It might look good and it might tickle the fancy of UFO believers, but there are so may reasons why the design is inefficient. For example, using downward thrust to keep a heavy object afloat takes tremendoes amounts of torque, and the problem is, the engine "treads air". It pushes the thrust out so fast it creates it's own envelope. If they could have used the princible of the helicopter rotor, where the torques is spread across a large area, then maybe it would fly. Another reason is that they want the outer ring to spin creating a gyro effect. There are huge amounts of energy lost there. Another example that should have been taken from the helicopter.

Not only did they develop a system for propulsion with a laser beam, but they have developed a Xenon-ion electrostatic propulsion system that can propel the craft at 77,000 mph with a force of the weight of a piece of paper.
