The power in our downstairs is out but there are no breakers in the fuse panel showing red. Can any electricians out there 'shed some light' (groan....) ???? [more inside]
I understand that incandescent light bulbs are antiquated and extremely wasteful, but LED and fluorescent light looks horrible... [more inside]
Why is my electricty going on and off? It's not a blown fuse/circuit because it comes back on again. What would cause this? What should I tell an electrician to do in order to get them to fix the problem? [more inside]
My old electric hot water service has sprung a leak, and I'm researching replacement options. Is there anything greener and more cost-effective available to this Australian than off-peak electric? [more inside]

Physics filter: The original fuse for an Ikea lighting system was rated for 6.3A and 250V. After a power surge, I noticed that the fuse had been toasted. Upon visiting 3 hardware stores, the best I could find was a similar fuse rated for 3.15A and 125V. Since V=I*R, it follows that the resistance is identical when the original fuse is compared with the replacement. Does this mean that these fuses are functionally equal?
How do electric meters work? How do they measure the amount of charge you used? I suspect they must know the amount of charge that enters the home, and then they have some way to measure the amount of charge that leaves the house, but I'm really not sure. [more inside]

EnergyPurchaseFilter: What is the deal with non-regulated electric purchasing? Who's had experience with this, and was it all the [highly suspect] awesome hoopla that it's played to be by the companies/government? Bonus points if you live/have lived in New Hampshire, where I'm trying to figure out this whole mess. [more inside]
In the UK we have cheap rate electricity between 12.30am and 7.30am, but how does it work? [more inside]
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?

Cat Filter - In the winter the static electricity gets in the way of the cat & my... well... lets just say personal time. Any advice? [more inside]
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.

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.

SolarPowerFilter: My wife and I love the idea of solar power and would love to compliment our current electrical consumption with some tasty renewable energy, but where do we start? [more inside]
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.
Why is it that if I walk up and stick my finger in a wall outlet, I'll get shocked even though I'm not grounded? I can see getting shocked when standing barefoot on wet ground, but come on... on a floor wearing tennis shoes? How does that work?
My boyfriend and I live in a flat built in the '20s. We have reason to suspect that the outlets provide inconsistent amount of electrical current. Is there something we need to get for our computers to protect them? [more inside]
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]
Living near power lines? 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]
