from globalwarming-arclein.blogspot.ca: The world of the insanely small is arriving. Practical applications may not even be obvious yet, but this is one of those moments in which you go build it and people will come... In the 1966 film “Fantastic Voyage,” a submarine, full of scientists, is shrunk to microscopic size and injected into the bloodstream of a seriously wounded diplomat. Forty-six years later, the idea sounds less far fetched. In a Stanford lab, engineers are perfecting their fantastic voyage. And then, we can make it smaller,” said electrical engineer Professor Ada Poon, Ph.D... Instead of a battery, which takes up lots of space, the device that will be used for travel is powered wirelessly with electromagnetic radio waves. The result is a new class of medical devices that are so small they can travel through the bloodstream. “Right now we could go to the arteries...but we want it to even go through some smaller bloodstreams,” said Poon.
