This can be modified to larger scales and customized how ever you like.
One of my teachers at Santa Barbara City College is very Eco friendly and suggested to me that I should build something that takes CO2 out of the air. She showed us a couple of designs that were very cool, I personally felt that this one was the cheapest and coolest.
If we use a mini solar panel to power the air pump and factor the carbon produced from the gas it will take to go and get the supplies needed, about 1/2 a gallon of gas (9.5 pounds of CO2) we will still be taking around 14.5 gallons of CO2 out of the air. This is not counting the carbon produced from any of the items we used (Hopefully recycled items). We also had fun creating the object and watching it turn green.
I have always gone on Kickstarter but never started one, so i felt this would be a cool first Kickstarter to try.
1 X 8' 1/4" aquarium airline tubing - PetSmart Top Fin brand or ACE Hardware flexible plastic tubing
1 X 3' 1/8" inch rigid plastic air hose (3/16 outer diameter) - PetSmart Top Fin brand
1 package 6 air stones - PetSmart Top Fin brand (also available individually)
1 x 2L Clear Plastic soft drink or water bottle with screw on top - Recycled
1 x 2L de-chlorinated water for breeder reactor
EDIT #1 (9/17/2014):
I got a comment about adding a solar panel to the design and changing the rewards. This was a great idea so ill add a small solar panel to the design, it will have a socket that the air pump can plug into.
Also I will add a $5 dollar backer reward to the rewards tab that will include designs to build your very own CO2 scrubber. ($50 backer prize will also receive designs)
EDIT #2 (9/19/2014):
I just added 2 new rewards, the first one is a $10 dollar backer option and it gives you plant fertilizer to grow your algae (also includes previous backer option of $5 dollars). The second reward is a $25 dollar backer option and it gives you a solar panel to power you device (also includes previous backer option of $10 dollars).
