Just by buying an electric vehicle I already have more than enough batteries to solve these problems for my household. The transition to EVs - which is a hard necessity to solve climate change, and well on the way - implies battery produc

I would say it’s clear that solar panels are absolutely working extremely well today, at least as long as you don’t live too close to the poles. Renewables all together is growing faster than nuclear ever did. And solar is now a huge part o

This is exactly what happens in Valerian and the City of a Thousand Planets.. the opening to that movie is fantastic. The rest, well I don't remember so it must have been forgettable https://www.youtube.com/watch?v=u0FX

Will definitely try this. YouTube Kids is just awful. It’s way too hard to manage what kids are watching, and somehow it’s very different if you give them a kids profile on your own account vs making a kids account with their own email. The

I think in some ways VW group has more experience with making/selling EVs than Tesla. They might not have the volumes of a single model, but they’ve been selling a much wider range of models than Tesla has for a fairly long time now. T

Frances energy costs are about as ideal as they could possibly get right now. They have significant maintenance and decommissioning costs ahead of them. Right now it feels like they’re basically building up a form of debt, where they’re jus

These claims get thrown around all the time yet I’ve seen more studies that point toward balancing renewable being possible than not, and all-in-all cheaper than our existing energy infrastructure even with today’s technology. Once the tran

Many industrial countries already have lots of gas power plants. If they don’t actually need to run that often and don’t need that much fuel, just run them on hydrogen or biogas instead. Near zero investments to be made. Just somewhat large

This is kind of scary considering Chinas huge variability in quality assurance. I’m sure they can build with great quality most of the time. But it only takes one bad project to set the whole world back another decade or two when it comes

EU has set fairly aggressive target for battery and solar recycling. The supply chain will be far easier and cleaner when most of the materials can be gotten from recycling. Kind of a bad deal for China in the long term if you think about i

If you take into account fusion then the energy density of water is insanely high. Doesn’t mean you need to worry about it. It’s a myth that energy density is a reason to worry about batteries or any other form of energy storage. How much e

Geothermal is not sexy. It's incredibly boring. I personally also think we should put a lot more effort into geothermal. Yet I've watched two orders of magnitude more videos on nuclear fission and fusions on YouTube. "Just dr

It’s interesting that advanced geothermal energy is mentioned first in that sentence. I honestly think geothermal is likely to be far more important than nuclear within a decade or so. If it can be shown that advanced geothermal can be done

Russia has energy independence and food security. China has neither. The kind of sanctions Russia has gotten would hurt China far more. You can’t effectively blockade Russia. A blockade against China would be devastating. No, they can’t get

From what I understand the whole point of the solution is that you don’t have to remove their equivalent of a drill string while drilling the whole. It can all be done in one continuous operation. That’s why it’s so much faster. I’m not sur

Yeah, and think about the amount of political support you could get for geothermal projects if workers from the oil and gas sector could see a clear and easy path to adapt their skills. Globally viable geothermal power generation would be a

If we’re going to go back to geoengineering the atmosphere there are probably much less harmful ways to do it. I believe there’s a solution where ships just spray sea water into the atmosphere.

"We should stop talking about it as transitional technology," Why? It’s inherently a transitional technology. It is a technology that will necessarily destroy itself. Especially in a market with a growing share of BEVs as well.
