1. A powerplant, comprising:
an engine comprising an engine combustor, an engine turbine, an engine exhaust, a flowpath and a fluid delivery system, the flowpath extending out of the engine combustor and through the engine turbine and the engine exhaust, the fluid delivery system including a hydrogen reservoir and an oxygen reservoir, the hydrogen reservoir configured to store fluid hydrogen as liquid hydrogen, the oxygen reservoir configured to store fluid oxygen as liquid oxygen, the fluid delivery system configured to provide the fluid hydrogen and the fluid oxygen for combustion within the engine combustor to produce combustion products within the flowpath, and the engine configured to exhaust the combustion products within the flowpath out of the powerplant and into an environment external to the powerplant through the engine exhaust, wherein the combustion products exhausted out of the powerplant and into the environment comprises at least one of gaseous oxygen (O2) and/or gaseous hydrogen (H2) and wherein the combustion products exhausted out into the environment provide thrust; and
a water recovery system configured to extract water from the combustion products, and the water recovery system configured to provide the water to a component of the powerplant.
