If you were visiting Earth from some other planet and had to describe its inhabitants upon your return, you might say that the average person eats rice, and grows it as well, usually on a small scale. You’d be accurately describing the habits of over a quarter of the world’s population. Rice has a special story with an exciting chapter now unfolding in the northeast USA among a small but growing group of farmers and growers.
The first step was to decide on an appropriate chassis, or “running gear.” Eventually I chose to go with the real deal, a wooden-wheeled gear with leaf springs rather than pneumatic tires. Wooden wheels last forever with care and are functional and look the part. I bought an antique delivery wagon that had been left outdoors as an ornament. I was able to reuse some of the wheels and wooden parts of the running gear.
The Savonius rotor was originally designed by Finnish inventor Sigurd Savonius in 1922. It is classed as a drag-type device, and is understood to have relatively low efficiency but high reliability. Interest in the Savonius rotor and other types of Vertical-Axis Wind Turbines (VAWTs) became elevated during the oil embargo and resulting energy crisis. Also, during the 60s and 70s, the Savonius was considered as an example of appropriate technology for rural development in the third world due to its low maintenance requirements.
