// Still in development, not going for a specific technology
// Similar efficiency to H2 fuel cells
// Guessing 75% efficient by HHV
// Methane has a HHV of 55.5 MJ/kg
// Liquid Methane has a density of 0.42561 kg/L
// Therefore, we need 0.0000423346 / 0.75 = 0.0000564461 L/s of Lqd Methane to generate 1 kW
// 3.9899 kg O2 for every kg methane
// Liquid Oxygen has a density of 1.141 kg/L, so 1.4883 L oxygen for every liter methane
// running stoich, we then need 0.0000840087 L/s of Lqd Oxygen to match
// 0.0864864 kg/hr LCH4, 0.345074 kg/hr O2
// this will produce 0.194271 kg/hr H2O and 0.237298 kg/hr CO2
// 0.0000539642 L/s H2O, 0.0337858 L/s CO2
