Autonomous Maxwells Demon Displays Chilling Power

This is a few years old, but fun stuff to make your head spin. Finnish physicists are famous for their fantastic elegant experiments, and they were the first to produce an autonomous version of Maxwell’s Demon. They used a humble copper transistor and microscopic copper box to convert information directly into usable energy. Its as if they had simply waved a magic wand over their transistor, shouted “Abracadabra”, and empowered their transistor with the ability to convince unruly electrons to work out their own differences and be more productive. This has been compared to a self-powered quantum refrigerator and, theoretically, if you could entangle two of these, your home refrigerator could be powered by a generator in another country or even on Mars.

Another great example of “News of the Weird” coming out of experiments, is NASA is currently testing a Star Trek style “Reactionless Drive” that produces thrust in a vacuum without radiating anything or spitting anything out the back. Its basically a sealed microwave oven, not even a high powered one, that can cook your turkey in record time, and a nuclear powered spaceship using the technology could theoretically reach the moon in as little as four hours, Mars in a few weeks, and Jupiter in six months. Nobody has a damned clue how it works, but it has been tested in vacuum chambers and the first working prototype is going to be launched into space sometime soon.

The only plausible explanation given so far, that fits the evidence fairly well, is that the effect is related to Unruh radiation and quantum field theory. Field theory is the current foundation of modern Standard Theory in quantum mechanics, and implies that as you approach the speed of light, the vacuum of space itself transforms into radiation. A cold wood stove, for example, would progressively glow red until it disintegrated. Sometime in the next few years particle physicists expect to be able to test the effect in accelerators.
