The future of wind turbines has already arrived! Below are some 3d renderings of the technology that has already come and that's fully available to you today.

The benefits of a vertical axis wind turbine such as the design above over horizontal axis designs include:

• Can be used in urban settings
• Lower profile for use on rooftops more aesthetically pleasing
• May not be subject to the number of regulations of their horizontal counterparts
• No noise
• No vibration
• Can capture wind from any direction
• Nearly maintenance free
• Easily visible to wildlife. When spinning or at rest, they appear as a solid object
• Self regulating spin speeds in high wind events
• Produce energy at lower wind speeds
