Space Sailing: Light exerts pressure.  Electromagnetic radiation has a momentum property that - in space, where there is little else in the way of forces - can be harnessed just like wind with a large and lightweight sail.  A low-mass, high-surface area reflective sail can accelerate a space ship in a cost-effective manner through the use of pressure from sunlight alone.

Space Pirates: not so science fiction now, eh?
