This thing appears to work on wood chips.  How do you get enough wood chips?  Chop down all the forests?

Here's a suggestion.  You can reflect sunlight from space on to the ground.  This will enable plant growth 24/7.  If you shine sunlight upon a stand of trees, they will grow much faster.  Fast enough to harvest on a regular basis.

Chop down those trees and you could replace them fast enough to make a system like this work.

As for the space part, it would be the simplest system imaginable.  Just a mirror positioned so that it reflects sunlight from space on to the ground.  No moving parts.  Simple construction.
