At least the water won't be an issue. I've heard that they occasionally have a windy day or two though...I saw a news item about storing solar power. In Scotland, I think. They were building an elevated reservoir and planned to pump it full of water during the day and drain it out through turbines at night. With such a system you would want to maximize solar output to run those pumps as well as take care of the normal power consumption.how often are clear, sunny days to be had in Scotland? i'm pretty sure the gravity's always turned on, but not so certain about the solar output . . . .
Windy days?!! I have no idea what those are like.
