What this project is about.

The Sternwheeler Ruby is a merging of two fairly different concepts that are extremely important to me. Renewable Energy and Messing about on boats.

We are located in Corvallis, Oregon just a few blocks from the Willamette river which flows south to north through the lush and beautiful Willamette valley.

Ruby is designed to recharge her own battery bank overnight ( winding up the rubber band so to speak) . When end tied at a dock or anchored out in the current the paddlewheel will slowly turn transforming the propulsion motor into a generator. Ruby's system is optimized for propulsion so I don't expect stellar electric generation but it should be something. Obviously a system optimized for electricity generation would perform much better.

In essence Ruby is a proof of concept for a surface mounted water powered generator. Not a new concept, decidedly low tech, but highly practical particularly for the Pacific Northwest. Most importantly it is the most environmentally benign method of hydro electric.

This concept can be designed to supply a couple kilowatts for remote applications, all the way up to a megawatt for municipal applications, and unlike solar or wind this is steady electric power 24/7/365. Rainy days...bring it on!

P.S. Ruby was named after my Grandmother whom I lived with every summer when I was growing up. I helped my Grandfather and Grandmother build a log cabin at their property high up in the Santa Cruz Mountains, CA. They taught me the "no bull shit" way of approaching life.
