iPad App for Evaluating Household Appliances

Siemens has developed an app for the iPhone and iPad that calculates how much green household appliances can cut costs.

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.

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
