And fusion doesn’t work yet. May be 20+ years away for 20+ more years.
- Comment on Startup Claims Its Fusion Reactor Concept Can Turn Cheap Mercury Into Gold 12 hours ago:
5 metric tons of gold created per GWh of electricity
per GW. 5000kg over whole year of 1gw reactor going almost continuous. While there is no theoretical possiblity of creating economically viable fusion energy, a minimum reactor size would be 10gw. Needs 1gw of backup fusion to provide stable power input, and make the deuterium.
$500M/gw in gold revenue could make a difference in the economics. If fusion cost 2x what fission costs per gw, ($30/w) then it would make back its cost in gold only over 60 years, @$100/gram.
- Comment on New Executive Order:AI must agree on the Administration views on Sex,Race, cant mention what they deem to be Critical Race Theory,Unconscious Bias,Intersectionality,Systemic Racism or "Transgenderism 3 days ago:
Best definition of humanism is defining good, but only forbidding evil. Everyone has the freedom to not maximize good, as long as they don’t hurt orhers. This is what is needed for ai. Otherwise it is just as oppressive as traditional media.
Surely, for hiring, best candidate rather than social work culture is ideal, but for private enterprise, maximizing non evil ( Say zionist or other supremacism,purity) cultural priorities might be important instead of technical prowess. University includion is good because it is a social experience instead of pure automaton factory.
While exclusion is evil, inclusion also may not choose best candidates and so is also evil. Inclusion is not the same as no exclusions.
In the end, nepotism is the grey area of humanism. Certainly, an employer can choose any bias they prefer. You can teach them that best candidate is best, but their freedom matters too. Buy american,/nationalism can have some merit in that what you buy directly improves lives of a tighter social group to you than the indirect flow of globalized profits into homes, exports, and national debt values. You can teach nepotism is bad for you, but you cannot morally force either in group or out group trade.
- Comment on 6G mobile could divide the world 1 week ago:
National dominance of technology is bad for people, because Sovereigns want control and slavery over people. People benefit from cheap tech advance access, without any trickle down from the nationality of who profits.
5g equipment is all made in China, regardless of parent company ownership. There is no, afaik, extra surveillance powers compared to 4g equipment. Much of the speed/latency boosts of 5g futurism applications remains unpenetrated.
Instead of pretending that national security is for benefit of national subjects, communications protocols should focus on end to end encryption with supporting hardware, and include middleware encryption/decryption to add controlled layers to protect privacy additionally from rival intelligence interests.
In the end, consumers need to trust google or apple to some level, but open source, and different open source applications on top of the OS.
This outcome is impossible when CIA and other intelligence agencies are part of the standards process influence, but technical only protocols that ignore the oppression by default political context, support the oppression by default standards process.

Japan is not known for having any/many immigrants, as it is. Expats generally avoid it for high cost of living.
- Comment on Solar powered personal umbrella with battery? 1 week ago:
It’s a better product idea than you make out.
It does require industrial design, and tooling for flexible panel manufacturers to make umbrella patterned panels, as cheaply as rectangular patterned ones.
Flexible panells top out closer to 25% efficiency than 20%. 200-250w is a lot of power. The umbrella itself needs just a hook for a battery rather than coming with one. Solar or USB (up to 240w at 48v power) interfaces. This can power a mini pc with a couple of large monitors with power left over. 1kwh per day/m^2^ is enogh to cover a high power laptop, electric cooking, or if it were a beach parasol, keep a drink fridge cool, and boom box TF out of the place. Because you need an ebike to lug all of the crap to the beach, it can charge it back up. Besides beach use, a parasol would allow supplementary power for van/RV or even a house, when not beach party boomboxing.

- Comment on Scientists make game-changing breakthrough that could slash costs of solar panels: 'Has the potential to contribute to the energy transition' 1 week ago:
You’re right about US. seems half uses tracking. No numbers on China which is 30x larger market. Economics still only make sense at consumer level of $1/watt panel prices, to me, but I guess there are reasons I don’t understand.

OP is the one that made comparison. Terrorism gets more attention if victim is oligarch.

It’s viable as edge of day high power boost in east/west direction, and simply any extra power that is cheap and easy to install, that adds privacy or keeps the controlled beings inside.
- Comment on We are living in the Pre-"Drone 9/11" era. 1 week ago:
3000 killed and $1T property damage/rescue expenses in a day doesn’t need to be matched by drones to make an impact. A single, Luigi style, untraceable, car or house impact, would make the oligarchy apoplectic.
- Comment on Scientists make game-changing breakthrough that could slash costs of solar panels: 'Has the potential to contribute to the energy transition' 1 week ago:
The cells are super expensive but super small. They need cooling for efficiency, but if the heat moving is useful, can ignore the energy cost.
- Comment on Scientists make game-changing breakthrough that could slash costs of solar panels: 'Has the potential to contribute to the energy transition' 1 week ago:
I think their approach with module is 20-50x concentration instead of 500x, with cooling permitted to be module wide on air gap, as well as usual bottom cooling.

wouldn’t diffuse light be what it’s going to be best at? While it’d be worse on a sunny day when there is an optimal single direction for the light to come in?
No. Concentrated solar requires perfect alignment, dual axis tracking, to the sun. diffuse light does not concentrate.
A reasonable alternative design would be cheap ordinary PV cells with outward bubbles instead of inverted parabolas that would capture off axis light better on a fixed tilt.

