"Many researchers are looking to inorganic materials for new sources of energy, "said Elena Rozhkova, chemist at Argonne's Center for Nanoscale Materials, a DOE Office of Science (Office of Basic energy Sciences) User Facility."
"Our goal is to learn from the natural world and use its materials as building blocks for innovation."
"For Rozhkova, this particular building block is inspired by the function of an ancient protein known to turn light into energy.

#Stronger better solar cells: Graphene research on the cusp of new energy capabilities (Phys. org) There remains a lot to learn on the frontiers of solar power research particularly
when it comes to new advanced materials which could change how we harness energy. Under the guidance of Canada Research Chair in Materials science with Synchrotron radiation Dr. Alexander Moewes University of Saskatchewan researcher Adrian Hunt spent his Phd investigating graphene oxide a cutting-edge material that he hopes will shape the future
of technology. To understand graphene oxide it is best to start with pure graphene which is a single-layer sheet of carbon atoms in a honeycomb lattice that was made first in 2004 by Andre Geim
All of this makes graphene a great candidate for solar cells. In particular its transparency and conductivity mean that it solves two problems of solar cells:
first light needs a good conductor in order to get converted into usable energy; secondly the cell also has to be transparent for light to get through.
Most solar cells on the market use indium tin oxide with a nonconductive glass protective layer to meet their needs.
Indium is extremely rare so it is becoming more expensive all the time. It's the factor that will keep solar cells expensive in the future
whereas graphene could be very cheap. Carbon is said abundant Hunt. Although graphene is a great conductor it is not very good at collecting the electrical current produced inside the solar cell
which is why researchers like Hunt are investigating ways to modify graphene to make it more useful.
Whether or not it will solve the solar panel problem is yet to be seen and researchers in the field are building up their understanding of how the new material works.
It's a pitfall that could be important to understand in the development of long-lasting solar cells where sun could provide risky heat into the equation.
More research like this will be the key to harnessing graphene for solar power as Hunt explains.
"One application the group is now exploring is a thin film solar cell, made of densely packed nanowires,
that could harvest energy from light much more efficiently than traditional thin-film solar cells s
#Device Could Harvest Wasted Energy From Wi-fi, Satellite Signals A wireless device developed by researchers at Duke university that converts microwaves into electricity could eventually harvest Wi-fi or satellite signals for power according to its creators.

#U k. Supermarket To Run on Electricity Made From Its Own Rotting Food One U k. grocery store plans to power itself using biogas harvested from its own unsold, rotting produce.
The store plans to use electricity solely from the digesters, taking no electricity from the U k.'s national power grid,
which is fed by a combination of coal, natural gas, nuclear power plants and other sources. Sainsbury's will even sell any excess electricity it makes back to the grid.
The Cannock Sainsbury's will be the first U k. store to stop using U k. grid electricity
the BBC reports. While we've never heard of a big U s. store doing exactly that,
U s. grocery-store chain Kroger is supposed to have an anaerobic digester that provides more than 20 percent of the electricity needs of its Compton distribution center.

They designed a pixel that can not only measure incident light but also convert the incident light into electric power.
although digital cameras and solar panels have different purposes-one measures light while the other converts light to power-both are constructed from essentially the same components.
The same photodiode is used also in solar panels to convert incident light to electric power. The photodiode in a camera pixel is used in the photoconductive mode
while in a solar cell it is used in the photovoltaic model. Nayar, working with research engineer Daniel Sims BS'14 and consultant Mikhail Fridberg of ADSP Consulting, used off-the-shelf components to fabricate an image sensor with 30x40 pixels.
and then to harvest energy and charge the sensor's power supplyhe image sensor continuously toggles between image capture and power harvesting modes.
When the camera is used not to capture images, it can be used to generate power for other devices,
Nayar notes that the image sensor could use a rechargeable battery and charge it via its harvesting capability:"
and used just a capacitor to store the harvested energy.""""A few different designs for image sensors that can harvest energy have been proposed in the past.

000 suns The latest in solar power comes to us from Swiss inventors working for Airlight Energy, Dsolar (a subsidiary of Airlight),
It uses something called HCPVT (Highly Efficient Concentrated Photovoltaic/Thermal) to generate electricity and hot water from solar power.
as well as highly efficient photovoltaic cells (known as gallium arsenide photovoltaic cells) to convert that concentrated solar energy into electricity. Though concentrated solar thermal power
and PVS are nothing new to the solar power industry, the Solar Sunflower incorporates these technologies in a novel way that represents a few ingenious engineering breakthroughs.
"In other words, the difference between this technology being classified as a death ray as opposed to a solar array is merely a matter of how the reflectors are angled.
Photovoltaic cells used by the Sunflower have a max operating temperature of around 105 degrees Celsius,
The end result is a device that produces about 12kw of electricity, along with 21kw of thermal energy.
Even though that doesn't amount to a huge amount of energy (the 12kw of electricity is only enough to power a few homes, for instance),
it is nonetheless highly efficient. The real obstacle to the implementation of the Solar Sunflower is its cost.
Its gallium arsenide photovoltaic cells though more efficient than standard PV cells, are not cheap. Add up construction costs and the costs of the fancy cooling system,
and the design isn't going to be able to financially compete with less innovative but sure-fire solar energy harvesters already on the market.
This research outcome potentially allows for great flexibility in the design and optimization of electronic and optoelectronic devices like solar panels and telecommunication lasers.
All these properties combined make it a tremendous conductor of heat and electricity. A defectree layer is also impermeable to all atoms and molecules.

