Once the structure is loaded it does not absorb any more energy. If a static structure had to dissipate energy continuously to remain standing, where would such energy come from? Why doesn't your house fall down? Where are the batteries? > rocket equation units should have units of Kg/sec, because that is a mass > flow rate. The equation I was talking about: Me=G*(Ms+Mf) * gamma/(Ve *C) where Ve is exhaust Velocity expressed as a fraction of C. Me is Exhaust Mass. Ms is ship's Mass. Mf is Reaction Mass. G is ship's acceleration. gamma is SQRT(1 - Ve^2 It is inconsistent since it has units of mass on the left, units of mass/time on the right.
