A bar I visited the other day had old-school Edison bulbs hanging from the ceiling, and I noticed that in several of them, the filament was vibrating. And by vibrating I mean vibrating big time — swinging back and forth a full inch or so inside the bulb multiple times a second. The bartender didn't seem to know what caused it, but seemed to think it wasn't uncommon. Any idea? [more inside]
This is just a thought experiment at this point, and probably will remain so. In the back of my mind I have the idea that when my old SUV finally gives up the ghost I might rip out the internal combustion drivetrain and convert it to an electric vehicle, possibly with a removable range-extender generator. Setting practicality aside for the moment, can you help me envision what this would involve? [more inside]
I'm trying to figure out if it will be cost-effective to buy this electric toaster oven, versus using a large gas oven. [more inside]

Does my window air conditioner use just as much electricity on the "fan" setting as it does on the "cool" setting? [more inside]
My cooktop is shocking me. What's wrong? [more inside]
2 outlets & a ceiling light stopped working at the same time. None of the circuit breakers were flipped. What would cause this, and how can I troubleshoot it? [more inside]
Just a stupid question that's puzzled me for years: Why is it that, on electric fans, the order of the settings on the switch is OFF - HI - MED - LO? I'm sure there's an electrical reason for this, but I don't know what it is, since I know nothing about circuitry. One would think that OFF - LO - MED - HI would make more sense. Can someone explain this to me?
Electricity: I'm wiring up a new dishwasher with the power cord from the old dishwasher. Just to make things interesting, the power cord has absolutely no indication of which side is positive and which side is negative. Is this because it's AC and it doesn't matter? I'm in the US on 110.
If we can have wireless voice communication and wireless data transfer, why can't we have wireless electric current?
I have an old house with old wiring in the walls. The question inside is about installing window air conditioners. [more inside]
