A Kiwi rural blogger has revealed an ingenious method to generate "free power".
Marty Todd became famous online for his 'Angry Ram' videos, which capture the capers of a hard-charging ram on his rural Nelson property.
But now Mr Todd has revealed an off-the-grid secret, showing how he gets all his power from a home-made water turbine made out of an old washing machine. He's posted the results in a YouTube video.
"I've been living off the grid for a few years now, using a converted water-powered F&P washing machine motor to generate more than enough power to run all the appliances and hot water I use in my house, as well as powering all the tools I use in my workshop," he writes below his video.
"In that time I've saved many thousands of dollars from not having to pay power bills. In this detailed video I'll show you how it's done. I'm told Whirpool Cabrio and Maytag Bravos use the same type of stator motor for those who can't find this model."
By diverting water from a stream on his land, he uses the flow to turn a turbine inside the washing machine. It's low maintenance, only requiring the bearings changed every few years.
A classic example of number-eight wire thinking at work.
