Adds a small generator that you can manually charge by cranking it (like rotating normal buildings). You only get one at the start of each map and crafting new ones is expensive. With default settings it takes 15 seconds to fully crank and then provids 20kW of power for 5 minutes. The HCG can also be connected to circuit networks. For example to use it as a manual count-down timer.
Fits well in low-tech modpacks, packs with electrical offshore pumps or similar.
Mod settings can be used to: Make it unmovable, make it uncraftable, make the recipe cheaper or completely customize the power production capabilities.
