Now I realize that what I really want to build is a kettle with two 3kW heating elements. On a UK ring main, I can plug the two elements into two neighbouring sockets and still have headroom before I blow the breaker. I can cut my time-to

According to Twinings tea: Always use freshly drawn (filtered if possible) cold water in the kettle. Tea loves oxygen as it helps the flavour develop. Most of us are guilty of the following... looking at the kettle seeing there is some o

Ours is a Smeg model. The two large rings are 2.3kW, with a outer booster ring to 3kW. The problem is if I'm just boiling water for my tea with a saucepan, only the inner ring is triggered. I can put a large pan on there and get 3kW

We have an induction stove too and it's great. But the kettle is still significantly faster at boiling water.

As a Brit, the best thing about 230v is being able to run a 3kW kettle to make my tea. I took this for granted until I moved to the US.

I have this watch and I love it. It's incredibly light due to titanium case and strap, and very tough with sapphire glass. Solar powered, so never needs the battery changing, and always accurate due to the radio receiver. And I like

Generally to turn left you bank left using ailerons. This angles the lift vector to the left and the airplane will turn that way without using the rudder, but it's not fully coordinated - the plane won't be pointing properly into

I guess you're talking about as a country. But as an individual in the UK, I'm better to wait. Switching now doesn't help CO2 emissions and sometimes hurts, prices will likely be lower in future as production scales up, I c

Yes, but there's little point in electrifying heating until you have a cleaner grid. Right now, the marginal source of power in Germany is coal and in the UK is mostly gas (occasionally coal). If you switch your heating to electric h

Right now, Germany appears to be 85% renewable [0], but is still pretty mediocre on CO2 emissions compared to many of its neighbours (Poland excepted!). That 8GW of coal still hurts, but the trend is pretty good. [0] https://app

At least in principle, for a patent to be valid it must be enabling. If other words, someone "of ordinary skill in the field" should be able to read the patent and implement it. If there's not enough information in the paten

I answered the same way as you. Because there are rules and there are laws. The only reason park rules have any weight is in a larger context of laws. So, if the only park rule is "no vehicles in the park", then clearly the rul

Good question - I guess at least I showed I could figure about for myself how GIF images work, and showed some initiative. I never asked the Professor if he actually had any other qualified applicants for the job - maybe I was the only one

Back in 1990 I was several years into a PhD in neural networks, having fun, but not really making especially useful progress. I spent a lot of time trying to get some simulated bugs to learn to move around, find food, and generally learn h

Riding a motorcycle obviously derives from riding a bicycle, and that presumably comes from the earliest bicycles where you pushed the ground with your feet. Riding definitely seems a better term for that than driving. I guess you can say

Sequence diagrams are very useful, but UML just adopted a representation that already existed decades before. For example, the original 1981 TCP specification in RFC 793 [0] has ASCII sequence diagrams (see figures 7 to 14, etc). I don&#x

I'm sure someone can find an objection. For example, Belfast (UK) is "GB BEL", but isn't actually in Great Britain (it is in "the United Kingdom of Great Britain and Northern Ireland").

The main issue as I understand it is that you lose a lot of energy to heat if you just pump air straight in. To be efficient you need to chill the compressed air down to water temperature and store the heat before you pump the air underwat
