The sun provides about 300W/m^2 on average at temperate climates, that's 7.2kwh per day. Wheat takes about 4 months to grow and nuclear power costs 0.77c/kwh.
That's 665.28$/m^2 at wholesale.

- tuatoru 6y agoIn fairness one should point out that using artificial light one could just provide the wavelengths that are optimal for photosynthesis by wheat. But this would probably only halve theoretical costs, and then there are all the losses in the power production chain...
