Nanoparticle-based material turns up the heat on concentrated solar power

The key factor when it comes to solar power plant efficiency – be they of the photovoltaic or concentrated solar power variety – is the amount of light that can be captured by the light-absorbing material and converted into electricity or heat. Researchers at the University of California, San Diego have developed a new nanoparticle-based material that promises to improve the efficiency of CSP plants with its ability to absorb and convert over 90 percent of the sunlight it captures into heat.

Two-dimensional piezoelectric material forms basis of world's thinnest electric generator

Researchers from Columbia University and the Georgia Institute of Technology are laying claim to having observed piezoelectricity in an atomically thin material for the first time. The effect was demonstrated in the world's thinnest electric generator made from a two-dimensional molybdenum disulfide (MoS2) material, which had previously been predicted to exhibit such properties.Read More

Michigan Tech developing robot teams to restore power at disaster sites

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.Read More

Piezoelectric chin strap generates electricity from chewing

In a development that could bring new meaning to the term "motor mouth," Canadian researchers have developed a chin strap capable of generating electricity from jaw movements. The team is hopeful that the strap will be able to harvest energy from common actions like eating, chewing and talking to power medical implants and wearable devices. Read More

Long-lasting, water-based nuclear battery developed

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.Read More

Buddhist singing bowls could inspire highly efficient solar cells

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

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.Read More

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

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.Read More
