Yogi,

But a Danish physicist and her team of collaborators have found a way to slow light down to about 38 miles an hour, a speed exceeded by a strong bicyclist.

As I have considered myself a good cyclist at times in my life,I had to laugh at the comparison. Greg LeMonde in his remarkable win at the Tour de France won the final time trial at a blistering pace of about 33 mph over approximately 50 miles. (If memory serves)

I would need a substantial hill to exceed 38 mph for more than a brief moment. <gasp>

Yogi, now that's got potential >"We're getting the speed of light so low we can almost send a beam into the system, go for a cup of
coffee and return in time to see the light come out," Dr. Hau said in an interview.

Thanks Yogi. I suspect this quote is on the optimistic side:
>>Although Dr. Hau said it might take 10 years before major applications were developed, the huge refractive index of the condensate, which can be precisely controlled, may make it a basis for "up shifting" devices that increase the frequencies of light beams from the infrared end of the spectrum up through visible light to ultraviolet. Possible applications include ultrasensitive night-vision glasses and laser light projectors that could create very bright projected images.<<

I recall seeing the High Temperature Superconducting demonstration in on "The Late Show with Johnny Carson" with levitating magnets and such. These breakthroughs are fascinating but the practical applications seem slow in developing.
