Boostbeam proposal

[stevebowers]

So if we can use these to accelerate a 1kg probe to 0.1c, then we could use a thousand of them to send a one tonne probe. A million of them would send a probe massing a thousand tonnes - maybe enough to decelerate into orbit around another star. They don't need to be accelerated in one big mass - the probes could assemble on route, like Legos.
