The Triangle Age by David Aumelas

SPSFC 2023

Earth is adrift. Its mass is spent, the moon ditched, and the sun is not even a memory. Five thousand humans live in its last city, Thule. None know where they started or where they are going, least of all Lowell. Lowell scrubs the pipes beneath Thule. He knows where to push silt and how to break down a beluga carcass. For everything else he listens to Renth. Renth is a foot taller than anyone else in Thule and yet has never fallen in the reservoir, never been locked in a smoker. She knows the pipes matter. She listens to Lowell, and Lowell talks to no one else. He doesn't need Thule, only Renth, height and all, until she pushes him down the deepest hole in the pipes. To return to Thule, he will brave incineration, muskoxen, the vacuum of space and a giant fan. He seeks Renth, her embrace or her death, and to deliver a message he does not understand.

The Flow of Power by David Aumelas

SPSFC 2024

A flywheel stores energy in a spinning cylinder. After eight years of grad school, Margo is ready to give up on making a better one. Maybe she’s not smart enough. Maybe her aging advisor is stuck on his own failures and has tasked her with an unsolvable problem. She doesn’t really care, until she solves it. The revolutionary Crywheel brings fame and wealth, topples global energy challenges, and drags her into scandal when it starts causing blackouts and car accidents. But, surely, cutting all dependence on fossil fuels must be worth a few dead commuters.
