Glowee

French startup Glowee is rethinking lighting by harnessing bioluminescence -- light produced by living organisms, like jellyfish or fireflies. With lighting accounting for up to 30% of global electricity consumption, Sandra Rey, CEO and founder of Glowee has been looking to nature to inspire how biological lighting systems might help humans use energy better.
