Imagine how good life should have been for us, if the elites, DS, cabal, governments, had not kept inventions, cures, and other things from us.
Nikola Tesla was working on battery powered cars but JP Morgan back in the early 1900s said he didn't want it if there wasn't a meter on it that he could collect money from. Tesla was working on zero point energy but we all know power companies wanted no part of that.
I bet there's a cure for cancer but curing something is not profitable. Just having treatments allows these people to keep us in debt and in need of them for life, for some of us.
I think we all should be sick and fucking tired of the elites. I think we all should pissed off at these people. They have kept so much from us, probably many great things we don't even know about.
These people have made sure progression in technology and society benefits was slow as possible so that they could keep stealing money from us.
There could be lots of jobs lost but there will be better jobs for people to get. If these DS etc people get stopped and we ever could have such as thing as free energy among other things, everyone would be able to live better lives.
Cost of groceries and other products would go down, places like Walmart would begin to lose their stranglehold they have against smaller businesses. It's long overdue that these people be dealt with and all of their endless billions of stolen dollars be taken from them.
I don't have that level of detail, I do recall that these have been replicated in modern times and they work, also you are assuming that they are re-chargeable devices, I can only guess at the original uses.
on a general note, a single terminal battery is a useless device, negative and positive terminals are needed for a battery to function, so the negative terminals must have been accessible plug sealed with bitumen could easily be removed by application of local heat.
