Hm, I guess the efficiency part is possibly interesting on Earth too. Could allow for fresh produce in inaccessible areas with limited space and difficult shipping, even if the power was solar collected, given the efficiencies are so much higher than plant photosynthesis. South pole research station, small islands with infrequent shipping, nuclear submarines.

From a land-use perspective, growing this way can be very efficient. With most industrially grown crops you are essentially limited to one "layer" of crops; but here you could stack crops in a warehouse (though similar arguments apply to vertical farms using artificial light).

Other than this could potentially reduce the energy requirement by 75% or more.
