It's Nikola Tesla's 153rd birthday. In that century and a half he has gone from genius to kook to genius again. Electrical engineers are just beginning to get their heads around his concept of wireless energy transmission. The upshot being that you may soon be able to power your laptop without plugging it in. He is presently thought of so highly by the corporate world that Google has posted this special birthday logo today, and
a car company has taken his name.
