Today's Sunday Six comes from Chapter Seven of Rock Killer:
The Kyushu was an old ship. It was roughly bullet shaped, a hundred
meters in diameter and 200 meters long.
About seven years before, she'd been one of the first ships with the
constant acceleration drives. The power
source was a tokamak fusion reactor, cooled by vaporizing lithium. The lithium plasma was used by an MHD
generator to produce electricity that the Masuka drives turned into
thrust. Before the diminutive Dr. Masuka
invented his drive, ships had to get around the solar system via painfully slow
Hohmann "low energy" orbits.
