		<description>Well, there &lt;em&gt;is&lt;/em&gt; no aether, so this isn&#039;t going to work classically.

But maybe you could play around with the quantum vacuum. Unlike the classical vacuum (which really is empty), the quantum vacuum has energy. It&#039;s the sum of the zero-point energy levels of all the quantum fields in the region. There&#039;s not very much energy there, but there is a little -- maybe even enough to propel a tiny propeller?

Interesting thought.</description>
