USA and Russia got the rocket scientists from the defeated Nazi German.
Their V2 rocked killed more jews workers (slaves at the time) manufacturing it, than the english people during V2 atacks.
Von Braun, despite the fame of hero of space race, was who sellected jewish workers to the nazi german project.

I don't know about these operations.

On Brazil we are told that Santos Dumont is the inventor of the airplane. But I know both, Wright Brothes and Dumont have greate roles. Wright brothes didn't toof off alone and was very short, but they did first, while Dumont's 14 Bis took off and was much longer and with a smooth landing.

Anyway in a documentary they showed another guy did a better flying even before Wright Brothers. Took off and landed. But didn't care to register well this fact.

These impressive techno-changing 54 years will never happen again !!!

I know Sputnik is probably before your time. What do you think of the hypothesis that Operation Paperclip was sabatoging the American USAF program, so it was taken from them and given to the Army before any success — then JFK bought the Hungarian space program from Tito and that became the Apollo program that went to the Moon?

54 years from the Wright brothers to orbit.

I remamber a charge cartoonist who did a nice drawing about plastic and progress.

It showed a scientist holding a plastic piece in the 40's and smiling, saying : "Plastic will last forever".
And in our actual time a scientit was sad and depressed holding a piece of plastic and concerned saying : "Plastic will last forever."

23000 cycles?

Sodium, a alternative:



And:

I had saw some video where a company was to release a battery with 5x the energy density of lithium, but I don't really belive. If I found the video again.

The end of fossil fuel doesn't have to throw us back to 1850. Capitalism will save the day.

The "middle-of-the-road" stradling the North and South rims of the Grand Canyon is a l-o-n-g mile down...sometimes being "centric" is not a realistic option.

This, if was true (10x more energy than lithium) would be a breakthough :

5x to 10x the energy density of lithium batteries?
Nope I'm calling BS on that.

The most energy dense chemical storage know to man that isn't too weird and could be useable is to oxidize aluminum with oxygen from the air. It's about 4 or 5 times the energy density of lithium batteries.

So when someone one says "my battery is 3, 5 or 10 times more energy dense than current batteries" the laws of physics say you should be skeptical.

Going back to the opening post of this very lengthy conversation, it's ridiculous in this day and age that folk still think something must be correct simply because there is a 'consensus'. More people than not agreed that voting Hitler in as chancellor would be a good thing, and there were eventually proven very wrong indeed. Citing consensus for a reason in believing in something is Emperors New Clothes syndrome.

Make up your own mind based upon the evidence laid before you. Don't be bullied into an opinion because someone is claiming a consensus, and therefore must be right. That's what gets us into these messes in the first place.

I have not watched it yet and right now I am trying to figure out an assignment due almost two days ago.

Responsibilities are fun.

Potholer54 is also very well versed on climate change.

https://youtu.be/52KLGqDSAjo

Unfortunately his new energy video lacks some important information. He states that wind electricicty in China is often curtailed. Implying that they have so much electricity that they can't even use it all. But the the problem is that the good wind resources are 1,000's of km from the cities that need the electricity and there is insufficient transmission capacity to carry that much power all the way across the country.
.
He also neglects to comprehend that electricity consumption in China when converted to mtce and viewed as a percentage of primary energy consumption, electricity is only 12% total energy consumtion.
.
https://china.lbl.gov/sites/default/...2017-final.pdf
.
So even if they were to replace all of electricity production with 5X more Nuclear, Wind, Solar, and storage than is currently online, and gained a 2X efficiency by converting all of the built out infrastucture thermal processes and machinery to electric, if that is even conceivable, they would have to increase their 5X of new clean electricity by another 4X.
.
20X their current clean energy build out. Plus 100's of TWh's of storage.
.
It's not so easy as he makes it sound.
