Help me not get painful static shocks to my hands at Costco please.

I get painful static shocks to my hands where they touch the cart as I'm pushing it around at Costco. As far as I can tell this happens while wearing various kinds of shoes, although I haven't experimented rigorously. Help me devise a method to prevent this that I can realistically implement during impromptu trips to the store. [more inside]

Help my iguana survive Frankenstorm

How do I keep my iguana alive during an electric blackout? All of her lighting and heating elements demand electricity. I don't have a generator or the funds to purchase one. I'm most concerned about her getting too cold. Under 80*F for extended periods is the danger zone.

Power's out, how long will the cold last?

Power went out... right as I'd gone to the grocery. I put all the must-stay-cold stuff away anyhow because the stuff I'd bought was worth more than what was already in there. So, it's been opened once, what was put in was still frozen/cold from the grocery. I'm not opening it again. How long can I expect stuff to still be good for? [more inside]

Switch doesn't switch correctly.

Please help me understand this bizarre home electrical-wiring problem, and how to fix it. I've got a mid-50s house.

Is my power green?

In 2009, 91.2% of Seattle's electricity was from hydroelectric sources, and in 2010, 87.9% was hydro. Is the hydro capacity maxed out, or will it scale up to meet additional demand and maintain that ratio? Here's what I'm getting at: If I were to use more electricity than now, will that incremental power effectively come from non-renewable sources rather than ~90% hydro?

What device is used to regulate power over several circuits?

A friend of mine has 20+ old arcade games in his basement. He has essentially set up a small arcade museum at his house. It's pretty sweet! The games are split between several circuits in the house but power is becoming a concern. These old electronics are sensitive to spikes and low voltages and we want to keep them running as long as possible - most of the circuit boards are not made and difficult to replace or repair. What should we consider for 110v line conditioning? [more inside]
