The timed light waves are delivered then to tiny array elements within a grid on the chip.
The light is projected then from each array in the grid, the individual array beams combining coherently in the air to form a single light beam and a spot on the screen. herefore, thanks to the complexity of the task at hand,
Similar to a coil or rail gun, a Gauss gun linearly accelerates an object using electromagnetic fields.
It can also be configured to store potential energy in the positions of objects inside its bore,
and then amplify the kinetic energy of an incoming particle by converting that potential energy into a larger kinetic energy added to an exiting object.

#irigamistretchable batteries could herald flexible electronics era Fitness trackers and smartwatches aren known for their battery life,
and it may have something to do with the inflexible, fixed-shape cell packs inside. A new experiment bears testimony to the idea that,
and flexible batteries should become more flexible, too. Arizona State university and China Jinan University have teamed up to create
what could become the first flexible batteries inside wearable electronics. The secret to these tretchable batteriesconsists of a traditional Japanese fold-and-cut practice of kirigami (which derives from origami.
and then replaced the 300mah battery inside Samsung Gear 2 smartwatch with the coated kirigami-cut aluminum foil.
To test out the new battery, the researchers connected the aluminum foil with two pliers, attached it to both the Gear 2 smartwatch
and stretched the lithium-ion battery to 150%of its original size. The result? The wearer bent
%the kirigami battery remained intact, and the Gear 2 smartwatch continued its video playback. ASU leader Dr. Jiang says that the kirigami-based design is the secret to the future of flexible electronics. he kirigami-based methodology can be expanded readily to other applications to develop highly stretchable devices
The goal behind stretchable batteries is to create mobile computing devices that are fully flexible devices that need not sacrifice elegance for functionality Flexible batteries will allow devices to become thinner, lighter,
and more formal while leaving room for two batteries to be placed inside a device instead of just one.
The Gear 2 300mah battery, as stated in the report, could become a 600mah battery that keeps a smartwatch

#Evaporation engines using artificial muscles made from bacteria A team of researchers from the US have created evaporation-driven engines that can power common tasks like locomotion and electricity generation.
These engines start and run autonomously when placed at airater interfaces. They are made from biologically inspired artificial muscles
Evaporation is a ubiquitous phenomenon in the natural environment and a dominant form of energy transfer in the Earth climate.
Engineered systems rarely use naturally occurring evaporation as a source of energy, despite a vast number of examples in the biological world.
yet the process carries a significant amount of energy. The breakthrough here is that near the evaporating surfaces,
in specially designed hydroscopic materials, it possible to convert energy from evaporation to mechanical work.
The engines are able to power an electricity generator to light up LEDS and drive a miniature car as the water evaporates please see the video on this page.

Its achievable bandgap also makes silicon highly absorptive to incoming energy sources like photons, and today most solar cells are based on silicon.
In theory, the success with simple transistors implies that this material could also help continue advances in solar cells.
What most exciting here after graphene has saturated headline space for so long, is that there was only a few months needed to take this purely theoretical 2d substance from a computer simulation to practical, working transistors.
#New material combines photons for big solar energy gains An innovative new approach to solar energy from University of California Riverside could dramatically increase the amount of light available to contemporary solar panel designs.
Rather than widening the absorption spectrum of the solar panels themselves, this new study looked at taking currently inaccessible infrared light and turning it into visible light.
They hope that by directing this newly fabricated light onto conventional solar panels, the efficiency of solar power could be improved greatly, for an affordable price.
Infrared light currently passes straight through most silicon solar cell technologies representing a substantial inefficiency in generating electricity from sunlight.
Much of solar research has worked to directly convert infrared light to electricity, but such technologies change the transistor design,
and thus the manufacturing process for solar panels. Their impacts tend to be limited by cost concerns, more than anything else.
These researchers chose to accept the absorptive abilities of current silicon transistors, and instead looked to make the light conform to the panels.
This photon has almost double the energy of the originals and more importantly, it exists in a form that existing solar panels can absorb.
By changing the incoming sunlight into silicon favorite for absorption, the material could improve solar panel efficiency by as much as 30%.
%And while the costs of the material itself are known not yet, there is huge potential in offering such large improvements without the need to completely reinvent the transistor manufacturing process.
but isn capable of directly passing it into the electricity generating process. Instead, the light moves on to the organic phase of the material,
The resulting, lower-wavelength photons can move on to be absorbed by the transistors of the solar panel as normal,
Infrared radiation accounts for an enormous amount of the energy in direct sunlight, and it is currently being missed by every solar panel outside of a research laboratory.
In general, this sort of research into the manipulation of light could allow a wider rollout of solar power around the world.
Plenty of raw energy is falling on highly clouded days, but the distribution of that energy through the spectrum is different,
and harder for modern solar panels to turn into power. Infrared radiation moves through and overcast sky quite well
however; if its energy could be added to that of the cloud-filtered visible light, solar might start to make good financial sense in less sunny areas than Texas and California.
The ability to accurately convert photons between wavelengths could have a wide range of applications, from medical imaging to optical data storage,

#New record efficiency for black silicon solar cells Researchers at the University of Aalto, Finland have broken the efficiency record for black silicon solar cells a type of cell that can gather sunlight even from tight
allowing solar cells that use it to trap light even when it's coming from very low angles.
This could be a good way to increase the yield of solar cells throughout the day
as they don't need the antireflection coatings used by many other types of solar cells. The main issue that has stifled the progress of black silicon cells is something known as carrier recombination.
When a photon hits a silicon atom inside a solar cell, the excess energy frees up an electron that is later used to generate electricity.

