Pinwheel Turbine

A pinwheel turbine is a type of windmill that generates 2.5 kilowatts. It's a stationary pinwheel toy with a wooden stick being replaced by a metal rod to create a small amount of electricity and to prevent burning the sails. You can upgrade it into a pinwheel farm to add 10 kilowatts. It can only be unlocked via researching Pinwheel Prestige once you get a soft reset.
