If you remove the volatile keyword on variables/attributes how do you ensure that a variable that needs to be accessed with volatile read/write always uses such intrinsics? Seems to me that you want to keep the keyword but give a

Most fast charging stations can’t do 800V ultra fast charging anyway. Even here in Norway, in the region of the world with one of the highest densities of fast charges, I had to actively hunt around to find a charger that could take my Hyun

Even Chinese companies are moving their manufacturing out to countries like Mexico and Vietnam. Samsung has moved all their manufacturing out of China. China themselves do not want to get stuck just doing manufacturing. Though I suspect in

That’s just categorically false. China needs US companies for their survival. They have neither food security nor energy independence, and the they’re critically dependent on American companies in several aspects of those areas. You can’t j

I think this will be solved by decarbonisation of heat intensive industries. There’s some very good thermal storage battery solutions now, that can store thermal energy at hundreds of degrees C for a very long time. So once there’s enough o

USA never thought, or even wanted to block the sale of Russian oil completely. That would raise global oil prices too much, which would be political suicide, and a problem for the world economy. The only point of the sanctions is to make Ru

I don’t know which HNers you’re thinking about. But the only supposed mechanism I’ve heard of why sugar makes you fat is that it affects insulin, and insulin is the mechanism that signals fat cells to store fat. I haven’t heard/read an

The bit caveat here is that most of the progress has been in a few areas along the coast. A majority of Chinese are still very poor and not really seeing the benefit of this technology. Even the wealthiest provinces of China have lower GDP&

Thread link: https://threadreaderapp.com/thread/1777819087357481316.html I find the argument about how bad electricity is extremely unconvincing. It’s very clear that EVs will eventually match or even surpass ICE cars

What Samo Burja is saying in this video is what worries me about some nuclear proponents: they seem to think if we just bet heavily on nuclear we can make 10x, 100x, even 1000x as much energy without any limits on growth. But thermal power

I don’t think you can use history as a guide here, because this is the first time in history we have inverted population pyramids as far as I know. The only parallel is Russias invasion of Ukraine. But there’s a huge difference: Russia is m

If we’re talking about knowing existing facts about the world, absolutely. They’re also better than most of us at creating art (rhymes, poetry, digital paintings, etc) that falls into existing clearly defined patterns. But when it comes to

This U curve is super interesting to me because it confirms an impression I’ve had that everyone I know with higher education and salary is having at least 2 kids unless there’s something serious preventing it. Here’s my recipe for getting

Gasoline fuel infrastructure is heavily reliant on the electric grid to operate. It wouldn’t operate at any significant scale without it. EVs can be paired with solar panels to be completely independent of the grid for many years. “Radical”

You might overestimate the demands on the grid. For Norway in particular it’s been calculated that everyone can drive EVs without any upgrades to the grid, if smart charging is implemented. That means having a smart meter that charges you t

If you actually use the batttery for daily driving, smaller battery means you have many more battery cycles for a given distance, meaning the battery degrades faster. I’ve been in favour of EVs or plugins with small batteries myself. But in

I’m convinced that thermal power plants in general are very problematic in the coming decades. I think you can ignore the insane challenges of maintaining the plasma itself and just consider the heat energy, the volumetric density of the po

I don’t think the political factor is as big as you’d think. Norway is an oil country and has a really high share of climate skeptics. Yet EVs are selling very well. I think most people will drop their political objections to EVs the moment

But a car is one area where “trickle down” actually works. If you want to get affordable second hand energy efficient EVs into the market.. someone has to buy new EVs. Now. Preferably as many as possible. We’re also rapidly heading towards

What happened is that a vast quantity of people moved into and around the cities. We also have more strict building codes that take into account light, air quality, longevity, energy effiency etc. You’re looking at an old city built for a r

Kind of sounds like Verilog. Not that Verilog would be suitable for anything but RTL simulation/implementation and analog circuit models.

You've glossed over so many things. The banks are not just in the business of lending out money. They also take deposits and pay interest on those deposits. It's a fraction of what they make on loan interest payments, but it'

Are you sure your intuition about wireless charging for EVs is correct? Bjørn Nyland did a test of a wireless charging system vs a wired charging station, measuring at the power input to the charging station. If I remember correctly the wir
