Redeployment of “Wind Powered” Generators

It’s becoming increasingly obvious that wind-powered generation is a practical failure; failing miserably to deliver electricity when needed. This invention makes use of the existing wind-generator structure and infrastructure connection to provide electricity generation when the wind doesn’t.

The invention is to install one or more pulse-jet engine near the tip of each wing in order to rotate the machine and generate electricity when there is no wind, but a demand for electricity. Pulse jet engines are very simple machines with few moving parts and run on a variety of fuels.

As wind strength drops, the normal wing action is feathered and fuel supply to the engines opened along with an ignition source. The flow of air through the engine is sufficient to start the pulse-jet engine.

Many wind generators already have access to a source of combustible fuel; usually gas, which is used to keep the mechanical equipment (generator, hydraulic pumps, gearboxes and control gear)  inside the nacelle from freezing.  There is also the ability to drive the rotor using grid power; necessary to prevent bearings and shafts from being damaged when there is no wind to turn the machine.

Some may argue that this is a hare-brained, ill-conceived invention. But what of the wind generators by themselves?

3D Virtual Viewer

A device with an optical display device which can determine its position in space while being moved, can change its optical output characteristic as defined by image data.

One simple implementation consists of an LCD display attached to a multi-axis inertial sensor and a storage device holding image data. As the operator moves the display device through space, the display changes so that a small viewport, corresponding to a part of the full view is visible to an observer.

Application areas for  such a device exist outside of  entertainment and amusement.

Image data that are virtual can be 3-dimensional schematics and/or digital scanned images not visible to the naked eye.  The virtual viewer is then useful tool for e.g. identifying equipment during physical maintenance by following a schematic in 3 dimensions simply by directing and moving the viewer through the space in which the equipment has been installed.

Photographic Genius – Image capture

… or not.

Photographers have long been concerned with capturing what the eye can see.

Seeing things involves much more than just the optics of the eye, but the cognitive and motor functions of the brain. So a major limitation of photography is that the eye doesn’t see everything in the picture. The eye sees only the part of the picture (perspective) on which attention is focused and adjusts the eye dynamically to optimise the visual information. Continue reading
