Michigan Tech developing robot teams to restore power at disaster sites

By - September 29, 2014 2 Pictures
Thanks to mobile phone technology, getting caught in a disaster means that help is only a call away – unless the disaster knocks out the electricity to the cell towers. To help bring the phones back on line to aid in recovery efforts, researchers at Michigan Technological University are developing a team of robots designed to restore power to towers and other communication sites.

Long-lasting, water-based nuclear battery developed

By - September 17, 2014 1 Picture
Researchers working at the University of Missouri (MU) claim to have produced a prototype of a nuclear-powered, water-based battery that is said to be both longer lasting and more efficient than current battery technologies and may eventually be used as a dependable power supply in vehicles, spacecraft, and other applications where longevity, reliability, and efficiency are paramount.

Buddhist singing bowls could inspire highly efficient solar cells

By - September 14, 2014 1 Picture
While the unique shape of Buddhist singing bowls is vital to the creation of their signature sound, a researcher from Australia National University (ANU) has used their design as the inspiration for a new breed of solar cells. In completing his PhD at the University of Cambridge, Dr Niraj Lal found that just as the bowls cause sound to resonate, miniaturized versions can be made to interact with light in much the same way, inspiring solar cells better able to capture sunlight.

Buckyballs and diamondoids combined to create molecule-sized diode

By - September 10, 2014 3 Pictures
Scientists working at the Stanford Institute for Materials and Energy Sciences (SIMES) claim to have created a molecule-sized electronic component just a few nanometers long that conducts electricity in only the one direction. In essence, a rectifier diode, but one so small that it may one day help replace much bulkier diodes and other semiconductors found on today's integrated circuits to produce incredibly compact, super-fast electronic devices.

Air HES system to collect water and generate electricity from the clouds

By - August 27, 2014 7 Pictures
Using a tethered airship floating high up amongst the clouds, the Air HES concept claims to yield both clean water and electricity by harvesting and condensing water vapor which it uses to spin up an electric turbine generator to create power. According to the creators, they have built a prototype to test their theory and have also conducted feasibility studies into upping the scale of their device to produce economically viable levels of water and power.

3D-printed AirEnergy3D takes open source approach to wind turbines

By - August 18, 2014 10 Pictures
The AirEnergy3D is an open source, 3D-printed, portable wind turbine prototype whose creators claim will be able to generate up to 300 W of power. Designed to be easily assembled and disassembled without tools, the device is intended to be compact enough to be transported in a backpack, allowing it to be taken camping or anywhere else that there is a breeze and no access to the electricity grid.

Mobile phones could be charged using sound

By - August 12, 2014 1 Picture
Four years ago, we first heard about how Korean scientists had proposed using sound to charge mobile phones. They explained that it could be done via a piezoelectric effect, in which zinc oxide nanowires converted sound-caused vibrations into electricity. At the time, the researchers couldn't generate enough of a current to actually charge a phone. Now, however, scientists from Nokia and Queen Mary University of London (QMUL) have succeeded in doing so. Read More

oneTesla shrinks its singing Tesla coil kit to palm-friendly proportions

By - August 5, 2014 10 Pictures
The folks who successfully crowdfunded a DIY singing Tesla coil kit last year have taken to Kickstarter again to bring a smaller version into production. Like its older and bigger brother, the tinyTesla shoots out bolts of artificial lightning while playing MIDI music using the electricity itself. It looks like that polyphonic MIDI version of Danger High Voltage by Electric Six might just come in handy after all. Read More
