Steam condenser coating could save 460 million tons of carbon dioxide annually:: If coal and natural gas power generation were 2% more efficient, then every year, there could be 460 million fewer tons of carbon dioxide released and 2 trillion fewer gallons of water used. A recent innovation to the steam cycle used in fossil fuel power generation could achieve this.
Skepticism is good, but if it would seem they have checked things out.
They also ran some durability tests, that pass my poorly informed laymen’s bar of reasonable. (5K scratches and a different test of about 3 years in open.)
