Thanks! Hmm, yeah I was thinking about everything expect how to make it do useful work, but that is probably the common scenario for most of the new alternative generators. I've always thought that the idea of pumping water for gravitational power storage was a good idea, it means that we can use lots of power when we need to, and collect more when we don't.
Also it is some hundred time cheaper than a standard battery bank, they cost a whole lot!

But yeah I'm totally into your idea, recycle everything that can be reused and don't bother buying something we don't really need. So, one way could be (with a little hard labor) starting the construction of a large tank, or dam if you will.
It could have been a large hole in the ground on top of a hill with plastic inside, or it could be a container built with bricks, and if you have a whole lot of bricks just lying around for no use then it doesn't need to be that expensive.
It is simply about finding the project which is the least expensive and most practical, and then I've have always been fascinated with water so I would have liked that method. Some kind of turbine attached to the end should produce some power, that is probably where the investment lies.

But hey, if you want to produce electricity in large quantities then you have to pay something, if you aren't planning on winding everything by yourself


Also, what I wanted to use as containers was these buckets that has a cap on the top, meaning that if we drilled in a hole or two and just screwed tight some rubber it would work airtight. I know because this is exactly what Tommey Lee Reed did, and just think about the difference in surface area between a garden hose and normal bucket! The ratio will be huge!
Bye for now,
