IT, the mysterious invention from Dean Kamen thought to be a revolutionary personal transportation device, is set to be unveiled on Monday’s Good Morning America, according to Reuters. Kamen will reportedly detail the device in both television and newspaper interviews early next week. The most popular theory is that IT is some sort of personal hovercraft that relies on an emission-free Stirling engine that recycles much of its own heat. Apple CEO Steve Jobs and Amazon CEO Jeff Bezos are among the handful of people who have seen the device—both had high praise for the revolutionary invention.
