New highly efficient thermoelectronic generator
Through a process known as thermionic conversion, heat energy—such as light from the sun or heat from burned fossil fuels—can be converted into electricity with very high efficiency. Because of its promise, ...
Capturing wasted electricity with triboelectric generators
(Phys.org) —With one stomp of his foot, Zhong Lin Wang illuminates a thousand LED bulbs – with no batteries or power cord. The current comes from essentially the same source as that tiny spark that jumps ...
Experiment opens the door to multi-party quantum communication (Update)
In the world of quantum science, Alice and Bob have been talking to one another for years. Charlie joined the conversation a few years ago, but now by enforcing the space-like separation of the three parties, ...
Researchers report on hardware Trojans that are undetectable
New device achieves self-biased solar hydrogen generation through microbial electrohydrogenesis at lab scale
A novel device that uses only sunlight and wastewater to produce hydrogen gas could provide a sustainable energy source while improving the efficiency of wastewater treatment.
The next big thing in the energy sector: Photovoltaic generated DC electricity
(Phys.org) —Energy consumption continues to grow. The costs of generation and transmission of energy must come down for the increased consumption to be sustainable. Energy must be generated without depleting ...
Bell Labs researchers build camera with no lens
People don't put a high value on climate protection
(Phys.org) —People are bad at getting a grip on collective risks. Climate change is a good example of this: the annual climate summits have so far not led to specific measures. The reason for this is that people attach ...
Harmonic holograms: High-speed three-dimensional imaging captures biological dynamics
CGI lighting, scanning deliver more realistic face (w/ Video)
Big beats bolster solar cell efficiency
(Phys.org) —Playing pop and rock music improves the performance of solar cells, according to new research from scientists at Queen Mary University of London and Imperial College London.
Green power blooms as Japan unveils 'hydrangea solar cell'
A solar cell that resembles a flower is offering a new take on green energy in Japan, where one scientist is searching for renewables that look good.
Scientists seek a newer, cheaper solar panel
Solar panels generate electricity by absorbing sunlight, but that is only half the battle. Once electrons in the panel are energized, they must be channeled in the same direction - a process that typically requires a panel ...
