A new technique developed by MIT researchers provides the first direct views of how drops and bubbles adhere to surfaces — and how they let go. The findings could be applied to engineering industrial surfaces with controlled adhesion in applications ranging from large desalination and power plants to consumer products. Find out more about this research: http://mitne.ws/15sZxsV

The idea of desalination hadn't occurred to me, but is very intriguing.
