Satellite signals are just weak RF signals and can be disrupted easily. There is nothing 'hardened' about them. It's funny that people think Starlink or any of its many incipient competitors are any different.

This is an incredible foretaste of what AI can enable in gaming. Not replacing humans (the creators here are former leaders from Minecraft), but rather simply unlocking more fun gameplay by offering creativity, humor, and branched storytelling customized to the player.

In addition to bi-facials starting to work quite well, HNers may be interested in a rising class of ultra-low-mass material that has come out of work at Stanford and Intel in transition-metal dichalcogenides (TMDs) (e.g. for MoS₂, WS₂, WSe₂, etc.).

It turns out these enable a very high specific-power PV cell that adds another even more attractive production curve behind what is happening in vertical bi-facials. See e.g.:

Cells are subject to aggressive binning – akin to the early days of MOS process. And specs and process capability adhesion in the industry are not as "serious" as they are in the modern, U.S.-led semiconductor industry.

Arbitrary vehicle to home/home battery/grid connection is indeed coming in very short order.

There are other products already available to do it (DCBel), and it can be hacked of course, but at the current moment everything comes with substantial corner case blind spots, mostly related to grid-forming/following switching and to the resilience of the power electronics.

You are interpreting the entire story from the perspective of the utility and ISO (which are distributors, neither a maker of energy nor a net consumer of it). They're Edison-era inventions, borne of the lumbering size, toxicity, noise, and poor capacity factor of mechanical engines.

Why don't you interpret it from the perspective of companies (which need to buy energy to do stuff) and consumers (who need to buy energy to be comfortable)? These are the actual buyers.

Then you'll see why solar and batteries win all, and utilities, with their badly potholed power highways with massive tolls to consumers, slowly reduce in importance.

No, that isn't what vaporware means. Vaporware means a technology promised, but not delivered. What it doesn't mean is a technology promised, and successfully delivered, and at the beginning of its growth curve as supply of the enabling products ramp.

By your definition, solar was vaporware in 2001 because less than 1 gigawatt per year was built. But it wasn't. It was simply early in its lifecycle. Today, 1 gigawatt of solar is installed in the world every day. Next year China will likely reach 1 TW of annual solar production capacity.

This is perhaps why software people shouldn't throw around the word "vaporware" –- a useful software-industry term –– in hardware-based industries with well developed and well understood generational patterns.

The oil companies don't own many pipelines. Pipeline companies own those. And pipeline companies are eager to do business with hydrogen companies.

The fight here is over whether natural gas-made hydrogen (SMR) is an interesting fuel at all. I think the numbers say no, while solar-made hydrogen is in fact extremely interesting.
