Jamais Cascio describes a new design for wind power.
Selsam’s new wind turbine system design, partially funded by a grant from the California Energy Commission, is proving able to deliver substantially more power at a given wind speed than equivalent-sized traditional models. The innovation? Multiple rotors on a single turbine unit, set an angle.
The tests have been remarkably positive so far. A single seven-rotor unit was able to generate the equivalent of 6000 watts in winds of 32.5 miles per hour, six times the power generation of a single-rotor turbine of the same size (7′ diameter) in a footprint not significantly larger than that required by a traditional turbine.
