Many countries are trying to build solar panels, others are trying to build wind farms. There is a cheap way to use both I think.
Water wheels! The sun makes water evaporate, then the wind pushes the clouds accross the Earth's surface, this is wind and sun together.
I think that the sides of rivers could have cylenders that are disguised as logs lining the river banks. There could be holes in the log imitations that allows water to flow into paddles that push a Dynamo around and around. They would be cheaper than solar panels and discreet.
Additionally aquaducts could be hidden on the side of river banks under bridges that channel away water when the water level is too high and use the excess water to generate even more power.
I wish that you could see what I was thinking. You see, there would be millions of these things, the casing is made of stone but looks like timber so people think that logs vertically lining the river bank. These stone logs are hollow and there are many small holes on one side that allows water to flow though and push the paddles that are connected to a Dynamo.
If I was rich, I could build these things and try to convince governments around the world to install them.
Dreams...
Being an ordinary man is being imprisoned by mediocrity.
