what happens to a coffeemaker if it has been left on for 42 hours?

If it had boiled dry it was way to hot and you don't know what that did to the internal components. With the fire risk that could impose, I would either have it looked at by a certified repair center for that brand or buy a new one. If there was still liquid in the pot, the risk would be greatly decreased. My husband is the world’s most forgetful person so eventually we had to get one that automatically shuts off an hour after it brews. Lots of them have this feature.

Very dark room.  Quiet area of the house.  Try using a noise maker like a fan or something that you will get used to and can drown out the sound of the lawnmower.  Don't drink coffee 4-6 hours before you crash.

It will make it worse... Stay away from coffee, I don't think you should buy it anymore, you will get more addicted, don't do it!

Yes it is possible. Coffee breaks don't have to be so technical.

Boiling the water for 5 minutes will kill bacteria and such, but the suspended particles will remain in the pot. You would have to collect the steam, and cool it down to condense it back in pure water, only containing H2O.

Yeah, Im pretty sure wrapping your hands around it wont affect it at all. And only a paper cup would be affected at all obviously.\n\nYour hands are generally room temperature, and even if they warmed up from holding the coffee, they would only be effecting a small amount of surface area of the coffee -ie the coffee on the side of the cup.

Well, the omen or portent is you're going to have to clean the floor, and make another pot.  Depends on how you look at it, in all honesty.  Yeah, it sucks that the whole pot got lost; but maybe that pot had a gnat in it.  You didn't get hurt, you probably have more coffee, and it didn't get spilled on the way to work all over your new white shirt.  Perspective is everything.

As others have said, much more electricity is used if you leave it on all day.  However, if you're going to be using it at various times during the day, by all means leave it on - saves time and wear and tear on its parts.

the conclusion is that when you heat water it will boil.\nif you donot stop it will ecoporate

Most appliances use no electricity when they are off. The exception being TVs and computers, they use a small amount of power to stay warm for quick start up. If you want to see for yourself, go outside and look at your electric meter. You will see something moving, usually a dial. Then turn all the breakers off at your circuit breakers panel. The dial will stop, meaning you are using no power. Then unplug everything on your kitchen circuit except your kettle. Turn it on and off and check the meter, if the dial is moving, you're using power. If it's not moving, you're not. For sure. You can check everything in your house with this method.

The power supply might have gone out.

it depends on the load and the nature of the large appliance\nthe flush example was great but it does not describe dthe momenteraly effect ( it was nice though).\n\nwhen you deal with inductive loads there is something that is called start up current.  it can be 2 to 6 times the nominal current under normal operation. that means that if a device needs 2 amperes of current when it is originally powered the consumption may reach till 10A. then the current returns to normal copnditions. \nall due to inductive and self inductive effects where the device opposes to the change and so on till an equilibrium is reached.\n\nthe demand of the current during start up is great and that is way momentarely  the lghts dim.

How long? That depends on the pressue, how warm/cold the water already is, and what you're trying to boil it with.

The previous poster stated that it will not work, but that is not exactly true.  He is correct in that a pot with a water and a small hole in the bottom will leak water at different rates throughout the day (a lot in the beginning, less later on) because of the pressure of the water column.  The egyptions overcame this obstacle.  What you need to do is have another larger pot that spills into the pot with the hole so that it is always maximally full.  It can spill over into whatever you have to hold it.  The key piece is too have a pot that you will make notches in to keep the hour as it collects the water from the pot with the hole that is kept maximally full.  Since the water is coming out at a constant rate all you have to do is start this off and after each hour make a mark on the inside of the collecting pot.  It you can do this for twenty four hours, you have a water clock!
