The spark of invention

Seventy years after his death, the mystery sυrrουnding electrical engineer Nikola Tesla - particularly his claim to have invented a ´death ray´ - is s arking the imagination of movie makers. There´s a car company named after him. And an airport, a telecommunications group, a computer graphics processor, a social transformation conference, even a rock band.
