The Starwisp uses microwaves if I recall correctly. Make an impossibly huge mesh that's impossibly light and send impossible amounts of radio energy at it (say a good sized SPS worth) and you've got a starwisp. I think Bob Forward's proposal used 10 GW to boost at 115 gravities for a few days. It would then coast at .2 C for twenty years before zipping through Alpha Centauri. -- Josh Hopkins jbh55289@uxa.cso.uiuc.edu Q: How do you tell a novice from an expert. A: A novice hesitates before doing something stupid.
