Lithium is another secret sauce candidate. From your reference, LiH decomposes at 1,000C. The "Mouse" must attain a minimum temperature that reaches at least 1,000C. After the heat pulse of the mouse, then lithium, hydrogen, and LiH dust particles would have been produced at the termination of the "Mouse's" heat pulse.
*Potassium hydride*, KH, is the inorganic compound of potassium and hydride. It is a white solid, although commercial samples appear gray. As a secret sauce, potassium hydride operates at a lower temperature than LiH. KH decomposes at 400C. The "mouse" must only attain a minimum temperature that reaches at least 400C. Rossi said that he tried various chemical combinations of his secret sauce and used the one that worked best. Now that he is using a hydride to provide hydrogen to his system. If you knew the minimum startup temperature of his reactor, you could use that value to deduce the correct hydride based secret sauce that he is now using. The hydrogen release temperature is the major pacing factor now in secret sauce performance.
