Pico Hydroelectric Generator in 5 gallon bucket developed by Sam Redfield and tested at La Florida in Guatemala. The generator is meant to be a very small, cheap, low impact generator designed to be used with existing gravity fed irrigation, fresh water, or waste water systems.

    Is there a web page with more info on this project? Are the coils implemented with wirewound resistors? clever! :)

  • tim

    Yes, more details on construction would be wonderful!

    A quick google and I found a video of the inventor Sam Redfield explaining it. At least I hope… I have no speakers at ye’ work computer…

    The folks who did are http://www.aidg.org. Couldn’t find much in the way of tech specifics poking around their site (which doesn’t mean it’s not there).

    There are more pics in their Flickr stream.

    Slick design, but you can only get so much energy out of low head-pressure and low mass-flow hydro — I’d love to see the numbers.

    Hey folks,

    Cat Laine from AIDG here. Sam wrote up some more info on the system here on our blog:

    He’s going to try to get me a parts list with some basic specs in the coming week. I’ll post the link here when he does.

    Cheers,

    Cat

    I’ve been trying to get to aidg.org’s website, with not much success. “this account has been suspended.” Doesn’t always mean it has been, but…

    Hope this comes back.
