The electric charge and voltage are both important. Voltage vice 60V can kill but you would need a large charge/high current. Anyway a PSU can store potentially deadly charges for a while (there are large capacitors that can store such charges and coils in a transformator setup that can potentially up or down transform the initial voltage at the capacitors).

Actually in such a case its more likely that grounding kills you. When you work with PC components there is a warning to properly ground yourself before installing it. But thats not for your safety but the safety of the hardware.

What kills you is when there is a deadly discharge using your body as grounding wire (as a conductor). Only if there is a current flowing through your body you will actually be in danger. So, if you were completely isolated (not grounded), you would charge up to the voltage level of the voltage source and thats it (however there will still be a charging current - but it is not as potentially deadly as the current that will be subjected to you when you are grounded).

The next question is, where does the current flow. When it flows from finger to arm to torso to leg to feet, then you will cover a lot of organs to damage in the current's way. If you were grounded directly at your arm or finger, the current would flow more localy in these body parts and has a lesser potential to damage vital organs.

Which is why the "wrist strap groundy thing" is actually a Good Idea (except I rarely see anyone putting them on both wrists )

I am no expert in electronics but is there a need to store that much energy that isn't doing anything at all?

Someday I figure someone going use PSUs to make bombs.

NATO says it's ready to back Turkey

Largely a symbolic gesture.. NATO really doesn't want to get involved and Turkey has its own fighter jets and military machine..

The "purpose" is to create safe, SMOOTH, electrical power for those delicate modern computer circuits. (note that I capitalized SMOOTH ).

And you can make bombs out of almost anything in your house, small appliances included.

Relevant xkcd.

I'm still annoyed they took away my water bottle last time I flew. Guys, what about my cellphone?

Bomb risk to U.S. troops heightened by contractor fraud
http://www.reuters.com/article/2012/...89A1CY20121011
I am suprised than it wasn't a US contractor than had the job.

This ... is the pit of the "military-industrial complex" -- that the defense department exists purely for corporations to siphon money out of the federal budget and to eliminate oversight or accountability. Whenever you hear conservatives blather on about "privatization", this is the nasty little goblin under the table biting your shorts.

I'm not inherently against privatizing specific functions but it MUST come with government citizen-accountable oversight or its just the barons looting the treasury again.

The Bush administration spent 2000-2008 "privatizing" every government agency they could ... and eliminating the agencies ability/budget to perform oversight. That's why I said in 2008 it might take as long as 10 years to repair the damage done to all the agencies from the FDA to the Interior to, yes, the Defense Department.

Go find this manual named "Improvised Munitions Handbook", it is an official print that is distributed to the US combat troops during the Vietnam War.

Anything can be turned into a lethal weapon - your brain is the ultimate toolbox. Use it wisely.

Most of all, you have to be disciplined and you have to save, even if you hate our current financial system. Because if you don't save, then you're guaranteed to end up with nothing.

it is a good thing or bad thing that so many posters are so familiar with the manufacture of improvise explosives and most of us don't even have the excuse of living through the 60s.

Jinto and I had military training. Vexx is ex-MIB. Not sure about the rest.

Coming from a military family which also produces explosives, never mind the papers, one can be a bit informed.

Qur'an-burning Florida pastor denied entry to Canada

Quote:
Florida pastor Terry Jones, who inflamed Muslims by once burning the Qur'an, says he has been denied permission to enter Canada to attend a Thursday evening speaking engagement in Toronto.

Jones told CBC News he may appeal. But for the time being, he said he would head back to Florida.

The Canada Border Services Agency made Jones go through a secondary inspection when he arrived at the Ambassador Bridge in Windsor, Ont., around noon. Secondary inspection involves a search of a person's vehicle and more extensive questioning.
