Algae lamps that collect 150-200 times more CO2 in a year than trees may possibly light up streets!



Stanford researchers find electrical current stemming from plants

We all remember from high school biology that plants use sunshine and CO2 to generate energy through photosynthesis, right? An outrageous new prototype lamp from designer Mike Thompson actually generates electricity from algae the same way, in the form of lighting that requires a bit of daily maintenance, not unlike a bonsai plant or a pet.

French biochemist Pierre Calleja is now looking at algae as a potential source for helping clean the air of carbon dioxide. He has spent several years developing what looks to be an interesting street lamp that feeds on the vast amount of C02 swirling around in our atmosphere.

1. Yeah, ok, fine and good

But can we eat these things?

Seriously, this is the kind of science that makes progress. Not at all like the monstrous nuke plants that are eating us.

3. Fantastic info. Can you also please post in Environment and Energy?

Thanks for the encouraging info. How in the world did you come across this?

5. Very, very, interesting.

This might not be much of a "silver bullet" but this is just one more technology that could prove helpful in the long run if implemented widely enough.

7. What about temperatures below freezing?

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.

8. There's a smaller version



I still haven't seen any pics of it working in the dark, though.
