Flying carpet to Pluto?

Check out "Will a flying carpet take us to Pluto?" in New Scientist. I thought it is yet another solar sail idea with a catchy name, then I realized there is something new. The “flying carpet” is a flexible array of solar-powered ion engines. The presented design doesn't use rigid supports––the carpet is extended by vector-control of the engines. The spacecraft can be carried by space shuttles and then unfurled in orbit. It could reach Pluto in 80 days and to Sedna (the newly found “10th planet”) in 2 years. Sounds cool, but there is no such a carpet and won’t be available for quite a while. Luckily we just need the area enough to cover one end zone of a football field.
