Share this people shouldn't put cost on this
Something like this should be free for all the people and should have been invented a lot before then now, perhaps it was but the goverments as usuall are trying to limit people…

Not the first time I saw something this cool or life changing. It will get patented and vanish like many others 😞 there is a rechargeable battery that runs on salt water and can be recharged by being filled with new salt water.

The patent was bought by one of the major battery companies and then vanished.

I seen a salt water "power" thing at like the kids science store but pretty sure it wasn't even close to the real salt water battery probably runs for a couple minutes, (or like potato batteries)
