I'm optimistic that the rise in geothermal will be astronomical once it gets off the ground. Both advanced and more simple conventional for district heating. We're at most 10 years from the confidence in oil and gas investments be

As already pointed out I think the parent post was sarcastic. But the tire dust problem isn’t inherent to EVs. There are EV fleet owners that report a very similar tire wear with their ICEVs and EVs. It depends on what model you have. EVs c

Your personal impression doesn't really matter though. What matters is the statistics. Of course there is sun in Germany. Yes, there's less. But then it's also cooler which makes the solar panels more efficient. What matters

In the north thermal energy storage is a viable solution, and those can store energy for months. You can dump heat into them in summer and still pull from it in winter. Since heating is by far the biggest consumer of energy in winter, just

There’s reasons nuclear plants has always been built as huge monolithic structures. Power production scales with containment vessel volume, but many of the costs scale with the area. It’s inherently cheaper to build big. Small modular react

In a place like an airport, since the infrastructure is completely fixed and used every day, it’d be quite easy to do a battery swapping solution. Would potentially be faster than filling gas.

Nuclear is arguably only safe due to those regulations. The case of falsified certificates in Korea shows that you need plenty of margins to account for some of the regulations not being followed properly, even in a first world country. May

I'm dreaming that someone will remake Connections some day. The quality of the recordings are quite bad, and while I think retelling the stories with a new production would be great in itself, I'm sure there's many new storie

How much less efficient are they exactly? I wish the article mentioned that. Is the lower efficiency partly offset by the panels not getting as hot? I’d imagine that reflecting more of the suns energy would help them stay cooler.

I think the problem is that science today, in many fields, is slower and requires more work than it used to. With physics in particular there’s a perception that science should progress fast in spectacular breakthroughs. But the 1900s was a

I think hydrogen will definitely be a “feedstock of the future”. It’ll be critical for green production of many materials and fuels. But there’s no reason to use hydrogen if you can produce and use other green fuels with good efficiency. Hy

Solar will certainly use more land unless you build on rooftops or do agrovoltaics. But that’s not the norm for large scale production yet. Wind depends on how you calculate area used. The zone that excludes other wind turbines and resident

The artillery being sent to Ukraine isn’t very relevant for Taiwan. And much of what is sent to Ukraine is old stock that was about to expire anyway. If anything, this has given western countries an excuse to ramp up production of new moder

That discussion is probably even more out of date by now. I can’t imagine anyone would predict the scale of battery production happening today. That’s already starting to help with frequency regulation and short term balancing. Then there a

We also have a lot of things made of wood. They can last 100s of years if well taken care of. It’s inevitable that nature learns to break down plastic, just like it did with wood (there was a long period where trees didn’t biodegrade). I th

I know there’s a lot of hyperbole in this field. We often hear about these kinds of “revolutions”. But I honestly think this is quite revolutionary and that something like this design will eventually be the norm. It’s similar to how we use

Just because Airbus A380s exist doesn’t mean A320s don’t have a role. If you just need to get two people to a certain place in orbit, why would you launch a starship if a dreamchaser would do? Just need to strap it on a fully reusable boost

The issues talked about here are mostly about size (width, length), not weight. Yes, the higher weight of EVs is a bit of an issue. But not as much as people make it out to be. But there are a lot of big EVs now. I think it’s mainly due to