This is 36% MODULE efficiency with expensive cooling. 30% actual year long efficiency without it. Requires dual axis tracking. Seems heavy as its very tall/deep.
Headline of cost reduction is very unlikely. Especially on a per acre/fairly large area basis. Dual axis tracking requires more spacing than fixed orientation rows, and loses benefits under cloudy conditions. While power at 7am and 5pm is more valuable when competing against high penetration solar, batteries are now more competitive than tracking, and can serve edge of day and night power needs. Tracking solar tends not to be built anymore, due to low cost of panels. The cooling infrastructure is also not as useful as it is on rooftops because the heat capture has useful benefits for homes.
It is also unclear how this has advantage over parabolic mirror.
Agri PV is a real use case, where more free land means more land use, even if most of it gets more shade, except around noon.
- Comment on EU warns that its trade with the US could be effectively wiped out if Trump follows through on his threat 2 weeks ago:
Solution is obvious. Just spend 5% of GDP on US weapons, and give US tech tax free access to skynet spying on its citizens. Promise war on Russia to increase the dependency. 30% tariffs is actually the reward for this subservience.
- Comment on How come nobody does anything about North Korea? 2 weeks ago:
Holy hilarious nerve hitting, Batman. Superman is the American way/might that simplistically pretends to side with truth and justice.
- Comment on How come nobody does anything about North Korea? 2 weeks ago:
We all see and hear what goes on over there
First, the ROK unfiltered propaganda on DPRK is as believable as Ukrainian propaganda. We all know “the pure unvarnished truth” as the complete trust in that propaganda.
The US’s unjustified war on Korea was to overthrow a democratic unification election in which the less corrupt North party won. Ever since, an oligarchist duopoly has been propped up by the US, and standard of living is determined by the isolationism imposed by US/ROK alliance.
DPRK is aligned with winning future alliance, and ROK is being canibalized, like other colonies, by its master. DPRK has always been the stronger military side, by necessity, and the future is likely better for them. In your example, “why not do something about the US for actual verified first hand threats to citizens not cheering enough for Trump”?
- Comment on Solar becomes EU’s largest electricity source for the first time 2 weeks ago:
The reason for liars to lie about Spain is to bully/disinform rest of Europe and US public into going harder on FFs.
- Comment on Solar becomes EU’s largest electricity source for the first time 2 weeks ago:
Europe has regularly imported oil from US even as it gets most of it from US/Israel middle east allies that easily replaced Russian supplies. Upon submitting to the US’s proxy war on Russia through Ukraine, NG prices in EU spiked and it got 50% of its supplies in 2022 from US LNG. The US’s determination for climate destruction requires pigfuckers telling EU that renewables don’t work, and it should depend on US energy supplies instead.
- Comment on Solar becomes EU’s largest electricity source for the first time 2 weeks ago:

US administration does have a vendetta against renewables, and failure to buy US energy at extortion prices.
- Comment on Solar becomes EU’s largest electricity source for the first time 2 weeks ago:
US disinformation pigfuckers claimed it was due to intermittent power. No such conclusions were ever made, and there is no physical/tech challenge/impossibility to not have a stable grid with intermittent power.
- Comment on Solar becomes EU’s largest electricity source for the first time 2 weeks ago:
The wrong analysis for energy transition involves proposals to nuke energy sources from orbit followed by a transition. Italy has still managed 14% NG reduction in April. I understand little heating in the month, though. Heat pump efficiency in Italy can be well over 600% due to mild winters, and double as AC. Energy transition analysis is simple. Add solar, worry about NG electrict utility tears later. This also reduces market prices of NG, for those who don’t switch.
- Comment on Solar becomes EU’s largest electricity source for the first time 2 weeks ago:
6.1 per cent of EU electricity came from coal, down from 8.8 per cent a year earlier
about a 30% reduction
with all of the US hopium on LNG export infrastructure, Europe cut gas use by 15% in April relative to 2024. 2024 also saw 10% NG reduction, and15% coal reduction. Conservative LNG import forecasts are a drop of only 25% by 2030, instead of a solid 10%+/year drop continuing.
