His tests show that wind turbines mounted on a water tower generate 4 times as much power as those just mounted on a mast. This is due to a concentrator effect and other complicated fluid dynamics formulas that we won’t get into. Four turbines generated enough power for about 6 families. These would be great for all those old industrial buildings that have been converted into condos.
