During desalination, salt and bittern (magnesium chloride) remain, which, when exposed to laser light, produces magnesium. Magnesium is also abundant in desert sand. 10 tons of seawater yield 13kg of magnesium, equivalent to a month's electricity for a standard household. By making magnesium batteries a foundation of life, magnesium batteries can be created from seawater worldwide, reducing the risk of depletion, enabling storage and transport, and allowing electricity use even in remote areas with poor conditions.
This desalination device that produces magnesium requires electricity. Therefore, small hydropower plants will be set up in rivers and streams worldwide. The power generated depends on the drop and water flow. In Japan's Itoshirobanba Seiryu power station, one turbine generates 125kW for about 150 households with a 111m drop.
In addition to small hydropower, tidal power from oceans and rivers will also be used. Tidal power provides stable electricity day and night, and its simple structure requires no large facilities.
Adding small to medium-scale wind power generation to these, the power output increases when the wind blows. Various types of wind power generation have been developed, and vertical axis wind turbines can rotate horizontally, allowing them to capture wind from all directions. In Prout Village, the priority is to create small to medium-scale energy facilities distributed across municipalities so that each can manufacture and manage them, making large-scale wind power generation not a top priority.
