COATING POWER PLANT CONDENSER SURFACES WITH A LAYER OF GRAPHENE JUST ONE ATOM THICK MAY IMPROVE HEAT TRANSFER.

In a photo courtesy of the researchers, an uncoated copper condenser tube (top left) is shown next to a
similar tube coated with graphene (top right). When exposed to water vapor at 212°F (100°C), the uncoated tube produces an inefficient water film (bottom left) while the coated shows the more desirable dropwise condensation (bottom right).

Most of the world’s electricity-producing power plants whether powered by coal, natural gas or nuclear fission make electricity by generating steam that turns a turbine. That steam then is condensed back to water, and the cycle begins again. But, the condensers that collect the steam are quite inefficient, and improving them could make a big difference in overall power plant efficiency.
