Locomotives than run on diesel have diesel-electric transmissions - basically the diesel engine acts as a generator, with electricity that turns electric motors. When the UK electrified a lot of its railways in the 1970s, some diesel locomo

The problem isn't technical feasibility but regulation. My city is one of the coldest (by lows, not average) capitals in Europe, and we have some of the strictest regulations in terms of energy requirements. New buildings have to be bu

A big plus of being a landlord in our current time period is that what you charge the tenants in rent covers: a) the cost of your time b) the cost of maintaining the property c) the cost of paying interest on the loan d) the cost of repayin

I live in a post-Soviet country that has district heating systems, and rather quickly the demand for heat outstripped the demand for electricity, so in my city this is now mostly fulfilled by 'heat plants' burning gas. The price y

I wonder if that is considered a copyright violation. The customer is giving you X and you are giving back Y. But Y is not copyright. It could be considered a derivative work, but what if you change Y, so it's a couple of degrees off o

In my part of Europe the price of half a litre of petrol is around the same as a kWh of electricity at home. If you use public chargers (there are no Tesla Superchargers here), then yes, it will be more expensive than the equivalent ICE car

Most laptops have the fan speeds set overly aggressive. I bought a Asus Zephyrus last year and by default the fan was coming on and off every few seconds, I tweaked the fan profile and boost policy so now it rarely comes on at all for regul

In vanlife some people have built recirculating showers that use just a few gallons of water running in a loop. They run it through particle and UV filters which supposedly clean the bad stuff out, but I haven't seen any scientific stu

The problem isn't so much what work looks like, but how to measure it. I'm kind of surprised with the shift to work from home (and in some cases back again) we haven't seen any large companies come out with analytical data ab

You would hate my country's language then. Diminutives are used in everyday conversation by adults, for no reason other than it sounds more fun.

I would not suggest trying to change your job or start a business when you first become a father. The first few months or so it's easy to leave everything to the mother, as the baby is basically just feeding and sleeping and pooping. I

This is really no different than what other countries do, e.g. US border officials extensively questioning foreigners or asking for usernames and passwords for social media. As a visitor you have to abide by the law of the country, which ma

My company recently gave up on acquiring another company, mainly because their backend is written in PHP. Not that there is anything wrong with PHP, but we deemed it too expensive to expand the team, because there are a few big companies th

Another approach would be to have a longer length of piping. The rate at which the soil temperature drops when you extract heat, and then 'recharges' naturally, will vary greatly if you have 100m vs 1000m of piping. This is why gr

I think I have similar feelings. While studying and in my early 20s I spent a lot of time trying to build a side business (a la Four Hour Work Week) so I could have freedom to spend my life how I wanted instead of working all the time. My p

One of the big problems in the UK is that housing is not built like that. In most of the UK it rarely gets below freezing, yet even new homes come with big gas boilers because of how poorly insulated they are, and if you turn it off for hal

Bear in mind that if you plan to recharge from the grid when the power is on, that's just going to exacerbate the problem of gas shortages. In California or Texas you could recharge with solar, but in Europe, solar during winter is bas

If Europe has rolling blackouts this winter, the purpose is to reduce energy, and hence gas, consumption. If everyone were to charge a battery bank when the power is on, to see them through the time when it is off, the net result would be i

Oh I forgot they added wireless charging in V2. Yeah that part of my argument doesn't really make sense then.

Why? I got a new shaver recently and it has a 5V 1A charger. The old one had a 5V 0.5A charger. A common interface would make perfect sense, and the power range is within what the USB standard can provide.

Are you old enough to remember the early 2000s when every phone and portable media player had it's own charger, which often wasn't even transferable between devices by the same manufacturer? It led to lots of old chargers when dev