#Ricoh develops energy-generating rubber As digital technology becomes more ubiquitous and the Internet of things takes shape,
Japanese technology firm Ricoh is looking at its new"energy-generating rubber"as one solution.
According the company, the new piezoelectric polymer converts pressure and vibration into electric energy with high efficiency,
Piezoelectric materials come in two major forms; ceramics and polymers. Both are based on the principle of using mechanical strain to generate electricity
and are used in electronics to provide power in specialized applications, such as vibration and pressure sensors.
Ceramics convert vibration to energy with high efficiency, but theye heavy, fragile, and often include toxic lead,
According to Ricoh, its new energy-generating rubber combines flexibility and high energy output. It's not only less fragile than ceramics,
but it does say that it's engaged in further research to produce a commercially viable version of the polymer for both sensors and energy applications o
"Our molecular pump is radical chemistry an ingenious way of transferring energy from molecule to molecule,

"The fuel was created by Audi's project partner Global Bioenergies, in France. In late 2014, Global Bioenergies started up the fermentation unit for a pilot program to produce gaseous isobutane from renewable biomass sugars such as corn-derived glucose.
Gaseous isobutane is a sort of raw material for the petrochemical industry that can then be refined into a variety of plastics, fuels and other applications.
"says Global Bioenergies CEO Marc Delcourt.""It is the first time that we have produced real gasoline from plants."
"says Rick Bockrath, vice president for chemical engineering at Global Bioenergies.""It's basically how we're moving away from an oil-based economy towards something that has a renewable, sustainable future to it."

#New energy cell can store up solar energy for release at night A photoelectrochemical cell (PEC) is a special type of solar cell that gathers the Sun's energy
and transforms it into either electricity or chemical energy used to split water and produce hydrogen for use in fuel cells.
In an advance that could help this clean energy source play a stronger role within the smart grid, researchers at the University of Texas,
Arlington have found a way to store the electricity generated by a PEC cell for extended periods of time
and allow electricity to be delivered around the clock. Currently the electricity generated by a PEC cell could not be stored effectively,
as the electrons would quickly"disappear"into a lower energy state. This meant that these cells were not a viable solution for a clean energy grid,
as the electricity had to be used very shortly after being produced. That is, on sunny days, at a time when standard PV panels would already be producing energy at full tilt.
Now, researchers Fuqiang Liu and colleagues have created a PEC cell that includes a specially designed photoelectrode (the component that converts incoming photons into electrons.
Unlike previous designs, their hybrid tungsten trioxide/titanium dioxide (WO3/Tio2) photoelectrode can store electrons effectively for long periods of time,
paving the way for PEC cells to play a bigger role within a smart energy grid.
The system also includes a vanadium redox-flow battery (VRB. This is an already established type of energy storage cell that is very well-suited for the needs of the electrical grid as it can stay idle for very long times without losing charge,
is much safer than a lithium-ion cell (though less energy-dense), is nearly immune to temperature extremes,
and can be scaled up very easily, simply by increasing the size of its electrolyte tanks. According to the researchers, the vanadium flow battery works especially well with their hybrid electrode, allowing them to boost the electric current,
offering great reversibility (with 95 percent Faradaic efficiency) and allowing for high-capacity energy storage.""We have demonstrated simultaneously reversible storage of both solar energy
and electrons in the cell,"says lead author of the paper Dong Liu.""Release of the stored electrons under dark conditions continues solar energy storage,
thus allowing for continuous storage around the clock.""The team is now working on building a larger prototype,
with the hope that this technology could be used to better integrate photoelectrochemical cells within the smart grid.

#Smart low-carbon Solcer House generates more electricity that it uses A Welsh university claims to have built the UK first low-cost, low-carbon, energy-positive house.
and follows the"Buildings as Power stations"concept developed by the SPECIFIC Innovation and Knowledge Centre.
Energy-positive status is achieved by way of reduced energy demand, renewable energy supply and storing energy for later use.
Electricity is imported also from the grid when required and exported to the grid when there is a surplus.
Low-carbon cement was used for the construction of the Solcer House. To reduce its demand for energy
the house has high levels of thermal insulation, structural insulated panels (SIPS), external insulation and low-emissivity double-glazed aluminum-clad timber frame windows and doors.
Transpired solar collectors (TSC) are employed also. These comprise a perforated skin on the exterior of the house that draws air into the cavity
Electricity is generated by way of a 4. 3 kwp glazed photovoltaic solar panel array. This is fully integrated into the south-facing roof of the house
Energy that is not immediately required is stored in the house's 6. 9-kwh battery. Electricity generated and stored is used to power the heating, ventilation, hot water system and household appliances.
The Solcer House took 16 weeks to build and was completed in February this year. The video below shows the construction of the Solcer House e
