  Well, there is some data/rumours out there, stemming from a Dutch Tesla forum, that suggests that some fast charging might be beneficial for battery longevity. This seems to corroborate that. I can’t remember the case for always fast charging, though.

  That’s an accurate name for the new toy, but not as fancy as “ai”, i guess. Because we know that anything that comes out is gibberish made up to look like something intelligent.

• ⁨Comment⁩ on ⁨The quest to fix the irony at the heart of every heat pump⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:

  Same here. At work we are using CO2 for fridges and the line as a stop gap where its possible, but for smaller units we are looking at a lot of substitution…

  Very interesting. Does anyone know if any of these solutions allow scale up?

  You mean to say that Facebook isn’t the main distraction of the -10s? Before Facebook it was TV that was the circus and low prices and no/hidden VAT provided the bread.

  Unfortunately i think it’s the same old extortion we’ve seen before. Trump Jr already posted “I wouldn’t want to be the last country to cut a deal”, so I guess we will see more if this. Ukraine stood up against it, I hope the rest of the world does to, but I’m afraid most wount.

• ⁨Comment⁩ on ⁨Bernstein Posits That A 10 Percent Baseline US Tariff On Raw Semiconductors Is "Not Going To Do All That Much," But PCs, Servers, And Smartphones Are About To Get Pricier By ~40 Percent⁩ ⁨⁨3⁩ ⁨weeks⁩ ago⁩:

  I don’t know how we define “enough” in this scenario, but as you allude to: in the end the USA is just some 400 million people buying things from overseas. Absolutely those who buy the most, and that is what drives the economy in many countries. It is what has picked up countries in SE Asia from poverty to industrialization.

  Problem is that now when everything is more expensive in the US, the same people will stop spending. They might have spent the same money on products made in America, but those are precious few and just increased in price. So in effect everyone in America can now buy less for the same money and the industry capacity to produce what’s demanded doesn’t exist in short term. And in real estate, short term is 3-10 years.

  The rest of the world? Well, most of the world just lost their biggest market. Of course, the demand that can’t be produced domestically will still be seen, but at a reduced rate, which will reduce the economic development world wide, until new markers are found. China still needs to sell, but the market for the high margin stuff is reduced.

  In the end? I wouldn’t be surprised if this stunt reduces world trade to such a degree it might be viewed as a notable side effect that carbon use went down. Trump might have managed to stop overconsumption like nobody else and with it energy demand. So despite doing the oil industries bidding and go against renewables, the shipping industry stand to loose enough trade that it might affect oil use world wide.

  Inflation is defined as the increase of prices over a set period of time. It is in itself nothing, doesn’t do anything and its singular purpose is to be able to say how much something costs today compared to yesteryear. If the price difference depends on a supply chock (something that affects the ability to produce, like a shortage), or a demand chock (suddenly everbody rejects Tesla) is all the same, it results in a price change and can therefore be compared using the measure inflation.

  The internet as we know it is dead, we just need a few more years to realise it. And I’m afraid that telecommunications will be going the same way, when no-one can trust that anyone is who they say anymore.

  As you have described the situation my question is if it would be similar to copyright Donald duck, despite not having drawn all possible poses and situations?

• ⁨Comment⁩ on ⁨Scientists for Future, October 2021: Nuclear Energy is no technology for solving the Climate Crisis⁩ ⁨⁨1⁩ ⁨month⁩ ago⁩:

  Oh, by all means. Build nuclear to your heart’s delight, but in the meantime we need to build wind, solar and water as well.

  The part that annoys me the most are the ones that think that it is either or. It’s not. It’s as much as possible as fast as possible to replace as much fossil in total volume as possible.

• ⁨Comment⁩ on ⁨7 reasons why nuclear energy is not the answer to solve climate change⁩ ⁨⁨1⁩ ⁨month⁩ ago⁩:

  Or we skip to the obvious conclusion:

  Tio little, too late.

  It will take too long to implement and will not solve the energy need when it is done. And it will cost more than anyone wants to pay.

  Pushing nuclear, is just a strategy to obfuscate the discussion and prolong the life of oil infrastructure.

• ⁨Comment⁩ on ⁨Countries across the world use more land for golf courses than wind or solar energy⁩ ⁨⁨1⁩ ⁨month⁩ ago⁩:

  Absolutely, I’m not US and I have no experience with megacities, but I am trying to find ways to build cities that better match our needs going forward. I don’t know if the American car dependent suburbia is what is needed either. As for parks in dense cityscapes, I’ve listened to clever architects who’ve discovered statistical regression claim that parks are more valuable per square meter the smaller they are… And while true in and of itself, it asks the question, how small is the minimum for them to be usable? Humans that experience greenery (even arranged) daily are healthier both mentally and physically. Where is the cut off?

• ⁨Comment⁩ on ⁨Countries across the world use more land for golf courses than wind or solar energy⁩ ⁨⁨1⁩ ⁨month⁩ ago⁩:

  Ouch. And how many of those are children?

• ⁨Comment⁩ on ⁨Terraform Industries actually created synthetic methane from sunlight, water, and air⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

  I have the excess electricity already, but I’m not yet at the legally required amount of solar panels.

  I’m investing in energy storage, both batteries and heat storage and looking for more solutions.

  I’m looking at hydrogen, because it’s known tech and I dream of finding a way to use it in a more stable chemical form for storage.

