Just a quick plan for a Power Tower. it is a tower that can generate electricity from flowing water, wind and solar panels. It is based on the premise that there is always one of 3 things happening on the planet at any given time: water is flowing, the wind is blowing or the sun is shinning. A land-based tower can also be built that generates electricity from wind and solar only. Please feel free to use this for your own projects.
Please note that each turbine is meant to rotate on its own axis independent of the other. They are not connected to each other. ie: when the wind blows, the wind turbine does not affect the water turbine.
