Again, Smaller radiator = bigger heat pump + more batteries and solar panels Satellites have a mass and power budgets. Your scheme only looks at temperature. If you want to build i…

The Caltech Concept is just that — a concept. No prototype, no tests, no manufacturing, no results. When they achieve this order of magnitude improvement on a prototype scale, that…

It just goes to show magical thinking isn't just an American thing.

Ah yes. The heat pump. My response: Carnot's theorem and refridgeration cycles rear their head. Your heat pump still needs power to pump heat uphill., negating any savings from a s…

> Ok, there are at least two bad assumptions there. > First, it assumes the radiator is at the same temperature as the GPU. But radiators become dramatically more effective as temp…

This reminds me of the railgun. Basic math and physics tells us that not only would the (very expensive) barrels wear out very quickly, but that it would have had to be fitted on o…

If the "physics" tells you that your satellite cannot radiate heat away from your nVidia GPU cluster because each H100 needs 1.1 meter square of radiator, then opinions do not matt…

This borders on science fiction. 88,000-and 1-million satellite clusters (as claimed in your link) are hard to take seriously, especially with the possibility of Kessler Syndrome. …

Yes indeed, you are correct. My mistake.

The ball is not microscopic, but the tolerances required to make the ball spherical and fit into the socket are.

They do. The micro-precision subculture required to (in order): 1. Powder prep your tungsten carbide 2. Form said powder 3. Thermally prepare the resulting slurry using a vacuum fo…

It is not the pen, it is the pen tip . Ballpoint pen tips are microscopic tungsten carbide ball held inside ultra-thin steel sockets. So you need cutting tolerances precise to 0.00…

How does that change the fact that solar panels cannot be manufactured without high quality coal? (0) And doesn't that undermine the "cement for nuclear power" argument? (0) https:…

By that logic solar power should also be banned, due to the amount of coal required per panel (0) both for reduction and Czochralski process. And remember, solar panel factories do…

The LCOE may be triple, but the LFSCOE [0] (full system cost, not just cost of generation) however of solar, is triple that of nuclear in Texas, and 15x that in Germany. Notice tha…

Stupid question from a foreign newbie. What separates a code monkey from a domain expert? Can you use infosec and embedded systems as two examples please?

I see Germany now has the third highest price for industrial electricity in Europe. Why is that then?

Has Germant's Energewiende helped with solving this energy issue?

An excellent source for this architecture is Mitch Alsup and his Usenet posts going back to the late 1980s (he still posted regularly in the 2020s.)

Not only are electric trucks are unprofitable, it means you switch your dependency from Middle-Eastern fossil fuels to Chinese rare earths. At least we can make biofuels from sugar…

The overbuilding that is required for stable electricity from the sun or wind makes that a non-starter. It is no wonder that when Germany tried this, they deindustrializrd, with so…

Solar power is not infinite. Abd as long as you are using the same amount of energy/power to obtain the energy you wsnt to use, the pyshical limits of the size of the solar plant, …
