Laser-powered nanocrafts headed to Alpha Centauri: QUOTE Breakthrough Starshot is a $100 million research and engineering program aiming to demonstrate proof of concept for a new technology, enabling ultra-light unmanned space flight at 20% of the speed of light; and to lay the foundations for a flyby mission to Alpha Centauri within a generation. Which are the engineering challenges? http://breakthroughinitiatives.org/challenges/3 Yuri Milner twitter feed (official?): https://twitter.com/yurimilner |

If I didn't make a mistake, I got 0.5 v/c for the energy conversion efficiency for a mirror accelerated from 0 to v by a laser beam, neglecting the Doppler shift, hence about 10% for v = 0.2c, which would be pretty good.
