It was seamless!
Doesn't impress me much. Dealing with a cloud transit is child's play compared to weeks of overcast, not to mention just dealing with night. No mention of cost, either. I can accomplish anything if you give me enough money.

Battery systems are probably necessary to buffer up to a couple minutes of erratic power supply / demand, but it's no good for providing hours of power.
