather than an unused corner in a
basement or elsewhere. Also cloudy climates won't have enough sun to grow
most foods in winter. Sun-tracking servos need to see the sun to work.

The least total energy intensive solution would probably be sun drying in
season.
