I really appreciate them putting actial numbers in here! So many places are deliberately vague on numbers. A $100,000 base cost for the entire system is unbelievably cheap! To put that in context, you could offset the entire worlds CO2 emissions for just $35 trillion worth of these! That might sound like a lot, but it's technically achievable, being half the USA federal budget for 10 years. The energy requirements also aren't impossible, about 350TW of power, easily less than a 100km x 100km square of solar panels. (Admittedly, this is several times more expensive than the Terraform installations, but we need power anyway and will be getting more efficient at solar panel manufacture) Interestingly, this also puts an upper bound on a reasonable CO2 tax of $1000/ton or around £1.8 per litre of petrol, so lovers of fossil fuels and flying can still drive on the track or go for a flight on weekends.
