Santa Calculations 2022
Time to republish the Santa Calculations, which I first published back in 2006 and then updated in 2010. Then I was using 7 billion as the world population. Now its 8 billion.
Firstly, here's the link to the Santa tracking system created by NORAD.
For those of you who are more interested in the technology of Santa, NORAD's FAQs provide the following:
I've again used the Joel Potischman and Bruce Handy calculations as the basis for the speed calculations, with my own adaptations:
The most notable corrections to be applied are:
- Santa delivers no gifts to naughty children (not even coal)
- Naughty to nice ratio is 1:9
- As confirmed by NORAD, one Santa distributes all of the gifts.
- There is only one family per household.
- Santa bypasses non Santa belief system houses.
- Reindeer have recently eaten fresh magic acorns.
Calculation Assumptions (2022):
- World population = 8.06 billion
- Children under 18 = 2.689 billion (Hmm may be higher)
- Global Santa based belief systems: 33%
- Max children requiring delivery therefore 887 million
- Children per household: 3.5 (may seem high?)
- Number of households requiring distribution 253 million
- Naughty to nice factor applied but not many all naughty households
- Remove all naughty households (25% 0f 10%) = 6.3 million
- Eastern orthodox using Jan 5 instead of Dec 25 = 18.2 Million
- Target Households = 234.8 million on Dec 25
- Estimated child bed time 21:00 (9pm) with 7 hours sleep.
(child sleep duration on Dec 24 may also require revision)
Gives circa 31 hours (24+7) for all deliveries
Time is 1860 mins or 111,600 seconds
The average number of homes to visit per second = circa 2096.
So average delivery per household is circa 500 milliseconds, which is why Santa normally appears a bit blurry (I previously thought it was the sherry)
Land surface minus Antarctica is around 79 million square miles. Distribute destinations evenly = 0.7 miles between households creating a total distance of circa 110 million miles.
So 110 million miles in 31 hours = 3.6 million miles an hour or circa 1000 miles per second or Mach 4770 at a linear speed.
This explains Rudolph's red nose because of air resistance creating around 20 quintillion Joules of energy per second, which would convert a non-reindeer nose to charcoal at such energy levels. I think the acceleration and deceleration per household may also need some examination.
Luckily Santa has lots of special powers so these mere physics facts are no problem to such a superhero.

Tesla: worth a punt?
They have dropped to about half of their start the year position and therefore could be seen as a bit of a bargain. The drop is consequential on the twitter shenanigans and various short-sellers throwing out rumours about the share price.
But consider: the company has a gross margin of around 25%, which is ridiculously high for the automotive sector. VW is 6.2% and BMW and Ford are about 15%-16%. Additionally, it had a suite of Gigafactories just to produce EVs. A couple of these (Berlin and Austin) are only ramping up production at present, from around 60k/Qtr compared with the Shanghai Giga factory at 250k/Qtr.
Other manufacturers are repurposing their gasoline vehicles to electric, leaving the transmission tunnel in place and making a few cosmetic changes to the exterior. They say it is so they won't scare the client base. A client base buying a legacy adaptation. I followed an electric beemer along the road the other day and it even had the two cutouts for the dual twin tailpipes. They surely miss the point about a paradigm shift (I know, extra consultant bingo points for that mention).
The predictions are for Tesla to ship around 500,000 cars in 4Q22, which makes a total of around 1.4 million vehicles. Consider that BMW produces 2.2 million or 2.5 if we include the Rollers and Minis. Conceivably Tesla could be bigger than BMW in another year.
Assuming that there will also be a Tesla share buyback during 2023, the share price could rise, in line with both the results and the effect of the buyback.
But I also look for ideas and the rumoured Tesla Model 2, or whatever, is of immense interest. It reminds me of our Alfa Guilietta. If a denuded Model 2 comes in close to $25,000 then it could be a real challenge to the lower end, knowing it will come with the same chipset and operating system as the high end vehicles.
Now factor in the truck and the improved so called self driving, and we have a string of interesting enhancements.
But let us not forget Tesla is down 51% year to date. Rivian is on life support at down 74%, Nio has dropped 61%, and even Ford is down 36% over the same period.
The difference is that Tesla is kitted out with Gigafactories ready for pure EV production.
No recommendation here, just an observation.

Strange Games : Slow Horses S1 and start of S2
- Because it forced me to go back to the first series and watch it all over again.
- Because we are now only on book 2, and I'm eagerly waiting for episode 3 to drop.
- Because I know there are at least five more books in the Mick Herron series. Oh yes, and Mick Jagger wrote and performs the theme.

schlecht
I'll be off to my Stammtisch later for Weihnachtsfeier und Geschwätz. Sad to see that actions of rogue right populism have now leached into the German system, creating an attempt to storm the German goverment buildings.
These far right protestors are using the ant-vax capaign to drive support for their wider goals. They previously used Merkel's acceptance of migration and fears of islamisation.
The AfD (Alternative for Germany) uses its legitmised position to cultivate dissent and even includes 83 members in the German Parliament. Infiltration is part of their modus operandi.
A German military KSK (Kommando Spezialkräfte) special forces unit was disbanded recently because it contained many extremists. Discovered buried in the garden by police, a Sergeant-Major's house had two kilograms of plastic explosives, a detonator, a fuse, an AK-47, a silencer, two knives, a crossbow and thousands of rounds of ammunition, much of it believed to have been stolen from the German military.
Some 48,000 rounds of ammunition and 62 kilograms of explosives have also 'disappeared'.

art of the dodge
Remarkable that the dodgy ex-president has now been found guilty on 17 counts of financial crime including tax fraud. How remarkable that he can bounce free from this with a mere $1.62 million fine, which I expect he will contest.
Plenty rests on a Mr. Weisselberg, who struck a plea deal with prosecutors. Weisselberg admitted that he had reaped about $1.8 million (ie more than Trumps fine) in indirect and hidden compensation, allowing him to evade hundreds of thousands of dollars in taxes. The benefits included a rent-free apartment in a Trump building overlooking the Hudson River; leased cars for him and his wife; and Trump-paid private school tuition for their grandchildren.
The above 2018 art installation inside a Trump hotel hinted at what was to come. I wonder how many others are hoping to avoid the searchlight?
Trump is naturally calling it all a witch hunt.

#LTN: watching and waiting
Twitter has become the news in its own right, a little like some journalists who stumble into the story. I'll bide my time to see how it plays out. After all, many well-known names have been around on the system for a long time. I guess I'm also a #ltn (low twitter number)
Anyone can find out this stuff.Despite all the naysayers, I suspect Musk will weed most of the pile-on-noise-merchants out of the system.
But then, I'm holding economically priced Tesla shares as well, since they temporarily became discounted.
