Etesian Technologies Co. has been formed to manufacture and market a new (patent pending) wind speed sensor (anemometer) that scavenges energy from the wind it is measuring. This novel anemometer provides its own power from a self-contained generator. It transmits data back to its base station up to 200 feet away, eliminating the need for wires, batteries or photovoltaic panels.

The anemometer is based on a conventional three-cup design. The cups are positioned several inches above the body of the anemometer to minimize the aerodynamic influence of the housing. Internal to the anemometer is a generator design, which has zero drag and no magnetic cogging on the cups. This allows the cups to begin turning at the very low wind speeds, less than 2 mph. Also housed in the body of the generator is state-of-the-art electronic circuitry which calculates the wind velocity based upon the rotational speed of the cups, and wirelessly transmits the information in small packets back to the base station.

Etesian Technologies: (413) 548-9854.
