This story (By Lewis Page, although without the trademark heavily-overdone sarcasm) describes new technology for thermal (Coal, nuclear, gas, geothermal, etc) power stations that could increase generator efficiencies by 50%. Correspondingly, Co2/KWh reduces by a third.
Although Idon't have any references, supercritical C02 can also be used to dry clean clothes, de-grease steel and de-caffeinate coffee. Truly useful stuff...
