The comparison is perhaps with a private yacht. And can I live aboard permanently on a siding somewhere? The local cement works has a siding... Hmm

I'm tied and bored, and read the whole thing. The sponsor is an AI service provider - did I get that right? So, is the article AI generated? It certainly has all the hall marks.

This article appeared on HN a while ago. https://dynomight.net/more-chess/ It basically is in agreement with this article and provides a few more trials and explanations.

No mention of lightening! The idea that the triboelectric series is more guidelines than rules was interesting, but the metal-insulator distinction seems a bit off. Is there a triboelectric effect between two conductors? How? Why wouldn't the distribution of electrons even out in a pair of conductors, or do they mean non conducting metals? And I imagine someone has looked at triboelectric effects between crystals of varying materials - does anyone know?

This type of fuel basically cant melt so with no helium it would just heat up and natural convection would cool it.

And everything around it? It is quite a challenge to design something that can do that.

Counterpoint: we've been powering ships with microreactors for decades.

Yep. And the Russians have had pluggable nuclear power for years now.. on barges: wikipedia.org/wiki/Akademik_Lomonosov Decommissioning no doubt will consist of scuttling them over a trench. Definitely going to wake the Kraken.

Looks aspirational to me. 1Mw electricity at 30-100% efficiency (100??) and 1.9 Mw heat via air in the volume of a shipping container? That's moving a lot of air. And I'd want fail safe, passive control "rods" (what happens if the helium leaks out and the heat isn't being removed) before I'd sleep easy with one in my back yard.

Loebner (of the prize fame) patented the idea of a rollercoaster tube system. Stations on the surface, going underground and up to the next station. Saves power and reduces the curb to platform time. Just thought I'd put that out there...

As a leftie - admittedly one who thinks - I thought the article was actually quite positive and didn't bring politics into it: "What would that look like for something as simple as EV charging stations? Standardized approval processes. Pre-approved vendor lists. Streamlined permitting for routine infrastructure. Clear timelines with accountability mechanisms." A clear and sensible suggestion. Cool.

I liked the blog post. I try not to "game the system" and usually get all judgemental about people who do. Okay I am old fashioned. Putting on my Gordon Gecko hat ("greed is good"), of course, it is the disparity between system reaction times that enables gaming it. What system can one develop to get inside an adversary's OODA Loop (observe, orient, decide, and act). I like the idea that it's a (meta)system problem, it's about leverage.
