Stupid and malicious are different.

The offered narrative is "let us build the data center AI control grid now because it's only temporary until we can move it to space".

You and I both know that's not thermodynamically possible with known science.

So do the people saying it.

We have a real problem with Positive Projection where we are decent folks so we project that on people who are not. That is an error even though most people are decent folks. The parasites are not.

I only recent learned that Hanlon's Razor comes from a humor book about Murphy's Law from the early 80's. It's not some ancient axiom of wisdom - it is used by the Cluster B disordered to mask their nefarious deeds.

If you talk about this with most people these days you'll get the Positive Projection script executed like an autorun.

Everybody should turn off autorun whenever possible. Major risk.

> Gardasil

It's sold as an "HPV vaccine" but it only targets about 4% of HPV viruses, specifically the ones most likely to cause cervical cancer in women in their 40's. It's described in the Merck literature.

Not even the HPV most likely to cause throat cancer in men (usually acquired from lady parts).

If cancer treatment advances at the current rate (AI discovery docs estimate 9 years for the supermajority) it's possible that the Gardasil fatalities will have killed more teens than prevented deaths of women.

It's like a Drake Equation for cancer - the coefficients will determine the narrative either positive or negative. This is where free choice is ethically mandated.

Unfortunately there is considerable religious fervor about such things so very few people wants to scientifically discuss nuances.

Submission + - Google tests AI processor in space (npr.org)

Geoffrey.landis writes: Google just put a satellite testing AI chips into space. The refrigerator-sized satellite is part of a research project, "Suncatcher," the company hopes can pave the way for orbiting AI data centers powered by the sun. The prototype satellite has four specialty chips in it called Tensor Processing Units, or TPUs, that Google designed for machine learning and has already deployed in data centers on Earth. The chips will run a version of the company's Gemma AI model for 15 minutes at a time due to heat management constraints, using the open weight model to answer simple queries. In a blog post, Google said the mission will gauge how the TPUs handle "the physical stress of spaceflight and the radiation and thermal extremes of space." The satellite launched October 1 is a prototype that Travis Beals, senior director and lead of Project Suncatcher, called "a very minimal test" to make sure the chips can run in space. A SpaceX rocket carried it into orbit, and Planet will get it up and running. Beal said Google will then fire up and test the TPUs. The goal is for the mission to be operational for a year.

We'd all be trillionaires if we could see that far into the future with sufficient clarity.

Consider whether a Depopulationist psyop is more or less likely than that The End Times have finally come (unlike the previous thousand pronouncements).

Which is what you'd want to do for any prototype system.

They should then track foot traffic, gross sales, and net profit and see whether the recommendations increased or decreased them when followed.

Having a control group is valuable, not a target for punishment. If McD Corporate were sane, anyway (cf. ice cream machine fiasco).

Comment Hot electrons [Re:Perovskite thin films] (Score 3, Informative) 42

I have some amount of skepticism too. Nanosecond lifetimes of hot electrons are amazing, but to date there's no way for turning hot electrons into electrical energy*. So they'd essentially have to invent a technology from scratch.

Your last sentence... I was just about to post something similar... far as I remember, heat doesn't generate electricity in PV cells... it might even hurt their efficiency, but you beat me to it.

Correct on both, in fact heat decreases efficiency of PV cells (thermal dark current is opposite to photovoltaic current). However, keep in mind that "hot electrons" aren't exactly hot in the sensible-heat sense-- it means that the electrons are in a high-energy state well above the bandgap of the semiconductor. The solar photons come in at an equivalent temperature of 6000K, and all of that energy gets transferred to the minority-carrier electrons, but they quickly shed their excess energy (by transferring energy to the lattice and to other electrons or holes) and relax to the edge of the conduction band (or, ~kT above it). So, using "hot electrons" means somehow finding a way to transfer energy out of the highly-excited initial state immediately after photon absorption, rather than the relaxed quasi-equilibrium state of the conduction band.

So, there's energy there, and in principle it could be used. It's just going to take a new approach to use it. I can't think of a way to do that without adding junctions, and then you end up essentially just re-inventing the multi-junction solar cell.

Now... you could route a water line behind the PV cell, and that'd give you warmer (depends on conditions) water (and might help cool the PV cells which might help their efficiency).

Yes, but of course now you're harvesting the sensible heat, not the hot electrons. This can be useful, if you need low-grade heat.

Comment Perovskite thin films (Score 5, Informative) 42

The perovskite semiconductors here are a very different technology than the old thin photovoltaics. They have the potential to be much more efficient, and the deposition techniques are cheap and comparatively low-tech

Whether they can succeed in simultaneously be highly-efficient, resistant to degradation in the environment, and still be low cost is the subject of a lot of work. We'll see.

They were supposed to be manufactured for the price of a lollypop per square meter back in the '90s.

To be more specific, the target back in the '80s and '90s was clearly articulated as being fifty cents per watt (where "per watt" meant, when illuminated at standard conditions of 1 kW/square meter.) Silicon photovoltaics can now be purchased at 12 cents per watt. In today's dollars. They not only hit the target, they blew it away.

The reason the thin films of the '80s and '90s lost was not that they were bad, but that silicon simply outcompeted them.

So forgive my skepticism regarding new breakthroughs.

I have some amount of skepticism too. Nanosecond lifetimes of hot electrons are amazing, but to date there's no way for turning hot electrons into electrical energy*. So they'd essentially have to invent a technology from scratch.

They were designed at a price point. You get what you pay for.

How does that follow? You are treating the idea of a user upgrading their own RAM like a service RPI is providing.

RPI paid to design the board, sold them, then spent more money to make an update to prevent users from modifying a developer board in certain ways? That makes zero sense, and can only serve to alienate the very clientele that are paying their bills.
