Solar sails!!!
« on: May 05, 2008, 22:25:54 PM »
I was watching TV these days and say a documentary on discovery channel. Scientist have develop a special material extremely light and thin. Actually, it is SO LIGHT that the sun can move it like the air moves the sails of a boat. They plan to make a huge sail with this, that is adapted to a space capsule. This capsule will travel in space using nothing but the sun like a wind!!!! Isn;t this great!

But still i cannot put it in my mind. No matter how thin is something, how come sun light move it?  ::) ??? :-[ :-\ >:( >:(

This could also go to news but i prefer it here as it goes together with a question... Or something.

sun light is made of.... photons. Photons have a mass, tiny tiny mass, but they still have one. Sun light is emitted in small blasts. Imagine for example that you have a source of air that produces tiny blasts of air.

The thing is that light travels with the speed of... ehmmmm light. This makes those tiny photons to produce HUUUGE (for their size of course) amount of impulse and thus, move a solar sail.

Yes maybe, but if it happens and we got outerspace for piracy, our ship may propably be hit by an invisible ultra thin overgamma ray from a giant alien spaceship that may see us over 15.000 light years away... We have no chance.
