I have a ten-year-old Sony TV that's on the fritz. It's a good enough second set that I'd like to save it if possible, but it's also big enough that it's going to be a pain to haul in to the shop for an estimate. If I decide to pop the case and dive inside for a quick sanity check, what do I need to do to avoid electrocuting myself in the process? [more inside]

New York City residents: Have you switched from Con Edison to another electricity and/or gas supplier under deregulation? If so, have you seen a significant difference in your bill, and how is the new provider's customer service? I'm trying to decide whether to switch to another provider (Econnergy, Energetix, etc.) for electricity, gas, or both.
I just picked up a 1000W step-down converter (220V-110V) to power a receiver after a 750W exploded in a blaze of glory when I turned it on one morning. I'd very much like to avoid this kind of thing again. So my question is, is it relatively safe to keep step-down converters turned on at all times? If so, will it constantly be using 1000W of power even when the receiver is turned off? I've heard differing opinions but found no definitive answer on the interwebs. Related, is it true that you should always have something plugged into the converter when it is turned on?
I have two Nokia mobile phones - one purchased in the US and one that I've purchased here in Indonesia, both with their own similar-looking chargers (though with obvious differences on the plugs). Can I charge the Indonesian phone in the US on the US charger? [more inside]

After a last minute sale of my condo, the deal on the house I bought closes on Thursday. I need to arrange for utilities, insurance, and some repairs, and have next-to-no time to do research. If you have a satisfactory provider of any of these things and said provider's services are available to a Torontonian, recommend away! And of course I'll think of you all when I'm doing my happy dance on my rooftop terrace;-) [more inside]

I live in a hundred-year old house (in Los Angeles, no less!) that has limited electrical outlets. I have unlimited (it seems) electronics - three computers, monitors, two laser printers, two air conditioners, electric heater (in the winter), etc. The house was upgraded from old-style fuses to circuit breakers a few years ago. It is a rental so I am not able to do any upgrades. None of the wall outlets are three prong, so I am using adapters. In the summer, my office is just overdone with things drawing power - all three computers, the printers, AC, and probably 20 (or more) smaller items - cell phone, postage scale, radio, etc....

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]

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?
