Mark Twain, illuminated
From a 1895 article called Tesla's Osillator and Other Inventions, a photo of Mark Twain with one of Tesla's marvelous contraptions.
Thunder! Nah, nah, nah, nah, nah, nah,
Thunder! Nah, nah, nah, nah, nah, nah, nah, nah! Con Edison is cutting their last direct current line in NYC, ending 125 years of continuous service that started when Thomas Edison set up shop in 1882 and signaling the final triumph of alternating current in the AC/DC wars. (Lesson: Nikola Tesla always wins in the end.)
The last snip of Con Ed's direct current system will take place at 10 East 40th Street, near the Mid-Manhattan Library. That building, like the thousands of other direct current users that have been transitioned over the last several years, now has a converter installed on the premises that can take alternating electricity from the Con Ed power grid and adapt it on premises. Until now, Con Edison had been converting alternating to direct current for the customers who needed it -- old buildings on the Upper East Side and Upper West Side that used direct current for their elevators for example.
