Edited Quote...
"The main drawback with hydro-electric power plants is that the water can only be used once. This problem has been overcome with the introduction of the <removed hydro-capillary action> SUN power plant."
This idea owes its conception to the edited quote above...
This proposal
is a hydro electric generator with a closed water cycle. As usual the water is raised to the top of the generator by evaporation (powered by the sun).
The system is placed in a hot climatic region, i.e. desert.
Whalla, Jim exclaims and then looks embarrassed... Voilà!
The inspiration
Hydro-Capillary_20Action_20Power_20Plant
The other way to do this --- might not work [madness, Aug 03 2007]

Details could be useful here. |
|
| |
A reverse fridge. Or maybe a solar steam engine. Either way. this has to have been Baked already. |

... which are presumably called 'deserts' because of the lack of water to be found there. |
|
| |
Deserts are also not always hot. And even the ones that are hot are often only hot during the day, during the summer. Desert means dry, not hot. |
|
| |
We already have a closed-loop stirling engine playing with hot day temperatures and cold night temperatures. It involves using a working fluid or gas and pumping it up and down. See link. |
|
| |
Solar energy evaporates the water, but what condenses it? |
|
| |
The system is clearly not closed with regards to heat energy... if heat energy can enter it can also exit. |
|
| |
So at night for example the water will condense... only it will have moved --- hopefully in an upwards direction. |
|
| |
Note this is not a stirling engine. |
