Abstract: A cogless electric generator consisting of a compressed nearly all copper air core stator placed within a surrounding rotor containing a plurality of permanent magnets is described which is particularly suitable for direct-drive integration with small-wind turbines. Such turbines become capable of generating electric energy at very low wind speeds. A particular focus is in reducing maintenance and operational costs of such a device by eliminating magnetic attraction of internal components typical of such generators and by reducing friction on bearings through the use of magnetic levitation. Techniques are employed to reduce eddy currents to increase the efficiency of the generator. Air scoops and air flow considerations combined with convective elements intimately in contact with and extending through the stator, allow heat directly from the stator to be dissipated externally.

Abstract: The invention generally relates to turbines that efficiently process air or fluid flow while producing substantially no vibrational effects. In one embodiment, the invention provides a turbine including a rotatable shaft and three helical blades connected to the rotatable shaft, where each of the blades has a helical twist of about 360°.

Abstract: The invention generally relates to turbines that efficiently process air or fluid flow while producing substantially no vibrational effects. In certain embodiments, the invention provides a turbine including a rotatable shaft, and at least one blade connected to the rotatable shaft, in which the blade includes a helical shape and an angle of about 180° or greater.

Abstract: The invention generally relates to devices and methods for treating a body part using magnets. In certain embodiments, the invention provides a device for treating a body part including a carrier and a plurality of magnets, in which the magnets are configured to correspond with a plurality of acupuncture meridian points upon application of the device to the body part.
