This clever system taps basement temps to cool your home, and now it can heat, too

New York-based Cool Down makes a thermal transfer system that moves naturally cool air from your basement into your living space while sending excess heat back down below to cool homes more efficiently. By dispersing that heat into the ground, Cool Down helps keep homes comfortable during hot summer months and cuts electricity bills in the process. more…

This 'fool's errand'

(excitedly waiting for an Automated Ignorance program to take its field in a useful new direction...)

still manages to pose an interesting conundrum

- will Displacement Aerodynamics be MORE READILY ACCEPTED by the Aero community if an AI proposes it...?

I didn't say the mania for AI is a good thing; and yes, the expense, the waste and the kafkaesque effect on information are infuriating.

But the AI is ALREADY effing itself. According to typical hype, 'the next' version is always going to do better; in reality, it only ever APPEARS to.

Hey Aileron...!

You have my sympathy; Social Media isn't the world, and it often holds up a 'magnifying glass' to some of the most troubling events out there, bringing them closer and amplifying their impact.

Spin recovery is a thing, and I wish you clear weather to aid the process...

And applying Bernoulli's Rules For Flow to the STATIONARY air a bird or aircraft flies through requires some MASSIVELY ornate mathematics

- because the idea's absolute TWADDLE...!

When air DOES flow past an aircraft's wing

(fortunately, it's a rare event...)

a VERY DANGEROUS condition develops.

This 'unreality theme park' may seem like a new phenomenon

- but in a 'manual version', it's very familiar.

Alice's Adventures in Wonderland is 160 years old, and the supposedly 'nonfiction' subject of Aerodynamics has been 'living in a dream world' for over a Century.

AI hallucinations are getting worse – and they're here to stay

An AI leaderboard suggests the newest reasoning models used in chatbots are producing less accurate results because of higher hallucination rates. Experts say the problem is bigger than that

That's the 'stepping off point' for many a Science Fiction story.

And in each, it's clear that IF "we could travel through time, space and other dimensions", then the 'mechanism'

(your 'TSOD' or John Wyndham's 'pillar and post'...)

for achieving it would also manage the relevant navigation...

The Air Whisperer @pneumofoils.bsky.social · 2d

Will that EVER happen

- without a Scientific Revolution to put 'values' ahead of 'authority' and 'hierarchy'...?

I used to see cycle couriers with all sorts of weight-saving modifications

(to their bike, that is...)

- but wearing a massive chain & padlock that would swing aggressively if a driver caused them to swerve, sometimes leading to damage...

The unfounded claim that Ground Effect combines 'reduced drag' with 'increased effective presentation angle'

(both FICTIONAL events...)

dangerously MISLEADS pilots about what's really happening when their aircraft struggles to gain speed & height

- or resists making contact with the runway.

And BOTH observations add significance to the same author's variable position on whether Ground Effect Vehicles PROPERLY qualify as a form of surface craft, or are 'obviously' a special kind of airplane.

Unfortunately, the prize's DICE ARE LOADED.

"Kitano presented the endeavour as the grand challenge for AI in science. A machine wins if it can achieve a discovery on a par with top-level human research."

But NEW ideas come from OUTSIDE THE BOX, not from massaging the egos in its 'top level'...

If we managed to set the hook with that, let Frederick Johnsen reel you in with this excellent, copiously illustrated write-up for General Aviation News. | 🛩️ | 🧵 2/2

Let the Spirit move you — General Aviation News

When you first see the Spirit Engineering SE-1, it stops you in your tracks. It conjures airplanes from an earlier era that were designed for aerodynamic efficiency that did not forget art and beauty.

Persistent Aero Myths:

'The Power of the Vortex'

In the early 20th Century, HYPNOTISM was feared; the sinister villain of a novel or movie would WHIRL something before a victim's eyes, urging them to focus keenly on the motion until everything else faded

- and their doom was sealed...!

When @theaircurrent.com was but a wee publication, we broke a huge story: It outlined how air traffic controllers had the legal authority call out sick. Those actions massively slowed some airports and ultimately ended the 2019 U.S. gov shutdown. Watch for a repeat. theaircurrent.com/aviation-saf...

Trump Administration memo opens door to mass sickout by ATC

A sharp increasing in staffing issues at ATC centers around the U.S. may signal a tipping point in the month-long partial government shutdown.

The REALLY wild thing is that air isn't even the best coolant

- it's just abundantly available in a Flight situation.

Helium's way better, and you only need a TINY thin 'film flow' of coolant bathing the parts. Even in your time, flow management is SO sophisticated that the gas can be RECOVERED...

The Air Whisperer @pneumofoils.bsky.social · 3d

I rail hard against the ignorant, superstitious and inappropriate use of Flow Mechanics to understand the NON-FLOW situation of Flight Dynamics

- but where flow REALLY IS present

(eg flame-fronts and cooling-layer 'dynamic insulation'...)

what Flow Theory enables is ABSURDLY impressive...

In any Society, there are always 'convenient fictions' that make personal interaction

(or mathematical calculation...)

easier.

But expanded to extremes, those 'white lies' can become oppressive; in Physics they regularly expand to make a mockery of Scientific 'knowledge'.

No.

Heat-resistance metallurgy has improved about 10% since 1980, when Exhaust temperatures were already WAY ABOVE the heat-limit of turbine blade materials. Meanwhile, better burn tech (eg flame-front timing...) has boosted exhaust temps by about 30%.

Yes, impossible

- except for AIR COOLING...!
