Water-Repellent Coating Reduces Greenhouse Gases

Dec-01-14 A super-repellent coating from the startup DropWise could help make power plants greener by increasing the machinery's suction force.

The coating was developed for use on a power plant's steam condenser, a series of pipes that turns steam to water on contact. This condensation is required to create the suction force needed to turn the turbine. The new, super-repellent coating helps to increase that force by preventing water from building up on the pipe walls and slowing the cooling process.

Researchers have been trying to create similar repellent coatings for years, but were stymied by the lack of methods for depositing them at the correct thickness. The MIT coating was created by a new process in which two gases flow past heated filaments, which cause the gases to form into the appropriate coating.
