But that's just it, Eli. We're not doubling the energy. In the fusor's head-on collisions, the relative velocity between the two deuterons is twice their lab-frame velocity V. Period!...no two ways about it. Therefore, the collision dynamics are the same as if we sent one deuteron at 2V towards a stationary deuteron. What is the energy of a deuteron that is moving at twice the velocity of a 20 keV deuteron? Answer: 80 keV.
