#Silly Putty material inspires better batteries Using a material found in Silly Putty and surgical tubing, a group of researchers at the University of California,
Riverside Bourns College of Engineering have developed a new way to make lithium-ion batteries that will last three times longer between charges compared to the current industry standard.
The team created silicon dioxide (Sio2) nanotube anodes for lithium-ion batteries and found they had over three times as much energy storage capacity as the carbon-based anodes currently being used.
which are always trying to squeeze longer discharges out of batteries.""We are taking the same material used in kids'toys
and medical devices and even fast food and using it to create next generation battery materials, "said Zachary Favors,
The paper,"Stable Cycling of Sio2 Nanotubes as High-performance Anodes for Lithium-Ion Batteries,"was published online in the journal Nature Scientific Reports.
Silicon dioxide has previously been used as an anode material in lithium ion batteries, but the ability to synthesize the material into highly uniform exotic nanostructures with high energy density
There key finding was that the silicon dioxide nanotubes are extremely stable in batteries, which is important

#Flexible supercapacitor raises bar for volumetric energy density Scientists have taken a large step toward making a fiber-like energy storage device that can be woven into clothing
The device is a supercapacitor cousin to the battery. This one packs an interconnected network of graphene and carbon nanotubes so tightly that it stores energy comparable to some thin-film lithium batteriesn area where batteries have held traditionally a large advantage.
The product's developers engineers and scientists at Nanyang Technological University (NTU) in Singapore Tsinghua University in China and Case Western Reserve University in the United states believe the storage capacity by volume
(called volumetric energy density) is reported the highest for carbon-based microscale supercapacitors to date: 6. 3 microwatt hours per cubic millimeter.
The device also maintains the advantage of charging and releasing energy much faster than a battery.
and serve as energy-carrying wires in medical implants. Yuan Chen a professor of chemical engineering at NTU led the new study working with Dingshan Yu Kunli Goh Hong Wang Li Wei and Wenchao Jiang at NTU;
Conversely batteries have high energy density and low power density which means they can last a long time
but don't deliver a large amount of energy quickly. Microelectronics to electric vehicles can benefit from energy storage devices that offer high power and high energy density.
That's why researchers are working to develop a device that offers both. To continue to miniaturize electronics industry needs tiny energy storage devices with large volumetric energy densities.
By mass supercapacitors might have comparable energy storage or energy density to batteries. But because they require large amounts of accessible surface area to store energy they have lagged always badly in energy density by volume.
To improve the energy density by volume the researchers designed a hybrid fiber. A solution containing acid-oxidized single-wall nanotubes graphene oxide and ethylenediamine
which promotes synthesis and dopes graphene with nitrogen is pumped through a flexible narrow reinforced tube called a capillary column and heated in an oven for six hours.
Sheets of graphene one to a few atoms thick and aligned single-walled carbon nanotubes self-assemble into an interconnected prorous network that run the length of the fiber.
and remain so as they're pumped out resulting in the high volumetric energy density. The process using multiple capillary columns will enable the engineers to make fibers continuously
When they integrate multiple pairs of fibers between two electrodes the ability to store electricity called capacitance increased linearly according to the number of fibers used.
Using a polyvinyl alcohol/phosphoric acid gel as an electrolyte a solid-state micro-supercapacitor made from a pair of fibers offered a volumetric density of 6. 3 microwatt hours per cubic millimeter
which is comparable to that of a 4-volt-500-microampere-hour thin film lithium battery. The fiber supercapacitor demonstrated ultrahigh energy density value
while maintaining the high power density and cycle stability. We have tested the fiber device for 10000 charge/discharge cycles
while conventional rechargeable batteries have a lifetime of less than 1000 cycles. The team also tested the device for flexible energy storage.
Woven into uniforms the battery-like supercapacitors could power displays or transistors used for communication.
In addition The team is interested also in testing these fibers for multifunctional applications including batteries solar cells biofuel cells
You could print a MASSIVE heat exchanger to reclaim heat from waste water power plants your house...You like fresh air
the Fukushima nuclear power plant. Since then multiple earthquakes have struck this region including a M7. 3 quake in December of last year
As the scorching-hot air moves through the exchanger the chilled tubing absorbs the energy cooling the air to minus 238 degrees Fahrenheit in a fraction of a second.
If it were in a power station it would probably be a 200-ton heat exchanger he says.
They get more energy out of the liquid hydrogen than you can get just burning it.
so using much of the energy that went into making it a liquid is very effective.
The intent is to save energy by controlling the temperature of an individual person rather than an entire building a goal that anyone who's ever turned on a personal space heater in a frigid office building in July can get behind.
So researchers sent down pulses of radio energy of this particular frequency. By analysing this radar data the team were able to map the topography of the underlying bedrock.
The light enters the water it hands off part of its energy to the medium and inside it exists as light
and a lot more energy is given away than during refraction. The result of that process? As the photons exited the cloud they were clumped together.
#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.
It could also one day be built into cell phones to let them charge while not in use they say.
In this case the microwave-harvesting metamaterial that acts kind of like a solar panel converting microwaves into up to 7. 3 volts of electricity enough to charge small electronics.
and make lost energy usable. â##It s possible to use this design for a lot of different frequencies
and types of energy including vibration and sound energy harvestingâ#according to Duke graduate student Alexander Katko one of the inventors. â##Until now a lot of work with metamaterials has been theoretical.

