How do dams hurt rivers, exactly? Is that damage built in – that is, are there ways to mitigate it? On the other hand, do a few million people deserve electricity?
Looking for reasoned arguments. Caveat: solar power is reasonable, but I don't see it replacing the Aswan dam in the next few generations.

I live in Atlantic Canada, and in the past year significant, long lasting power outages have become extremely common. We can't afford a generator. What other things would may family and I most benefit from, and what is the best/most reliable ways to power devices? I have a limited budget so we're talking bang for your buck. [more inside]

Can I take a Cintiq digitiser tablet through airport screening without getting it confiscated? The Cintiq requires mains power to work. (It doesn't have a battery, & was never designed to work with one). I think it's understandable that I wouldn't want to check this in as hold baggage. It's easy to mistake the thing for a tablet that "suspiciously does nothing" when not plugged in to the wall. UK-US trip. [more inside]

While installing a new car stereo in my 1999 Saturn SW2, I screwed something up, as I no longer get voltage to the orange "constant power" wire (well, sometimes a mere hundredth of a volt!) to my car stereo, and my engine won't crank either! Yet all of my other electronics (headlights, air conditioner, etc.) work fine. Is there a blown fuse preventing power from getting to the starter and the car stereo? If so, where might the fuse be? The fuses in the fuse box are all fine.

I currently own an Oral B electric toothbrush with charger unit #3757, 110-130V, 1.3W. I'm moving to Malaysia soon which has the 240V/50Hz power, so I got someone to bring me a new fancy Oral B from the UK which has the same electric supply. This comes with a charger that is also labeled #3757 but says 220-240V 0.9W. So my question is, can I safely charge the new toothbrush with the old charger until I leave the US? Or will the slightly higher powered charger fry it?

I graduated with an M.A. in English and through luck, contracting, and family connections, came to work in nuclear power. My administrative role has changed to field work. I prefer office work, especially writing reports etc. My area in nuclear is very specialized, and due to downsizing in the industry, I feel a real need to get familiar with my prospects for other jobs and diversify my skills. However, I have no idea how to begin, research being one of my weak points. Long explanation + details inside. [more inside]

I don't really understand the utility industry very much but I've noticed some electric companies are very responsive to getting lines up from damage and have crews out at 2 a.m., and others don't even start work until the next day. What motivates them? Is it primarily loss of earnings from all the meters not running? Are there regulatory performance expectations? Or is there some sort of precedent in litigation that would put them at fault for underperforming? [more inside]

My friend has an HSBC Mexico account, that had about 40,000 dollars in it.. he didn't use the account for a year, he called today to get a new checkbook, and found out the account had zero balance in may of 2013, and the account was closed. HSBC Mexico said they can't give more information unless he goes in person to a branch in Mexico. He is willing to hire a lawyer, or Power of attorney, or someone to investigate this in Mexico who legally represent him. He is currently far from mexico and can't make it there any time soon. His mom is in Mexico, can she get power of attorney? Any advice on how to do this? How can he go about finding a lawyer in Mexico who can help him? Or what actions can he take? He suspects fraudulent activity as he did login to his internet banking last year and saw all his money there.

I saw an incredibly concise quote floating around social media a few weeks back that described how hierarchy becomes self-perpetuating. The gist of it was that those at the top of a hierarchy deprive those below them of the practice required to conceptualize and implement their own plans, and then turn around and justify their position by pointing out how incapable their subordinates have become.
I'm almost certain the person quoted was female, and I'm fairly sure she was a social sciences academic, but may have been an activist of some stripe.

There was a huge lightning storm this morning, in the middle of it my power went out.
All the breakers on my boat are on, all e breakers on the power bollard are on.
The odd thing is that the bollard has power to the meters and register 5v on the ac setting of my multimeter across live and earth.
Also the RCD buttons trip out the breakers. This suggests that it has power. But nothings coming out.
Any ideas for
a) How come it has some power but no output
b) Is there anything I can do.
My electrical skills = I own a nice multimeter
My fear of zappy death = relatively high [more inside]

Help me with my ten year old sons school project !
I'd like to find people - as well known as possible - to whom the adage "power tends to corrupt, absolute power corrupts absolutely" .
So an ideal example would be someone who started off with good intentions and then on gaining power started behaving poorly . Also ideally once they'd turned nasty their actions would not be so despicable that you wouldn't mind explaining them to a ten year old

My daughter has a Yamaha psr-260 that we picked up at a garage sale. It did not have a power supply and used batteries to power up.
Since the batteries have died, I have found a power supply that seems to match the piano's requirements on the back of the unit: DC IN 10-12V.
The power supply says Input: AC 120V 60 Hz 20W and Output: DC 12V 1000mA with a matching polarity symbol (the plus is inside the minus). [more inside]

My Windows 7 computer no longer turns off properly. If I shut the screen, it no longer sleeps or hibernates, it just freezes. If I go through the start menu to hibernate, it will do so, but the computer is still on -- the power and the wifi lights stay on, it's still running and using battery. This also happens if I go through the start menu to turn off the computer. If I hold on the power key, it will then turn off and restart or resume from hibernation normally when I turn it back on.

I'm a Sandy refugee, living with friends until my power's restored (latest estimate: 11/9). There's got to be a way to remotely detect that - to sniff for current in an AC plug, or detect light from a bulb or the reestablishment of my WiFi network....and then use the WiFi to let me know. The tech would be trivial. Does anything like that (aside from $$$ home monitoring set-ups) exist? Or could I rig one up?

I've read about 50,000,000 assorted peices of dating advice and there's one rule that I've followed religiously: Girls (who want LTRs) Should Never Ask Out Guys. This advice has some seemingly-reasonable justifications backing it up. You can respond to the justifications or skip the whole thing and just tell me whether or not it's legit. I would especially like to hear from men about this. Have you ever willingly entered a happy, functional, long-lasting relationship with a girl who asked YOU out? [more inside]
