CoolJelly
The gym that cools itself with your energy
A bio-inspired passive cooling system for commercial gyms that uses human kinetic energy from workout equipment to pump a special chemical fluid through jellyfish-mimetic soft tubes across the ceiling. The fluid undergoes endothermic chemical reactions when exposed to body heat, absorbing thermal energy and providing air conditioning without electricity from the grid.
You walk into a gym on a 95°F day and see these beautiful, glowing jellyfish-like tendrils gently pulsing across the ceiling, alive with the collective energy of everyone working out below. You feel cool air without the drone of AC units, and as more people exercise, the cooling intensifies—the room literally cools itself through human movement.
