Windmill with rotating sails is a new type of windmill. It has a vertical axle around which three sails spin around.

Re: Windmill with rotating sails

Your description "a vertical axle around which three sails spin around" is a Savonius wind turbine. There have been hundreds of these made since 1922.

So, you need to give us a much better description of it.  Or, provide a link or reference to where you heard of it.  Otherwise, we cannot tell what is new or revolutionary about it.
