Everybody complains about high energy prices. And yet its so easy to save electricity – simply by switching off electrical appliances completely, rather than leaving them idling in standby mode. The Fraunhofer Institute for Systems and Innovation Research ISI has been investigating possible ways of raising consumers awareness of the energy they waste by leaving appliances switched on.
In a single year, the electrical equipment in German households and offices consumed an estimated 18 billion kilowatt-hours of power while switched to standby mode. That corresponds to almost the entire output of all the wind turbines producing electricity in Germany. Many consumer electronics devices take over 50 percent of their total power consumption in standby mode. “A set-top box for receiving digital TV, which will soon be an essential item in almost every household, consumes about eight watts in standby mode, day in, day out,“ remarks Barbara Schlomann of the ISI.
That doesnt sound much, but when you add it up over a whole year, it comes to somewhere around 54 kilowatt-hours. Multiply that by the approximately 60 million TVs in Germany, and you arrive at a figure of over three billion kilowatt-hours. Little is likely to change between 2004, the year that was studied, and 2015 with respect to the huge waste of power due to appliances running on standby.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
