The Challenge

Most energy is generated through the burning of fossil fuels, which releases carbon dioxide and other greenhouse gases into the atmosphere. These gases absorb solar energy and keep heat close to the Earth, also known as the greenhouse effect, which has led to global warming. Finding alternative, renewable sources of energy will be essential in the coming years.

Innovation Details

Both AuREUS devices (Borealis Solar Window and Astralis Solar Wall) use the same principles that create the Northern lights: high energy particles are absorbed by luminescent particles that re-emit them as visible light. Certain fruits and vegetables contain similar luminescent particles, and when exposed to UV light, these particles absorb and re-emit visible light due to internal reflectance. PV cells capture the visible light, where it is converted to DC electricity. AuREUS uses discarded food waste to derive the luminescent particles, which are suspended in a resin substrate.

Biomimicry Story

The Northern lights are made when high energy waves (gamma, UV) are degraded to a low energy state (visible light) by luminescent particles in the atmosphere.
