Algae to the rescue


Quote by Andre View Post
Sure, but consider some algae growing device in the ocean. I see 28 ppm carbon for seawater, so that would be 28 gram per cubic meter, but when you have converted that to algeae, it's essentially done. So if you want more yield, you'd need to provide carbon in some form.

...
See further down in your reference. The percent CO2 of dissolved gasses in seawater is 15%, versus 0.04% in the atmosphere.

Two things that caught my attention were the optical density of their algae solution, and something he said. In my testing, the algae was taken to about a 1% solution by weight. And it was like thick pea soup. He mentioned a 0.1% solution, which surprised me. But their algae solution looks more like tea than pea soup so they do seem to be operating with a comparitively dilute solution, and I'm wondering why. Running a thinner solution would likely reduce clogging issues and such, and perhaps their process of coaxing the algae out of solution requires a lower density of algae than traditional techniques.

I just heard about these yesterday.

I think I'll make 5 dozen.


Algae Lamp

How to Grow Bioluminescent Algae at Home

Green Light! Algae-Powered Lamp Needs TLC to Provide Light

Ha Ha!

Sometimes the world mimics PF:

This Micro-Algae Lamp Absorbs 150-200 Times More CO2 than a Tree! (Video)
French biochemist and Shamengo pioneer Pierre Calleja has invented this impressive streetlight that is powered by algae which absorbs CO2 from the air. We have featured algae-powered lamps before but this one takes out 1 ton (!) of CO2 per year. This is as much CO2 as as a tree absorbs on average during its entire life.
And then the comments start:

Oh no, where will one ton of CO2 fit in that tiny lamp!? What happens when it's full!? Seriously people? Google photosynthesis, then comment. The CO2 isn't "captured". It can't get "full". It uses the CO2, breaks it down to feed itself, and releases O2, just like every other plant. (headbang)

I love Science.

That is awesome!

I really like the fact that her lab is under her bed.


This young lady is the embodiment of science.

Someone go find her and sign her up for PF! I'll pay for her lifetime membership!
