There's diesel trains running out of Kings Cross, Euston, Marylebone and Waterloo as well. They're definitely the minority of train services overall, but there's still a lot of them.

The article gave the age of the oldest one (apart from the older guy) as 25, and apparently they've lived like that for 9 years. That suggests they were all children when they went underground. There's almost certainly some sort o

When a child is born it's generally common to register the birth. In many countries it's a legal requirement - which as a first step towards child protection probably isn't a bad thing.

Absolute numbers are a distraction. Retraining 1 person in a population of 10 has the same net demands as retraining 100,000 in a population of 1,000,000. Human society is massively parallel by default.

The jet fuel part of this is a distraction from the important (and hard) part - turning electricity into usable liquid fuel. Electrolysis is easy enough, and there's plenty of places with enough water. Then you have hydrogen. Hydrogen

Off topic, but there are a few cars with inboard brakes. The Hummer H1 is one.

If it had a button on the lid, it would just be another FM radio - not really a market that a small hardware company want to be in. The statement this radio makes by being untunable is literally the only reason anyone buys it.

Sleeping on a Vietnamese sleeping bus is definitely the most terrifying nights sleep of my life. You wake up at 2am, look out the front window and see a truck powering straight at you, before one of the drivers swerves at the last minute. S

I wonder what the life of the aircraft needs to be before the higher cost of the aircraft amortises into lower overall costs. I'd imagine that the running cost of a mainly solid state aircraft is significantly lower than a gasoline one

But then you've basically got a machine which turns iron into iron oxide and hydrogen, which you'll then have to put loads of energy back into to return to raw iron again. At best its an energy storage method. I can't imagine

The power generation potential given is in units which make it almost useless. A kWh is a unit of energy, converted into a frame of reference more useful than the joule. Saying that a device can generate 2 kWh doesn't really tell you m

There's plenty of affordable areas in zone 2 and 3 which have average rents considerably less than SV (a 1 bed flat might be £1100-£1400/month). Annual travel within zone 3 is £1648. It's really not comparable, especially sin

This is cool! I wonder if you connected just one of the audio outputs to a speaker with a crossover, the system would adjust to put the whole frequency range through it? It may also be that there's somewhere on the pcb you can tap into

The Pan Am building in NYC used to have a helipad, but there was a crash [1] and it was removed. Today most western cities have helipads tucked out the way - on the river in London and NYC for instance - for safety. Every time a helicopter

That's my question. Could you not just put a box over the plant for 5 minutes? Even if it needed to be a more elaborate system to simulate the correct rate of light falling and rising, it would surely be easier than waiting for an ecli

I think software development is a wide range of things, all the way from hacking on WordPress plugins to safety critical software. "engineering" comes in somewhere on that spectrum. Some software development is engineering, but no

I've got an aerospace engineering degree and have worked across a number of industries, from satellites to robotics. These days my job is about 50% software. Software development feels the same as other engineering design. You genera

That's a smart solution, but it doesn't solve the whole problem. Since I became aware of lamppost charging I've been counting the lamppost to car ratio. It's generally somewhere around 7-10:1. Even if you convert every l

Looking around urban streets in the UK, the biggest blocker to widespread electric car adoption is almost certainly charging infrastructure. Most people in cities here live in flats, terraced houses or other houses without driveways. Chargi

The tax free thing only works while they're a small percentage of cars. It might help drive early adoption, but at some point quite soon you have to start taxing otherwise income significantly falls.

The sun is more blue spectrum than any LED. The only way the northern hemisphere would have problems with too much blue light (compared to the equator) is if it was in midsummer, when there's a lot of daylight. Whatever blue light our

I don't think it does. Other sources I've read suggest the larger nacelle introduces a pitch up during certain flap configurations and at a high angle of attack. It's not the engine thrust that's the problem, but the dra

The startup I work at (Automata) is selling a robot arm for £5k ($6.5k). Getting the price that low took a lot of work and there's definitely mechanical tradeoffs to get there. Robot arms are pretty complicated electromechanical device

I'm sure it's doable, just be aware that it will take a lot longer and cost a lot more money than you expect. When your hardware project is "done" - that is, it works as you'd like, maybe you've made a handful
