ok, i'll shut up now.

It could be useful for a lot of high-tech things like microscopes, observatory telescopes and fiber-optic cables, though. Maybe it could also be used to make special focusing lenses for lasers or something too.]]>May 2nd 2006 4:04PMhttp://www.engadget.com/2006/05/02/japanese-reseachers-invent-completely-transparent-material/http://www.engadget.com/2006/05/02/japanese-reseachers-invent-completely-transparent-material/2) Negative refractivity is a different concept, notice that refractivity depends on the square root of permittivity and permeability, which are positive values in ordinary tranparent material. If the ratio is negative, then there is something in the material that propagates or channels the wave, which exactly the gold waveguides does. In a completely transparent material the speed of light does not change in medium, thus n=1, and compex counterpart k is 0. Optical equipment is possible, by playing with the waveguide.
3) From wikipedia: The first Superlens (an optical lens employing negative refraction with vastly improved microscopic resolution) was created and demonstrated in 2005 by Xiang Zhang et al of UC Berkeley, as reported in the April 22 issue of the journal Science [1]

Although this is state of the art nanotechnology, don't give up your hope yet, transparent aliminum would still be a bigger achievment.]]>May 2nd 2006 4:04PMhttp://www.engadget.com/2006/05/02/japanese-reseachers-invent-completely-transparent-material/http://www.engadget.com/2006/05/02/japanese-reseachers-invent-completely-transparent-material/
However, that might have been with optical amplifiers. If you could get rid of those, then long-distance fiber would be even cheaper.]]>May 2nd 2006 4:11PMhttp://www.engadget.com/2006/05/02/japanese-reseachers-invent-completely-transparent-material/http://www.engadget.com/2006/05/02/japanese-reseachers-invent-completely-transparent-material/no, not quite. from http://physics.ucsd.edu/lhmedia/ :
"As an example, a lens made from LHM that would be converging if made from conventional material, will be diverging, and vice-versa. Also, a thick flat plate (window) of LHM can focus radiation from a point source back to a point."

so you could make glasses out it, but the curve needed would opposite of conventional glass, allowing certain very thick glasses to be made with much thiner and lighter material.

A 100% transparent material would essentially be invisible, as it would allow all light to pass through it. We can see objects, because light reflects off of them. Perhaps you were thinking of "translucent".]]>May 2nd 2006 6:55PMhttp://www.engadget.com/2006/05/02/japanese-reseachers-invent-completely-transparent-material/http://www.engadget.com/2006/05/02/japanese-reseachers-invent-completely-transparent-material/May 2nd 2006 7:13PMhttp://www.engadget.com/2006/05/02/japanese-reseachers-invent-completely-transparent-material/http://www.engadget.com/2006/05/02/japanese-reseachers-invent-completely-transparent-material/May 2nd 2006 7:32PMhttp://www.engadget.com/2006/05/02/japanese-reseachers-invent-completely-transparent-material/http://www.engadget.com/2006/05/02/japanese-reseachers-invent-completely-transparent-material/
