All these investors are expecting results on the intelligence front. And since that's a total fake sell, the expectations will inevitably crash.

My problem is not that there is slop now, it's that LLM AIs have been sold as intelligent when they aren't at all. There's even people posting on Slashdot that have tried saying AI is intelligent. Although, I haven't seen such posts of late.

Arguably, prompt engineering is a programming language. Just one less formal than usual. You only get a complex result with a complex list of instructions.

My point being there is now expectations of real intelligence. People are waiting for that servant robot to turn up. That's the real mess - It's not even close to happening as sold.

Ya, that's where the reflective coating goes. Only allow the desired band, nominally optical, through to the solar cells.

LOL, I was being loose with "polar". It is the general orbit rather than exact. You obviously understand this though, otherwise you wouldn't have nit-picked.

Which works fine with a decent differential. Funnily, there is a decent differential.

Cool, thanks.

I imagine a lot can be done to increase surface area and effectiveness of radiators, ie: protruding fins. And on the sunny side reflect unwanted spectrum so then less is absorbed as heat.

They don't make financial sense, agreed. I think this and all the other AI bros power generating proposals are not intended to be realistic. It's just for appeasing Trump.

However, on the matter of heat removal, I will point out that radiating heat works really well when the radiators are shaded from the Sun and there is a large differential from the background temperature. Funnily, there is also a need to have large areas of sunshine collecting PV panels. Some of which could be arranged to act very well as shades.

In shade the external temperature is at least below -100 C. That's more than enough to radiate a lot of heat easily. Not only that but it can done with no moving parts, and no power required to transfer it to the radiators.

A polar orbit, at any distance, can have continuous sunshine.

They're not serious proposals. It's just to appease Trump's aversion to dropping down lots more quick and cheap renewables.

It's actually easier since it doesn't need a single moving part - heat pipes to quickly transfer to radiators where, when in shade, it radiates really well.

Whether any are realistic or not, none of the proposed options from these guys are short term fixes. Certainly not this one. They're dressing up alternatives to quick and easy renewables so as to appease Trump's aversion to renewables.

Total vacuum makes convective and conductive heat transfer impossible. But it makes radiative easier. And when the background is -100 C (in shadow), radiative becomes highly effective.

There is an opportunity, for a short blackout of a few seconds, a couple of times a months - When crossing behind the Moon's shadow as the Moon orbits on the Sun side of Earth.

So there will need to be some full-load battery capacity.

When you say 50% duty ... Is that an engineering factor or are you referring to orbiting into Earth's shadow? The latter won't happen because a polar orbit can easily avoid going into Earth's shadow.

BTW: I agree with the insanity of AI spending in general. The big deployments are just doing search engine function.
