RE: A Solar Powered Electrical Plant - that could be built right now from parts on Alibaba
This is an important discussion that people around the globe should be having. The power grids on the planet are wasteful, if the energy isn't used it is lost. Any such technology which prevents energy waste during times of low demand and allows for efficient supply during times of peak demand can drastically reduce the load on our worlds power plants! We should be demanding all available technologies be used to achieve a more efficient power grid, and be prepared to continue implementing future tech increasing efficiency and reducing effect on the planet.
As a bonus, and in addition to resteeming for exposure. We are awarding you a small 5 Steem Power deposit as a thank you for creating quality STEM related postings on Steemit. We hope you will continue to educate us all!
To pump water up, there would also be the use of "bélier hydraulique" invented by Joseph-Michel Montgolfier
Https://en.wikipedia.org/wiki/B%C3%A9lier_hydraulique
The "bélier hydraulique" with multiple tanks placed lower than the turbine could bring the water back into the tank at reduced cost.
Actually it doesn't. The bélier hydraulique uses water flow to create a water geyser. It leaves more of the water at a lower level.
One of the essential parts of the water storage tanks is that it reuses all of the water. It cannot have what wikipedia calls the "free flow at waste valve".
In the two tank system, the pump and the turbine will probably never be used at the same time. It is a storage of kinetic energy for future use. In this particular example, to pump water to the top tank between 10am - 3pm, and then use the water, mostly between 3pm and 8pm, with a small trickle all night (however, there are many other power plants that NEED to supply electricity at night.)
I will edit my post to make it more clear sometime soon.
Thank you.
