Maybe it is just me but I don't see these things being used outside unless you are near the equator.





Maybe you could get stores and office buildings to put them in their front windows for a source of lighting that would stay on even if the power went out. More of a security back up than a primary source of lighting.





The design would need to be changed. I would suggest something more like a clear pipe (similar to a neon sign) that the algae gets pumped through. Then you could have a central tank, or something similar, where the daily maintenance occurs automatically, or semi-automatically.





I like it, I hope it catches on but I don't think it is going to be a street light outside my house unless climate change really takes off.
