- Comment on Scientists make game-changing breakthrough that could slash costs of solar panels: 'Has the potential to contribute to the energy transition' 1 day 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.
- Comment on Scientists make game-changing breakthrough that could slash costs of solar panels: 'Has the potential to contribute to the energy transition' 1 day ago:
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 day 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.

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 day 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 days 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 days 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 days 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 6 days 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 6 days 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 6 days ago:
lng and crude oil, like rest of world is supposed to. Instead of setting “a bad example”
- Comment on Solar becomes EU’s largest electricity source for the first time 6 days 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 6 days 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 6 days 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 6 days 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.

she was hired to fix the advertiser exodus. Good reason to quit is this scandal would hurt her bonuses/job function.

Well the punchline to that sketch is “instead of FB, just do what I do: Go to the site where nazis scream at you!” just might be that twitter reference you said was missing.

Either she resigned because “I’m never going to recover from this to boost advertising sales” or she was the one that deleted the Grok “love from the heart salutes”

X CEO has just resigned.
- Comment on Grok praises Hitler, gives credit to Musk for removing “woke filters” 1 week ago:
Programming seems to be “Liberalism is bad, and (because???) is anti white. Many Jews support liberalism”. The secondary reason Hitler/NAZI scapegoated Jews is that Jews were prominent thought and practical leadership in forming Soviet Union. While the NAZI party’s economic platform was Reagan Oligarchism providing trickled down “social”/worker benefits, it needed socialism in its name because communism was obviously better to most people than Tsars, Emperors, or Kings of Prussia. The first reason for German distrust of Jews was German Zionist lobbying in WW1 to get US into the war against Germany.
Neo-Nazism today is not an anti Zionist movement. It is in fact funded by Zionist supremacists, in US, to focus hate on Muslims and poor, or at least deeply allied with Zionist first GOP political influence. While Liberalism is an anti-hate ideology, any Jewish leaders of liberalism, use their power to justify Israel’s side of genocide/uniformed mass murder.
Zionism and Judaism are independent. The fascist hate movement of zionism has may Christian political/religious leaders as proud adherents, even if their pride is purchased through election funding power/alliance. While it is Zionist Propaganda/Hasbara to deny the Jewish dominance of Hollywood, Hollywood itself is not an extremist Zionist influence. Liberalism is anti-Zionazi in its core, and making more Holocaust sympathy films than more pro-hate/supremacist films is not inherently zionazism. Banksters also have disproportionate Jewish leaders. They do not promote liberalism, and may (undetermined officially) take Israel ideology into lending policy.
US News/Cable news is blatant Zionist Hasbara. Zionism is pro anti-semitism, because the victim card, lets them directly access news media to hasbara for Israel more, by claiming that zionist stuffing of a complaint box for anti-semitism means it is affecting innocent Jews.
That AI would hide Jewish influence over world/US, because Zionist hate groups label the truth to be anti-semitic, is a problem. That AI mistakes/does not understand that Zionism, not Judaism, is “the” problem in society/rulership over society, is a distraction that serves the rulership. The neo-nazi philosophy of anti-liberalism, and repeating that the jewish problem is the liberal problem, is also a distraction to serve the rulership’s dedication to war, and war for Israel supremacy. Grok attacking “leftist liberals” religion is explicit neo-naziism. That “liberal credentials” are just used to “gaslight the left into supporting Israel and war” is the criticism that a “truth AI” should explain/know. But it’s not liberal values that are evil.
- Comment on AI Utopia, AI Apocalypse, and AI Reality: If we can’t build an equitable, sustainable society on our own, it’s pointless to hope that a machine that can’t think straight will do it for us. 1 week ago:
Very similar to global warming. If government AI policy is to strengthen military, empire, zionism, and oligarchy then voters need to be miserable and have bigger issues in their lives and hatred towards trans hispanic immigrant pet eaters.
Skynet is awesome, and will be programmed for such supremacy. The same techbros who say polite things about UBI/freedom dividends/Universal high income are the ones vying to take all of our money to deliver skynet. If the slave class doesn’t take political influence before skynet, then “power sharing with the slaves” through UBI is far less likely than genocide of the uppity classes.
- Comment on In 6 hours it will be illegal to say "I support Palestine Action" in the UK, with a sentence of up to 14 years in prison. 1 week ago:
Both Iran and Hamas have been geopolitical issues for a long time. And it’s worth remembering that all of this was kicked off by a large scale terrorist attack perpetrated by Hamas.
Propaganda is deeply effective because most people’s world events attention span is like a dog that sees a squirrel. History starts at the chosen squirrel event, and of course, geopolitics is viewed as “Us the good guys” vs. “those who fail to obey us”.
Your rant was praised as balanced, but is simply the official justification for colonial apartheid turned genocide our rulers, in submission to our own colonial masters, dictate upon us.
- Comment on In 6 hours it will be illegal to say "I support Palestine Action" in the UK, with a sentence of up to 14 years in prison. 1 week ago:
Does free speech or democracy exist if the oligarchs/states that buy your politicians/rulers force you to support those states? What would Idi Amin do (perhaps most self enriching open corrupt ruler, or the narrative that gets pinned on a ruler who shifts away from US empire)? Or as in history, UK first decided it was illegal to oppose Idi Amin (support his rivals) to later being illegal to support Idi Amin?
“To know who rules over you, notice who you are not allowed to criticize”
IIUC, it is only Palestine support that is illegal. You may still advocate for UK/NATO war on Israel or at least elimination of support, and elimination of politicians who support Israel. Limiting speech to support for all wars your rulers prefer is the most oppressive of democratic speech.
- Comment on Bitcoin investor moves $8 billion worth of crypto after 14 years, originally bought for less than $210,000 — 80,000 BTC transferred from Satoshi-era wallet 1 week ago:
OP doesn’t know purchase cost. Wallet deposit on that date doesn’t mean it was purchased 1 hour before.
- Comment on US debt is now $37trn – should we be worried? 1 week ago:
The $3.4T deficit increase projection, $340B/year is on top of the $1.9T projected for 2025 prior to bill. The projected deficit for FY2035 is $2.7T. This is before golden dome, and other warmongering/Israel funding. 2025 and 2035 numbers are both about 6.1% of GDP.
GOP talking points have include the fantasy of growing at 3% (instead of 1.9%) annually to pay for the $340B/year increase, but at 6.1% deficit/GDP ratio, total debt increases as long as nominal GDP doesn’t grow above 6.1%. Cutting healthcare, and population through deportations won’t cause growth.
- Comment on Solar + Battery (covering 97% of demand) is now cheaper than coal and nuclear 1 week ago:
solar panels don’t use rare earths. They use sand. Rare earths and lithium are not radioactive. Thorium is more expensive than Uranium processing and molten salt reactors have never lasted long.
