Was Thomas Edison Right about DC Power?
Declan McCullagh writes "Everyone knows the alternating vs. direct current wars ended with Thomas Edison and Nikola Tesla. But now DC power is being seriously considered for data centers. DC advocates say that plugging servers into AC power is inefficient, and switching to DC cuts down on waste heat and component failure. The University of Florida has even bought 200 DC servers."
OTTH (On the third hand...) if your skin is sweaty, it conducts a lot better than when it is dry. Enough better that enough current flows to dissipate enough power to heat your skin past the point where you suffer burns. Or worse.
