Power your home
Bev, this is one of those topics that always starts off a slug-fest and ends in the two (or more) camps calling each other everything but ....
Every few months someone has invented a device that breaks through the old technology and enables a vehicle to get 250 mpg, or to generate enough electricity of a house from the waste water from the toilet dropping through the pipe.
Can you generate 2kwh of electricity from 8" of water fall. Absolutely! If you have enough water volume.
The formula is:
Power (in kw) = drop in feet x volume of water (cu ft/second) x efficiency/ 11.8
Our Scottish fellow claims 70% efficiency and 2 kw of electricity.
2 = .66 x volume x .7 / 11.8
volume = (about) 50 cubic feet per second
Zowie, that's a torrent!.
After following several hundred such stories over the years that the following from the article will tend to explain a lot:
"He and Mr Cattley, who live in Kendal in Cumbria, took the results to the Lake District National Park, and secured a £15,000 grant from the organisation's sustainability fund."
