Turning 17 watts of microwave power into 40-91 micronewtons of thrust isn't exactly stunning, though.
- idlewords 11y agoAnother data point: my kitchen microwave has been getting 32 millimeters to the hot pocket.
- baq 11y agofrom the wikipedia ion thruster article: > Ion thrusters have an input power spanning 1–7 kilowatts, exhaust velocity 20–50 kilometers per second, thrust 20–250 millinewtons and efficiency 60–80%.[1][2] 3 orders of magnitude less thrust than for not needing to accelerate any fuel all the way into orbit? i'll tell you space companies will send trucks full of money to anyone who can make a reliable one.
