5G TECHNOLOGY
This is quite interesting. It is, of course, all present technology that has been used for quite a while, but the increased capability of 5G, around which there is so much controversy, makes it interesting.

It gives the probable history of the battery - going back 1,400 years - to the next generation using solid state techniques that are still in the laboratory stage.
This new technology is not pie in the sky, for it is under the wing of a 96 yr old man who made many of today's devices possible with his work.
