This is also one of the positive side effect of electricity generation from ocean thermal energy. I've wondered for a long time why we're not investing more in this, as it's one of the few possible large scale generation mec

The unidentified "wrenches" [1] look awfully like a Trangia pan handle [2]. Wonder if they were used to hold a hot cooking pot? [1] https://miro.medium.com/max/4344/1*yF6s3HG4AY4WAQruLPSmag.jp... [2] h

If you look at the top computer systems and networking conferences, you'll see an increasing fraction of the research is from the top Chinese universities. The best Chinese students used to go abroad for their PhD studies. In the las

Those benefits would also be true in something like a Messerschmitt car: https://en.wikipedia.org/wiki/Messerschmitt_KR200 If we can build electric versions of this that don't need huge crumple zones because they

Pollen could definitely be a key part of it, but I doubt it's the whole story. Checking the PM 2.5 count for yesterday for the Bloomsbury sensor in central London, it's actually about 70% of that at any of the sensors in the East

Frying food seemed to be particularly bad, even with the extractor running. If it's not too cold, I open the kitchen door now when I'm frying. Burning the toast doesn't help either. And candles resulted in fairly high leve

My simple policy is I never give out any information if I'm cold-called. If they claim they're my bank, I say I'll call them back on the number printed on the card, and ask the caller which department I should be put through

I think the irony is that South Park is self-censoring for the European market. I know that's not equivalent to state censorship, but it's still ironic.

If a topic is voted up, then pretty much by definition, people here find it interesting. I did. Anyone interesting in how our nascent efforts to combact climate change are progressing around the world should be interested in how quickly e

Shame that article totally fails to measure what is actually important. It's not about energy efficiency, but about CO2 emmisions per passenger mile. In Europe, most trains are electric already. Around 50% of electricity in Europe i

In Europe, it's just starting to be regarded as anti-social to fly. Enough so that it's noticable in increased train travel and decreased air travel: https://www.independent.co.uk/travel/news-and-advice/

Almost all of their aircraft are leased, not actually owned by them. In the short term, they'll probably be impounded by the airports they're currently at, pending payment of landing fees. https://www.planespotters.net

Don't hotels realise this is a reputation business? In the age of the Internet, no-one with access to TripAdvisor or Google will ever stay there again. Wouldn't be at all surprised to see the hotel change name in the next year,

Looking at the last week's production, there's a fair way to go before gas is only being used at times of scarcity: https://electricityproduction.uk/from/all-sources/?t=7d Notice how the gas usage cycles

From the Google maps satellite images, it looks like there's a range of technologies that have been chosen for the panels and trackers too. That also presumably reduces risk of a large single failure mode as the panels/trackers&#

I wonder at what point most gas (petrol) stations start to be become uneconomical to run? As they start to close down, maybe range anxiety will start to become an issue for ICE vehicles. Is Norway getting close to this threshold already?

I would think that the most likely failure mode would be bird ingestion. A large bird would likely break the top prop, and the fragments of that prop+bird would hit the cowel, and then be sucked down through the bottom prop. Not to mentio

The real question, as I found yesterday, is can you switch on high-speed wipers, rear fog lights, hazard lights, and max-demist, in a few seconds, while you're devoting 99% of your brainpower to not crashing into an unseen vehicle slow