  This is very interesting! And that fuel could be used either to make electricity, heat or a combination!

• ⁨Comment⁩ on ⁨China renewables capacity additions soared in 2023, growing more than four times faster than the G7⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

  I agree that energy security and geopolitical considerations are behind China’s all out expansion, I’ve said so before, but in this particular case, I wonder if you might have overlooked an implied /s?

• ⁨Comment⁩ on ⁨Why are energy bills going up, if there is more green power? - BBC News⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

  Yeah. Someone will always be able to pay more than the common man. And companies using it to produce something will always afford to pay more than someone just consuming electricity.

• ⁨Comment⁩ on ⁨Why are energy bills going up, if there is more green power? - BBC News⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

  You are so right. Thank you! In a situation where it is impossible to generate or import any electricity at all, a nuclear reactor would not be able to produce any electricity either, because the grid is non-operational.

• ⁨Comment⁩ on ⁨US‘s wind and solar will generate more power than coal in 2024⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

  Which, in the end will make a “no renewables”-stance untenable, since renewables are the only way of growing the energy sector fast enough.

• ⁨Comment⁩ on ⁨China installed 8 GW of solar in ‘Belt and Road’ countries in 2024⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

  No, not at all. Pure geopolitcs. In this case a double win, where china ties these countries closer to itself through investment and electricity produced west of China can benefit china directly after sundown.

  This is how the long game is played.

• ⁨Comment⁩ on ⁨Norway on track to be first to go all-electric⁩ ⁨⁨3⁩ ⁨months⁩ ago⁩:

  Not surprising. Norway seems to be driving a lot of development away from excess energy use and oil. Not only in transportation, but also in real estate.

  I know little of all projects there, but what I do know makes me want to go there and learn how to do better. When (not if) electric uptake nears 100%, like in Norway, things will start to happen in the market. Petrol stations, refineries etc. will see a very different demand, which will propel much needed change!

• ⁨Comment⁩ on ⁨Fossil Fuel Interests Ramp Up Their “Solar Makes Electricity More Expensive” Falsehood⁩ ⁨⁨3⁩ ⁨months⁩ ago⁩:

  North Sea oil is called Brent and wti is an American oil. Short for West Texas Intermediate.

• ⁨Comment⁩ on ⁨Fossil Fuel Interests Ramp Up Their “Solar Makes Electricity More Expensive” Falsehood⁩ ⁨⁨3⁩ ⁨months⁩ ago⁩:

  They are also more desperate. US oil needs the price to stay above 50$/barrel, and the price of WTI had been in decline for the last 3 years, trending downwards. These are desperate plees for help from an industry backed into a corner.

• ⁨Comment⁩ on ⁨Dark Doldrums Overshadow Europe’s Energy Markets | Periods of low sun and wind, a weather pattern known as a Dunkelflaute, can increase electricity prices and stoke political tensions.⁩ ⁨⁨3⁩ ⁨months⁩ ago⁩:

  In a way, EUs fit-for-55 already lays out a plan for this. By demanding solar panels on all civic buildings in the union, solar production from the Mediterranean countries will provide an electricity boost during these spells.

  For the northern countries and eastern countries, the demand for renewable energy sources in the district heating will push prices and incentivies development and other heating sources, like thermal storage, or other storage solutions, like hydrogen. In the short term, even batteries storing nuclear and hydro power from night to day time will make a huge difference.

  But in the end: we need more storage!

• ⁨Comment⁩ on ⁨Baseload power generators not needed to guarantee supply, say science and engineering academies⁩ ⁨⁨4⁩ ⁨months⁩ ago⁩:

  Well, demand is low, supply is little and inefficiency in production is high. With that said, EUs fit for 55 will soon provide plenty of solar power, so summer days will see practically limitless electricity. At least enough to brute force the inefficiencies. maybe then.

• ⁨Comment⁩ on ⁨A surprise solar boom reveals a fatal flaw in our climate change projections⁩ ⁨⁨4⁩ ⁨months⁩ ago⁩:

  Yeah, don’t get this idea that everyone else will be somehow better than the western world if given the chance. People are people no matter where we live. We are about equally lazy on average and the ability to pay for power is down to circumstances.

• ⁨Comment⁩ on ⁨Battery Electric Vehicles still being shunned by EU buyers⁩ ⁨⁨4⁩ ⁨months⁩ ago⁩:

  Long haulers usually prefer to gas up at their own private facilities to keep costs down, as I’ve understood it, using gas stations more as an emergency refilling. I’m not sure if that market is big enough to carry the entire infrastructure itself.

  Construction is another big sector for diesel, but in both transport and construction there is a lot of work being put into moving the sector to electrification. Which is well, because given how fast the automotive market has turned change might be fairly quick.

  There are other uses as well, but will they be able to carry the market? Driving the need for supertankers and trillions worth of investment in oil infrastructure with fuel cans at the chemistry shops? With rising production costs for big oil? I don’t know if I’m more relieved or more anxious about the idea…

• ⁨Comment⁩ on ⁨Battery Electric Vehicles still being shunned by EU buyers⁩ ⁨⁨4⁩ ⁨months⁩ ago⁩:

  Well, I may be cynical, but I’m asking two questions:

  1. Who owns media?
  2. What happens in a society when EV reach 90-95% market share? What happen when the last petrol station goes bust? Which infrastructure will follow?

  I see a huge interest in not letting incumbent infrastructure fail. That’s what electrification is up against
