Subway Tunnel Advertising

This is video entertainmenr or advertising that can be viewed by commuters on a subway train while pasilng through a dark tunnel. The effect is similar to driving through an old covered wooden bridge and seeing the landscape through the gaps between the boards.  

The images are streak scanned while looking through the moving train windows.

Single-Volume Magnetic Reconnection Converter (MRC) with Variable β of Plasma based on Thermodynamic Duty Cycle “α- Dynamo – Magnetic Reconnection”

Magnetic reconnection converter (MRC) based on a single-volume plasma (spheromak) with a variable β in the turbulent pumping (charging)/discharging phases of the thermodynamic duty cycle “α-dynamo – magnetic reconnection”. To obtain helpful energy, the proposed MRC uses a cyclic combination of two physical processes:

α-dynamo, generated by controlled turbulence,

3-D’s Multilayered Grey Water Filtration Membrane

Our idea is to develop a multi-layered filtration membrane for purifying, deodorizing, decolorizing, disinfecting the grey water. Administrate UV treatment for photocatalytic degradation and deactivation of hazardous chemicals of the grey water.

The grey water first passes through the polyolefin membrane, then the multi layered membrane that consists of the polyethylene terephthalate (PET), chitosan, polyurethane cyclodextrin.

Closed-Loop Control of Heliostats in Concentrating Solar Power

Heliosync's invention reduces the cost of concentrating solar power (CSP) and improves its efficiency.

In CSP, a multitude of sun-tracking mirrors (heliostats) direct sunlight onto a central receiver at a distance of up to about a kilometer.

Typically, heliostats follow predetermined trajectories in an open loop. In order to reliably hit the receiver, the heliostats then need to be built massively, i.e.,

Programmable Torque Source for Reactive Power Generation

A positive displacement 'radial steam engine' with infinitely variable valve timing. Can theoretically apply 100% torque from 0 RPM up to the choked flow speed of the inlet piping. By utilizing a high speed digital FADEC with anticipatory algorithms, the speed, torque, and power, delivered to a rotating load can maximize thermal to mechanical energy conversion efficiency.

Solar Movie Theater

Rather than wasting sunlight on the roofs of movie theaters, the sun can be used as the light source for theater projectors.

The roof of the theater is fitted with a heliostat inside a cylindrical skylight.

Electrochemical Alternating Current Luminous Power Regulation System for Non-Dimmable LED Luminaires

System Description

The electrochemical regulator uses electrodes with an electrolyte in equilibrium, preventing reduction and oxidation at the electrodes. It operates with alternating current and is capable of varying or regulating the luminous power of LED luminaires that are not originally designed to be dimmable. The system, through its advanced technology,

Electronic Carnot Engine

ECE directly converts heat into electricity with high thermal efficiency.

Different from traditional direct energy with low efficiency, ECE forces thermal electrons cycling through a Carnot cycle with high efficiency.

By using electronic resonant tank, switches and thermionic tube (with thousands of cells array),
