Algae powered lamp that absorbs CO2

Algae powered lamp that absorbs CO2

(2:07) Biochemist Pierre Calleja has invented a light powered by algae that absorb CO2 from the air at the rate of one ton per year - that's equivalent to what a tree absorbs over its entire lifetime!

What happens if there isn't enough CO2 available for a period of time. Does the algae die and needs to be replaced? Do you need to feed it anything else or just CO2? How much maintenance is required for example, do you need to clean it out, etc.

The lights are not powered by algae, they are normal lights (actually with a high UV output) that give the algae the light they need to absorb CO2. The merit of this idea is that, since we need street lights anyway, we might as well use these algae to absorb CO2 at the same time. Problems: 1) the CO2 doesn't disappear, it's used to create new algae which will need to be thrown away sometime and then will decompose into methane (worse than CO2) 2) These lights will use more electricity than normal lamps, and 3) the lights will all be green.

Latest comment: I think the point is more about removing the CO2 from the atmosphere than generating useful street lighting. If every home/business had one in the garden or wherever it might make an impact. Dead Algae could be sent for processing and the methane could be collected and used for other purposes.
