38 GtCO2 produced by humans, right?
$200 million commercial plant in 2017, which is expected to extract 1 million tonnes per day - the equivalent of taking 100 cars off the road every year. It plans to start selling CO2-based synthetic fuels by 2018.
1m MT = 1,102,311.31 tons.
So we need to scale this effort.
$200,000,000 = 1102311.31
That's probably a very optimistic number put out there for investors but let's just be optimistic.
So assuming, very optimistically, that it will be running year round at 365.25 days a year, that's:
1102311.31 * 365.25 ~ 402619206 removed a year.
39,000,000,000/402619206 ~ 96.85
So we need to build 97 of these to just target what we are releasing, now. That doesn't include scaling costs to meet increasing needs.
The cost of this would be ~$19,373,144,360.
But the damage is already done. We need to not only reclaim what we produce, we need to drastically reclaim what is already out there.
If we want to be fair and bring the rate back to something normal, then we'd need to reclaim extremely quickly.
Let's be fair: probably 200 of these plants would be needed. So we are looking at $40 trillion.
The $100 trillion figure comes from upkeep, maintenance, localization, etc. Total costs to build these plants and maintain them for years.
Likely, that number is much higher than $100 trillion. However, it is a fair cost and easy to digest.
This should be a 10 year project.

Is it worth spending $100 trillion to make this happen? Some people believe the economic costs will realize a huge RoI by the end of the 21st Century. That we should invest the $100 trillion.
