co2 removal

The scrubber will still require energy to drive it, so unless the fan and pump are powered by solar or wind energy, the fuel burnt to generate the electricity it consumes will probably negate any benefits gained. And you'll still need to dispose of the spent NaOH solvent.

hello sparkstation, good reply! Like I said, it was just a thought, I was watching the news and they were talking about the " global warming ". I just think the folks of planet earth should be a little less reckless with all the beautiful things mother earth gives us to exist. Just one thing to remember, around the 1420's, the U.S. did not have 300 million people for a population, not to mention millions of cars driving about, and big industries all adding a little "extra" co2 to the air. So, I think its a bit of a scam, however, there is abit of truth to it. afterall, what will our grandkids be left with? carpe' diem!!

Yes! It is called plants in a greenhouse. You and your cat and your gasfired furnace exhales CO2. Your plant inhale it, and with a bit of sunshine they produce vegetables for you to eat. You exhale CO2, and the cycle repeats. It needs some work and care, but it is known to work. The more work you are willing to put in, the less the actual cash outlay.

Just a few years ago there was a huge glasshouse set up in the Arizona desert just to test exactly such a closed system, which will be needed for long distance NASA flights with people aboard. As a prototype it unearthed plenty of problems, but that it is the nature of things in development. As far as I know, the space station sill uses scrubbers. But longer flights are not feasible with them.
