I'm not a fan of SRM, but this isn't true. The idea people in the SRM research community have go more like that you have declining CO2 emissions, at some point you turn around by deploying negative emissions tech and SRM is basica

What I find noteworthy and maybe isn't appreciated enough is how many of these large solar installations are in countries like India or China. You may implicitly think that these would be in the richest countries, but apparently they a

> what? who claims this? A very pervasive argument against renewables is "but storage!!!". That's one form of this type of argument. There isn't much storage needed for renewables unless you get to very large numbers.

I think the "processed food" guidance is widely misunderstood. From what I gather you shouldn't consider that as a strict rule. It's more a rule of tendencies. Less processed food tends to have more fiber, less sugar, le

I'll give you one example which I find pretty convincing: Take aviation. You can make aviation green by using hydrogen (on medium distances), batteries (on short distances) or efuels (everywhere, it's basically kerosene, but made

Huh, is that so? Why? Anyway, I haven't even said whether I agree with him or not (which tbh wouldn't be very relevant, as I know where my limits are, and judging debates in physics is definitely outside my area of expertise).

There are a bunch of people with similar thoughts. Just recently a blogpost by Peter Woidt showed up here [1]. While I'm only following this as a lay person I think you can say Woidt and Hossenfelder come from the same corner of "

"It's complicated". CBC does not provide authentication, thus it does not protect your encrypted content from manipulation (which can enable all kinds of followup attacks). Generally you should avoid using unauthenticated cip

Key point to avoid any confusion: This is about the RSA-SHA1 cipher combination. It does not mean that RSA is deprecated. If you use an RSA key for SSH (server or client) you can continue using that. This should not affect any modern-day

You're technically right that wind is an indirect form of solar energy. You're not right that this would imply that solar is any "better". The wind will blow whether you use its energy or not. You're not "more

That's an exceptionally inefficient way to do it, and it comes with the risk of methane leaks (which would then have a climate warming effect). Hydrogen can be used directly, which skips one conversion step and doesn't need air ca

The problem with trials registries is that they're only one piece of the solution, but many more things need to work for them to be effective. Many trials are registered, required by law to be published, but still not published, becaus

AFAIR there isn't much to "extract", you simply use any application that can decode the QR code and you get the key which is encoded as a sequence of letters and numbers.

I'm not entirely sure why this comment gets downvoted, because it's spot on. QC is impractical for any real-world network, and the idea that it could ever play a role in the real-world Internet is just fantasy. But also we don&#x2

There is nothing unusual about any of this. A drug should be approved once it is very likely causing more good than harm. But obviously that doesn't mean you should stop researching that drug. What's happening here makes perfect s

Ammonia has potential safety issues, but you should be aware that there are already ammonia ports and ammonia ships. Not using it as a fuel, but transporting it. So while ammonia needs to be handled safely if it's being used as a fuel,

Which is very energy intensive, as you need to capture CO2 for this to work. And it adds the problem of methane leakages (methane itself is a powerful greenhouse gas). The most promising chemical to use as a hydrogen carrier is ammonia. It

The biggest misconception about hydrogen is that it has something to do with cars. The whole "but BEV!" discussion is a distraction that has nothing to do with the real use cases of hydrogen. Hydrogen will be extremely important i

I can recommend a great article answering that, however unfortunately it's in German [1]. But the gist is that there are two major unsolved challenges. One is finding a material stable enough to let the reactor run for longer times (al

Take a pill every day vs. get a vaccine every few years? I don't think the vaccine will have a marketing problem.

So you're saying the people who were shouting at people standing in line to get a vaccine against covid (which happened plenty of times in Germany and I'm sure in other places, too) are not antivaxxers?

by hannob 5y ago
From what I understand the vaccine wasn't taken off the market by the FDA or science. It was taken off the market by the company producing it, due to pressure from lawsuits and bullshit concerns about risks.
