From The Inquirer: US grants patent for anti-gravity device:
“ACCUSATIONS that the US Patent office is giving out dotty patents were given some credence this week after the magazine Nature discovered that the watchdog had just granted one to a bloke who claimed to have invented an anti-gravity machine.
Boris Volfson, of Huntington, is the proud holder of patent 6,960,975, which is for a space vehicle propelled by a superconducting shield that alters the curvature of space-time outside the craft in a way that counteracts gravity.”
No word on whether it has to be constructed from transparent aluminum.
