"This giant bubble on the island of Sardinia holds 2,000 tonnes of carbon dioxide. But the gas wasn’t captured from factory emissions, nor was it pulled from the air. It came from a gas supplier.... "The facility compresses and expands CO2 daily in its closed system, turning a turbine that generates 200 megawatt-hours of electricity, or 20 MW over 10 hours."

Nuclear, in the 1970s. We should have had molten salt reactors worldwide by the 1990s, but the US just sat on the tech, because of permit issues. If I could, I would take all the research that was done on MSRs by the end of the 1970s to then Captain Rickover in 1950.
