Skywind Power

Australian Dr. Bryan Roberts has long been convinced that, by application of an appropriate technology, high altitude wind energy can be captured. He set out to prove that long ago, and has demonstrated that Flying Electric Generator (FEG) technology is practical and should work at high altitudes. This is the "Flying Windmills" technology about which you may have read in publications or on the internet.

Helix Wind

The Savonius turbine based design catches wind from all directions creating smooth powerful torque to spin the electric generator. Mounted up to 35 feet high, in winds as low as 10 mph the Helix system creates electricity to power your home or business.

Quiet Revolution VAWT

The qr5 is a vertical axis wind turbine that we have designed specifically for environments close to people and buildings. It is much more appropriate for winds near and around buildings. It is significantly quieter because the blade tip speed is lower.

Selsam wind turbine
Our driveshaft is at an angle from horizontal, with the nose pointing slightly downward so that, with proper spacing, each rotor gets its own wind.  In addition, the forward tilt of the rotors tends to direct the wind downward, pulling more fresh wind through the machine from above. Any slight losses of power from wind shadow effects are more than made up for by the overwhelming combined power of a multiplicity of rotors.

Altaeros Energies High Altitude Wind Turbine

Altaeros Energies is developing a breakthrough airborne wind turbine to produce abundant, low cost, renewable energy. Altaeros uses safe and reliable aerospace technology to lift wind turbines to operate at higher heights where winds are much stronger and more consistent than on the ground. Altaeros turbines are designed for easy mobility and rapid deployment at remote, military, and offshore sites.

JLM Energy

The Wind Array Turbine System (WATS) technology consists of several, diverse, yet inter-related pieces of technology combining the fields of aerodynamics, power electronics and digital control into a seamless range of products. Air Blades were designed using analytical, computational fluid dynamics and empirical techniques.

Saphon Energy

Now this is unique. The Saphon has been developed in Tunisia and is represented by a beautiful website. But the most stunning bit is that this wind turbine is not actually a turbine. Energy is generate through pistons somehow attached to the 'blade'. Developers say that because it is not a turbine it can exceed the Betz Law - the theoretical limit to the efficiency of a bladed wind turbine.

Aerotecture Turbines

The 610V Aeroturbine consists of a helical rotor and airfoils housed within a 6 ft. x 10 ft. steel cage and weighs approximately 450 lbs. with the alternator attached. The 610V is intended for vertical mounting and can be either bolted or ballasted down. Vertical Aeroturbines work well in winds from any direction, and therefore the presence of a dominant wind direction is not critical. The 610V is modular and may be stacked when needing more power.

A wind turbine is using aerodynamic effect to rotate blades and transform wind into mechanical energy, the mechanical energy then transformed into electric power through generator. The modernized wind turbine can achieve power conversion efficiency between 20-40%. Unlike those large commercial wind turbines, small wind turbines have been widely used to provide distributed power for a variety of applications around the world, such as remote homes and telecommunication systems.
