Direct air capture is a scam. It requires energy that comes from somewhere else. Capturing CO2 requires energy, it’s basic physics/chemistry.
Nothing about it makes sense excpet as an expensive boondoggle and a distraction for correcting the root causes of climate change.

This will only ever make sense when we have carbon neutral energy that is “too cheap to meter.” So, like, nuclear fusion, or solar panels become cheaper than tar roofs. In other words, these systems will make sense after climate change is solved. lol.
That energy can come from somewhere that doesn't produce more carbon than these kinds of machine sequester. Solar, wind, nuclear. Obviously we need to stop burning fossil fuels, but also we need to turn the carbon we've already produced back into a form that won't find its way back into the air.
It can, but it isn’t and it won’t. DAC is a scam and a distraction until fossil fuels are out of the equation. It is a false hope, a glamour, to keep us from addressing the root causes.
