This video was taken after the water crested and pretty much covered the flume, causing it to rise up and down on the flood waters. Managed to save it by clearing debris from the inlet to flood it and weigh it down. It would have been destroyed if I had not been here. The upside to all this wet ... been running all year and they just passed net metering for under 25KW hydro in NY!
I am a retired electronics engineer, educator, businessman and builder of micro hydro installations for fun and sometimes even profit. This one uses a pump/motor as a turbine/generator using a 200 ft waterfall in our back yard. It is currently producing 15KW. I will be tweaking it to take advantage of greater winter flows.
It's not the product, but the process... I enjoy doing the most with the least. So this renewable energy source cost less than $2 per watt of capacity not counting any labor and engineering.
