Lights that are good for us all?

We are used to the idea that we should specify lights that have as little environmental impact as possible – and of course use daylight wherever we can to reduce the need for artificial light.

We are used to the idea that we should specify lights that have as little environmental impact as possible – and of course use daylight wherever we can to reduce the need for artificial light. But what about a light that is actually positively good for the environment?

This is what is promised by a biochemist who has designed an algae light, displayed (where else?) on Geek.This light ‘eats CO2’ or at least the algae that it contains do.Apparently it can take its energy from sunlight, and store it in batteries for night time, or extract it from the air, producing oxygen as a waste product.

It’s certainly an intriguing idea. I wonder how many we would need to prevent global warming? I’m not that keen on basking in unflattering green light. and I hope that, before the lamps become ubiquitous, somebody makes them a little prettier. Most biochemists of course are not trained in product design.
