This works (and works well enough) because the atmosphere on Mars is 95% CO2.
On Earth, CO2 concentration is around 425 ppm (parts per million). On Mars, it is ~953,200 ppm!
If we had the same CO2 concentration on Earth, atmospheric carbon dioxide scrubbers and CO2 sequestration solutions would be many orders of magnitude more efficient (and therefore more feasible - enough to actually clean up the mess we’ve made of things, even). But we’d all be dead.
- hoseja 3y agoThere's actually only about 15 times higher partial pressure of carbon dioxide on Mars because the atmosphere is so much thinner.
- ComputerGuru 3y agoGood point. But a compressor pre-stage is still a lot cheaper and more scalable than actually filtering through that many particles to get at each gram of CO2, no?
