An unstable compound of strontium molecules encased in the crystal structure of water. When fed to a Control Tower's force field generator, these clathrates bond with the molecules already in place in the field to create a nigh-invulnerable barrier of energy. A necessary ingredient for Control Towers to go into reinforced mode.
