It comes from the engine output. It's discharging an enormous amount of energy that's effectively wasted. If you position the exchanger properly then you can use that energy. Sort of like using a shroud around your car exhaust to heat the cabin.
the engines don't get hot like in a normal rocket; if they did, they'd melt like the silicon block used for testing. Dimitry designed the spin drive so that no part of the ship would be in the line of thrust
I don't really understand where the extra energy comes into the system to charge the astrophage. Some type of perpetual motion ?

as it absorbs the energy wouldnt it also absorb the momentum?
Take a look at how rocket engines are currently cooled.
I think your design would work in principle, like recursive breaking, but I’m not sure it would generate enough to make it worthwhile.
The output of those engines is hotter than the surface of the sun.

Astrophage is a perfect fuel. All its energy is transferred into the IR light protons.
