RE: [APML] Another nail in the coffin

These devices require extremely cold temperatures to operate.
Superconducting materials that work well for this application need
to be cooled below 1K.  The new high temperature superconductors
(>77K) don't seem to create nice junctions that can be used for
detection.  The requirement for extreme cryogenic temperatures might
keep this technology from ever becoming a consumer video product.

Another nail in the coffin of film astrophotography was announced
today.

Scientists at the European Space Agency have developed a new CCD
camera, called the S-Cam made of superconducting materials that are
so sensitive it can detect a single photon, as well as measure it's
position on the chip, it's color, and time of detection.
