The two staples of Stellar Empire technology, Hellerium and Plastasteel are made possible by bending the usual laws of chemistry and folding the molecular structures onto themselves. It can be both used actively (to reduce volume), or passively (to make Plastasteel collapse onto itself when hit, then bounce back). This process is mediated by fine-tuned magnetic fields. Now we can design compressed fuels, and even contemplate synthesizing Plastasteel (Refining and Power will be required).
