How long do you think semiconductor shortage will continue?

Current vehichles are extremely picky about the fuel you put in them, plus you will obstruct all the stupid filters and scr systems in like zero time and make the vehichle uselss, because as per requirement from the law it won't even start if you remove the system and don't fool the ECU or reprogram it

That is annoying, although I was surprised to discover some time back that I could make a small (lawnmower type) engine run quite well with the carburetor completely removed by just poking a hose from a propane tank into the intake. I'm pretty confident that if push came to shove I could convert a relatively modern car to run on some alternative fuel. One of my cars has both the original fuel and ignition systems removed and replaced with the open source Megasquirt, it's a bit of a hassle to get it dialed in but it will work on just about any non-hybrid ICE. Marine engines are also mostly devoid of any of the modern mandated automotive tech and many are marinised versions of production car engines so that is another option.

The only outcome is that costs increase massively to provide redundancy via multi sourcing.
Back when I worked in the defence sector we multi sourced most stuff and what we couldn’t was bought in massive quantities to act as stock for repairs and future supply. And the clients were charged up front for that.
What killed some of this is the ridiculous product refresh cycles we see these days. We need to slow everything down.

What changed to this can be changed back. If it continues to be a catastrophe some smart company somewhere will figure this out and implement something that works.

On the other hand, some people have a big reaction to vaccination, for example, high fevers for 14 days and so. No long-term effects. But cannot afford not going to work for this long time. It is a big problem.

Some people, yes, but they are exceptionally rare. I don't have the actual data in front of me but I would speculate that for every one person that has a serious reaction from the vaccine there are probably 1,000 or even 10,000 people that have a serious reaction to the Covid virus. There is a non-zero chance of having a severe reaction and dying from eating some ordinary item of food, but it is still safer to eat food than to not, because you will eventually die if you don't. Seatbelts occasionally kill somebody who would have survived had they not been wearing one, but no sane person is going to suggest that seatbelts don't work, we have massive amounts of data saying otherwise. Being out of work for 14 days would be a big problem for a lot of people, but I'm going to guess that if they are dead or even just end up in the hospital due to a virus infection they will miss a lot more work.

Got an email today from a manufacturer saying some factories in Guangdong province are now working 2 days a week and some are stopping for one month immediately because of electricity limit the government just announced.
I think China often has pollution problems in the fall as everyone turns their heaters on. I remember reading about some shutdowns because of it in previous years. Guessing this electricity limit might have something to do with that.

Commodities pricing is just crazy. Almost all of them- coal, copper, aluminum, natural gas are 150-200% up. Coal is up 160%.
I wonder when china will cower and buy more Australian coal :popcorn: But factories in guangdong starving for power is a disaster heading into winter.
There is some kind of big bubble inflating, with energy, commodities and shipping costs.
