“Superfast data processing using light pulses instead of electricity has been created by scientists.
The invention uses magnets to record computer data which consume virtually zero energy, solving the dilemma of how to create faster data processing speeds without the accompanying high energy costs.
Today’s data centre servers consume between 2 to 5% of global electricity consumption, producing heat which in turn requires more power to cool the servers.
Now an international team publishing in Nature has solved the problem by replacing electricity with extremely short pulses of light – the duration of one trillionth of a second – concentrated by special antennas on top of a magnet.
This new method is superfast but so energy efficient that the temperature of the magnet does not increase at all…”
