Sure, but why was Tesla able to start up and take a big portion of the EV market over the last few years? The big companies were too slow in reacting to changing demand. It took years to get something that was equivalent to what they are

No more than I trust the government to work on passing on reduced costs in the form of lower taxes...

>surely making the government pay less money for the same services is a good thing? Is it? Are they actually paying less...or is the cost being dumped on to someone else? This is like saying people who get SNAP benefits are paying less

You can look at the Pandemic assistance that the federal government put out as a great example of how they incentivize not being a productive member of society. $600 a week above normal unemployment benefits...more than half the people mad

It's only waste if you aren't one of the people pocketing from the inefficiency.

The bigger you are the harder it is to do things properly or react fast enough to changing conditions. This is why most companies get huge and then end up failing...they can't change fast enough to stay competitive. It's one thin

If the US confiscated all of the wealth of the billionaires in the US (which would absolutely wreck the economy as well as that wealth, since much of that their wealth is tied up in stocks)...it would fund less than a year of government spe

Relatively useless...but if even a few percent of people recycle passwords used for banking or crypto platforms it could be a profitable cache of data.

This is why most if not all trades have apprenticeships. You have to know what to do and all see what to do...otherwise you could screw something up because you misinterpreted the instructions or design.

I would say there is no way to 100% cover with reading what you need to learn on the job. Also there is no way to cover some concepts with 100% on the job training (much harder to make a HS grad a petroleum engineer by just throwing them o

Just having underground lines doesn't stop everything...and no one has underground lines for extremely high voltage.

600k gallons for us is not all evaporated, thats just what we take in from the city and discharge back to them. There are temperature requirements for discharge as well so you can't just discharge 200 degree water. That doesn't

Everything is built for seismic safety, but that doesn't mean you won't have to scrap a ton of wafers or have any damage if there is an earthquake.

What exactly are you thinking? We have a closed loop system on our process cooling water but it is cooled via heat exchangers that use chilled water (in the 40-50 degree range). That water is chilled with extremely large chillers that use

Power bumps are a major issue and even with redundant power you get them. Even a bump that loses 15-20% of voltage on a single phase for 3-6 cycles (of 60Hz, so like 0.05-0.1s) is a huge impact to fab production tools. I've seen impac

That number seems really high, but the state website seems to be at least close to that number (146gal/day/person or ~600gal/day for a family of 4). https://new.azwater.gov/conservation/public-resources

No semiconductor site has enough backup generators to run continuously and you can only have so much diesel onsite to run those generators (a few hours or maybe a full day if you are lucky). They are there for basic safety systems, air han

In this case I can't compare it to agriculture. I don't think growing food in a desert is a good idea either. The Intel site in Portland, OR uses ~2 Billion gallons of water per year. They claim they are bringing enough recycle

Most managers don't either and will deal with some amount of loss of productivity...but part of that is also a calculation of "how long will it take to train a new hire X to do poorly performing employee Y's job" as well

Absolutely it's a strange choice. From a power perspective it can make sense since solar works very well, but from a water perspective it's a very strange choice. Cheap land is also a very big factor. TSMC purchased over a thou

You can't just have AC when it comes to industrial cooling. You have to have chillers connected to cooling towers and those work on evaporative cooling. Feel free to debate all day on this though...I literally run the department in c

The latest 300mm fabs use 10-50X the power of what the old 8" fabs used (I know this for a fact...). That power gets turned into heat and that heat has to be removed. I work at an "inefficient" 200mm factory that has pretty

>Fabs need a lot of water, like a swimming pool. Once you fill it up, then you need comparatively less to stay operational. This is just not true. The amount of cooling required for fabs is extremely significant and without major evapor

You are correct and there is already a bunch of off the shelf contracts that are basically plug and play...however it takes little knowledge to actually publish said contract and a small typo can either make the contact never accessible or

Not just 23x...but 230x transaction value ($23M to send $100K). Not to mention it was 7,700,000x the going rate for the other transaction in that same block.
