SPACE FINS II: Swimming to Mars

Astronauts in weightlessness, inside of a large pressurized habitat, can be self-propelled through the cabin air WITHOUT pushing off against any object. A slipper-like variant of swimfins displaces cabin air to push them forward on their own power (CTF 2023 Holmin).

Prototype has flexible plastic core sheet adhered to rubber soles of strap sandle foot-holders,

Laser-generated Anti-icing and Anti-fogging Transparent Materials

The windshields, windows, and covers of aircrafts, cars, vehicles, and cameras must endure harsh environments. Snow and ice buildup pose significant risks in cold weather, while fogging can obscure the pilot’s or driver’s view, compromising safety. Icing and fogging on cameras also impact their operational effectiveness. To address these challenges,
