Endless Sphere

Yeah I'm all for innovation in renewable energy generation and dispatch, but solar thermal does not stack up. The same sum of money would have bought a decent PV array and some batteries and achieved far more.

Posting about single or multiple weather events as proof about climate change has always seemed pretty dumb to me but its never stopped anyone doing it. So here it is!!! The climate "Experts" said snow in Australia would be a thing of the past 10 years ago, except this year Australia's biggest ski ...

+1 on the congrats. Really a game changer. But why did it take so long to get the prize? That's the nature of the Nobel Prize - the significance of a discovery is often not known for many decades. Sometimes it's much faster, depending on the environment the discovery is made - Michael Smith won the...

John B Goodenough, M Stanley Whittington and Akira Yoshino, chemists who published the seminal work on lithium ion batteries in 1980, were awarded the Nobel Prize for Chemistry. https://www.abc.net.au/news/2019-10-09/nobel-prize-in-chemistry-for-lithium-ion-battery-development/11588298 :bigthumb: :b...

In the 80's I knew guys in Queensland who would build a 'battery fire' consisting of heavy gauge corrugated roofing iron at a slight incline on a concrete slab. An enormous bonfire was prepared with about two dozen old car batteries in the middle. Once well alight they would stand back and watch the...

The dead simple stuff is also the low value stuff. Recycling lead batteries is 99% circular because of the very high value of lead, and the desire to keep toxic metals out of the environment. I can't see why Li-ion battery recycling wouldn't be any different. Found this video well worth watching: ht...

From this paper: Sag is a sign of increased internal resistance, but not necessarily loss of lithium inventory, which is capacity loss.

You spend precious waking hours making memes?

Wow.

Remember how all those stupid scientists in the 1970s were predicting an ice age?

No.

I should have used the [/sarcasm] code

Remember how all those stupid scientists in the 1970s were predicting an ice age? Well, I don't actually recall seeing any worthy literature suggesting this was a possibility. If it was legitimate, there would be peer-reviewed papers documenting it. But alas, nothing. Turns out it's a myth, should y...

Whenever my wife and I go back to Canada to visit, we take the train from Vancouver west. One Christmas we stopped in Edmonton and took the Red Arrow to Calgary, the other time we continued on to Winnipeg. Next time we will probably go all the way to Ottawa. The train is much more expensive, but com...

I'm sure there's a way to spin this in a negative light... just wait

While Adam Smith got plenty right, I don't think he could have predicted that the tragedy of the commons would become a global phenomena. At a time when the oceans were teeming with fish, forests full of trees and seemingly abundant coal and coke, many of his prescriptions were well suited. I also d...

On the subject ot the Dalhousie laboratory results - this is a a very comprehensive paper, and sort of serves as a 'smack-down' challenge. Come up with a better chemistry than this and we'll eat our words. It seems the electrolyte composition was the greatest contribution to Li-ion battery chemistry...

I think it's just white silicone or sikaflex - a waterproof sealant?

Dude, she's not running for office. She's not even telling people to listen to her - she's telling people to listen to the scientists who are authorities on the matter. She's just the messenger of the same message we've been warned of for the past 50 years. What global movement for positive change c...

Geeez, the last few posts here are getting absurd. Why is Greta getting all the attention and other 16 year olds aren't? For the same reason Grumpy Cat became a meme. And why Nyan Cat became an internet sensation. Or Nek Minit became a catchphrase. Welcome to mass communication in 2019. Her ability ...

Some other Isuzus in the mix there too. The upside is a huge payload and lots of space. The downside is big cost and lots of weight to move.

You are talking about controlled enclosed experiments in a lab. Yep. Science, which proves that higher concentrations of CO2 cause more heat to be retained. This experiment can be repeated over and over, to prove the above statement is absolutely true - the same statement you denied not five posts ...

In case you didn't know Greta, here is a full interview to get acquainted with the next Nobel prize winner. . https://youtu.be/Dgi30Wy_V74 . She is amazing, and has a gift. And that gift includes the incredible ability to trigger middle-aged white men from the developed world into realising how pun...

Just a quick post to report on two 18650 cell suppliers from China. I'd tested (LG) LG18650-MJ1, (Samsung) INR18650-35E, (Sony) NCR18650B and (Sony) NCR18650BD Cell test results.JPG 25 of each, with standard deviations represented as error bars. Testing was done with Lito Kalia 4-cell testers using ...

If I may distill the last 200 pages into two world views - I am motivated to make these decisions for the greater good of all others, not just me. Or I am motivated to make these decisions for the exclusive benefit of myself and my tribe, screw the others. The claim that we should exploit our abunda...

That's a pretty big risk to be taking on your first order! I hope everything turns out OK. Are the batteries for your race car? No, these are for two separate projects. One is re-packing a Mitsubishi iMiEV with a larger capacity battery, the other is for a friend's own EV conversion. In my case the...

Hi all, I have ordered about AU$14,000 worth of battery cells from Jack Zhang at Liyuan battery in China. For those who don't know, Jack Zhang is the one constantly posting spam on people's EV related Facebook pages about prismatic NMC and LFP cells. He pestered me every day until I finally placed a...

I just wore my "I <3 Pumped Hydro" shirt.

Was great so see about 10,000 in the streets of Perth. It's a pretty conservative old town, so hopefully the kids keep it up.
