There are doom and gloom predictions that there will not be enough raw materials for building EVs, especially the batteries. Article https://www.nhm.ac.uk/discover/news/2019/june/we-need-more-metals-and-elements-reach-uks-greenhouse-goals.html Pete Hahn The demand for oil will drop as more vehicles become Electric. Hydrogen will be used for heavy transport – rail, ship and probably heavy trucks. There is a constraint on electrifying

From TSLA group – about hydrogen from my blog previous to this one. Nick Carrière Said, “…fundamental flaws with hydrogen vehicles…” Well, first off ‘converting to AC for a motor’ is necessary for battery EVs, too. But the losses are only a few percent either way. Said, “Total energy losses are several times higher…” That

A tutorial about Ambri’s liquid metal batteries “If you want your battery to be dirt cheap, make it out of dirt!” – Donald Sadoway https://youtu.be/2BlyDVb5L3U LMBs are different. Sadoway says that the designers of Lithium-ion Batteries have to guard against thermal rise; The designers of liquid metal batteries have to guard against thermal fall.
This was from a FB comment I made in Sept 2016. Watson Fixer There was nothing false about Edison’s legacy, unless you consider electrocuting elephants false. Many if not most of Edison’s ideas failed to become inventions. But his invention factory was so prolific that the successful inventions were large in number and importance. In

Ten years ago today, the major earthquake hit off the coast of Japan, causing a tsunami that devastated Japan and caused the meltdown of three of the Fukushima Daiichi Power Plant’s reactors.
The US Trade Commission has said that SK has misappropriated 22 of LG’s battery secrets. The US will ban SK from importing for ten years. LG wanted to negotiate a settlement but SK is begging Pres. Biden to veto the decision. This is interesting because there is high demand for batteries for EVs and it’s

This is the kind of setup I would like to have. I would use it to run my heat pump / air conditioner and maybe a few other things like the microwave oven. And it would be used for charging my EV when it’s at home. The two solar PV panels are 800 watts total.

This was developed by the University in Australia. It seems to be two or three separate parts. It takes solar electricity and converts it to hydrogen. The H2 is stored in metal hydride ?cartridges? Then the H2 is made into electricity by fuel cells. It says that it also has a 5 kWh lithium battery

This article gives an idea of how much a Tesla PowerWall will cost. This StorEn company has only a few employees. They are crowdfunding and have not yet sold a flow battery. They’re supposedly in the business of making vanadium redox flow batteries. https://cleantechnica.com/2020/10/05/tesla-megapack-powerpack-powerwall-battery-storage-prices/ https://www.startengine.com https://www.storen.com Update Feb 23 – TSLA was down to $632

I read a lot of criticisms from doom and gloom climate change deniers who say that the wind turbines and solar arrays are polluting the Earth and blah-blah-blah. They have a hypercritical viewpoint of what is needed to get to zero carbon energy. I think this concept never occurred to them. The craftsman needs to
