Water Drops on Metal Plate Could Lead to Better Power Plants

A recent experiment conducted at Massachusetts Institute of Technology (MIT) has suggested that charged water droplets could be created on a metal plate.

It was found that water drops create a superhydrophobic surface on a metal plate and carry an electric charge.

The researches conducted in the past had suggested that due to emission of excess energy from a superhydrophopic surface, the water drops does not slide down and rather jump. The action occurs especially when two or more than two water droplets come together.

"We found that when these droplets jump, through analysis of high-speed video, we saw that they repel one another midflight", said Nenad Miljkovic a Post Doc at MIT postdoc. After few experiments, the researchers were sure that water drops carried positive charge when they jumped from the surface.

A press release issued about the finding stated that the water drops carry electric double layers after forming the superhydrophobic surface, and when they jump from the surface, the negative and positive charges get separated.

This surprising finding could further pave the way for enhancing the role of power plants by improving the heat transfer efficiency of condensers with a due care given to the charge being applied on the metal plate.
