I made a point of tracking Solid Energy Systems back when they were young and were just announcing their “break through” battery technology. What’s interesting was that they seemed to go off the radar when they got their investments and ini

As someone who didn’t know anything about this power station I thought maybe it was built from the start as a biomass power station. But it seems that it’s a huge coal power plant that has been converted to biomass? This seems to me like th

Yeah, successful advanced geothermal would be a game changer for combatting climate change. If we can transfer even a fraction of the workers, engineers, technologies and capital from the oil and gas sector it will give an enormous boost to

As far as I’ve understood the EV sale slump is mostly explained by a reduction in sales of cars in general. I wish the article mentioned that. It’s interesting that the slump happened at a similar market share point where the EV sale had a

Spinach is also mildly detrimental to health. (Oxylates) Doesn’t mean you should think that it’s bad for you unless you have a problem with kidney stones. Both black coffee and tea have several well documented health benefits. Even caffeine

Doesn’t surprise me. Visiting California right now, it feels like Norway around 2015. You see a few fast chargers here and there all over the place. But far from the amount of gas station pumps of course. The transition in Norway from 2015

Battery prices are only a problem for the short term. We’re already starting to see batteries becoming so cheap that people buy batteries with 100s of Wh or even kWhs just for camping or other occasional uses. We’re starting to enter a worl

I love nuclear technology, but I feel like most nuclear proponents are pretending that the last 5 years haven’t happened. It’s now basically inevitable that anywhere with an OK amount of sun throughout the year will build enough renewables

I’d like to add that there’s a negative externality with nuclear power that’s rarely talked about: they’re thermal power plants. They heat up the local environment which can sometimes be a problem depending on the setting. But more importan

Baseload power is becoming an outdated concept. We have all the technologies to shift power to when it’s needed at a reasonable cost. Several regions is already shifting a huge amount of power by hours, and the capacity has been added in a

I also think we should work on geoengineering, but I also agree with those that fear that it will make us complacent and facilitate continued emissions. So I think the time we start geoengineering needs to be after we’ve seen some really hu

The difference in volumetric energy density is not that big though, and hydrogen is not as flexible as jet fuel or even batteries when it comes to how you can store it in the vehicle. To be fair, high gravimetric density is a fairly large a

I don’t want to buy a device that can run any code, even if it’s apparently (hacking or force can be a factor) by my own choice. Especially for a device that I also use for contactless payment. I want full confidence that I can buy a second

If we learn to live forever before we learn to die willingly, humanity will become a cancer. We have not even legalised assisted suicide in cases where it’s clearly needed so we are really far from having a culture of dying gracefully. By c

I think 2050 is a reasonable goal to get to 100% renewable/clean (including nuclear to some degree) for all energy. Then we need to average, what, around 4TW/year for two decades? Considering how fast solar/wind is growing, t

For Northern Europe there’s also hydro power. Norway is basically all hydro power plants and is well connected to its neighbours. And there’s trash burning power (with district heating). Norway, Sweden and Denmark has a few of those. Possib

Why do EVs need a lot of it? Our Kia Soul EV 2015 model doesn’t have any more software than its gasoline counterpart, maybe a couple extra menus related to showing EV info, that’s all. I doubt that the software for the inverter is any more
