refined carbon Catalytic type energy generators ( two described ).

[The Plum Gate]

A refined carbon based catalytic generator:

Part of the catalytics category? Made of refined material / metal. Pipe in oxygen, emits CO2, produces electricity via miracle catalysis.( Some random number loosely based in reality: )

Uses:

• 100g/s carbon
• 133.33g/s oxygen

Produces:

• 233.33g/s carbon dioxide
• Heat + electricty ( make something up nice )

A hydrogen + oxygen based generator: part of renewables category. Made of refined material / metal. Pipe in Both Hydrogen and oxygen. Pipe out hot water or emit steam. I guess it would depend on the level of utility it provides.

Uses:

• 10g/s hydrogen
• 160g/s oxygen 

Produces:

• 180g/s steam or hot water
• Heat + electricty ( make something up suitable here, this may be a smaller variant of generator in the sub 400 watt range )

Each has a reserve storage similar to the existing coal and hydrogen generators. Their saving grace - being made of refined materials and, depending on the numbers, no loss of substance. I've certainly botched these numbers somewhere or everywhere - feel free to chime in. Hydrogen is assumed to be H2. I'll revisit the numbers based on the production figures for the existing electrolysis/oxygen+hydrogen producer.
