The latest and greatest materials in the field, nicknamed "high temperature superconductors", will only operate at temperatures below -140Â° Celsius. This may not seem warm to those of us who think of day-old pizza as "cold", but it's a huge improvement over the first generation of superconductors, which operate just a few degrees above absolute zero (-273Â° C).
implications for the environment are clear: superconductors are up to
100 times more compact than their regular counterparts, twice as
efficient, and lose no energy to heat dissipation. Imagine if the
world's computers all ran cold to the touch... no fans, no overheating,
and every chip overclocked to the theoretical limit!
Here's today's roundup of the latest news in the field:
- Superconductors unlock energy saving potential
- Tantalizing hint of room-temperature superconductor
- Supercondicting power lines to shore up New York electrical grid
- Breakthrough signals room temperature superconductor in ten years or less
- New type of superconductor emerges
