Solar-Power Device Would Use Heat to Enhance Efficiency

25/01/2014 16:49
 new approach to harvesting solar energy, developed by MIT researchers, could improve efficiency by using sunlight to heat a high-temperature material whose infrared radiation would then be collected by a conventional photovoltaic cell. This technique could also make it easier to store the...

E-Whiskers: Highly Sensitive Tactile Sensors Developed for Robotics and Other Applications

25/01/2014 16:47
From the world of nanotechnology we've gotten electronic skin, or e-skin, and electronic eye implants or e-eyes. Now we're on the verge of electronic whiskers. Researchers with Berkeley Lab and the University of California (UC) Berkeley have created tactile sensors from composite films of carbon...

Mechanical And Aerospace Engineers Use Satellites To Track Ozone Levels

25/01/2014 16:46
Engineers processed data from NASA's Aura satellite in order to track and predict the movement of airborne pollution. Using satellite data to measure ozone concentrations over time allows scientists and engineers to improve their models. This enables them to better their predictions and issue more...

Preventing Air Accidents: New Satellite-Based System

25/01/2014 16:43
A Norwegian, satellite-based system aims to ensure that helicopters and light aircraft are prevented from colliding with power lines and other obstacles. Collisions between light aircraft and helicopters and high voltage cables, wind turbines, high-rise buildings, oil platforms and telephony masts...

Material Developed Could Speed Up Underwater Communications by Orders of Magnitude

25/01/2014 16:40
University of California, San Diego electrical engineering professor Zhaowei Liu and colleagues have taken the first steps in a project to develop fast-blinking LED systems for underwater optical communications. Electrical engineers at UC San Diego have demonstrated that artificial materials can...

Manufacturing Glass Could Reduce Nuclear Waste By 90%

25/01/2014 16:23
Nuclear power is generally safer and may produce considerably less waste than forms of energy production from fossil fuels, but the waste it does make is extremely hazardous and needs to be handled very carefully. When not disposed of properly, it can cause a variety of cancers and has negative...

Mesmerizing video shows match burning in super slow motion

25/01/2014 16:21
It takes only an instant for a blow torch to light a match, but that doesn’t leave much time to actually appreciate the chemical reaction.   The slow-motion production company UltraSlo has released a new video showing what happens when you light a match. This time, the reaction is slowed...

Can Bees Be Trained to Sniff Out Cancer?

29/12/2013 13:49
December 13, 2013 Some insects, such as bees, have a sense of smell so acutely sensitive that they can locate the faintest of odors in a room, even if it consists of only a few molecules. But scientists are particularly intrigued by the fact that these bugs can even be...

Roboticists Create Rover To Move And Drill On The Moon

29/12/2013 13:46
 Engineers and robiticists created a robot to explore the moon. Running on the same amount of power as a 100-watt light bulb the rover uses heat from radiation to support its sensors, movement, and drill. It can move about five inches a second and work in harsh conditions to analyze the...

Producing Electricity On the Moon at Night

29/12/2013 13:43
Scientists from the Polytechnic University of Catalonia and other international collaborators have proposed a system of mirrors, processed lunar soil and a heat engine to provide energy to vehicles and crew during the lunar night. This would preclude the need for batteries and nuclear power sources...
