One of the zones in my outdoor sprinkler isn't working, caused it appears by a malfunctioning solenoid valve. I spent the morning learning how to inspect, repair and/or replace it, and I'm about to do so, but I am unsure as to whether electricity is running to it. How can I know? [more inside]

TV on all the time

Craigslist HD TV deal..it was $25. The rub being it "doesn't always turn on". The first week it was fine. Then it started not turning on until later in the evening. The boyfriend (possibly) diagnosed the problem and will attempt to fix it when it becomes absolutely necessary. However, until then we are leaving it on all the time. [more inside]

Where are companies building power-hungry datacenters to take advantage of cheap power?

Is there a list of datacenter projects that have been built from a green-field state to take advantage of a guaranteed low per kilowatt-hour electrical rate? In particular I'm thinking of the big Google facility near The Dalles, Oregon and the Microsoft datacenter in a small eastern Washington town. Both were built in areas with excess capacity originally intended to serve large Aluminum smelters. [more inside]

Do I really need to physically unplug my Xbox 360 when not in use?

On one of the morning "news" shows (Today, GMA, one of those, don't remember which), a guest recently said that an Xbox 360 or Playstation 3 will use just as much power turned off as it does when in use - that you have to physically unplug them to get them to stop draining the juice. The Wii, it was said, is fundamentally different, has some kinda internal widget that makes it more energy efficient. Any truth at all to this?

Is my new (aftermarket) power adapter safe for my laptop?

Can I damage my laptop by using a power adapter that has a slightly higher wattage than the original adapter? The original adapter was 65W, and the aftermarket one is 70W. The voltage is switchable. My original adapter had a voltage of 18.5V, this one says that if I need 18.5V, I should choose 18V. Any chance of damaging the computer by using this one? [more inside]

When exactly did the city of New Orleans lose power during Hurricane Katrina?

I'm trying to find out the date and time that the city of New Orleans lost power during Hurricane Katrina. A customer service representative at Entergy told me that it was staggered throughout the morning of August 29th, the day the storm hit Louisiana, but I would really love more specific information. After searching news archives and situation reports, all I've found so far is that the Superdome lost power at 5am that same morning. Where can I find the time and date?

Sun as electrical plasma

Having watched Thunderbolts of the Gods, and found it quite eye-opening, I'm wondering if there are compelling reasons to accept or not to accept the possibility that the Sun is made of electrical plasma, rather than being a nuclear furnace.
