Currently Used Technology:
Current wind turbines are a refined version of a 1000 year old design, originated when cast iron was a high tech material. These wind turbines suffer from the following problems, challenges, and drawbacks:
Our Multi-Rotor technology neatly solves all of these classic problems in wind turbine design. Our new design, now proven in small models, combines the power of multiple smaller rotors mounted to a single elongate driveshaft, to give the same power as a single larger rotor, with less cost, weight, and complexity. Smaller rotors weigh less for the swept area, and turn faster, thereby dispensing of the need for a gearbox. Our new design is naturally self-aiming, requiring no dedicated apparatus to achieve this, and is generally simpler, having fewer moving parts, requiring less maintenance. We expect to validate this revolutionary California design, using multiple rotors coupled to a single elongate shaft as being able to harvest more wind energy at less cost than current models which use only a single rotor.
Our offshore version can be deployed as a floating installation in water of any depth, making windfarms off the coast of California feasible. It looks like a giant fishing pole supporting rotors at spaced intervals. It tilts with the wind, and bends downwind as well. It conveniently dispenses with the rigid foundation, the gearbox, the yaw bearing, the yaw mechanism, the heavy steel tower, directly driving a generator at relatively high rpm. The generator is at or near surface level. The entire turbine comprises only a single moving part, no slip rings or brushes No crane is needed for deployment or maintenance. These floating turbines can be towed into place. They flex with the action of waves while spinning.
Offshore versions require no rigid foundation, no heavy steel tower, run at high rpm to directly drive a generator that is easily accessible from surface level. Multiple small rotors sweep the same area with less blade mass. These floating offshore units may be towed into position, no crane required, simply tilt over to service.
