8. Mmmm. Not quite. Electricity is not the fuel. Satellites are not the only anticipated application.

Here are a few other articles covering it. None of them characterize electricity as the "fuel" and each points out the potential for long-distance spaceflight.

NASA confirms microwave space drive is possible, fuel-free propulsion incoming

In short, if the results hold up, humanity can say goodbye to huge energy consumption costs associated with space travel, and say hello to deep-space missions and distant world exploration at a fraction of the cost and at 100 times the speed.

But since its inception, the revolutionary drive had appeared to be impossible because it breaks the laws of the conservation of momentum. Put simply, acceleration in any rocket engine is achieved by a large amount of fuel bursting out of the thrusters and pushing the vessel forward. The drive promises to change this forever by creating its own momentum.

NASA confirms fuel-free space drive that uses microwaves to fly
NASA said: "Test results indicate that the RF resonant cavity thruster design, which is unique as an electric propulsion device, is producing a force that is not attributable to any classical electromagnetic phenomenon and therefore is potentially demonstrating an interaction with the quantum vacuum virtual plasma."

With artificial leaves shown off this week and now fuel-free drives possible it's starting to look like deep space travel may soon become a reality.


The article cited is actually one of the few that tries to provide a realistic explanation of what's going on. The inventors of these drives are talking about "bouncing microwaves around inside a closed container to create thrust." But thrust from what? What is being pushed out of the drive to move the vehicle? "Electricity" cannot by itself create thrust.

Wild as it would be, particles spontaneously appearing inside the drive due to quantum phenonemon at least would not shred the conservation of matter / energy.

It would, however, be essentially "perpetual," given the device is neither carrying nor actively collecting fuel.

IF, of course, no is fueling themselves (yukka yukka) about what's going on here.
