Put your hands above your head and just breath

Depends what your idea of "average" is.

If I were going to make one that was (for example) 8ft in diameter, the steel and fixings would cost me in the region of £300. To have it galvanised afterward would cost about £80 or to paint it with Zinc paint would cost £50. By the time I have added my labour charge (the going rate is around £45 / hour for a welder / fabricator) and my charge for tooling, electrode wire, cutting blades & other overheads such as electricity & gas you would be looking at between £1,200 and £1,500. Then add V.A.T unless you pay by cash... and bear in mind that most companies would probably double my total.

Of course if you want a bigger one it will cost more. A smaller one would obviously cost less.

Alternatively, a wooden one would cost you a small fortune, as it would have to be made from hard-wood, which, like the people with the necessary skills, doesnt come cheap!

If you only want it for decorative purposes then Ive seen cheap ornamental water wheels for sale in various D.I.Y shops and garden centres in the past.

I have no idea where you might buy a functional second hand one.

Alternatively, if you don't want to make one, there is a company called Aintree Woodcraft that produces hand made water wheels for purchase - http://www.aintreewoodcraft.com

Building the foundations can be expensive if the water is deepand the bottom soft. You have to run a cable back to shore. Maintenance and initial assembly is more difficult at sea than on land.

Because the sea provides ample cooling for the steam cycle, and there are no large rivers or lakes available in a small country.

Most of the time wind turbines are erected on land.

Water turbines are normally found in plant rooms of man made dams, in order to generate hydro electricity (water flowing through turbine, at speed to create electricity).

This is a matter of opinion, personally i think they should. I know many people complain about it 'ruining' the scenery but i think they are quite elegant. People also complain about the noise, but shove a nuclear powerplant there instead and they would be twice as annoyed.

wind turbine will be used as prime mover for electric power generator or water pumps

To tell

a) whether the wind is blowing or not

-AND-

b) which way the wind is blowing

Monsoons provided flooding rain, and droughts that cause starvation.

Perpetual motion machines do not exist. There is no machine that will keep on moving by itself without any added power.

Windmills are driven by the wind. When the wind stops blowing, the windmill stops turning.
