Also a clue from one of the links is that “German industrial rate customers, cost is $200k/btc”. Their industrial rate is $0.25/kwh, and so then their claim is based on 12c/kwh utility rates. Utility rates has pretty much always been cost prohibitive. Wholesales and behind the meter power is certainly an advantage large scale mining uses.

humanspiral@lemmy.cato Technology@lemmy.ml•Coin-sized nuclear 3V battery with 50-year lifespan enters mass production2·2 months agoThey use a more efficient process. Something about a diamond semiconductor that turns beta particles into electricity instead of relying on heat.
humanspiral@lemmy.cato Technology@lemmy.ml•China plans to build enormous solar array in space — and it could collect more energy in a year than 'all the oil on Earth'5·2 months agoheadline not claimed. 1 km2 as a continuous flat surface that can be pointed at sun is 250mw from commercial cells. Outside of our atmsophere, irradiance boost is only 33%. so 340mw. Geosynchronous over China will only gain up to 3 hours per day of sun. That can be a 75% boost in average daily power.
except microwave energy transmission… While a 50% efficient transmission is possible (effectively 250mw earth equivalent delivered), it needs a 100 square km receiver array. Even at 150mw per square km earth solar, is enough space for 15gw of solar.
So, it only makes sense at much larger scale, and only makes sense if denser energy costs as astronomically high as such a project. Beaming energy to other points in space, or even remotely powering a spacecraft are applications.
humanspiral@lemmy.cato Technology@lemmy.ml•Here’s All the Research Showing Your Phone Is Probably Making You Dumber5·3 months agoThis is more correlation to a peak at a date. I understand the reason to suspect phones, lower reading/long form rates. Reduced optimism about sustainability/a bright future, and financial crisis aftermath, and divisiveness, might also have a correlation to the same peak date. Or combination of these factors with widespread phone use.
humanspiral@lemmy.cato Politics@beehaw.org•The New Video of Federal Agents Ambushing a Student and Disappearing With Her Should Chill You to Your Core7·3 months agoVery evil. Some irony in that they want to make it illegal for protesters to wear masks. Past any point of return for zionist fascism in America. Too much bipartisan unity in supporting it, and then “next they will come for some others, and opposition will still say nothing.”
humanspiral@lemmy.cato Technology@beehaw.org•BYD announces charging tech that’s twice as fast as Tesla’s1·3 months agoI agree that the calculator seems to be dangerous result. Code says that 9mm 2/0 AWG copper is needed. Insulation not counted.
humanspiral@lemmy.cato Technology@beehaw.org•BYD announces charging tech that’s twice as fast as Tesla’s1·3 months agojust searched for 1000a bms’s and they don’t seem ridiculously large. unlimited length cable needs under 1cm diameter copper as code. Not crazy either. And a calculator says that 10 feet would only have 4% voltage drop at 13awg (house wire size).
humanspiral@lemmy.cato Technology@beehaw.org•BYD announces charging tech that’s twice as fast as Tesla’s4·3 months ago1mw chargers are proposed for trucking, and exist. A smaller battery being able to charge at 10C is the breakthrough. The cars on 1000v platform and 1086hp for $37300-$45000 announced… is a huge deal. I don’t think even expensive supercars have been announced at 1000v.
10C discharging has typically been reserved for small RC plane battery chemistries. LFP chemistries have supported charging at 10C but only with rapid degradation, compared to sane levels. Usual 30%-80% restrictions are likely to apply.

humanspiral@lemmy.cato Technology@lemmy.ml•China’s new silicon-free chip beats Intel with 40% more speed and 10% less energy1·3 months agoYes, I understand that more mining could be done, but what I was saying is that I don’t think it could be sustained to the level of silicon. Bismuth is a rare mineral, and 100 times more expensive than silicon.
Not an expert, but high purity bismuth seems 6x more expensive than high purity silicon. I could be wrong.
they would only be able to tackle a very small fraction of that.
It would be for ultra premium performance chips, which China has a low share currently.
humanspiral@lemmy.cato Technology@lemmy.ml•China’s new silicon-free chip beats Intel with 40% more speed and 10% less energy1·3 months agoI understand more bismuth mining would be needed to support price stability, but scale could mean lower prices. China has special needs in that innovation is required to escape US tyranny of global IP.
humanspiral@lemmy.cato World News@lemmy.ml•‘Nobody Is Safe’: Canada Sends World a Warning Against Trump3·3 months agoWest is untrustworthy towards Russia to higher level. Stopping hatred of war is first step to building trust. Somehow in 2014, Germans had enough trust to finance Nordstream 2, while simultaneously playing the Minsk accords as a delay tactic to arm Ukraine. So there is definitely a deranged mismanagement of their evil.
The obviousness to a 5 year old, is countries should side against those threatening war and extortion and not against those who do not, and whose enemy status and hatred is entirely manufactured by propaganda of your enemy.

humanspiral@lemmy.cato World News@lemmy.ml•‘Nobody Is Safe’: Canada Sends World a Warning Against Trump63·3 months agoThe pathethic loser response of amplifying losing war on Russia instead of allying with Russia is dividing and pitting allies against each other and against Mexico. Military cooperation against China interests is still amplifying. (Canada defense pact with Philippines is actually the more likely vector for war on China than Taiwan).
US overtures to Russia are tied to Israel dominance. Disarming Iran in exchange for pacifying Ukraine.
Extremely simple coordinated policy is to ensure US made cars go up $10k+ in cost. Export tariffs on materials and Canadian energy, matched by Europe. No manufacturing in US, no US weapons purchases. Kill Boeing, Caterpillar, Deere exports. Destroy US agriculture competitiveness with Canadian Potash export tariffs. Get Asian colonies on board by flirting with North Korea, including using them as a nuclear shield.
No one was ever safe from US. The pathethic losers who chose sycophancy to US empire, still have the choice to stop being oppressed losers. That path is not through half measures of believing propaganda on accepting the US’s enemies as its own, and their 5th column traitors that keep repeating the propaganda.
