  1. Actually! Already been done with a train on a hill lol. Lots of variations of the gravity battery. These ones using blocks are a scam. Except the ones using already made holes or something. A water tower would work better, and companies are doing that. The thing is there are so many companies working on energy storage as it is the future. So many technologies vying for it, and there are many chemical or thermal batteries that work better for cheaper. Redox for instance looks great. It has to be cheap and scalable. So a liquid chemical battery is great since making a container larger is easier than building a bigger tower. Since a container benefits from square cubed adding one foot equals way more volume. I'm all for renewables. Just not with this when there are better solutions. Redox tech looks great.

  2.  @grahammukuyu4660  Water storage already works, shut up. I know more than you clearly. Way better than this scam. And everything else I said was true. Why don't you compare other technologies. Or watch videos that break it down why this idea is hot garbage just from a physics prospective.

  3. These systems are scams. Sure they do work. The cost per KW is insane. Why not build a water tower. Dig a hole for water. Use a hole already there. Compress air or some fluid. Hell, advanced fly wheels. All the chemical batteries from redox to lithium. There are so many varieties of storing energy that these energy towers using bricks are ridiculous when you do the calculations, and compare it. Again they work. The cost simply is not there. And you're using outrageously sized towers at 4 kilometers total. Yeah, like communities want these towers sprouting around them. Better have an tourist observation post. Maybe that will help the cost if you charge a fee, lol. I saw a company using sea water in a redox battery. Their projections were high, and I am curious what happened. It has been a year, but these infrastructure projects take time.
