Imagine a smart phone, you turn it on and it runs for 50 years and you never have to charge it.

So this tech is real and you will likely hear a LOT about it on Social Media and hear door knobs talking about a cell phone that lasts forever with no charges. The tech is real, the hype isn't.

The initial battery could not get close to running a smart phone an would cost thousands. I know economy of scale right? Hold on there, the cost of MATERIALS to make ONE of these for a smart phone?

$50,010,000, raw materials only. Yes 50 Million. So now you know not to listen to your Aunt Clara when she blathers on about this.
