I have an old voffee mug covered with 1970s computing aphorisms. One says, "If computers ever get too powerful, organize them into a committee. That will do them in.."

Yup, one stated reason for the RAT on documents I have seen is to extend the data collection by the FDRs by maintaining power to the sensors and canbuses.

That's how I read it. It should say it has no thrust.

A typical jet turbofan airframe has two engines that each have a generator shaft taking turbine energy and making electrical current. It then has a whole 'nother turbine engine used on the ground and in some other flight legs called the APU; this exhausts out the tail cone usually, and can start engines or provide extra hydraulic power if needed, but is slow to start just like the main engines.

For power loss emergencies, a small spring-loaded fan pops into action super fast, called a Ram Air Turbine or RAT. It can only make enough electrical power to reboot key systems like engine FADECs or avionics, often only on one electrical channel instead of all channels. It's only a turbine, not a thrust-producing fan. It's a pinwheel toy in comparison to the APU and even the APU cannot produce significant thrust.

Their population absolutely dwarfs Canada and the US as well, so that isn't much good, is it?

BTW, remember the secret of Ti Kwon Leap- Anger is a weapon only to one's opponent.

I still think we need, given the microamps involved, a hamster powered cell phone charger.

Yes it is. Radioactive materials are made in the planet's core, and float up in the magma. Radon Gas is a normal and natural resource from decaying uranium.

It's as renewable as sunlight and wind.

Difficult is not equal to impossible. Heat can be used to boil working fluids, which can be used to drive turbines, which can create energy, which can in turn be used to run AI chips, which give off heat, which can then also be harvested to boil working fluids...Not really a perpetual motion machine, but the inefficiency in the system can be used to suck more heat out of the heat pumps anyway. Inefficiency in this case is a feature.

My answer to environmentalists claiming this is "You first". Stop being hypocrites, eliminate your own fossil fuel usage- including wasting fossil fuels storing articles like this in data centers.

Would this be the same China that is building coal fired plants at a rate of 95MW a year?

Nuclear power is a renewable.

Fission and fusion are replacements, carbon free.

Not the solution. Heat is energy. Energy is needed to feed AI. The clear solution is to figure out how to harvest heat directly, cooling the planet by feeding heat to data centers as electricity.

What we need is a 2nd study, using 400 students, separated into four groups:
1. Using Google ONLY by looking at the 3rd page of results (the first two pages are now taken up with Gemini AI and targeted advertising).
2. Using ChatGPT Only.
3. Using inventory computers in a large metropolitan library
4. Using old fashioned card catalogs and books.

I wonder if we chose a significantly esoteric subject, with a 100 question exam given after a week, if any useful clustering could be detected.

" could seep upward into the Alsace aquifer," implies that the aquifer is *above* the depth of the mine. So the question becomes, what is this magical mine where gravity works backwards?

Where on the planet is not near groundwater?
