For an idea of exactly how small the FCC limits maximum transmitter output power (as fed into the antenna) for the band to 1 Watt. I.e. the low numbers in the results are expectations not early previews for much larger numbers in the future.

In practice even high power WiFi APs tend to top out around 300mW. Multiply by free space power loss and the inefficiencies of the system and the total available power is approximately bupkis.

Those tiny solar cells that power cheap calculators are a far more practical solution.
