In a recent interview with Ny Teknik (a Swedish magazine), Craig Cassarino of AmpEnergo said an unidentified company in the United States was interested in using the energy to catalyzer to propel space vehicles.
It seems plausible to me. You would need to get a reaction mass up to a sufficient temperature so that the expansion of it can be similar to a "burn". Provided the temperature was high enough, the pressure of the gas could propel a spacecraft.
By the way, good morning. Finally made it to Friday and the weekend. Thank goodness.
