  1. What I do with tablets is that I break a corner off an throw that in the tub. Is that a good idea?

  2.  @larsalfredhenrikstahlin8012  "You should be able to plug un-grounded things into grounded outlets." Monkeh wasn't complaining about being able to plug ungrounded things into grounded outlets but rather about being able to plug grounded things into ungrounded outlets.

  3.  @Monkeh616  "CEE 7/2 ungrounded plugs cannot be inserted into 7/3 or 7/5 grounded outlets." But that problem probably isn't widespread. I think CEE 7/2 is quite rare and unearthed devices are more likely to use CEE 7/17 or Europlug which do fit into those outlets. However, it might be a safety issue if e.g. CEE 7/4 plug fits into some unearthed socket like CEE 7/1. Thought this was what you were complaining about in your first comment in this thread and if so I agree.

  4.  @vurpo7080  "Schuko, the one used in most of Europe, has basically all the benefits of the UK plug" Schuko lacks the fuse in the plug which the UK plug has.

  5. Note that at best you could use this argument for incandescent bulbs if your heating is electric. If your house uses district heating (which is mostly used here) or is heated e.g. with oil, that's going to be more efficient than electric heating when factoring in the losses in the electricity generation.

  6. You can think of the "+" and "-" applying to one specific part of the cycle.

  7. Is that legal?

  8. To nitpick a bit, I think this is an issue of knowledge (or sometimes laziness), not skill. These tips aren't hard to do at all. People who don't do them most likely just don't know about them (or can't be bothered if they do).

  9. That sounds a bit odd to me. If the heat ruins the taste of the coffee over time it shouldn't matter if it's heat coming from a hot plate or heat retained from the brewing.

  10.  @awandererfromys1680  I wonder whats the reason for the difference.

  11.  @whuzzzup  Now that I think of it, that sounds a bit weird. Does that actually happen or is it just movies. Where I live (Helsinki, Finland) also has district heating but I don't recall ever seeing such "steam", not IRL nor in movies or TV series.

  15. 9:48 But does that work for double-sideband or single-sideband signals?

  16. Did you buy 50 Shades of Gray to make that joke or had you bought it earlier to actually read it?

  17.  @johngamble5270  It seems like the most viable fallback option if rewiring doesn't get approved.

  18.  @mariusvanc  It's at least fairer than not paying or not being able to charge an EV at all. Of course, installing proper equipment is better.

  19.  @thegreatoutagesign9204  "its not the gasses that conduct the electricity. Its the fire" The fire is just hot gas. "its a plasma" No, it's not.

  20.  @thegreatoutagesign9204  Plasma by definition means: "a state of matter in which an ionized gaseous substance becomes highly electrically conductive to the point that long-range electric and magnetic fields dominate the behavior of the matter". A sufficient amount of ionization for that requires temperatures in excess of 10,000 K. The fire in your heating furnace is nowhere near hot enough for that.
    1
  21.  @thegreatoutagesign9204  10,000K was a figure I found googling for a lower limit for (thermal) plasma temperature. "Natural gas burns at 3,043K" Where are you getting that number? Wikipedia lists it as burning at 1950 °C (2220 K). https://en.wikipedia.org/wiki/Gas_burner
    1
  22.  @Owen_loves_Butters  It's not according a typical definition because the degree of ionization in a typical flame is rather low. Of course, that depends on where exactly you draw the boundary between plasma and gas which is somewhat arbitrary. However, fire isn't usually considered plasma.

  23. Next: An actual personal AC. The way it should work is through an actual closed cycle. Then it can blow the cool air into your face and the hot air in the opposite direction. Might not be a paragon of efficiency but it should at least give you an illusion of working when you switch it on. Btw, if one already has a fan, I wonder if just hanging a wet towel in front of it would work as well as the devices in this video. (I saw this trick mentioned in a great anime called Battle Programmer Shirase.)

  24.  @randomeverything3023 : "Inside, however would increase the rooms temp by adding the heat from the compressor." But I think that alone wouldn't stop a device like that being peddled. The rise in room temperature comes with a delay whereas the cool breeze to one's face would be immediate. People might not realize how inefficient that would be.

