Today's the anniversary of Thomas Edison's vicious electrocution of a live elephant in order to prove the dangers of Nikola Tesla's alternating current and the safety of his competing direct current.
When the day came, Topsy was restrained using a ship's hawser fastened on one end to a donkey engine and on the other to a post. Wooden sandals with copper electrodes were attached to her feet and a copper wire run to Edison's electric light plant, where his technicians awaited the go-ahead.
In order to make sure that Topsy emerged from this spectacle more than just singed and angry, she was fed cyanide-laced carrots moments before a 6,600-volt AC charge slammed through her body. Officials needn't have worried. Topsy was killed instantly and Edison, in his mind anyway, had proved his point.
A crowd put at 1,500 witnessed Topsy's execution, which was filmed by Edison and released later that year as Electrocuting an Elephant.

Thinking of a business idea is the easy part. Doesn’t even have to be a “good” idea, you can still get people to throw money at a non-existent venture, but to do that you need to at least have something even resembling a viable business plan. Why doesn’t anyone do it then? Because building that semi-viable […]
