Microalgae street lamps to absorb CO2 -- could this idea be crazy enough to work?

[LongTomH]

We've all heard the story about physicist Nihls Bohr telling a young friend: "We've all agreed that your idea is crazy! We're just discussing whether it is crazy enough!" Is this idea crazy enough to work:

These algae filled streetlamps supposedly absorb CO2 at a rate of 1 ton per year!

1. A few more details would have been awesome.

Are they bio luminescent, or is it just a clear jar with algae in it?

2. Not bio luminescent!

The algae uses light energy from sunlight; during the night it uses light from an electrical light source - possibly fluorescent, possibly LED's.

I think microalgae fuels should get more attention as a substitute for oil and for absorbing CO2:

Edited to add: Algae 'bioreactors' can work very well with artificial lighting:

3. Seems like a good idea

But the light really isn't all that powerful.

Also, how well would the casing hold up to abuse? You know kids are going to be attacking it.

4. Good points

There are some pretty tough plastics available. The polycarbonate plastic used in NASA pressure suit helmets is also used in some cities to protect their streetlights from abuse.

One more challenge would be cleaning the lights and harvesting the algae. That would create jobs for France's unemployed.
