It is unfortunate because we cannot in good conscience ask people to switch from barely-processed meat to ultra-processed meat substitutes, despite the meat industry's heavy contribution to looming climate disaster. Many of us have swi

The operators of the many GW of floating PV in use seem to have solved your string problem, assuming there was any. My guess, not. Any competent engineer can design a perfectly workable utility-scale energy storage system. All that is uncer

Literally no one is actively trying to colonize anywhere off Earth. Some people lie about it when not too busy lying about other things.

If you can't get anybody to read your proof, does it demonstrate anything? Fred Moxley has (what seems to me like, but what do I know?) a nice proof of the Riemann conjecture that he got by quantizing the problem. But nobody will read

I guess this answers why you can't just try it with liquid helium: even that isn't ideal enough.

Likewise, for fusion experiments. I see assertions in planning documents that the supply of tritium on hand is wholly inadequate for planned research operations on ITER, never mind its successor imagined to be built in such a way as to be a

This seems to make claims of a shortage of plutonium for deep-space RTG power systems into lies. It seems like there is plenty of Pu for all the deep space missions we could otherwise afford.

That is encouraging. The dodgy code I see in Nheko itself must, then, be mostly UI stuff, probably coded the way dictated by Qt.

So you build out storage facilities. Whatever turns out cheapest for a given site wins. Different sites will favor different winners. We don't know yet which few of myriad choices that all work will turn out cheapest, but probably not

Alternatively, floating PV could be a lot cheaper than installing solid mounting hardware to hold panels off the ground and kept from blowing away in wind that gets under them.

No solar installation will block all of the light. Gaps between panels or rows may provide as much light as could be desired. Note, most aquatic wildlife benefits from shade, even where they depend on an algae-rooted food chain.

It should be obvious that it would be foolish to expect to meet all your power needs, including EV charging, with a small rooftop installation. Rooftop solar is to cut down on your power bill. "For a society to run on PV on scale"

People always seem to jump to the the most complicated and expensive design alternatives. A central pivot and a loop of rope around a motor capstan on-shore to gradually rotate the whole array would be obviously simpler and cheaper. The ext

What they don't tell you is that geothermal is not a growth industry because nobody sees any way to make it, or anything that needs a steam turbine to operate, competitive with wind and solar. If it were made competitive today, it woul

Unfortunately, "plant-based meat substitute" is, canonically, ultra-processed food.

Yet, Gwynne seems happy to lie about suborbital freight for him, and about colonizing Mars. I have not encountered anyone prominent at Tesla supporting his lies about self-driving (though that doesn't mean none do).

It would have cost him "only" a $B to weasel out, much less than expected losses. So it has value to him greater than those losses. Would be unsurprising if he used it for political leverage. I don't think he is allowed to ru

My bet is he bought it for the political power controlling it brings. It was cheap, if it works for that, at any loss rate.

Most people think displacing CO2 production is a much more cost-effective course than building out carbon capture. After we have deployed enough carbon-neutral energy production, we will then need to do massive carbon capture. But in the me

They seem all-over naked pointers. I even find naked "new" expressions in Quaternion. Anyway mtxclient looks different from the others. It wasn't listed among clients (neochat, nheko, quaternion) on the Wikipedia page.

Nothing in physics forbids information moving backward in time, provided it has no effect on whether the event communicated will happen after it arrives. So, information about an earthquake or asteroid strike, or even a plane crash if you d

I am starting to think it is getting time to try out Matrix again, this time with my own homeserver that won't disappear from under me like the last three services. Looking at the three C++ clients' source code, it seems all depre

They are not. Each year, more CO2 is emitted than the previous year, and the increase over the previous year is larger than last time. So, the total CO2 in the atmosphere is larger each year: positive first derivative, slope is up. The to

Let us not forget SPARC's register windows. I don't know if you could say RISC-V was optimized, as such, for undergraduate courses, but historically that was its design target. That said, there was a lot more attention to extensib

I pronounce it "riskive", myself. Had there been a RISC-IV it would have been pronounced the same, so it is lucky there wasn't one.

We usually call that "weaseling". You could say it is why CO2 emissions continue increasing at a sharply increasing rate. But presumably any behavior within an "agreement" is better than identically the same behavior wit
