The key question is: “How do you create the market conditions to make this happen?” Myles Allen’s SAFE carbon proposal directly targeted net carbon emissions. His idea would drive a smooth economic transition from what we have now to a mix of bioenergy and direct air capture with underground sequestration.

I found that fossil gasoline with air…[Read more]

Hi Adam

First, I must emphasise that my purpose is not to “design” the future, merely to show the goal is possible. In this case, the goal is to remove two constraints (energy & earth’s climate) on economic development. If someone invents something better that is a bonus.

Also, by the way, carbon-negative crude oil production based on DriveSolar would be capable of driving atmospheric CO2 well below present-day levels. My feeling is that habitat engineers would probably go for sea level stability. Once people adapted to sea level rise through the 21st and part of the 22nd century, why lower the sea level? Based on…[Read more]

Ian solar crude oil production is quite different from biofuel production. My drivesolar process is very similar to the process used by Sunfire in Dresden. Solar to crude oil thermal efficiency looks to be about 10-14%. Hence the very low land area requirement. DriveSolar is based on 30% area coverage (heliostat to total facility area). Annual…[Read more]
