LOL... and ouch!

Hi Tom

I always thought that Luke Garner's chase of Greenberg and the alien in "World of Ptaavs" was frought with hazards - blasting along at 2.5 gee to Neptune has got to fly through a lot of junk! I think they were doing ~ 0.035 c at turn-over, which would be bad news. Every tiny dust speck would pack a punch - 55 terajoules per kilogram. So a millimetre sand grain (1.6 milligrams) would pack ~ 86 megajoules kinetic energy. Ouch!

Any sensible Belter stuck to 0.5 gee or so. But even 0.1 gee would be fantastic performance for a fusion rocket.
