If the center of gravity of a turbine rotor is out by one millionth of an inch, it can throw off the stability of the entire machine.

This is so small that the heat generated by friction during the balancing process must be mitigated in order to get proper balance.

[stephen balaban @stephenbalaban]

100% Agree @GavinSBaker. Now, I'm going to debunk every single piece of mis-information about data centers that I've ever seen online:

> DISINFORMATION: Data centers use a lot of water.

FACT: Most AI data centers are closed loop dry cooler design that barely consume any water at all. A 20MW 10,000 GPU cluster needs 20,000 gallons to charge and doesn't use material water after that. That's less than 1/4 of the amount of water used to raise the amount of beef the average American consumes in a year. That means one of the largest data centers in the world, at 2GW, consumes less water than 20 people's annual beef consumption or three American's total water footprint (@ ~600k gallons per year for the average American).

> DISINFORMATION: Data centers increase electricity prices.

FACT: Data centers bring down a community's average electricity bill because they spur development of new power generation. Most data centers bring their own power generation, pay fees to the utility to build more power plants, or bring their own power storage to actually reduce the cost of energy in their community. Northern Virginia has some of the most data centers per capita and has low power costs. See research from the Electric Power Research Institute https://t.co/8fMZcIgMhx and https://t.co/KK04Pl8998.

>DISINFORMATION: Data centers don't create jobs

FACT: Data centers create hundreds of jobs at construction and a high number of exceptionally high paying jobs (many over $120k/year) for their ongoing operation and maintenance. No, they're not similar to an automotive plant in terms of the jobs / MW but they are phenomenal additions to an industrial park and community.

> DISINFORMATION: Data centers are constantly super noisy

FACT: Data centers are one of the quietest industrial buildings in the world. Drive by a data center in your city and roll down your window. They are very quiet. In fact, a metal mill is FAR louder than a data center---up to 10,000,000 more sound energy is produced by a mill and perceptually a mill can be 128x louder than a data center.

> DISINFORMATION: Data centers emit noise pollution from diesel engines running all the time.

FACT: Emergency generator sets are almost never turned on unless the grid connection goes out. This would be less than 0.5% of the time!

> DISINFORMATION: Data centers are surveillance systems

FACT: Data centers actually just host computers owned by private companies that are used to make phone calls, access the internet, run ChatGPT, Claude, X, Instagram, Facebook, Google, play multiplayer video games, and every thing you ever do online. That's it.

> DISINFORMATION: Data centers make water dirty

FACT: AOC held up a bottle of dirty water and said this is what data centers do. Completely false, well water disruption is a rare side effect of EVERY construction site in the history of humanity. This is not at all unique to data centers and is a complete red herring.

> DISINFORMATION: Data centers get massive tax breaks and drain tax dollars from towns

FACT: Data centers pay massive amounts of tax and often times huge % of an annual budget of a county or town! It's an absolute bonanza for the towns that are lucky enough to welcome a data center. New schools, new roads, new services are all paid for. Even if there is a sales tax rebate we're still talking tens of millions of new tax revenue. In 2022, Virginia’s data centers collectively generated $1 billion in local tax revenue and $640 million in state tax revenue! That was 2022. https://t.co/Oijl1TC7yb

Feel free to reply here if you have any other question you'd like answered about data centers happy to provide actual facts.

[David Perell @david_perell]

The decline of beauty in everyday life shows up in even the smallest things, like tickets, where we’ve let our obsession with efficiency win out over personality and artistic expression.

Like the ticket from the Guggenheim Museum in New York, which I've shared in the first photo. It's an iconic building that could have so easily inspired a beautiful ticket design, but they opted for the most economical option instead.

Each example of this decline isn't a big deal, but the world becomes less charming and enchanted when people stop caring about craftsmanship.

For some alternatives, scroll through the photos. The second one shows old Japanese train tickets, the third one shows an old circus ticket, and the fourth one is a World Series ticket from 2002, which felt magical when I got to hold one as an eight-year-old.

So yes, there’s definitely been a decline. And maybe we’re okay with it! But it’s worth remembering that this decline isn’t inevitable. There is another way.

London sits at about 51.5°N and Calgary at 51.1°N, essentially the same line. London's mean January temperature is around 5.5°C; Calgary's is nearer minus 10. The difference is the North Atlantic Drift, without which Britain would run over 5°C colder.

It's more than a miracle, it's proactive intervention and progress driven by both curious minds and advocates for safety. It's decades of unending cumulative effort by engineers, pilots, and regulators to make their next flight their best one.

This is what @SpaceX's Starbase, Louisiana spaceport will look like.

It looks absolutely incredible. Multiple launch pads, and one beautiful location.

[Elon Musk @elonmusk]

Megatons to orbit & beyond is a critical piece of the K2 puzzle.

The other parts are: massive amounts of solar cell production, AI chip production, millions of humanoid (general purpose) robots and a mass driver on the Moon.

My guess is that ~1M Optimi plus ~1GW of solar will constitute the first Von Neumann Probe, a system capable of replicating itself entirely from local materials on any sufficiently large planet or moon. This would enable expansion of civilization throughout the galaxy and reaching K3.

[Elon Musk @elonmusk]

Starbase Louisiana will ultimately have over a dozen launch towers, enabling more than 30 Starship flights per day and making it the biggest launch site on Earth!

SpaceX makes sci-fi real.
