This weather vane weighs just 10 kg and can work in very light winds. It is small in size, but as it is so light it could take another walk and then have twice the strength. Made with stainless materials, this weather vane can last forever, as long as a strong storm doesn't come and destroy it. The only drawback that is, moreover, common to all vertical axis weathervanes is their lower rotation compared to horizontal axis turbines.
