Not when they have to be portable. A case for storage batteries can be made.

>you can even make one from compressed air.

Was tried with modern materials a decade+ ago. Wasn't feasible.

Dr Lovins isn't talking about EROEI. I'm sure all the lithium we need is in the ocean itself. Yet when things are dispersed too much, it becomes economically infeasible to gather it up.

There 800 trillions worth of gold in the oceans but it's so dispersed, it's not worth gathering it. Dr. Fritz Haber of Haber-Bosch fame tried working that out for the better part of a decade in the 1920s to help pay for Germany's reparations.

New tech may help. It may not. It's not a magical genie that makes absolutely everything possible.

Maxojir is a channel that basically exclusively deals with metals and oil supplies. The description of the video is the summary:

>The math doesn't work out for the Green New Deal; 100% green energy and electric vehicles EVs idea. Resource constraints of Nickel, Lithium, and Rare Earth Neodymium will hinder the EV revolution, and limits to Silver, Tellurium and Vanadium won't allow all clean green power generation nor feasible grid storage batteries. Solar panels, wind turbines, vanadium redox battery and more.

This is a physical reality. We'll get some type of partial transition but not a complete one or even close to it. The resources aren't there.

There are three things needed for a green economy. Batteries for cars, batteries for stationary storage (storing solar), and metals for solar panels. Without all three, we'll have to burn fossil fuels. There isn't enough material for more than about just less 2/3 transition and that's assuming 0 growth, perfect mining, and that the material goes 100% towards this purpose when in reality the material often has other industries that need it so it's divvied up. In reality, we're looking at about 1/3 transition.

Also, lithium prices have skyrocketed already:

Long haul trucks, rest of the world, assuming there’s enough metals for batteries, panels, and cars (lithium got expensive again this year) — that’s super optimistic.

All wormholes suffer from this problem. You are further or closer to the center of gravity wells like the star in the solar system or center of milky way, etc. same thing.

I’m guessing if two points are like on a piece of paper and changing the spacetime so the paper bends and touches at that point - there’s something in that transfer or process that’s not quite so free everything can jump in.

It’s more than that.

>When temperatures fall below freezing, cellphones need to be recharged frequently, and electric cars have shorter driving ranges. This is because their lithium-ion batteries’ anodes get sluggish, holding less charge and draining energy quickly.

Though if I were in Norway, I would put in a kerosene heater, since as you mention, it’s a battery drain.

It’s not clear from story whether it was USPS. If it was amazon, fedex, ups, it doesn’t apply.

Even if it was USPS, the whole no-name thing can make it ambiguous.

If you’re a similar situation, try ordering from Amazon to an amazon hub locker. Many around, often drug stores and other places. Save the embarrassment.
