The New Covent Garden Market itself is currently in the middle of a multi-decade redevelopment, they've slightly reduced the footprint and sold off some land for development, and t…

Instead of wood _or_ plastic, you have wood _and_ plastic in one board! (Or rather, paper mixed with some sort of formaldehyde resin)

The TV license is certainly bit ridiculous, but being legally blind doesn't necessarily mean you can't see at all, just you fall below the legal threshold where it's judged that po…

The whole concept is unfixable. Once the fibre comes out, it's not going to go back in. It's that deadly combination of fragile and cheap. Just unpack a new drone and off you go. D…

The drone moves, the base station doesn't. The spool goes on the thing that moves, so it just has to unspool to move further. If the spool was on the fixed position, the drone woul…

There are! https://www.omenie.com/pipistrelle.html

For datacentres that require air conditioning as opposed to natural ventilation (most of them) a very popular approach is to use evaporative cooling towers [1] in combination with …

There's a physical product that implements the same idea [1]. I'm not sure how it actually works (presumably there's a patent somewhere, is there an alternative solution?) but it's…

An interesting construction detail of the cheap modern microwave is that it only operates on one half of the mains electric waveform: microwaves use a single high-voltage diode whi…

I think GP means "enclosed".

dent, crush, lid or seal failure (which can't be cheaply/practically made of steel)

Somewhat of a meta question for @luu - how did you come across this post today before you resubmitted to HN? I ask as I ended up searching for this article earlier today and though…

For context, when power grid engineers talk about relays, they're not talking about physical switching of the electricity itself, but instead the control and monitoring system for …

At least for mains electricity, there is a good argument for using the derived W and the doubly-derived Wh (J / s derives W, W * s, derives Wh). It makes sense because electricity …

AN-8 is kerosene, similar to JP-8, but with a lower freezing point specification. https://erdc-library.erdc.dren.mil/jspui/bitstream/11681/243...

You can't. Starlink satellites are in LEO, not geostationary orbit.

This is definitely an interesting take on tunnelling, but I struggle a little bit to see how this would be either faster or cheaper than conventional methods. First off you have to…

Well, that issue explains a lot. The data source went missing, so the website just made up some data and used that instead! That whole website is a nonsense, what's the point in vi…

The visualisation on that site is good, but it's sadly plauged with data errors. The UK data doesn't seem to correspond to any other source I can find. I think it might be delayed …

Sadly, in my experience, the apple variety alone doesn't actually have that much bearing on quality (although a red delicious will always be lacking in the second of it's nominativ…
