Abstract

A London-based company have designed and developed a new approach to harnessing a wider spectrum of winds for the production of electricity which is a credible alternative to the wind-turbines currently used. The company seeks a license agreement or partnership and would like to talk to industry in the manufacturing sector.

Details

The technology is a simple mechanical construction which enables the wind turbine to utilise a wide range of wind speeds, whereas the alternator can keep rotating at its optimal speed (50 Hz or 60 HZ).
Propeller and tail are lightweight which enables the post to be erected at higher altitudes without the need for costly supporting gear.
Variable inputs to a wider spectrum of power enables the system to work at low wind speeds from 2m/s and high speeds without any braking system (Furling system).
Footprint of base is also minimised to house the gears, generator, inverter and batteries.
The wind-turbine can be easily attached to a house or on the roof.
Generation of electricity could charge batteries but also be directly fed into the house electricity supply with a proper inverter.

Innovative Aspects:
ADVANTAGES
Simple, cheap, mechanical construction harnessing more of the available energy of motion from wind, tidal waves or slow moving rivers.
Generator now at base enabling ease of access and inspection.
Free of Maintenance.
Top housing can rotate to enable blades to face wind direction.
Noiseless.

INNOVATIONS
The Technology can be easily adapted to fit existing wind-turbines to increase their efficiency and subsequently an existing market is ready for exploitation. This is also the case for slow moving river turbines and tidal waves power devices.
The existing wind turbines produce electricity by turning an alternator with a propeller.
The speed of rotation of the wind turbine is coupled to that of the alternator which is designed to work at a certain speed coupled to the frequency of the network (60Hz in North America and 50Hz elsewhere in the world). For most existing systems, there is a cut-in speed of the wind to start working and a narrow spectrum of allowable rotational speeds. In other words, for high winds the turbine is braking to keep matching the alternator speed.
The technology described here is a simple mechanical idea which solves this problem by enabling the wind turbine to utilise a wide range of wind speeds, whilst the alternator can keep rotating at its optimal speed.
