If you keeping making comments like this one day I'm going to be tempted to try and sneak in a post on the history of zero-point energy.

In the meantime, you might find these videos amusing - apparently a perpetual motion vehicle is already available :-)

Has that got something to do with Feng Shui?

April Fools day ?

No - its an English tradition...
