When I was in school, during one of the ASME meetings we had a presentation of a device to remove the ice from the wings. The plan was to have a series of these plates on the leading edge of the plane. during normal flight they would be inlayed into the wing and be aerodynamic. If you were in an icing condition you would start a trickle charge a bank of compactors. Then once the charge was built up a series of panels would "pop" pushing the ice off the wing. Then the caps would recharge and a second series of panels would knock more ice off. and so on. Don't know what happened to the project. anything dealing with aviation takes a long time to develop. It has only been 8 years, which is not really that long for a industry with those types of safety standards.
