Silent portable micro-cogen VAWT made from carbon composites.

The design brief was that the installation should be fully portable. It can be erected by two people without the need for special tooling or lifting equipment and is transported on a small boat trailer.

Most of the functionality of the turbine is based around the use of carbon fibre, a material which has added fatigue resistance, with many other vertical turbines having failed through fatigue in similar aluminium structures, according to the company.

Testing has confirmed that, even at high speed and load, the rotor is effectively silent, and attempts to measure the noise of the rotor showed that perceived noise was dominated by the wind and adjacent trees.

1. For those of us, myself included, less up to speed on this subject:

"The turbine currently drives an electrical generator, but would equally support water or hydraulic pumps and heat pumps."

2. Portable wind-farming...?

3. Aw, but the generator is half the fun :-)

They've a nice sub 1000 RPM generator design that's just as important as the blades.

Though personally I wonder why noone seems interested in transverse flux generators for truly low-speed apps.
