You’re also potentially blocking a seat that could be used by a paying passenger, and the operator will statistically run more/longer trains at higher cost to cope with increased demand.
Germany is struggling to get people on-board with a green energy movement that involves banning high footprint domestic heating systems (e.g. gas boilers)-- thus forcing people to migrate to heat pumps. A low-income family who was interviewed said it would cost €45k to install a heat pump in their terraced home in Bremen....
The issue is that the original radiators were sized to move the necessary n kW into the room with a water temperature of 60C. If you drop the water temperature to say 45-50C, you’re only going to get roughly two-thirds of the heat transfer. The other third needs to be made up somewhere else - additional heating or better insulation.
Running continuously is usually the ideal point. For heat pumps, it definitely is as the efficiency is highest with the lowest split between indoor and outdoor temps.
The issue is that if you suddenly want more heat, you first have to raise the water loop temperature before that can start pushing more heat into the house.
Systems are usually designed to keep up at perhaps 22-24C even on the worst days of winter; maintaining 17C is a lower target that can be met with less capacity and cooler radiators.
Tiny house = very tiny and probably new and well insulated.
Estonia also likely has very low labour costs and less difficulty finding staff.
Hydronic systems are usually in the >15kW range, and often have split indoor and outdoor units so you need to both do the refrigerant piping between indoor and outdoor, and the water piping to the radiators. Many systems also include domestic hot water heating as part of the same system, so three separate sets of plumbing.
In most of the first world, purging linesets, vacuuming, and releasing refrigerant is usually ~$500.
I think some of the USB ports come directly from the CPU, others come from the chipset. This allows the dirt-cheap A300 boards to operate with no chipset at all but still have a couple of USB ports, and likewise with laptops.
I first thought it was a camera but there was no point, After some searching I found that these things could communicate optical, so that might be it, if so how do they work?
Hmm. They’re very common in NZ now, however it appears that document is talking about modulating the actual normal shop lighting, not just an independent transmitter.
I redid the electrical in a supermarket already fitted out with Pricer gear, and we went from dumb electronic-ballasted fluoros to dumb-driver LEDs, no DALI and certainly no comms uplink or modulation smart enough for that. I’m aware that the document suggests power-line communication to the drivers, but these were off the shelf dumb drivers/ballasts.
The ceiling mounted Pricer transceivers would have been doing all the transmitting, and as I never saw any visible light coming out of them, and the HF ripple and instability from the shop lighting would have been significant, I think it’s pretty safe to say they were using some form of IR.
I think I saw a video on this from Battleship New Jersey.
The main time that displacements and ship sizes were actually standardised and restricted was due to the various naval treaties from about 1900 to WW2.
Before and after that (and to some degree during), sizes of each class of ship gradually crept up and up as technology advanced and everyone wanted a frigate/destroyer/cruiser/battleship that was slightly better and thus slightly bigger than what their potential opponents had. Scope creep.
Prior to WW2, this simply meant that the biggest ships kept getting bigger and bigger, and then other classes were 1/2/3 sizes smaller.
Post-WW2, while each class kept getting bigger and more expensive, the advent of air as a serious threat meant that the largest ship class just disappeared - the US hung on to battleships for a while for specific applications, but never built new ones. Too expensive, too many eggs in one basket, and not enough actual need. No-one expects to have another big naval slugfest; radar, aircraft, and missiles have obsoleted large naval guns and armour.
Each successive ‘large gunboat’ class has disappeared somewhat later, as it reaches the point where politicians and admirals decide we can’t risk losing this many people and this much cash in one hit.
Aircraft carriers have stuck around because they’re very useful and they’re not intended to go within range of enemy heavy weapons, but a battleship with 16" guns and armour to suit is very overkill and expensive for anything but fighting another battleship. Shore bombardment is about the only role they could have left, and much smaller ships do that just fine.

Fibre optics can be used to measure a remarkable number of properties.
The electrical transmission industry makes significant use of fibreoptic current sensors, and distributed fibreoptic temperature sensors.
The latter is particularly useful as you can measure the temperature at any point along the fibre’s length, allowing you to detect hot-spots in cables.
Cicadas are pretty loud; I’m sure you can pick up much quieter things with a fibreoptic microphone.
Define ‘waste’. Depending on the plant design, a good chunk of the cooling is achieved by evaporating cooling water into the atmosphere. That could be waste.
Does the air blown through a wind turbine count as waste going into the atmosphere? Same for hydro going downriver?
I’m going to call this a stupid argument: we treat waste with the level of care the waste deserves, CO2 notwithstanding (and carbon capture being junk). Nuclear is expensive partly because its waste actually needs to be dealt with carefully.

The NZ gun laws are largely based on this idea, at least in terms of being a tool for use against animals, less so personal defense against other people.
The implication of this is that some types of gun have few/no practical use as a tool other than for personal defense/offense.
Rifles and shotguns are useful for hunting. Fully automatic & select fire weapons are not, or are at least excessive. They’re only useful if you intend to attack people.
I think you may be going down the SovCit rabbit hole yourself.
Yes, that’s basically accurate for contracts. Actual law does not require you to consent to it. An entity with the authority and ability to unilaterally create and enforce law is basically the definition of a government. By existing within their territory, you are subject to their jurisdiction.
Many countries do not have a formal constitution. The constitution is a limit on the powers of government, not the source of the powers in the first place.
The state is required to notify the public because the state has decided it is required to notify the public, and the constitution, formal or informal, sets out that requirement.
In parts of history and the world, there is/was no such requirement. The Sovereign’s word is law, with no need for statute to be published or breached.
A contract needs both parties to agree to it, and to any changes, not just be notified. Laws are unilateral.
“Congress shall make no law” is the most basic of restraints. Yes, there are other parts mandating how aspects of the government shall be operated. That’s because the US government was formed with a written constitution, more-or-less fully formed.
In governments that evolved over more centuries, like the UK (and I believe pre-CCP China), the initial assumption/assertion is that the sovereign has supreme executive power. Statute and case law may restrict this, and transfer power to the other branches of government that are formed - but theoretically, power flows from the grace of god, the mandate of heaven, or more practically the tip of a sword. The state has a monopoly on violence.
