New invention on wind power energy converter

Singapore inventor Lam Teng Choy (Henry) announces new renewable energy technologies:

Wind Power

Inexhaustible huge amount of dynamic wind current is a continuous movement of air generated by uneven heating by the Sun or high and low pressure regions around the globe. Ocean and wind currents often occur together and advantageously both are renewable energy sources.

It is estimated that there is about 72 terawatt (TW) of wind power around the Earth.

Wind energy converter system converts wind energy into electricity using various double acting racks and rake wheel-generator assembly.

Fundamental Mechanical Devices

The two fundamental mechanical devices are the Moveable device - Double acting rack and the Fixed device - Rake wheel-generator assembly.

The moving devices are in the forms of vertical racks, curved racks, horizontal racks, planar circular racks and ring racks; the fixed devices are rake wheel-generator assemblies.

Fundamental Mechanical Action

The moving and fixed devices are operable to convert kinetic energy of both ocean/sea and wind currents into electricity. Each device is made up of a pair of movable parallel racks that are mounted in vertical, curved, horizontal, planar circular and ring formation. Engaged with each set of the racks are one or more wheel-generator sets as fixed assembly.

For example with the double vertical racks, when wind currents are caught by the wind catching cups, the radial arms tower and wave cam rotate; this causes the racks to translate up and down and these in turn rotate the wheel and generator to produce electricity, the rake teeth on the left hand rack turn the wheel in a clockwise direction while the rake teeth on the right hand rack are designed to slip on the pins of the drive wheel.

When the double racks move downward in a return stroke, the rake teeth on the right hand rack engage with the drive wheel and turn the drive wheel continuously in the clockwise direction while the rake teeth on the left hand rack slip on the pins of the drive wheel.

Renewable Energy Converter Configuration

Based on the fundamental working principle and variations of the above fixed and moving devices, many designs of energy converter can be configured:

· Vertical rack Ocean Wave / Wind converter.
· Curved rack Ocean Wave / Wind converter.
· Horizontal rack Ocean Current / Wind converter.
· Planar circular rack Ocean Current / Wind converter.
· Ring rack Flowing Current / Wind converter.
