Yeah, for this idea to work as transportation, you really need lasers at both ends: one to accelerate the ship, and other to decelerate.<p>So it doesn&#x27;t really solve any problems of initial colonization (beyond fly-by surveys), but it could be used for commerce once a colony has already been established.<p>You&#x27;d also probably want the lasers based on the moon: no atmosphere but large enough not to fly off in the opposite direction.
