That's right, Chuck. I thought the effect of tasers was well represented in "The Hangover."

Yes, judging by some recent news videos I've seen, tasers can occasionally be used a little too cavalierly.

Chuck, I think that's a good idea that police officers have to be tazed before they start to taze others.

Good point, armorris. Medical cardioversion typically uses fairly high voltage, with extremely low currents (in the mA range). On the surface, the low currents would appear to be benign, but coupled with a high voltage (100 V to 700V, as I understand), it's enough to stop a person's heart and allow it to re-set. So while it's true it doesn't kill the patient, it does stop the heart momentarily. Maybe a reader who designs these devices can weigh in with more (and better) information.

Thanks for the info, AWltom. I'm amazed they did that. I quickly looked on Amazon for a stun gun, saw the 14,000,000 V part number and assumed they were claiming that it was 14 million Volts. It's clearly a marketing ploy, and I'm sure I'm not the only one who made that ssumption.

I did not have my hand up, Rob. The reporter who volunteered also allowed it to be filmed by a crew, and I think he was sorry he did. The Wall Street Journal actually posted it on their web site for awhile, but then they pulled it down, which was a good move. By the way, I have a nephew who's an Oakland police officer, and I believe he had to be tazed as part of his training.

High voltage is definitely dangerous when there is high current available. Ohms Law says that voltage is required to get current to flow through a resistance. You should never disregard a "High Voltage" sign.

A Van De Graaff generator produces a lot of voltage, but with very little available current. A stun gun also produces relatively small current. It can cause paralysis or pain, but produces no harm unless it passes through the heart, causing fibrillation.

Reminds me of the toy company that named their stacking brick toys 0937. In the right font it spelled LEGO, upside down. What a coincidence...

I can't believe someone would volunteer to be tazed, Chuck. I woiuld imagine you didn't have your hand up.

Latest Analysis
From home enthusiasts to workers on the manufacturing floor, everyone's imagination is captured by the potential of 3D printing. Prototyping, spare parts creation, art delivery, human organ creation, and even mass product production are all being targeted as current and potential uses for the technology.
ABI Research, a firm based in the UK that specializes in analyzing global connectivity and other emerging technologies, estimates there will be 40.9 billion active wirelessly interconnected “things” by 2020. The driving force is the usual suspect: the Internet of Things.
Just in time for Earth Day, chemicals leader Bayer MaterialScience reported from the UTECH Europe 2015 polyurethane show on programs and applications using its materials to help reduce energy usage. The company also gave an update on its CO2-based PU as that eco-friendly material comes closer to production.
Solar and wind energy are becoming more viable as a source of energy on the electric grid. For decades, the major drawback to solar and wind was that they’re temperamental. A cloudy day kills solar and a still day renders the wind turbines useless. Automation tools, however, are providing a path to help these renewables become practical.
In honor of Earth Day, the National Security Agency has launched the STEM Recycling Challenge in Maryland schools to encourage kids to think about where the garbage they throw out every day actually goes. The agency has also introduced “Dunk,” a muscular blue cartoon recycling bin wearing shorts and sneakers.
