Directory of technologies and resources relating to solar sails, that use the principle of solar wind in space to provide propulsion.
Solar sails (also called light sails or photon sails, especially when they use light sources other than the Sun) are a proposed form of spacecraft propulsion using large membrane mirrors. Radiation pressure is about 1e-5 Pa at Earth radii and decreases by the square of the distance from the light source (e.g. sun), but unlike rockets, solar sails require no reaction mass. Although the thrust is small, it continues as long as the light source shines and the sail is deployed. In theory a lightsail powered by an Earth-based laser can even be used to decelerate the spacecraft as it approaches its destination. [1] (http://en.wikipedia.org/wiki/Solar_sail)

Solar Sail Technologies
- Finnish Electric Solar Sail Nears Implementation (http://science.slashdot.org/article.pl?sid=08/04/23/1741221) - The Finnish Meteorological Institute has produced plans to build an electric solar sail that will circle the Earth, gaining speed to test its acceleration. One possible flagship mission would be a flight out of the solar system to measure the gas, dust, plasma and magnetic field in the undisturbed interstellar space. (Slashdot; Apr. 23, 2008)