#Planet Without A Star Found â##We have seen never before an object free-floating in space that that looks like this.
The habitable zone includes orbits where planets receive the same amount of stellar energy from a star as the Earth receives from the sun. Earth-size planets include those that are between one and two times the size of Earth.
State-run news agency Ria Novosti has said that it will carry dust monitors and plasma sensors to sense high-energy cosmic rays as well.
Kacyra's company built a scanner that could work outside off battery power and didn't require special protective shielding for eyes.
The blade tips of today's tallest conventional wind turbine installed at a test center in Denmark this year stretch to 720 feet.
One contains copper conductors that transmit power collected as high as 2000 feet down to a battery or the grid.
There is more than enough energy in high-altitude winds to power all of civilization says Ken Caldeira a Stanford university climate scientist who co-authored a 2012 study that ballparked the potential at 1800 terawatts--more than four times the estimate near the surface.
Altaeros Energies the company behind that BAT is poised to prove that it's already done so.
Often they must rely on diesel generators--one of the least-efficient power sources --because renewable energy systems are not economically feasible.
and so the Alaska Energy Authority awarded Altaeros a $740000 grant to demonstrate its technology. The company plans to start flying its first commercial-scale BAT a 30-kilowatt system that could reduce diesel consumption by 11000 gallons annually near Fairbanks next year.
A megawatt-class BAT anchored 10 miles off the coast would need significantly smaller foundations than traditional offshore wind systems
From the sci-tech perspective important energy and conservation agreements were announced. Now the hard work of putting them into action begins for the pledgers and signers as well as those watchdogging that process.

#An All-Liquid Battery For Storing Solar And Wind energy You could call it a rainy-day fund.
A team of MIT researchers has built an all-liquid battery prototype that's designed to store excess energy from solar and wind power plants.
or the wind isn't blowing future versions of this battery could release energy captured during more productive times into nations'power grids.
Cheaper more efficient energy storage would be a big boost for alternative energy technologies. It would help solar panels
and wind turbines provide grids with steady electricity instead of surges during sunny or windy times so it's always there in case of high demand.
It also might make sun-and wind-produced electricity cheaper; by storing extra energy that isn't being used less electricity is wasted in the long run.
There are already solid batteries sold now to store energy from solar panels. They're mostly used in single homes however.
As solar facilities get larger solid batteries get more expensive and less efficient compared to how much energy the whole facility makes.
The MIT team thinks an all-liquid battery filled with searingly hot molten metals might be a good alternative.
Liquid batteries may be easier (and thus cheaper) to manufacture in larger sizes and they're expected to last longer than solid ones.
The team previously made a prototype all-liquid battery filled with magnesium and an element called antimony.
With this latest version the team has made a battery with lithium and antimony mixed with lead.
It has compared some advantages to its predecessor. Mixing the antimony with lead makes the materials cheaper.
Plus the battery can be kept at lower temperatures. It works at 450 degrees Celsius versus 700 degrees Celsius.
The team even conducted a durability test charging and discharging the liquid battery for 1800 hours.
From that data it predicts that the battery would lose 15 percent of its capacity after 10 years of daily use.
Engineers have known long about how important storage is to solar and wind energy given their unreliable natures.
For example evenings can be a high-demand time for electricity but they're not particularly sunny.
Additionally there can be an overproduction of solar energy during daylight hours meaning valuable electricity goes to waste frequently.
Research groups are working on a number of storage schemes to fix these issues from flywheels to liquid nitrogen and oxygen.
though energy use payload capacity and speed counted as well. The question to answer according to Jordy de Renet one of Stella s drivers was Do you want it in your daily life?
It also allowed for more surface area for solar cells which cover 6 square meters. The 60-kw battery sheathed in a bright yellow casing runs down the center of the vehicle
and provides up to about 400 km of range or 800 km when the solar panel is providing maximum juice.
On Stella s best day during the competition Solar Team Eindhoven was able to drive 500 km at an average of 100 km/hr.
The solar array charges while the car is in motion as well as when it is parked. We get more energy out of the car than is needed to drive it said de Renet.
That power as much as twice what the car uses can be returned to the grid. The system uses a Wi-fi protocol for vehicles 802. 11p to see where the driver cannot.
Motors batteries sensors and electronic control systems located at the ends of the rods can loosen or tighten the tension of the cables.
#Turning Old Lead Batteries Into New Solar energy Used car batteries can leech chemicals and create lead pollution
--and put to good use creating emissions-free energy. In newly published research the scientists show that recycled lead from car batteries works as well as fresh lead
when used in solar cells made with organolead halide perovskite film a compound that is fast becoming competitive with silicon in solar power technology.
Quoting MIT energy professor Angela Belcher a study co-author an MIT press release notes that with time ticking down on lead-acid batteries in favor of lithium ion cells we need to be thinking ahead on handling a looming toxic waste problem:
Perovskite solar panels are also less energy-intensive to build compared to silicon-based cells and the leaded film would be contained completely within other materials.
The research Environmentally-responsible fabrication of efficient perovskite solar cells from recycled car batteries was published recently online by the journal Energy and Environmental science.

