High temperature flue gas from a power generation is cooled and enters MOF containers where CO2 is adsorbed. CO2 is then de-adsorbed with additional high temperature flue gas. CO2 is collected and removed from flue gas. Electricity is generated using the heat differential and collected to power the device. Electronic control system uses sensors and controls valves, pumps, cooling system and MOF gates. ## Claims ### Claim 1 A gas collection device for removing a specified gas and outputting a filtered gas from an input gas comprising: a first enclosed gas-tight chamber with a high temperature gas input, a high temperature gas output, a low temperature gas input, a specified gas output and a filtered gas output;
