A Call For Humor!

My father was a TV repairman (back when there were such things).
His favorite TV repairman joke (which I have doubtless posted here before someplace).

Guy calls a TV repairman to come fix the TV (house calls!)
TV repairman shows up, turns on the TV, evaluates the problem, kicks the side of the TV and the set begins working properly, and perfectly.
TV repairman gets out his pad, writes up a bill for $50 and hands it to the customer.
"Fifty dollars?!?" yells the customer incredulously. "All you did was kick it."
TV repairman nods sagely. "Yes. But I had to know where to kick it."

Yes, troubleshooting/repair is both art and science.

Hydro and wind not entirely. They're partly coming from earth's rotation and gravity via tides.

Tidal hydropower is definitely not coming from the sun, only a smaller part of it. It's mostly lunar power. :D

I thought that hydro was solar - in that the sun is the major influence on the water cycle, after all it causes the evaporation needed for the precipitation later? As for wind, I thought that it was due to differential heating of land and bodies of water, forming hot and cold bodies of air - hot air rises, cold air rushes to take its place, and wind is formed. I was not aware that Earth's rotation had very much influence.

You're right about tidal hydropower though, I forgot that one :)
