In 1993‚ Quantum Devices Inc. (QDI) teamed with WCSAR (Wisconsin Center for Space Automation and Robotics)‚ a NASA center for the commercial development of space‚ developed High Emissivity Aluminiferous Light-emitting Substrate technology to provide high-intensity‚ solid-state LED lighting systems for NASA Space Shuttle plant growth experiments. Their goal was to be able to grow plants in space so humans could have longer stays in space shuttles or the International Space Station (ISS). They discovered
