Parece mucha, pero, ¿habeis pensado que actualmente ya teneis un laser en vuestra grabadora que hace algo muy parecido (incluso es posible que a mayor temperatura)?:

The DVD's recording layer is made of a crystalline, phase-change alloy, usually Ag-In-Sb-Te. In its original state, the layer is polycrystalline and has high reflectivity. To write data, a focused laser beam heats areas of "marks" in the phase-change material above the melting temperature (500-700°C). The atoms in this area become liquid. If cooled quickly, the random, non-crystalline liquid state is 'frozen,' leaving the area in an amorphous, low-reflectivity state which leaves dark pits on the DVD disk. The area between marks, with high reflectivity, is called "space." - Fuente: http://www.maxim-ic.com/appnotes.cfm/appnote_numbe r/2947 [maxim-ic.com]

Mmm... átomos líquidos. ¿Véis?: la electrónica introduciendo nuevos conceptos para el campo de la física. No es bonito verlos a todos colaborar?
