I've been living in my apartment since December, and I still haven't received an electric bill from ConEd. It was made clear that we had to sign up to receive power and we did that -- my wife called in, gave them her social security number, address, etc. Still, no bill. The meter man comes by every month and checks the meter. Still, no bill. [more inside]

On our property there's a rather substantial brook running through it, which runs year round and doesn't freeze over. It's probably too wide for a traditional undershot waterwheel (at least 12 feet across at its most narrow), to supply some alternate power to our house, but maybe there's something else that could make the most of the constant flowing water?

I'm looking for a book that teaches electricity well
. The Mims
book definitely doesn't cut it - I want something more along the lines of "The Way Things Work
" in clarity and accessibility, but I still want it to actually teach the underlying math; i.e., I want it to show me the material in pictures and
equations. [more inside]

Please help me find this great picture of electrical arcs. I saw this photo a while back. I'm pretty sure it was in a magazine. It was of a great big round room, with some sort of large apparatus, like a collider or something (it wasn't a collider I don't think). There were scaffolding and cat walks running everywhere. Lots of pipes and fittings. Everything was gold or copper or something. And the entire room is covered in arcs of electricity. Great big bolts running all around the room, with smaller and smaller branches and fingers breaking off to fill up every metal surface area with arcs. It was some sort of electrical discharge as a result of the experiment that was being run. I can't remember what it was, so I don't even know what to look for in Google. Any help would be appreciated. Even just a guess as to what the device was that would produce that, so I have a starting point to try and find it. Thanks.

How much does it cost (or what is the amount of electricity / volume of water used) to do one full load of laundry, as an average. Or, how would I go about getting precise figures for this? I want to know how much too much we pay to operate the pay-per-load laundry machines in our new apartment building.

I have two computers, each with something like 350W power supplies. By keeping them on 24/7, am I consuming the equivalent of seven 100-watt light bulbs around the clock? What can I do (either software or hardware) to make my machines more power-efficient?
Also - while I'm on the subject - does an incandescent bulb consume less when it's on a dimmer and that dimmer is turned down? [more inside]

Searching for a home, my girlfriend and I have found a house we want to make an offer on. It's our dream house in a nice town, but there's an issue... the house sits about 100 yards away from this
... a relatively small power distribution/transfer station adjacent to the property. Do we have anything to be concerned about or should I go buy some lead boxer shorts? [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?

I just replaced a burned out bulb in my overhead kitchen fixture. The bulb that burned out was a 60 watter. I only had a 100 watter on hand. I know I'm hastening fossil fuel depletion, but am I also causing a fire risk? What about ignoring the wattage recomendations in favor of higher watts in table lamps?

If I have AC power at 50Hz, does it mean my lightbulb is flickering 100 times a second and I just can't see it? Is this why, when passing a street light in a speeding train, it can appear as a series of dots in your vision?

The lights in my house occasionally pulse--that is, they'll rapidly get noticeably dimmer and brighter numerous times within a matter of just a few seconds. I'd say "flicker," but they never seem to actually go completely dark. Does this indicate faulty wiring, or something else? [more inside]

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.

TransformerFilter: I've just relocated to the US and have a rechargeable drill that uses a 17V DC transformer. I need to replace the transformer, since the one I have runs on 240V power (and has the UK prongs). The problem here is that I can't find a suitable replacement at the likely suspect places: hardware stores, Radio Shack...
I know that the voltage must match precisely and that the amperage must be at least as high as the noted amperage, and that the polarity must also match. So where can I go to find a good transformer? I'm in NYC, but I prefer to shop online.
