Re: Wind and Solar vs Coal, Gasoline, Nuclear

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.

Re: Wind and Solar vs Coal, Gasoline, Nuclear

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!!!

Re: Congratulations chemists!

+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...

Congratulations chemists!

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...

Re: Wind and Solar vs Coal, Gasoline, Nuclear

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...

Re: Wind and Solar vs Coal, Gasoline, Nuclear

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...

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

Re: Greyhound stopping western Canada service from Manitoba to BC

Whenever my wife and I go back to Canada to visit, we take the train from Vancouver west.

The train is much more expensive, but com...

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.

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.
