Check this guy out in New Zealand. He converted an old laundry machine to work as a turbine to supply power to his house... Cool video plenty of ideas here...

Hey guys,

i had to paddle back from our boat run today lol, our batteries apparently didn’t hold a charge like normal for some reason. Got me thinking, does anyone have any suggestions for a water turbine that is powered by the river flow too slow charge a battery? There has to be something out there that does that? 

I was thinking if it's possible to charge the battery while sailing and thud have unbending power?
