Two Stage Configuration Winterberg Fusion Rocket Could Go 20% of lightspeed
Adam Crowl, crowlspace, points out that with the 6.3% of light speed exhaust velocity from Winterbergs deuterium fusion rocket design means a 120,000 ton starship attached to 12,000,000 tons of deuterium can do a delta-vee of ~0.2 c (20% of lightspeed). This would be using the two stage configuration of the Project Daedelus (which was …
