Ideally your kitchen waste would go into a facility that properly handles it and will use it for energy production, but in a properly controlled environment (and if that energy production is biogas by avoiding methane leakage as good as pos

You can probably do that, but don't delude yourself that you're doing anything for the environment. Methane itself is a very potent greenhouse gas. Everything you do with methane is only environmentally friendly if you have a very

There already is a lot of pumped storage. It's the most important energy storage technology today. The biggest problem with it is that you can't built it everywhere.

It is actually quite simple to convince industry: An industrial facility will do that if the incentives are aligned that it makes them more money. The interesting thing is: The really challenging part of electricity storage isn't that

I think the key problem is that people misunderstand what CVEs are. Ultimately CVEs are numbers given to a certain vulnerability. It helps so two people know they're talking about the same thing. A typical usecase would be that you hav

The reason this is not happening isn't a technical one. It's that people with a medical background will tell you this isn't a healthy utopia, it's a nightmare. Medical tests are complicated. They often have significant f

I remember someone saying that if the EU roaming regulation would've come before the Brexit referendum it might've turned out differently. In hindsight maybe that's a sign. The roaming regulation is one of the examples where

A lot of bioplastics turn out not to be so green if you run a full lifecycle analysis. Appart from that: Plastic has this somewhat unique property that nobody is really held responsible for its emissions, even in places where emissions are

Mix of a country well suited for hydropower (+geothermal) and political will. It's obviously easier for a country with lots of hydropower to go 100% renewable, as you have a potentially flexible source that not everyone has.

That's not how it works. Two 11 qbit quantum computers are not like one 22 bit quantum computer. Quantum computers become powerful when you can entangle many qbits. That's also the challenge, because building such a thing is hard.
671.
by hannob 5y ago
It's both. You can easily simulate 11 qbits.

I think this is a key misunderstanding. The issue is not that we don't know what useful things to do with a QC. The issue is the quantum computers that exist today are not able to do those things. "Adopting" a machine that ca

The field of quantum computing has made a bizarre turn over the past years. There exists a myth that qc is on its way to widespread use. This paper is a prime example. It starts with the sentence: "Quantum information processing is ste

This looks less ridiculous than the last metaanalysis on Ivermectin that was posted here. Still if you look at it there's some reason for caution. Not all of the included studies were RCTs, some were not blinded. If you look at the &qu

This thread is literally under a scientific publication investigating the effectiveness of Ivermecitin, but yeah, basically like Galileo Galilei. Except not at all.

The important sentence: "It won't generate power". It's all fine to do this as a research project. But this is not a technology that is going to solve our energy problems any time soon - and it certainly shouldn't d

You need huge trials to do this. The power of your trial comes from the "events", i.e. number of people who got symptoms of covid-19. Have 2 vaccinated groups? Not many events.

There were ideas thrown around to do one big study of various vaccines instead of multiple ones. Didn't happen, probably was too much of an organizational challenge and would've required all companies to comply to a protocol made

by hannob 5y ago
That is probably true, but do you have any proposal how such a trial should be done? RCTs are good when they can be done and I'm all for doing more of them and too often there's no good excuse for not doing them. But at some level

Ok I guess I underestimated the amount of effort people are willing to put into nostalgia while cooking...

by hannob 5y ago
It is hardly plausible that a gas grid will be kept operating just for cooking. Generating the gas probably would even be feasible, as the amounts are likely small enough that they could be met with biomethane generated from waste, but oper

Well, we will need to increase electricity generation while at the same time replacing existing fossil fuel generation. So that adds to the challenge. Not saying this is impossible, but it surely is a challenge.

by hannob 5y ago
It's been clear for many years that there are already more fossil fuel projects in the pipeline than what the planet can handle. This wasn't a secret. The fault of these companies was pretending that they can ignore the climate cr

So what? Wadham was also pretty wrong. "X was wrong, so I'll support the words of Y who was wrong in a different direction" is not a very smart position to have.

by hannob 5y ago
Wadhams is controversial, to say the least, and he's been wrong in the past. See e.g. here: https://www.opendemocracy.net/en/oureconomy/faulty-science-d... This is an issue I've been struggling with myse

It's easy to make that take. But try to see the story from the other side. The person writing that article is a journalist who almost certainly has no direct connection to the ad department of his site and the people who are responsibl
