In this video we show you a new concept of wind turbine that is capable of producing electricity while stopped, either for climatic or technical reasons, thanks to a secret hidden inside it that can be used to mitigate the increasingly pressing problem of energy storage when we have nowhere to pour the electricity. And I also present you an interesting advance in the design of the blades of boats and aircraft, with a toroid or toroidal shape, which can revolutionize and impact multiple applications thanks to its greater silence and efficiency. Both inventions are superior to what currently exists but... will they have the ability to grow, escape and impact their markets?
