What can we do with carbon dioxide?

Question

Compress it, heat it, and we turn it into a metal or rock as the carbon cycle intended. You can find that stuff in the pistons of your combustion engine. What else?

Answer 1

Nature is already recycling it with plants. Plants need CO2 just like U need oxygen.  

Answer 2

Put it in your soft drinks to give them some fizz, pump it into greenhouses to increase plant productivity and reduce watering requirements, use it as a propellant in aerosol cans, it can be used in welding, we use it to make dry ice, we use it to put out fires, some people are using it to make plastics and even gasoline.

Answer 3

Get smart and plant a tree to recycle Co2 into O2. Sequestering in any form removes breathable oxygen from the air.

Answer 4

feed it to algae

co2 absorbing concrete

Answer 5

CO2 is not a poisonous gas like everyone is making it out to be.  CO2 is needed for the global food system, it is not a pollutant.  

Answer 6

CO2+CH4=2CO+2H2

Both are combustible gases, reformed, and are used to produce Iron from Iron oxide.

Answer 7

Didn't anybody go to school?  Plant more trees and let nature do the work.  You wanna go green, that's a perfect way to do it.

Pump it into the ocean?  Wouldn't that kill all the fish?  Leave the water unchanged in your goldfish bowl and see what happens as an object lesson cuz that's what will happen in the ocean.

The whole physical world is carbon neutral.  The only way to create more carbon on this planet is to mine it from another celestial body (planet, moon, asteroids, etc.)   Otherwise, you taking carbon out of something that already had carbon in it.

Read up on the photosynthesis cycle and follow where the carbon goes.

Answer 8

Plant more trees and let them do their thing... converting CO2 to O2 - it's call photosynthesis...

Answer 9

Grow more trees and let them breathe it. From what I know it is one of the essential life giving gasses.

Answer 10

While that might be a great solution in Metropolitan areas, in the area that I live in, we have a better solution, we have more trees than car and people combined.

Answer 11

at the moment, there isn't a good answer.

some options are:

--  bury it in the ocean.

--  pump it underground.

--  change it chemically and store it somewhere.

--  planting more trees.



pumping it in the ocean will make the ocean more acidic.  not good for whatever's living there.

pumping it underground is likely to cause something like happened to Denver when they decided to pump their sewage underground, and earth quakes started happening.  when they stopped, so did the earth quakes.

changing it chemically requires serious energy, which is what we're trying to avoid here.

planting trees sounds good, as long as one does not have to decide where to do that.  when you consider the number of trees required, and the land that would be needed, and also balance in the food that will be needed, pretty quickly you come to the point where it really doesn't work.

as i said, thus far, i really haven't seen an option that i like.

btw, it would be good if you picked a best answer.
