How is living on yacht compared to a townhouse/condo?

Are they really too small to live(single) comfortably and how fast do they depreciate? A quick seach revealed that a 40 footer cost more or less the same as a condo or small house, but what are the upsides of living on a boat(other than being mobile)?

How do you harness electricity?

I am looking for a detailed answer on how to harness electricity.

The basic concept is you spin something, usually a turbine or something to that extent, and that somehow becomes electricity. There is a gap in my knowledge and I’m trying to figure out how it goes from spinning to electricity.

If you can give me a link to a website that explains this you would be very helpful.
