i want Solar sails PPt.........................plaease send it soon.... or guide me how to download

Please send me the ppt on solar sails and also documentation on this seminar topic

The solar sail is a form of propulsion using the radiation pressure generated from sunlight on the large mirror. A useful scene can be sailing boat; Lightening the mirror is like a sailing boat blowing in the air. The high-energy laser beam can be used as an alternative light source, making it possible to use sunlight, which is a concept known as beam. Solar sail crafts provide long-term work life coupled with the possibility of low-cost jobs. Since they have some running parts and do not use any propellant, they can potentially be used multiple times for distribution of payloads.

The solar sail uses an event that has a proven, measured effect on the spacecraft. Solar pressure affects all the spacecraft, whether in the planets or in orbit around the planet or small body. For example, a typical spacecraft on Mars would be thousands of kilometers away from solar pressure, hence the effect of the 1960s intervals must be described from the time of the spacecraft to effect the trajectory planning. Solar pressure also affects the orientation of a craft, a factor that should be included in the spacecraft design.
