We May Not Have Enough Millennials To Even Meet Electric Car Demand
I understood that reference. I think young people who haven't attended college deserve the benefit of the doubt. Millennials? Speaking as a pre-Boomer, nuke 'em from orbit and move on.

Quote:
The one locality in the United States where nickel has been profitably mined is Riddle, Oregon, where several square miles of nickel-bearing garnierite surface deposits are located. The mine closed in 1987.[52][53] The Eagle mine project is a new nickel mine in Michigan's upper peninsula. Construction was completed in 2013, and operations began in the third quarter of 2014.[54] In the first full year of operation, Eagle Mine produced 18,000 tonnes.[54]

Around 1987 I helped build a 60ft geodesic dome church in Riddle, OR. Just the first floor, with a 20-sided 11ft wall. I wonder if they ever got the dome up on top.

Actually, the reference was someone misreading the actual title (not enough minerales, amigo).

I was actually wondering about basements and geodesic domes earlier today. It looks like they just have boring straight walls, but the ones that I saw used Insulated Concrete Form.

Google Maps only shows three churches in Riddle and none of them are domes.

I don't know why page 60 won't load, but from the email notification:

Zoom in on the Open Bible Christian Center. It's a flat roof. While we were building the first floor, the discussion was whether with the mine closing, they'd ever be able to complete it.

There is a 60 footer we did complete at https://www.google.com/maps/@44.0692949,-123.100039,69m

The dome is free-span and requires a level ring foundation, but beyond that it's between you and your wallet.You could reproduce the Playboy Mansion Grotto.

I'll check tomorrow to see if the page loads.

It means it's cold out today. Man hasn't put enough CO2 into the atmosphere yet if we can still have winter. FAKE NEWS!

The immense energy Bitcoin consumes comes from competition among the miners. Without the investment in proof-of-work, the blockchain could be resolved on a single device. That's why I like proof-of-stake.
I just listened to a good Rubin Report podcast where they discuss bitcoin. While I severely underestimated the investment potential of holding bitcoin, I still don't think it's sustainable. We cannot have transactions that take ever more computational power. Not only is it a waste of energy, it's a waste of time. Bitcoin is only capable of processing a finite amount of transactions.

I believe currency will decentralize and ledgers will be distributed eventually, but it has to be done in a way that doesn't require ever more computational power. The incentive to host a ledger and validate transactions should be something other than creation of new e-currency.

Wasn't it last year when people kept asking [not necessarily seriously] "How come we are having all of these blizzards with global warming?!"

"That is how global warming works, you idiot!"

Is more than northern Arizona experiencing a heat wave? People have told me it is normally twenty degrees colder and snowing.

Which way does global warming work?

[I imagine the average temperature is an infinitely better indicator]

Warmer global average temperature is the best overall way to track climate change. But there are several other major affects - one being increased evaporation. And more water vapor in the atmosphere then leads to more precipitation, and also increases the warming, because water vapor is a greenhouse gas.

Another major affect of adding more carbon into the atmosphere, is that more carbon is absorbed by the ocean, and this becomes carbonic acid. The pH of the ocean had dropped from about 8.2 to 8.1 - which doesn't sound like much; but pH is a logarithmic scale, and this is a significant change. It makes it harder for every lifeform that has a shell. Plankton in particular is critical to the food chain, and so lower pH is having a big effect.

Ocean water also absorbs a majority of the heat energy, as well as most of the carbon. And what happens to the dissolved gases in water, as water warms?

It releases gases back to the air. So, initially the ocean has been absorbing carbon dioxide, and now as it warms - it will start to release it. So, there is another amplifying effect that will accelerate the warming.

What we used to call "permafrost" - is now melting. It is now releasing more and more methane and carbon dioxide, from the organic matter that was frozen. If there is oxygen available as it melts, it releases carbon dioxide, and if there is no oxygen, it releases methane.

There is a lot of methane ice (aka clathrates) on the ocean floor. If this melts, then all bets are off.

It does the job.

I'll point out that methane is relatively short-lived (12 years by one source). While it is a potent greenhouse gas, it likes to turn into water and carbon dioxide.

What I'm trying to wrap my head around the last few days is the idea that electrical charge is drawn down from the ionosphere by atmospheric lows and regurgitated from telluric currents by atmospheric highs (unless I have it backward, that being entirely possible).*

Bitcoin as an organic investment was a one-shot deal in early days. Now the leeches are trying to implement Bitcoin futures. It's proven sustainable every time it tanks and rebounds, a Ponze scheme would crash to zero. Equilibrium may be in the range of US$100K. At US$10K a single Satoshi (quantum) is 10.

Understand Bitcoin is a proof-of-concept that escaped into the wild. A [possibly] more mature cryptocurrency is Ethereum. Ether resolve 4x as fast, and currently trade at 1/4 the value, of a Bitcoin. Up 5000% year-on-year.