And then, with this enhanced view,"this energy barrier can be eliminated entirely, "the team writes.
the new research provides a powerful way to explore many other types of organic materials, too--with particular promise for improved solar cells.

which the absorbed energy (exciton) migrates through the system prior to splitting into charges that are converted to electricity."
--and can't be pushed by voltage like the electrons flowing in a light bulb--they can, in a sense, bounce from one of these tightly stacked molecules to the next.
This allows organic thin films to carry energy along this molecular highway with relative ease,

requires a significant amount of energy. Reverse osmosis, a more energy-efficient process that nonetheless requires a fair amount of energy,
is the basis for the ORNL technology. Making pores in the graphene is key. Without these holes, water cannot travel from one side of the membrane to the other.
"That all serves to reduce the amount of energy that it takes to drive the process."
Then the team exposed the graphene to an oxygen plasma that knocked carbon atoms out of the graphene's nanoscale chicken wire lattice to create pores.
The longer the graphene membrane was exposed to the plasma, the bigger the pores that formed,

#Harvesting energy from electromagnetic waves (Nanowerk News) For our modern, technologically-advanced society, in which technology has become the solution to a myriad of challenges,
energy is critical not only for growth but also, more importantly, survival. The sun is an abundant and practically infinite source of energy,
so researchers around the world are racing to create novel approaches to"harvest"clean energy from the sun or transfer that energy to other sources.
This week in the journal Applied Physics Letters("Metamaterial electromagnetic energy harvester with near unity efficiency"),researchers from the University of Waterloo in Canada report a novel design for electromagnetic energy harvesting based on
the"full absorption concept.""This involves the use of metamaterials that can be tailored to produce media that neither reflects nor transmits any power--enabling full absorption of incident waves at a specific range of frequencies and polarizations."
"The growing demand for electrical energy around the globe is the main factor driving our research,
"said Thamer Almoneef, a Ph d. student.""More than 80 percent of our energy today comes from burning fossil fuels,
which is both harmful to our environment and unsustainable as well. In our group, we're trying to help solve the energy crisis by improving the efficiency of electromagnetic energy-harvesting systems."
"Since the inception of collecting and harvesting electromagnetic energy, classical dipole patch antennas have been used.""Now, our technology introduces'metasurfaces'that are much better energy collectors than classical antennas,
"explained Omar M. Ramahi, professor of electrical and computer engineering. Metasurfaces are formed by etching the surface of a material with an elegant pattern of periodic shapes.
The particular dimensions of these patterns and their proximity to each other can be tuned to provide"near-unity"energy absorption.
This energy is channeled then to a load through a conducting path that connects the metasurface to a ground plane.
The key significance of the researchers'work is that it demonstrates for the first time that it's possible to collect essentially all of the electromagnetic energy that falls onto a surface."
"Conventional antennas can channel electromagnetic energy to a load --but at much lower energy absorption efficiency levels,"said Ramahi."
"We can also channel the absorbed energy into a load, rather than having the energy dissipate in the material as was done in previous works."
"As you can imagine, this work has a broad range of applications. Among the most important is space solar power,
an emerging critical technology that can significantly help to address energy shortages. It converts solar rays into microwaves--using conventional photovoltaic solar panels--and then beams the microwave's energy to microwave collector farms at designated locations On earth.
Japan is way out in front of rest of the world in this realm, with plans to begin harvesting solar power from space by 2030."
"Our research enables significantly higher energy absorption than classical antennas, "Ramahi said.""This results in a significant reduction of the energy harvesting surface footprint.
Real estate is a precious commodity for energy absorption --whether it's wind, hydro, solar or electromagnetic energy."
"Other key applications include"wireless power transfer--directly adaptable to power remote devices such as RFID devices and tags or even remote devices in general,"Ramahi noted.
The technology can also be extended to the infrared and visible spectra.""We've already extended our work into the infrared frequency regime
and we hope to report very soon about near-unity absorption in those higher-frequency regimes,"added Ramahi i
