Editing Grid Storage and the Architecture of the Reservoir (section)

* '''The Geographic Injustice of Pumped Hydro''' — Pumped-Storage Hydropower is vastly superior to lithium batteries in cost, scale, and lifespan (a dam lasts 100 years, a battery lasts 15). But it is a prisoner of geography. To build a gravity battery, you need a massive mountain, two huge valleys, a river, and a government willing to drown the valleys. The United States and Europe have essentially run out of acceptable mountains to flood. Therefore, despite gravity batteries being the best technology, the world is forced to rely on massive, expensive, chemically complex lithium-ion batteries simply because you can place a shipping container of batteries in a flat parking lot anywhere on Earth.
* '''The Iron-Air Battery Revolution''' — Lithium-ion is too expensive to use for storing power for 10 days. The grid needs "Long-Duration Storage." The frontier is the "Iron-Air Battery" (Rust Battery). It uses incredibly cheap, abundant materials: iron pellets, water, and air. To discharge power, the battery exposes the iron to air, causing it to intentionally rust, releasing electrons. To charge the battery, it uses electricity to reverse the rust, turning the iron back to metal. It is incredibly heavy and very slow, making it terrible for a sports car, but absolutely perfect for sitting stationary in a field, providing incredibly cheap, continuous power to a city for two straight weeks during a blizzard.
