Engineering360: ""Mechanical trees" capture CO2 in the atmosphere"

Interesting idea. One concern is the volume of CO2 generated--would it flood the present market?

An additional idea--could "high volumn" devices be placed in the stacks of combustion-type generating plants to capture CO2 at the source?

Capturing to make some useful chemical such as methanol would be nice, but capture to sell is not going to be very profitable, since you can collect it so much easier at the source (such as coal power plants) before releasing it into ambient air.

Lots of chemical and industrial processes produce large amounts of CO2 at very high concentrations. Making hydrogen from CH4 is one example.

This is intended as a publicity thing for companies releasing a lot of CO2 to buy "capture credits" to make themselves seem climate neutral.
