ABSTRACT:
A continuous cryogenic process for the separation and removal of carbon dioxide from the atmosphere using, in part, the existing cryocooling apparatus that is a component of the inventor's patented high temperature superconducting wind turbine electric generating and energy storage system. The proposed system is contained within a long, large, non-corrosive, open-ended, double-walled tubular-shaped vacuum or conventionally insulated dewar, which is cantilevered in two or more units from the wind turbine's steel tower. The major internal components consist of a large screen grid, a small screen filter, a low-speed electric turbo-style fan and, most importantly, a series of coated frost-free heat exchangers of differentiated design that freeze the carbon dioxide in the moving air into a form of flake-like dry ice which is then captured for potential reuse or underground sequestering.
