ive allways wondered if it would be posible to get "free energy" using millions of very small tubes to move water up in elevation and then let it fall back down hydroelectric style. (even if the water could only be raised several inches it would style give energy without any input that i i can think of)

the question is how many tubes would it require and over what surface area? it would probably have the same problem as solar power, you would have to cover 1/3 of the country in tubes to power it.
an interesting idea i heard about was using waves as a power source, just having a giant paddle connected to electrodes, ever wave that hits it pushes it back and creates tremendous force
