Mismatched alloys are a good match for thermoelectics
(PhysOrg.com) -- Using the supercomputers at NERSC, Berkeley Lab researchers demonstrated that the semiconductors known as highly mismatched alloys (HMAs) hold great promise for the future development of high ...
Offshore wind power and wave energy devices create artificial reefs
Offshore wind power and wave energy foundations can increase local abundances of fish and crabs. The reef-like constructions also favour for example blue mussels and barnacles. What's more, it is possible to increase or decrease ...
Scientists reveal Milky Way's magnetic attraction
(PhysOrg.com) -- An international research project involving the University of Adelaide has revealed that the magnetic field in the centre of the Milky Way is at least 10 times stronger than the rest of the ...
Researchers look at water-energy impacts of climate change
(PhysOrg.com) -- Climate projections for the next 50 to 100 years forecast increasingly frequent severe droughts and heat waves across the American Southwest, sinking available water levels even as rising mercury drives up ...
Galician waves are best for producing energy
The best coastal areas in the Iberian Peninsula in terms of harnessing wave energy are the Costa da Morte and Estaca de Bares, in La Coruña, Galicia, according to two pioneering studies by researchers from ...
On the Crest of Wave Energy
(PhysOrg.com) -- The ocean is a potentially vast source of electric power, yet as engineers test new technologies for capturing it, the devices are plagued by battering storms, limited efficiency, and the ...
Growth versus global warming
(PhysOrg.com) -- Houses on stilts, small scale energy generation and recycling our dishwater are just some of the measures that are being proposed to prepare our cities for the effects of global warming.
First light for BOSS -- a new kind of search for dark energy
BOSS, the Baryon Oscillation Spectroscopic Survey, is the most ambitious attempt yet to map the expansion history of the Universe using the technique known as baryon acoustic oscillation (BAO). A part of the ...
Could Exotic Matter Provide an Infinite Source of Energy?
A Theory of Dark Matter
Among the most astounding, unexpected, and important achievements of the past century (or even more) have been the discoveries of dark matter and dark energy, collectively dubbed the "dark sector."
Britain launches renewables drive to cut emissions
Britain announced plans Wednesday to slash emissions with a huge increase in the use of renewable energy to generate one third of the country's electricity needs by 2020.
Shaking the Fundamentals of Physics: At the Limits of the Photoelectric Effect
With extremely short wavelengths and very high intensities, light-matter interaction seems to be different than previously accepted.
Caribbean at risk of tsunami
Up to 30,000 residents and tourists could be under threat from a newly discovered tsunami risk in the Caribbean, according to experts in disaster risk management.
Implementing sustainable technology to monitor the integrity of the nation's bridges
Today, humans perform visual inspections every two years of most of the nation's older bridges. But with a scarcity of inspectors and tens of thousands of bridges, that process can be long and laborious.