  25. It hadn't occurred to me that someone might want to synchronize turn signals this much.

  26. Detergent pack manufacturers should start to make 2-piece packs that can be broken into 2 so you can put the smaller one into the pre-wash compartment. That should be fancy enough to catch the consumers' attention.

  27. Would it be possible to use water at the condenser end to increase efficiency?

  29. I think it's powered by gas, not gasoline. OK, "gas" can also be short for "gasoline" but I think in this case it's actually gas. (Or maybe you were being sarcastic and I failed to detect it?)

  30. Does RCD/GFCI work differently with split-phase 240V and "normal" 240V (i.e. with hot and neutral wire)?

  31. Could an actual etymologist confirm which theory is correct?

  32. 0:04 "If you live in an area that gets pretty cold during the winter time, odds are you have a gas-fired furnace heating your home." Nope. My home is heated by district heating with the majority of that heat coming from CHP plants. It seems such an obvious solution in cold climates (at least in urban areas) that I'm surprised it's not being utilized in all areas fitting that description.

  33.  @geekygirl2596 : "What is "district heat?"" It's a type of infrastructure where heat is produced centrally in some kind of plant and transferred to homes through pipes with near boiling water flowing in them. Here most of the district heat is produced in CHP plants, i.e. plants that generate both heat and electricity which is pretty efficient. Apparently, for some reason, district heating isn't very common in the USA? Though some comments here seemed to say that it's used at least in New York City.

  34.  @AsterInDis  Mirrors can't function asymmetrically.

  35.  @AsterInDis  "I know we can't get turn-on-turn-off windows" Boeing 787 Dreamliner has electronically dimmable windows. "window films exist that make it so that heat is reflected off what kinda looks like a mirror but allows a sufficient amount of light in" Windows that reflect infrared but not visible light were talked about in this video. They're obviously possible and that's not what I was reacting to. The part I quoted wanted windows that reflect IR only on one side which is impossible because reflection on one side but not the other would violate very basic laws of physics. In short, one-way mirrors cannot exist. The "one-way mirrors" used in e.g. recognizing a perpetrator of a crime are just half-reflective mirrors and the "one-way" aspect is simply one side being lit much more brightly than the other.

  36.  @Owen_loves_Butters  It's definitely not possible. It would violate some very basic laws of physics. Bulletproof glass is a different thing because the process where either the bullet or the window breaks upon collision is not a reversible process.
    1
  37.  @Owen_loves_Butters  I'm quite confident that it is impossible. Physics is (mostly) time-symmetric and a one-way mirror would break that. I think there isn't a reasonable argument that that could be overcome. Technically some particle physics phenomena exhibit T-symmetry breaking but those are not relevant to light being reflected off windows. Negative temperatures are possible in systems where the energy level is bounded from above such as a spin system.

  38. That doesn't make sense. Firstly, the cable has a wire going in both directions so there's no net inductance. Secondly, even if there were it would increase heating.

  39. You should have said the power ratings in horsepowers instead of kW. :)

  40. I guess the point was to get the effect without having to remember to set the temperature back to normal later.

  44.  @Thedamped : Which one of my comments are you referring to?

  45.  @Thedamped : If you're referring to what I think it was just nitpicking. If I remember correctly, there was a comment (though I don't see it anymore) of having over 100% efficiency due to the benefit you described. What I just nitpicked about is that you can't really describe that added benefit as a percentage of the energy consumed which is why the over 100% is technically not really correct.

  47. One advantage the US has in this regard is that American grid operators don't have to worry about TV pickup.

  48.  @travelinghermit  I don't think most of the heat from radiators is conducted to the air, not radiated, because they're not hot enough for significant radiation. They're even shaped to maximize conduction.
    1
  49.  @hairyairey  "air is a poor conductor of heat that's why" But a radiator also has to conduct the heat to the air. (Also, in the ducts the heat in the air moves by convection, not conduction.)
