Supercritical steam does not require heavy tankage? -----Original Message----- From: arocket-bounce@xxxxxxxxxxxxx [mailto:arocket-bounce@xxxxxxxxxxxxx] On Behalf Of Monroe L. King Jr. Sent: Wednesday, February 18, 2015 2:47 PM To: arocket@xxxxxxxxxxxxx Subject: [AR] Re: Way OT question: degerate matter thrusters? I think Supercritical steam would be better than air. High pressures require heavy tankage.
