Boing Boing listed this article about an engine called The QDrive - which is a "radiation pressure imbalance" drive for space travel.
Over at Cannae LLC in Pennsylvania,they describe the QDrive as
You know what came to mind first? Remember that old cartoon with Wile E. Coyote and the Road-Runner, where Wile E. puts on skates, ties a water tub to the skates and a outboard engine to his waist with the prop in the tub of water. Pulling the starter string sends him off after the Road-runner. Remember? Even as a child I often wondered first, why the crazy Coyote wasn't dead and second it that rigging could really work! I get that feeling off this Q thing....
I honestly thought I was seeing a new type of electric razor head unit....hah

- a resonating cavity with design features that redirect the radiation pressure exerted in the cavity to create a radiation pressure imbalance on the cavity. This differential in radiation pressure generates an unbalanced force that creates thrust. The cavity is accelerated without use of propellant.
