Science Fiction gradually becomes practical technology

There's no telling whether this technology will scale up to the point where palettes of household goods can be easily moved around a warehouse (or the galaxy), but it is interesting to speculate about.

Physicists have 'solved' mystery of levitation - Telegraph:
"Levitation has been elevated from being pure science fiction to science fact, according to a study reported today by physicists. In theory the discovery could be used to levitate a person In earlier work the same team of theoretical physicists showed that invisibility cloaks are feasible."

In general, practical technology scales up and/or the costs fall dramatically. This doesn't always happen at the same rate for every technology. For example, a modern car offers far more features for a lower portion of the average annual income than in the 1950s, but if the cost of cars tracked to the cost of computers, we could all afford a choice of cars to drive for every day of the week.

It will be interesting to see if the levitation technology depends on rare metals and compounds or if like computers the cost is primarily intellectual property . . . Remember Jerry Pournelle's observation that "steel is expensive, sand (silicon) is cheap".
