I am quite sure that there are "energy devices" or rather methods/technologies of which while not actually "free" are FAR more efficient and thus much closer to free than what is currently being used. This has obviously been shut down by global elites because the energy industry is not only very profitable but also one of the easiest and best ways to control people.
As to water the is actually pretty simple to solve if humanity were not so disconnected with nature and the circle of life. Water never disappears, only changes form, so we can't destroy it or loose it. Its always there. Its just about using it properly and of course better technology could improve this as well.
Liked the post, I too agree that blockchain technology has the potential to be revolutionary and we are already seeing some pretty profound results of it!
