Will Solar Winds take us to the Stars

"Astronomy is a humbling and character building experience." Carl Sagan

400 years ago Johannus Kepler predicted solar winds were in existence for the simple fact of comet tails being moved through space. He actually was not that far off. There isn't any wind, but there are positively charged ions, which create a wind like effect.

These Solar sails will sure help rocket carry more, because as of now most of what they carry is fuel. The Japanese have tested this out in 2010 and in 2015 the biggest load, an estimate of 13,000 square feet, will go up. The most important thing I believe is that these are recyclable.

There are three things that are needed: a continuous force from the Sun, some large thin mirrors and a launching mechanism.
