How does direct air capture remove CO₂?

Показать описание

Understand how direct air capture (DAC) technology removes CO₂ from the atmosphere.

DAC machines pull in air and use chemical processes to separate and capture CO₂, which is then stored or utilized. This innovative technology is essential in reducing greenhouse gases and combating climate change.

Questions:
1. What energy source is the fan powered by?
2. is this special filter made of sustainable or recyclable material? How often does it need to be replaced?
3. What energy source is used to heat this captured CO2 to 100C?
4. Where is that pumped water from? Is it wasting fresh water or just using any sea/ocean salt water?

Cool story, bro. Now explain how ridiculously much energy it takes to extract how ridiculously little CO2 and how this ever can be scalable or even come close to extracting the levels of emissions we collectively put out there. Oh, and explain the madness of fanning the ridiculous amount of SAME air you just expelled over and over again through those filters only to capture 450ppm of it. Also, what happens when the storage areas are full? We have been generating CO2 from its most condensed form for centuries and it's now dispersed into its most difficult to capture gaseous form. It will take MUCH more energy to take it back out than it has generated in the first place. So where are we going to get that amount of energy, when it has already been shown that all the 'green' energy systems we have built have only been added to the pile of energy we use as a species, which is easy to see because our emissions have only gone up despite all this new green energy.
