The Flow of Power (Paperback) (ISBN-13: 9798392425495)

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.
