Don’t buy stock in impossible space drives just yet:

When we hear terms like virtual particles and microwave resonators, our first thoughts turn to Chris Lee, our resident physics expert. We pointed Lee at the Wired UK article and set him loose. One of his first stops was at the webpages of a company that the article suggested was developing a similar thruster. In looking for details, Lee quickly headed for the company's "theory" page, which links to three pages on theory, mathematical modeling, and experimental results. All three links were dead. "Two of the three proof of concept pages 404 as well," Lee noted. The NASA report wasn't much help either, since it only delved into the practicalities of testing one of the devices. At first glance, however, it looked quite interesting, stating, "Approximately 30-50 micro-Newtons of thrust were recorded from an electric propulsion test article." If you push a bit further, it looks much less promising:

Thrust was observed on both test articles, even though one of the test articles was designed with the expectation that it would not produce thrust. Specifically, one test article contained internal physical modifications that were designed to produce thrust, while the other did not (with the latter being referred to as the "null" test article).

In other words, the negative control in the experiment worked. Which means that the experiment as a whole tells you nothing. Clearly, the device (even when disabled) appears to produce a force. But Lee suggested a variety of ways that this could happen and indicated that there are ways to monitor the device's operation to see if any of them play a role (for example, he suggested that a mass imbalance of as little as 3 mg could account for the small force the NASA researchers found. "All in all," Lee concluded, "it will take a lot more information before we can judge whether the thrust is really a thrust or not."

Even better - it doesn't even have to work to work.

I built a device that generates sunlight! For comparison, I ran a test on it alongside my control device that does not generate sunlight. Good news! There was sunlight for both devices! I'm a genius!

I hope this works. I don't know because it's over my head, but the VASIMR drive seems promising to me.

One way or another, we'll get out there eventually.

Runs on mercury, I bet.

They laughed at my phlogiston theory, but I'll show them! I'LL SHOW THEM ALL!
