## Abstract

A system for collecting flue gas from a combustion process wherein the flue gas has elevated concentrations of carbon dioxide and converting it into electrical power and useful by-products. Kinetic energy of flue gas is used to power a wind turbine that is coupled to a generator to generate electricity. A scrubber isolates CO2 from other components of the flue gas. The CO2 is converted and stored in carbonic acid solution. The carbonic acid solution is then provided to a galvanic cell that generates electrical power and converts the reactant materials in the cell into useful by-products.

## Claims

### Claim 1
