Can an $100 Million Investment Launch Laser-Based Space Travel?
Oh, it's all very fun, I suppose, doing research into pie in the sky stuff that has a rather useless goal. (I haven't seen the explanation as to how a bunch of micro chip ships getting to Alpha Centuri are supposed to send back useful information, anyway.)
But really, isn't there a whole bunch of more useful local space activities as a goal? An off planet repository for Earth life on the nearby Moon, for example? Working out once and for all if there is useful underground water anywhere there? A space based swarm of micro satellites that could work as an adjustable shield for global warming? Lunar based manufacturing and launch via innovative methods (lunar elevator, mass driver?)
(I have my doubts space based solar being beamed to Earth is ever going to be practical on a large scale, so pass on that one.)
But year, why not research space stuff that's more directly useful?
