Problem1 : You would need conduction (from each cpu/gpu in the server toward a radiator using cooling liquid for example) from the rack to a radiator.
Otherwise if you don't those 100kW would be dumped into very small surface of the GPU/CPU and small radiator they usually have.
At 300K blackbody radiance is ~450 W.m^-2 So you r calculation of the surface of the cylinder is OK, you would only need 222 m^2 to dissipate a blackbody at 300K of 100kW of heat. The problem is that the heat is not dumped into the cylinder directly, but would need to be conducted from the cpu/gpu radiator to the cylinder . And that's where the problem starts, as you would need almost certainly a liquid for the transport, and that brings a lot of issue itself (weight, pump failure, freezing/boiling etc...). And that's not even counting servicing & obsolescence.

IMO the feasability of this is near null zero enough to be disregarded as a tech bro stupid solution in wait of a problem.

much MUCH easier solution is to have the server on earth, in zone where you have a lot of renewable like solar, wind. easier to maintain , cool, and give energy.

microwave labotomy ... We just put the machine against your head here for a bit and those bad urges go away, all better.

Another poster mentioned that it's actually focussed ultrasound.

Still sounds like breaking a piece of a system by stirring the brain with a knife (lobotomy) or burning it out with heat (cauterization), electricity (electroshock) or mechanical shock (blow to the head) - just carefully focused without (substantial) damage to other parts of the brain or its casing.

Ultrasonic destruction of a piece of the brain's reward/punishment/desire/avoidance mechanism rather than persistent unwanted fat.

You might want to read up on how current hybrid vehicles actually work, 'cause it seems you have more than one misconception going on.

I have. For instance, my latest vehicle is the Ford F-159 XLT,, the full-hybrid model of the F-series pickup truck line. Power train is:
  - 6 cylinder dual-turbo engine. (runs low power but approoximately doubles output when a lot is needed.)
  - 47 HP motor-generator "pancake" on the engine side of the ttransmission, to scavenge / return power to./from a 1.5 kWhr lithium battery.
  - 10-speed automatic transmission, working with the lithium battery;s main alternator to fine-tune match the engine/mogen to the current driving situation. Max power of engine plus hybrid mogen; 430 hp.
  - full four wheel drive.

So it's primarily a gas-engine power train with an electric-car motor mechanically coupled to the engine shaft. Many other hybrids, from the venerable prius onward, are similar, with plug-in variants having a big scavaging/peaking battery good for pure electric operation of tens of miles rather than a minute or so and a wall-powered charger added.

What I'm looking for is essentially a pure electric - totally electronic "transmission" consisting of alternator(s) between the batteries and the motor(s), plus a tiny engine-generator able to burn gas and feed some teens of KW of charging power into the batteries when running down the road or parked near it.
 

Do the Waymo batteries use one of the lithium chemistries including cobalt, or a non-cobalt chemistry such as lithium iron phosphate?

Cobalt chemistries have a higher power/weight and energy/weight ratio, which made them the go-to chemistries for vehicle batteries. But they also produce oxygen when the cells overheat, leading to an unextinguishable runaway fire hazard: A burning cell makes enough heat to ignite the adjacent cells, so the whole assembly of them goes. Bad enough when it's a car's worth, but a disaster if it's a shipping-container sized module of a utility energy storage site. (And even worse when the site is a building full of racks, which someone had "protected" from fire with water-spraying, equipment-shorting system, so the whole site burns up, as happened recently with one in California creating a toxic mess.)

That's why purpose-built stationary lithium energy systems use non-cobalt chemistries - heavier, but a shorted cell just kills itself without getting hot enough to light off its neighbors.

I want to see inexpensive plugin hybrids.

But not like the current ones, which are primarily an engine/tranny powertrain with a motor/generator + small battery for scavenging downhill/braking energy for later accelleration/uphill/cruise/power-boost.

I want ones that are primarily a battery-electric with a small aux engine-generator (say 15-20 HP range), big enough to power crusing with a bit left over for gradually charging. That would let you range-extend by the size of your gas tank plus fillups (i.e. indefinitely if only gas is available) or go from battery empty to back on the road in a couple tens of minutes.

The backup engine would only run at max-efficiency speed and could use an atkins-like cycle (see "liquid piston engine") to get the max power out of the fuel. Most operation would use power-grid charging (when available and cheaper than fuel).

Jensen Huang to college grads: "Run. Don't walk" toward AI

https://www.axios.com/2026/05/...

Nvidia founder and CEO Jensen Huang told graduates at Carnegie Mellon University in Pittsburgh yesterday that demand for AI infrastructure is creating a "once-in-a-generation opportunity to reindustrialize America and restore the nation's capacity to build."

Why it matters: With many college grads fearing AI could obliterate their career dreams, Huang pointed to boundless opportunity as a "new industry is being born. A new era of science and discovery is beginning ... I cannot imagine a more exciting time to begin your life's work."

Nvidia, which makes AI chips, is the world's most valuable company. Huang told 5,800 recipients of undergraduate and graduate degrees that the AI buildout will require plumbers, electricians, ironworkers, and builders for chip factories, data centers and advanced manufacturing facilities.

"No generation has entered the world with more powerful tools â" or greater opportunities â" than you," he said. "We are all standing at the same starting line. This is your moment to help shape what comes next. So run. Don't walk."

"Every major technological revolution in history created fear alongside opportunity," Huang added. "When society engages technology openly, responsibly, and optimistically, we expand human potential far more than we diminish it."

Bold of you , to imagine that by that point in a few decades, that lake still exists.

...like "Tell me about Tiananmen Square" or "Tell me about Xinjiang".

Is this what you want for the future?

My thoughts back when R1 came out:

The issue is too many people don't look at political party plans, they simply adopt a political party as their identity. They are not republican (or democrats!) because GOP propose plan with item 1,2,3, but rather because being republican is part of their identity. Once that happens and facts goes against that political party, it make the brain analyze it as an attack against identity, and use defensive reaction mechanism to protect identity, chief among them wholesale rejection of facts.

This is not only the republican which do that, but republican happens to be associated with right wing / authority / strength as an image (not necessarily a truth just an image) and far more likely currently to have the facts going against them.

They (conspiracy theorist from r/UFOs) take

1) a long period of time (the first "case" is from july 2023)
2) they take various profession and places mashed together
3) various situation mashed together (missing, suicided, murdered, one guy missing stating he did not want to live with his brain deteriorating etc...)
Then suddenly they find out there is a dozen such a case.


The thing is I would be not be surprised if you take so many different places, and people, over so many years, and check for disappearance/murder/suicide you would find similar number, but nobody will make a CT over your random white collar guy.
