The latest roadmap to a 100 percent renewable energy future outlines infrastructure changes that 139 countries can make to be entirely powered by wind, water, and sunlight by 2050 after electrification of all energy sectors. Such a transition could mean less worldwide energy consumption due to the efficiency of clean, renewable electricity; and a net increase of over 24 million long-term jobs.

Surprise discovery in the search for energy efficient information storage

Added: 15.08.2017 13:14 | 0 views | 0 comments

#zrodlo

Today almost all information stored on hard disc drives or cloud servers is recorded in magnetic media, because it is non-volatile and cheap. For portable devices such as mobile phones and tablets, other forms of non-magnetic memory are used because the technology based on magnetism is impractical and is not energy efficient.

#zrodlo

Researchers have now reproducibly demonstrated current blockade -- the ability to switch a device from the insulating to the conducting state where charge is added and removed one electron at a time -- using atomically precise molecular clusters at room temperature. The study shows that single molecules can function as reproducible circuit elements such as transistors or diodes that can easily operate at room temperature.
