IBM Developing Transistor to Reduce 'Vampire Energy'

International Business Machines (IBM) is searching for a method that will cut devices%u2019 power consumption by 90% and reduce so-called vampire energy - power used by machines when they are turned off. IBM%u2019s Zurich lab is developing a transistor to regulate energy usage more efficiently, Bloomberg News said. The transistor would stop devices using energy while they are left plugged into an electrical outlet.
