Energy, Power & Propulsion
The BioCatamaran is an innovative and environmentally eco-friendly watercraft designed specifically to blend harmoniously into nature, making it ideal for sustainable tourism, especially within national parks and protected areas such as lakes, glaciers, mountains, and wildlife observation regions. Unlike conventional vessels, it is uniquely engineered to minimize ecological disturbance and noise pollution,
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.
SUPERSONIC AIRCRAFT PROPULSION PROBLEM
A major challenge confronting the development of supersonic passenger aircraft is the need for a propulsion system which can:
meet the current stringent stage 5 noise requirements during takeoff and landing;
operate efficiently at subsonic and supersonic speeds.
THE PROPOSED PROPULSION SYSTEM
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),

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.
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.,
Smart Power Monitor is a microcontroller-based device designed to monitor electricity consumption in real-time, record power usage data, and transmit this information to users via a web or mobile application.
Key Features:
Monitoring of voltage, current, active power, and energy.
Historical data logging.
Notifications when consumption exceeds the set threshold.
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.
Conventional solid polymer electrolytes used in lithium-ion batteries often perform poorly due to structural limitations, particularly poor contact with electrodes, and they fail to prevent the growth of lithium dendrites—needle-like structures that form during charging cycles and can cause short circuits, fires, or explosions.
To address these issues,
