I'm just going to file this one away for 20 years from now when electricity is 10-100x cheaper than today and indoor/underground farming is the most economical due to pest, density, and environmental concerns. Could you also say this technology will never make sense? That would be very helpful.

Currently ~50% of the cost of residential electricity is due to the grid, not generation - and it probably affects commercial electricity.
