One person speaks up, likely the other guy who talked about the canister as a mechanical life-form earlier. He flashed his lights,
"Interesting. We tried something like that earlier, however the power requirements were massive, and we couldn't exactly extract enough [geothermal] energy from the forge-vent at the center of the city. It was only recently found out that we could cause [g͇̣̰̥͈̐̌̊ḯ̥̲ͨ͂b͖͖̫͙͙̣ͥ̑̑́̍̉ͤb̩́e̲̮̥͓ͤ̾̄rͪͩ̃ͥ̂̓i͉͙͍s̩̬h͇̞ͅ] in [g͇̣̰̥͈̐̌̊ḯ̥̲ͨ͂b͖͖̫͙͙̣ͥ̑̑́̍̉ͤb̩́e̲̮̥͓ͤ̾̄rͪͩ̃ͥ̂̓i͉͙͍s̩̬h͇̞ͅ], and that we could extract energy from these processes. Perhaps we should revisit the idea."
The translator had quite a lot of trouble translating the word geothermal, and they couldn't translate the other two words, however they have a pretty good idea since civilizations like this cannot rely on coal and oil burning, and there's only one sort of reactor primitive enough for this civilization to utilize that could power such a suit.
