Cost. The average American family uses 24 metric tons a year (at least as of 2007, but we're ball-parking here) [1]. The article says it's $500 - $600 to extract 1 metric ton of CO2. (24 metric tons * $550/metric ton) / 12 months = $1,110 per month. That's $1,100 for raw CO2. Once you factor in CO2 => fuel, then transport, delivery, etc. your cost is dramatically higher. Suppose scale could help and the entire process were $1,110 per month. For for most of us, that's still much more than we pay each month in electricity + gas. 1. http://blogs.edf.org/climate411/2007/02/20/picturing-a-ton-of-co2/ http://blogs.edf.org/climate411/2007/02/20/picturing-a-ton-o...

The parent comment was about airplanes. The argument was that batteries are too heavy and that airplanes will still need to run on hydrocarbon fuel. And the argument the parent made is: you burn the fuel in the airplane engine and then sequester it later. And my response is: ok, but if you're sequestering carbon anyway, then use carbon you just sequestered instead of burning new carbon. You didn't understand my point.

According to the World Bank, America produced 16.5 tons of CO2 per person in 2014. Germany produced 8.9 tons per person, Britain produced 6.5 tons, France produced 4.6 tons and Switzerland produced 4.3 tons. Can we all agree that 16.5 tons per person is an absurdly large amount of CO2? https://databank.worldbank.org/data/reports.aspx?source=2&series=EN.ATM.CO2E.PC&country= https://databank.worldbank.org/data/reports.aspx?source=2&se...

  Doesn’t help that so many in the US have no realistic choice for transportation beyond an automobile. I’m a 90 minute walk from the nearest bus station, I work from home luckily (and have no license either) but my wife has to drive literally everywhere. We bought a used 2006 Prius now almost four years ago, so we’ve reduced our emissions as much as is feasible for now - but we still use roughly 300 gallons of fuel a year at 40MPG average.
