They have broken ground. SPARC is well under construction. ARC is going to break ground soon. Which is why I said 5-10, not 5.

Unlikely because its magnets suck by modern standards and so it canâ(TM)t reach very high pressures. SPARC/ARC might do it though. And yes, we absolutely will have commercial fusion in 20 years. Likely more like 5-10.
Fusion needs three things to work:
- A âoehighâ density of plasma (high is relative, in reality itâ(TM)s close to a vacuum)
- A high temperature (not relative, literally the hottest things in the solar system)
- A long time at those conditions.
The higher you make the product of those three the more fusion you get and the more energy you get.
At the same time though, you need to stop your fusing stuff from touching the outside of your reactor, because itâ(TM)s incredibly high temperature and radioactivity will destroy the reactor. It will also rapidly cool the reaction, shutting it down. That means you need to be really good at containing the hot plasma in the middle of the reactor.
These reactors do this by using magnets to squeeze the plasma into the middle (increasing the density), and various forms of heating to get to the desired temperatures. However, when you squeeze the plasma, it wriggles around like an eel trying to escape. At some point when you try to grip it too hard, the eel just slips straight out and shoots across the reactor into the walls. That limits the size of the product described at the start, and so limits the amount of power you can get out.
These scientists have discovered that if youâ(TM)re very careful about how you position the eel when you start squeezing you can squeeze a lot harder before it starts wriggling about like crazy.
Also, where do I sit as a fat person? Itâ(TM)s generally considered pretty impolite for me to take an economy seat and then overflow into neighbours space, so I get business seats to have enough space for a more ⦠uhh⦠generously proportioned human.
Where do I sit as someone who has severe restless leg thatâ(TM)s badly exacerbated by sitting in the exact same position for hours, and results in me repeatedly kicking the person in front of me?
Where do I sit as an old person who canâ(TM)t stagger down the incredibly narrow aisle for the length of the aircraft and then get over a bunch of fixed handrails?
Where do I sit as someone whose pelvis is in a cast that canâ(TM)t fit into an economy seat?
Thereâ(TM)s a ton of reasons for booking business class that arenâ(TM)t just that work are paying for the ticket.
And yet, we have concrete evidence that isreal continued to expand into palestinian territory during this time, fueling Hamas, and encouraging the terrorism. Stop trying to make bullshit claims that Isreal is somehow clean in this situation.
Ah yes, killing about 100 civilians (a disgusting attack, that should never have happened), deserves a genocide of literal millions, thatâ(TM)s a proportionate and reasonable response.
The crazy thing is that the price increases have already made Appleâ(TM)s infamously ludicrous upgrade pricing seem reasonable. Apple want £400 for 32GB. A couple of months ago, that was 4 times over the going rate. Now itâ(TM)s pretty much normal. The cheepest DDR5 6000 on newegg is £330, and higher bandwidth stuff costs of the order of £5-600. (And thatâ(TM)s ignoring that Appleâ(TM)s on chip RAM is anywhere between 50% faster and 300% faster than high end DDR5 depending on the chip).
Because youâ(TM)re a nerd probably. That said, the article seems to motivate things rather poorly.
I donâ(TM)t get how anyone would ever expect this to be cheep though. The reason RAM is expensive is because the production capacity for chips is being used to produce GPU RAM for AI data centres, not because thereâ(TM)s some disconnect between chip prices and DIMM prices. Buying the chips is going to be just as expensive, because the chips, and production capacity are needed elsewhere. Whatâ(TM)s most likely to happen here is that you get a bunch of chips that failed QA and then leaked out to the (dark) grey market Chinese sellers.
Recent studies suggest that it does not have anywhere near as much acid in its atmosphere as we thought, especially in the upper atmosphere where heâ(TM)s talking about.
For the quick version of why you donâ(TM)t want WiFi security cameras - itâ(TM)s a very common approach already for burglars to use to fire up a WiFi jammer as they go in. You end up with your security cameras dropping out exactly when you need them.
Yes, but then until it crashed because of completely not cosmic ray related issues, ingenuity used off the shelf computers, and on the ISS you will find bog standard modern computers for the astronauts to process data on.
Yup, I'm sure they haven't thought about this issue at all when considering putting computers in space.
With your solution, all a thief must do is unplug the receiver, or wrap it in tin foil, and theyâ(TM)re home free.
No, it's never meant that.
In the UK, million has always meant 10^6. Milliard has always meant 10^9, but has fallen out of favor. Billion used to mean 10^12, but now usually means 10^9. Billiard has always meant 10^15, Trillion used to mean 10^18, and now usually means 10^12.
I mean, as long as they continue to bill uncle sam less than their competitors, i'm fine with this.
