True. Good point. But that will change surprisingly rapidly. We've experienced it in Norway already. It's been a huge change over the last 5 years. I don't have a garage attached to my house, it's a shared garage build

Wait what? The nonprofit organisation thing seems very significant. That makes it fairly easy to get around if you’re just developing an app for fun, or for open source organisations to get apps distributed. So what are we left with? Apps w

There’s already a trial of CO2 capture at a trash burning facility in Oslo. I could see trash burning + CO2 capture becoming viable over time. Especially if that CO2 capture is paid for by carbon credits. (Yeah, reuse and recycle first, but

We might be running gas peaker plants in 50 years but there’s no way they will run on natural gas. The reduced scale, and gas being harder to find, will obliterate the economies of scale. We’ll be running them on hydrogen produced from exce

A lot of that isn’t unique to the west. China tore down most of its beautiful temples (the contrast between mainland and Taiwan is striking), totally obliterated any moral compass among its people, its politicians are just comically corrupt

Who cares? It's not like most of us are designing logic gate cells for chips. The transistor dimensions are irrelevant to us. I really don't understand why this keeps getting brought up. It's not even an interesting fact. Whe

If per capita means nothing, the logical solution for China is to split itself into 100 countries. Somehow that would make the contribution from each new country less important in your view. Measuring by per capita pollution and getting tha

Installed capacity is sometimes measured by power output rather than energy storage capacity. Both measures are relevant.

Most modern EVs have heat pumps. Not using heat pumps to generate heat - exploiting the larger than 100% efficiency you get in the process - offends my sensibilities. If we have propane, and want to use it for energy/heating, it’d be b

I’m not convinced that turnaround time is as big of an issue as it’s made out to be. The point of low turnaround time is to lower cost. But EV airplanes are likely to be much cheaper to operate, so they don’t need low turnaround time to be

Slower is OK if it’s faster than land based transport and can use local regional airports. Some electric planes are much more quiet when taking off. They can also be cheaper to operate. They will probably enter markets where you might drive

What makes you think a battery fire is likely at all? High quality EVs are already extremely unlikely to catch fire. Much less likely than ICE cars of similar model and age. And those cars are exposed to relatively rough conditions (acciden

That's a "yes, and" kind of thing. We can't build nuclear fast enough yet. So we need both. I'd argue that wind and solar is much more important at this point since the growth of those is now faster than nuclear has

You can look up numbers for the White-tailed eagle population around Smøla wind power plant in Norway, if you want a concrete example. You have a study there where they looked at bird deaths before and after painting a wind turbine blade bl

Stop making up non-sense that have zero basis in reality. The costs are fairly well captured in LCOE of these various sources of electricity. Questions like "How many year it lasts" is especially well captured. > How many years

Do you have any links to those studies? Because the ones I've seen indicate the exact opposite. You only need 2-3 days of storage or so at most. Tony Seba has some presentations on this topic. His argument is that renewables is getting

Look at pictures of a hydro power plant reservoir. Look at the water edge when the water level is lower. It’s like a desert. When the water level goes up and down it kills all life along the edge. That life is an important food source for f

The problem is that if they made a sub $10k vehicle now, "everyone" would buy it. That sounds great, but there's simply not enough battery factories to make the batteries for that many vehicles. The demand for expensive vehic

Of course you can move heat from something hot to something cold, it’s called a heat pump. Though yeah I get what you meant. There are heat pumps that have entered production that are designed to generate the kind of industrial levels of he

You say your last purchase was a 4yo car. A good choice for budget conscious buyers. In that case the ICE ban will not be relevant for you until 2034. Depending on what country you’re in, the ICE bans being proposed does not encompass hybri

Yeah that’s one of the aspects you need new training and equipment for. Nobody is downplaying that. But it’s pretty easy to solve now. There’s already a kind of kiddie-pool like equipment that can easily be put up around the car to keep the

It’s kind of absurd seeing some of the FUD around EVs from the perspective of li img in Norway now. We’re getting up to 20-30% of the cars ON THE ROAD being EVs now in some areas. I’d guess a quarter of my close neighbours have EVs. Accordi
