Water powered Energy Conversion Using Buoyancy

Resumen de: US20260286926A1

0000 A fluid-based apparatus that converts buoyancy to mechanical energy with a vertically extending tube filled with water housing an interior water filled cylinder. Motion of the cylinder through the tube along the y-axis moves a cord correspondingly, thus turning the pulleys and associated gears. Beneath the tube is a lower chamber filled with air. When the cylinder is at the bottom of the tube, the air of the lower chamber is released into the cylinder, causing the cylinder to increase in buoyancy and rise. Water that displaces the air in the lower chamber is pumped back into the main tube, and air once again occupies the lower chamber. Upon reaching the top of the tube, an air-tight seal of the cylinder is broken and the cylinder sinks towards the lower chamber. Once the cylinder reaches the bottom of the tube, the cycle of air/water displacement and water pumping recommences.

Resumen de: WO2026190814A1

A multifunctional coastal protection and renewable energy system (100) designed to mitigate coastal erosion while simultaneously generating renewable energy from sea waves (7), winds, and solar power. The system (100) consists of a strategically positioned reservoir (3) near the wave- breaking zone, captures and dissipates incoming wave energy before it reaches the shore, significally reducing erosion. Integrated energy conversion units (6, 1, 2,) harness kinetic energy from waves, wind, and solar radiation respectively, providing a sustainable renewable power source. The structure of system (100) is mounted on an adjustable framework alongwith the pontoon (11) that allows it to adapt to rising sea level, ensuring long-term effectiveness. This dual-purpose system (100) offers a cost-effective, scalable, and environmentally friendly solution, particularly beneficial for coastal regions and island nations facing erosion and energy challenges.
