WAVE POWER

Wave power is generated by converting energy from ocean waves into electricity, offering a renewable and sustainable energy source. Various technologies exist to capture this energy, including point absorbers, oscillating water columns, and surge flaps. Point absorbers float on the water surface and convert vertical wave motion into electrical energy. Oscillating water columns use trapped air and water movement to drive turbines. Surge flaps pivot with wave motion, generating power through mechanical movement. These methods contribute to reducing reliance on fossil fuels while minimizing environmental impact.

REDI AIRPORT

Air transportation consumes a significant amount of energy, accounting for about 2%-3% of global energy use and contributing to approximately 12% of transportation-related carbon emissions. Aircraft primarily rely on jet fuel, which is derived from fossil fuels, resulting in substantial greenhouse gas emissions. Renewable technologies, such as sustainable aviation fuels (SAFs) and electric propulsion systems, can help reduce this carbon footprint. SAFs, produced from biomass or waste, offer a lower-emission alternative, and electrification of smaller aircraft can further enhance energy efficiency and sustainability in the aviation sector.

SURGE FLAP ARRAY

A wave energy surge flap is a hinged device designed to capture energy from ocean waves. As waves pass, the flaps pivot, converting the mechanical motion into electricity. These flaps can be installed in arrays to increase energy capture and efficiency, with each flap working synergistically to optimize the overall output. Key considerations for optimization include flap size, spacing, angle of incidence, and array configuration to maximize energy extraction while minimizing interference from neighboring flaps. Proper design enhances performance and durability in dynamic marine environments.
