I think this is the one covid fact far too many people haven't internalized yet. This changes everything. It means in essence for everything we do to slow down covid from spreading, we need to add additional measures on top of that to

> Why not use the excess to create hydrogen and store it? This is a very popular idea, but it doesn't work out as well as it sounds. The reason is that electrolyseurs aren't free, the capital costs are high. Not saying this is

The startup Bill Gates has invested in is called Boston Metal, they use a technology called Molten Oxide Electrolysis: https://www.bostonmetal.com/ But I'm watching the space a bit and it seems all the relevant compani

There's a very simple argument to counter this thought. It's true mrna vaccines are new, but also the sars-cov2 virus is new. Your question shouldn't be if you're worried about mrna vaccines, your question should be if y

Not saying this is good, but one should be aware that the flu shot is a bit of a special situation. Unfortunately it's a really poor vaccine compared to other commonly given vaccines, but it's an exception. The calculations how mu

This is a very poor article. The very first sentence is already wrong: "It could lead to net zero emissions for air travel." No, it can't. Aviation has a variety of emission sources, which include not only CO2, but also other

Here's a skeptical take on vertical farming: https://globalecoguy.org/no-vertical-farms-wont-feed-the-wor... Johathan Foley is usually well informed on these topics.

People without a cryptographic background may not be aware that this is even worse than how it sounds. SHA-256 is a cryptographic hash function. It's a good cryptographic hash function. But it's not a password hash function. They

Why would that make any sense? (Synfuels are really, really inefficient, you basically only want them in places where you need the high energy density and can't avoid them, like aviation.)

I find it amazing (in a bad way) that whenever you talk about hydrogen someone comes up and wants to talk about cars. There's a number of use cases where clean hydrogen will be desperately needed. This starts with areas where hydrogen

I used to think like that, but have eventually given up. SVN is easier to learn and much more intuitive to use. But even if you're not a power user you get to its limits quickly. (E.g. svn afair does not support bisecting by itself, th

I feel this starts from a very wrong assumption. There is the idea floating around that in the future we'll just replace classical computers with quantum computers. But even if we skip the challenges of actually doing that, what would

The possibility that a vaccine that has not shown any serious sideeffects until now will disable 20% of people getting it is extremely low. And you make the typical mistake of forgetting to weight vaccine risks against the risks of not vacc

I read that Pfizer/Biontech is currently testing whether they can go with higher temperatures, but those tests aren't finished yet, because the first priority was to get the patient data, and there they did what they expected will

Noone has tested single-dose. In this case it may sound like too much nitpicking, but the general principle is that you don't roll out something you haven't tested in a trial. In general this is a good principle. I hope they'

Curevac just very recently started with phase 3 studies. This means it'll be months before you can expect results. They may still play a role, as obviously the world won't be vaccinated within the next months. But they're als

There's no objective, fair way to answer that question. This is something that can only be answered by a societal discussion and hopefully some democratic way of decision. I'm not sure this is what you're trying to do, but it

If I understand this correctly this doesn't change that much. It means you can now safely use localhost, but you could achieve the same before by using 127.0.0.1.

Solar radiation management could be deployed in the short term. Whether there are catastrophic side effects is pretty much an open question.

Any sensible geoengineering plan will be in addition to climate mitigation and emission reductions, not instead of it. FWIW I think geoengineering should be - carefully - explored and researched.

What you do in one country absolutely matters in another. Even the US has a significant portion of wind and solar these days. This didn't happen because Donald Trump (or anyone else responsible) made any ambitious climate decisions, it

I mean the thing is: This obvious edge case was there since the start of the european emission trading system - and it wasn't adressed for more than a decade. It's good that they're finally working on it. But it's also s

The EU is working on adressing this on some level, they want to introduce something they call a carbon border adjustment mechanism. Details are complex and will matter in how effective this is and there's also a lot of resistance, so t
