The EPU is a generator that is used as an emergency backup if someone wondered. Fun fact, some mushrooms also contain hydrazine, including champignons. Proper heat treatment gets rid of it.

  Is champignon a specific type of mushroom in english? I thought it was just the word for “mushroom” in french

    It's the French word for mushroom. However it seems some English speaking people (who sell mushrooms or food made with mushrooms) do call "regular mushrooms" by that name. Probably because it sounds cooler, or because they don't know any French.

      Grandparent might be referring to Agaricus bisporus [0]. At least in my and some of the neighboring countries' languages we refer to these as <local transliteration of champignons>. [0] https://en.wikipedia.org/wiki/Agaricus_bisporus https://en.wikipedia.org/wiki/Agaricus_bisporus

    Both are true, it refers to Agaricus Bosporus [1] [1] https://en.m.wikipedia.org/wiki/Agaricus_bisporus https://en.m.wikipedia.org/wiki/Agaricus_bisporus

It's basically a small gas turbine powered by catalytic decomposition of hydrazine (the same highly energetic reaction used in hydrazine monopropellant rockets, but applied differently). (This is one of the oldest ideas in turbine history. The turbopump in the original Nazi V-2 rocket was powered by the catalytic decomposition of hydrogen peroxide. That's not to be confused with the rocket propellants, which were ethanol + liquid oxygen. It's the small-but-powerful pump that pressurizes the propellants flowing into the combustion chamber). edit: (Basically, these are same things as jet engines, except there's only propellant instead of two (fuel + oxidizer). It's simpler).

And there I was thinking the "raw" water hype was the stupidest thing around drinking water I heard of. And then comes "alkalized"...
