I guess computers doing it for decades and phones basically being all-in-one computers wasn't enough to make this too obvious to patent
Twenty-nine years ago, I read about a breakthrough in battery chemistry that would make the common NiCd battery obsolete: the new chemistry had four times the capacity, could stand ten times as many charge-discharge cycles, and had no memory effect.
In the decade and a half that followed, I read about a number of other miracle energy-storage technologies: hydrogen, methane, methanol, and ethanol fuel cells; sodium, zinc, and lithium battery chemistries, and a number of other breakthroughs. None of them ever seemed to turn into an actual product I could buy, though.
I kept following that chemistry I first read about in 1988, seeing it pop up from time to time in uses such as electric vehicles or laptop batteries, but never in a form I could make use of. And finally, in 2003, I was able to go to a store and buy a set of those NiMH batteries to use in my digital camera.
Nuclear power has ramp-up and ramp-down times measured in hours or days. Because of this, it is strictly a baseload power source, just like coal. For peaking power, you need hydro, natural gas, or storage.
(Solar and wind are strange critters from a load-management perspective. They have the response times needed for peaking power, but not the availability.)
I don't know where you're getting $10 from -- the music Pandora's streamed to me over the years would barely fit on a 128GB SD card, and I can't find those for less than $30.
