SORRY BUT I JUST HAD TO STOP THIS NONSENSE when you got to the wow wee a million tons a year. I am an engineer and I can do math and this stuff is complete BULLSHlT. In 2022 the worlds coal production was 8318 Million tons which produces over 30 Billion tons of CO2 How do we know that? Because for every atom of carbon consumes links up with 2 Oxygen atoms to produce CO2 By Atomic weights C=12, O=16 and CO2=44. 44/12 = 3.667 (3.2/3). WE DON'T NEED SYSTEMS CAPABLE OF BILLIONS (with a 'B') OF TONS As for that $100/ton cost being economical! That is utter nonsense last years 37.4 Billion tons alone would cost $3.74 trillion. WHO'S GOING TO PAY THAT? And for these DAC systems to work they need LOW EMISSION energy. HINKLEY POINT C, the nuclear power station currently being built in Britain will produce 3.2 GW (once its finished circa 2028). It was budgeted at £26 Billion and now expected to cost £33 Billion. How many of those do you think we'd need to build to power these DAC systems and make a dent in the issue? I'm Australian and right now we have a pack of clowns ranting about nuclear power. Using the costs of Hinkley Point C we'd need to spend AU$440 Billion just to replace our coal fired power stations. Since our politicians and bankers (because they are addicted to home loans) want to double our population. So we'd need to at least double that making the cost AU$880 Billion. Plus we'd need a decent big chunk again to power all the electric cars we plan to have and now we are past the AU$ Trillion mark. And then we'd have to double the capacity of the power grid which would at least double that to past the AU$2 Trillion mark. At what point do you think we can then afford to pay for any DAC systems? And before you ask one of the biggest issues facing the entire developed world is the cost of replacing all of our old power stations irrespective of how they are powered. You see the difference between Engineers and all the other science is that WE HAVE TO BE PRACTICAL. What all the non-engineers FORGET is that everything wears out eventually and has to be replaced. The simplest DAC system that costs nothing to run are TREES. Best of all they don't need to be plugged into a power station. While all of us engineers are building the next generation of power stations we need the rest of you to go plant a 1,000 trees each. THAT'S ALL OF YOU ACROSS THE PLANET which totals about 8 Trillion Trees. If we consider that a lot will die but a Trillion or 2 survive then that's a lot of CO2 sucked out of the air and captured in wood fibre. So long as we don't burn any of it or let too much of it rot and produce methane we might have a chance.

Oh yeah. GO LEARN SOME BASIC ECONOMICS That way when the clowns waving business and economic degrees like baseball bats can't smack you stupid and manipulate you like they too many of them do. But be warned when you can make a sound economic argument they get real narky about it. Throw math back at them whenever you can. Its drives them crazy. Since you're a Brit start watching Gary Stevenson. He talk's like Jamie Oliver but is possibly the single smartest Brit I have ever seen and I'm Australian. So admitting theirs a Brit who's smarter than me at anything is almost heretical. But he really is that smart on Economics and he makes it easy like Jamie Oliver makes cooking easy.

@alicianah8352 Fantastic concept now who gets to decide which group we EXTERMINATE??? You are right infinite population growth is simply not possible in a FINITE world. David Suzuki howled that from the worlds rooftops all through the 1990s and no business or political leader wanted to hear a word of it. The most important thing we have to work out is a completely NEW Economic system. Feudalism failed, Socialism failed, Communism failed and now Capitalism is failing. There is one thing that was common to all the failures - rapacious greed and consolidation of absolute power into the hands of a few people. We might not need to downsize so much if we can simply get rid of the few who cause all the problems.
