The wind even on a sunny day could be chargeing heat storage systems to be used in the next winter..#windheating http://t.co/lWuhHveT8k
Vertical axis wind turbines (VAWTs) are slightly less efficient than horizontal axis turbines, but the cost of building them is less and the size can easily compensate. What is shown above could be build at a scale of 1:10 or 1:100, the idea would be the same. The underground heat storage container will accumulate heat as the paddle churns water until the water boils and evaporates. Anyone that needs heat can either use the water directly or use a heat exchanger to pipe the heat to their homes.
