Not a revolution but interesting to know that the trend will continue.
Just another improvement, not a revolution that will change much, certainly not for aircraft.
The packaging is a pretty clever innovation, IMHO, but hardly worthy of the hype.
It's certainly more than just PR. But it's an industry roadmap more than a product announcement. The implications are huge, but few will get it.
Given that Tesla was created with funding confiscated from tax payers, does anyone think that the timing might, in some way, be connected to this? California to Ban Sales of New Gas-Powered Cars Starting in 2035

Peddle, not pedal.
Yes, it was a play on your words, eg; humour, because I haven't a clue what you are on about.

No, it's standard fare around the World now, the USA is late to the party, relatively speaking.

Surely it's obvious to anyone that generating electricity (inefficient and large energy losses) and then storing it (inefficient and large energy losses) is not the way to go. Generating on demand by using a hydrogen fuel cell or some similar technolgy (maybe even one that we do not yet know about) has to be the way to go.


Ignore the sensationalism of the headline (we need something to celebrate in the middle of the Covis crisis) - just concentrate on the content. If I had money to invest I wouldn't be putting it into battery technology. It's very last century (last two actually).

For those of you who truely are interested, start by reviewing the state of the art of hydrogen production, DOE Hydrogen and Fuel Cells Program: 2019 Annual Progress Report - Hydrogen Fuel R&D then move on to storage, distribution, and end use technologies. If your objective is to understand the potential impact on man-made grenhouse gas emissions, be sure to assess the total energy conversion process.

Isn't hydrogen produced from natural gas?
Yes, I know it can be made from water using electricity at poor efficiency. But, that is cost prohibitive.

Musk is using methane for rockets. Not batteries, because methane does work for the task.
Methane (natural gas) or propane or whatever synthetic hydrocarbon you want is a substitute for hydrogen.

Natural gas and propane are not synthetic hydrocarbons.

Well you would get booted out of Greeny/Climate groups quite quickly sprouting factual stuff, lol!

I watched this because it was recommended to me, and I started out completely cynical, and it didn't disappoint for the first 15 or 20 minutes, but then it became quite the surprise. It's kind of an Ultra Greeny's critisism of the current hysteria and solutions, and he tears them apart.

So while I couldn't live in his ultimate Utopia, he is just as cynical (and knowledgeable) of the current stuff as normal people are.

Under everyone's radar screen on 09/03/2020 was the announcement that the QuantumScape (with the potential of 2.47x aka taking a VW Golf from 188 mile range to 466 miles ) is going public after hundreds of millions being given to them by the likes of VW (primary customer it is said) and others to develop their battery.

BTW this is not investment advice etc. I have been following them for a while, interesting tidbits/rumors have emerged about the technology, petrovites vs anti-petrovites, ceramic membrane vs electrolyte and it is anode-less, has me wishing I did better in H.S. Chemistry :). The link below has only drawing / official explanation of their Technology to date that I have seen.

Nobody seems to be talking about the process of making the batteries that power everything from our phones to the electric cars. I was informed by someone who watches this stuff that the process of manufacturing the batteries, mining the Lithium, everything that goes into it... is an environmental and human rights horror story. Does anyone here follow that side of the story, and can validate/de-bunk/shed light on the environmental effect of making the batteries??

I cannot say I am an expert, buyt I know Africa produces most of the cobalt used in batteries. Mines in Kongo use child labour and owners are chinese.

We have a mine in Finland that is rich in cobalt too...we have lithium too. At least the cobalt mine is damaging the environment.

Are you asserting that the cobalt mine in Finland, that provides material for batteries for (potential) E-AB aircraft and (potentially) the material for promoting the VE resin that I am using to construct an E-AB, is damaging the environment?

There are so many unfounded claims about environmental issues that I don’t accept as fact any claim / assertion without first assessing the supporting data.

Please provide an explanation of how the mine damages the environment.

Well seems that it changes the salt content in the lakes.



It is a local problem...a mine that large in the nature.

It produces also Uranium etc. .....and brings 20 000 jobs to the region.

Cobalt mining has a poor record. It needs great care not to end up poisoning people.

I’m curious about what controls could be used, but are not being ysed, to avoid that problem. That is far away from discussing HBAs, though.


BJC

I agree...all this would have been avoidable. They implied new technology without knowing all its aspects.

What electric car manufactiurers are not telling people is the amount of high-frequency radiation which come out of the speed controllers and is not shielded enough. I was in one of the recent fast Tesla cars and I managed to find out how much residual radiation was in the cockpit. The owner quickly sold the car after two momths because, after having driven it for a week, kept having these increadible headhaches, which specialists could not justify in any manner. One week after he stopped driving it, his headhaches completely disappeared. I personally will never buy an electric or hybrid car. If it petrol cars will one day be banned, I will build my own electric one, choosing what I need.

Do you have any references to support this claim of radiation from speed controllers? What wavelength is this radiation? Thanks
