Ian Gilmartin

Ian Gilmartin is a British inventor from Kendal in the United Kingdom. In 2006 he invented a mini-waterwheel that generates electricity. The prototype produces 1-2 kW.
The off-the-shelf low-head micro hydro waterwheel system could generate a supply of electricity from a water fall as little as 8 in (20 cm).
Gilmartin is an electrician, but does not own a television and has never lived in a house with electricity.
