Beaming into Space

HobbySpacer writes "At this week's 1st Int. Symposium on Beamed Energy Propulsion in Huntsville a wide range of laser and microwave propulsion schemes are being presented. The big news so far is the announcement by Gregory Benford of plans for a test of microwave propulsion with the Cosmos Sail, due to fly early next year. The possibilities of using lasers to deflect incoming asteroids & comets are also under discussion."

    Well there's a slight problem with the space elevator idea. That requires you to have a large mass at the end of the cable for a counterbalance, like an asteroid. So using a space station attached to a a space elevator to build a ship capable of bringing an asteroid back to balance the elevator is kind of a chicken and the egg problem =)
