Called “energyRater” the new app can answer questions such as whether it would pay off to replace an Energy Efficiency Class B tumble dryer with a blueTherm heat pump dryer after five years, or how much money could be saved if the ten year-old refrigerator was disposed off and replaced with an A+++ appliance from Siemens.
To calculate the savings, users first have to select whether the appliance in question is a dryer, dishwasher, washing machine, refrigerator, or cooking range. They then select whether the device is new or old — either five or ten years old — or they enter some other data by hand. Further settings include the frequency with which the device is used in the household, the respective electricity and water fees, and the number of years the appliance is likely to be in use. Once this information has been entered, energyRater shows how much the savings will be. The results can be stored in order to calculate the total savings for several devices. Users can also e-mail the results.
Two particularly energy-efficient appliances are the blueTherm tumble dryer and the speedMatic dishwasher. In the case of the blueTherm, a comparison with a ten year-old device and a use of five times a week shows that electricity costs are cut by about €1,000 in total. The blueTherm features a unique automatic lint removal system and new heat pump technology. The dryer is therefore 40 percent better than the highest European Energy Efficiency Class A, and consumes only half as much electricity as conventional Energy Efficiency Class B appliances.
The Siemens speedMatic dishwasher has a special zeolitic drying system that makes it 20 percent more efficient than devices of the best Energy Efficiency Class A. The energyRater app calculates that a speedMatic that is used every day cuts electricity and water costs by a total of almost €600, compared to a ten year-old predecessor device.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
