A real space drive?

If this pans out, and the preliminary results are encouraging, we may actually have a working space drive that will put the whole solar system within reach: Nasa [sic] validates 'impossible' space drive [link fixed].

Either the results are completely wrong, or Nasa has confirmed a major breakthrough in space propulsion. . . . British scientist Roger Shawyer has been trying to interest people in his EmDrive for some years through his company SPR Ltd. Shawyer claims the EmDrive converts electric power into thrust, without the need for any propellant by bouncing microwaves around in a closed container. . . .

[L]ast year . . . a Chinese team built its own EmDrive [ and confirmed that it produced 720 mN (about 72 grams) of thrust, enough for a practical satellite thruster. . . .

[A] US scientist, Guido Fetta, has built his own propellant-less microwave thruster, and managed to persuade Nasa to test it out. The test results were presented on July 30 at the 50th Joint Propulsion Conference in Cleveland, Ohio. Astonishingly enough, they are positive. . . .

A working microwave thruster would radically cut the cost of satellites and space stations and extend their working life, drive deep-space missions, and take astronauts to Mars in weeks rather than months.

Who knows: I might live at least to see people explore the solar system!
