It possible the energy industry remains far too quaint about what’s happening.

We may have a truly gigantic new source of relatively inelastic demand.

@ShanuMathew93 A big blind spot for the AI industry generally is their hyper fixation on coding ability as the ur-performance metric. the vast majority of their TAM does not care at all about coding ability.

NOO ZOHRAN YOU CANT JUST DELETE RANDOM SECTIONS OF HV PIPES

[Jaketropolis @jaketropolis]

🚨 Zohran Mamdani has accidentally deleted a crucial length of high voltage wire and water pipe in New York City.

This went ignored for 10 minutes while he detailed a park, causing over 150,000 buildings to become abandoned.

@compliantvc Sure yes carbon credits, what about also requiring methane, ethane, benzene credits? Nitrogen credits? Oxygen credits? We must rain in Elon before he uses up all the air for his rockets.

exiting whoop after 18 months.

kept the strap, ditched the subscription. it now runs fully local on zhoop (my fork of noop). no fluff metrics, my data stays on my phone.

ai killed vendor lock-in.

@ShanuMathew93 This is so confusing - i thought this was abt their project chile pipeline declaring FM but it’s different? Also isn’t oracle the developer? And is the conflict FM being exercised or simply the FM right being included as a contractual term?

Like they had noise cancelling Blackhawk helicopters in Zero Dark Thirty don’t tell me there’s nothing we can do about this stationary 1-story building

[henry f @hfrenchk]

The solution is to regulate noise in dBA and dBC, the latter being a low-pass filter that more accurately measures low frequency noises like engines or bass. Otherwise yea variable fan drive controllers are a good example of how we solved noise if you have the money

[Gaurab Chakrabarti @Gaurab]

People assume a data center hums because thousands of computers are running inside it. Almost none of the sound reaching the neighborhood comes from the computers.

A GB300 NVL72 rack draws about 140 kW. Essentially all of it leaves the building as heat. Amazon’s campus on Tanner Way runs more than 400 rooftop exhaust fans, about 600 feet from the houses in Great Oak.

Prince William County allows 55 dBA at night at a residential property line, and campuses are designed to come in under it.

But here’s the catch:

Fans and transformers make low-frequency tones. Low frequencies travel farther and go through walls. Counties measure in dBA, a scale that barely counts the low end. A 73 Hz hum reads about 24 dB quieter than it is. So a site can pass its noise limit while the people next to it still can’t sleep at night.

How to fix this?

Distance. Sound drops about 6 dB every time you double it. Low-frequency rumble carries farther than that.

Enclosures and silencers. At xAI’s power plant in Southaven, Mississippi, a $7M sound wall went up last December, and the company promised a $12.8M earth berm as well, to screen the gas turbines.

Slower fans. The fans have to get rid of the heat, you can’t just turn them down. Amazon put new motors and better blades on all 424 exhaust units at Great Oak, made the stacks 3 feet taller and rewrote the controls to run the fans slower and in sync.

That cut the noise by about 10 dB, and the fans use less power doing it. It was a four-month retrofit of every fan on the roof. Amazon has never said what it spent.

BREAKING: Oracle stock, $ORCL, falls -5% after declaring "force majeure" on a massive data center being built in New Mexico.

Oracle has reportedly made the move in order to shield itself from rapidly rising expenses on the project.
