The dust devils are doing a remarkable job, but there needs to be a better way. (http://www.spacedaily.com/news/mars-dust-05b.html)

Working with both undergraduate and graduate students in Appalachian's Department of Physics and Astronomy, Clements is designing and testing prototypes of an electromagnetic screen that might successfully remove dust from solar cell panels on Mars Exploration Rovers.

The test screen looks like a small printed circuit board, minus the diodes and transistors. The screen has high-voltage, multiphase electrodes that produce a traveling electric field or "wave" which carries the charged dust particles off the surface.
