Then the problem becomes transmission.


Whether the storage mechanism is a battery or a capacitor, it's still DC and that means the line losses will be huge.


Convert DC to AC and you have huge losses before transmission.


Personally, I would suggest they build one giant Tesla coil in the Hollywood Hills...kill two birds with one stone.

That would be so cool. I hate having to use the wall switch to turn on my fluorescent lights!

The battery banks required to supply this amount energy are going to be huge and pose an environmental risk, plus they will have a life span of around 5 years.
Pipe dreams like these are only practical if money and materials are not considered.

Most people don't know that windmills, solar and battery storage are all DC, or even what DC stands for

An additional $100 part in a car and NOT adding an additional chemical to gasoline during refining is wholly different than the rest of America changing their entire electrical generation portfolio, particularly in states that are heavily invested in LNG and coal. Apples to roof nails comparison.

Also, the catalytic converter and mandating unleaded gasoline were legislative requirements that could be dropped on very few actors. Only automobile manufacturers had to worry about adding the catalytic converter to the car, and only gasoline refineries had to worry about taking tetraethyllead out of gasoline during the refining process. The individual did not have to change their behavior at all.

To have the same PV solar capacity as CA, individuals in the other 49 states would need to invest very serious amounts of money into PV panels on their houses, and do so under threat of legislative force as it makes much less sense in a large portion of the country as it does in the sunny southwest. It's a massive money sink and will require force to implement.

N.G. combined with batteries is cleaner than many of the old ways and in that, it is good.
The plan would be tow charge the batteries during low usage hours and then use the stored energy during peak hours.

This is just like a pumped storage strategy.

yeah, try dropping pure lithium metal into water, the fireworks are interesting. or even just leave pure lithium metal out exposed to the atmosphere, that gets interesting also. lithium metal is an unstable element, which is why it is good at generating electricity. just remember to keep it sealed.

Batteries are easily recycled if there is a will to do so.

yep, and not only that, but the metals are 100% recyclable, as are the chemicals in the batteries

Lithium is a metal and why it conducts electricity. Lithium compounds can be used to store energy. But there is no lithium metal in batteries.
