Solar Sails are the lightest and most delicate of reflective films. They are enormous, for the way they propel the spacecraft is by actually catching the sun's rays. The light from a star such as the sun actually has a very very small force it can exert. In space there is enough solar light pressure to actually move objects. It is a gradual effect, but it builds up with time. Eventually a spacecraft can get moving pretty fast. There have already been designs of real solar sails that have been built by scientists around the world. In science fiction the Solar Sailer of Count Dooku is probalby the best known craft of this type, followed by the Bajoran Lightship. Solar Sailing is one of the most potent ways of transversing between solar systems! Who knows maybe during our lifetime the first star sailor will depart for the distant solar systems! I can only hope to see this!
