The next evolution of the digital playground body heat install involves . Future systems will not just power their own LEDs but will send excess body-heat energy back to a nearby community center or electric bus stop. Imagine a skate park that heats the restroom floors using the warmth of skateboarders.
Human heat flux is ~50-100 W/m², but TEGs are <8% efficient. Hybridize with piezoelectric pads (capture impact energy) under the same play surface. digital playground body heat install
Standard glass or acrylic blocks infrared light. You must use enclosures fitted with germanium or zinc selenide windows to let thermal wavelengths pass through to the camera lens. The next evolution of the digital playground body
