If you’ve installed the appropriate filters in your premises (to ensure that the fridge and freezer only receive cold electricity, and to make sure that the TV gets a full RGB supply, etc), you should be fine, as these also typically filter out impurities into a small tray - make sure you empty these trays on a regular basis - with the power turned off, of course, or else impurities continuing to be filtered may leak onto the carpet.
Thanks, Mangetout, for your expertise. On a related note, when the switch to a light fixture with an empty socket is left on, how long do I need to leave the doors and windows open in that room before the electricity in the air is dispersed to safe levels?
Also; be vary careful when handling vacuum. It has no smell, and it can kill you in a couple of minutes. It’s also infinitely compressible so a small bottle can contain an unlimited amount of the stuff. This is why you should always make sure to correctly re-seal your vacuum bottles after use.
Joking aside, there really is such a thing as “dirty power”, also known as “AC hum”, a side effect of sharing wiring in your house with things with generators like A/Cs and refrigerators. It can cause periodic spikes and dips in the voltage, resulting in distortion or interference in video display devices and amplified audio devices.
It sounded like hokum to me until I had this problem with horizontal interference lines moving slowly from the bottom to the top of the image coming from a video projector. I gave one of those “Monster” power bars with a “Clean Power” system a try, and it went away. Either plugging it directly into the wall, or using a standard surge protector strip resulted in the problem coming back. Huh.
One thing that worries me is related to cars (or other vehicles).
Lets say that you are driving at 50km/h, and come up to a red light, so you stop, right? Now where does all that speed that your car had before the stop GO? Am I supposed to believe that it just DISAPPEARS? No, I believe that the governments aren’t telling us the truth about this, and I believe we will soon have big problems with speeds polluting our streets, and I don’t think I have to tell anyone how dangerous THAT might be.
There’s actually a theory that some impurities are good for the immune systems of electrical appliances. If the electricity is too pure, then they become prone to all sorts of allergic reactions. You * do not * want a refrigerator with a peanut allergy or a vacuum cleaner that’s allergic to dust mites. (Interesting factoid – a vacuum cleaner can sneeze at nearly 300 miles per hour.)
I would also suggest that you consider the Campbell theroy of fluid electricity which states: If you don’t have an appliance pluged into a wall socket, the electrons will flow out of the wall socket and all over the floor creating a mess. You should always have all your wall sockets with plugs inserted into them to prevent this electron mess.
