Heat your House with a Water Brake Windmill #Green #GreenEnergy

Via Low-Tech Magazine: Given the right conditions, a mechanical windmill with an oversized brake system is a cheap, effective, and sustainable heating system.

A solar thermal collector converts solar to electricity and supplies renewable thermal energy in a direct and efficient way.

Much less known is that a mechanical windmill can do the same in a windy climate — by oversizing its brake system, a windmill can generate lots of direct heat through friction. A mechanical windmill can also be coupled to a mechanical heat pump, which can be cheaper than using a gas boiler or an electric heat pump driven by a wind turbine.
