Totally covalently bonded Zirconium-90 as a concept is nothing particularly new and is not of my origination. However, due to the small amount of available literature on the subject, I thought that my prosaic approach to the concept with additional concepts would be illustrative of the great potential of chemical energy. Chemical energy in degenerate matter forms especially in totally covalently bonded heavy elements may enable explosive yields mid-way between the highest performing contemporary chemical fuels and nuclear fissile fuels. Thus, the concepts presented herein need further study for potential technological applications. In cases where the potential chemical energy would match or surpass the nuclear fissile energy of fissile fuels, exotically powerful explosive devices are plausible which can have military and peaceful applications. One application that stands out is compact and extreme invariant mass-specific energy density fuels for powering spacecraft such as relativistic rockets and pellet runway power spacecraft.
