Future Computers that are “Normally Off”

Spintronics-Based Technology May Replace Volatile Memory And Enable Extremely Energy-Efficient, Hand-Cranked Or Solar-Powered Devices
If a research team in Japan gets its wish, “normally off” computers may one day soon be replacing present computers in a move that would both eliminate volatile memory, which requires power to maintain stored data, and reduce the gigantic energy losses associated with it.

Most parts of present computers are made with volatile devices such as transistors and