Much of the world's energy actually comes from steam-coal power plants heat up water to produce water vapor,
which turns turbines to generate electricity. A new technology creates steam by harnessing solar energy, using a relatively cheap sponge-like material,
The researchers don't claim the device could be used to create electricity, at least not yet. But it could relatively easily be scaled up to make fresh water out of salt water via distillation
or food processing equipment in areas of the world where electricity is hard to come by, said MIT researcher Hadi Ghasemi in a statement.
#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.

Theyâ##re already delivering amazing products you can buy right nowâ##thermostats that save energy
and walk across our desk using off-the-shelf motors batteries and electronic components? There are multiple ways to keep a cube in its balance
but jumping up requires a sudden release of energy. Intuitively momentum wheels seemed like a good idea to store enough energy while still keeping the cube compact and self-contained.
Furthermore the same momentum wheels can be used to implement a reaction-torque based control algorithm for balancing by exploiting the reaction torques on the cube body
(i e. more energy for jump up) and higher torques (i e. better stability when balancing). This mathematics-driven hardware design resulted in detailed specs for the robot core hardware components (momentum wheels motors gears
and batteries) and allowed a CAD design of the entire system. Part of this step was the design of a special brake to suddenly stop a momentum wheel to transfer its energy to the entire cube
and cause it to jump up. The photo to the left shows an early design of this brake consisting of a screw mounted on the momentum wheel a servo motor (shown in black) to move a metal plate (in blue) into the screw path (in light brown)
and a mounting bracket (in light brown) to transfer the momentum wheel energy to the cube structure.
if the timing is correct the braking energy of one axis can be used as energy for another in the same way as a regenerative braking system reducing energy usage. his system is used currently in the automotive chip-making printing and food industries.
The Ship Inspection Robot (SIR) which was developed in conjunction with Alstom Inspection Robotics and which uses magnetic wheels to navigate the I-beams
The projectsir was developed as part of an industrial-academic collaboration between Alstom Inspection Robotics ETH Zurich and ZHDK.
Alstom Inspection Robotics proposed a project that would result in a lightweight low-cost robot for inspecting ships
and allowed us to develop together with Alstom Inspection Robotics a realistic potential inspection scenario that would serve as a guide for SI#eventual design.
Calculations done on power consumption suggest a run time of about three hours; with an assumed average speed of 4. 5 cm/s (calculated as a weighted mix of maximum
and obstacle speed) ten of these sections could be inspected on a single battery charge. Once inspection is complete the data is analysed
and a powerful battery allows for approximately three hours of run time on a single charge.
The ability to climb all these additional obstacles is not only beneficial for ship inspection but also useful for many other robot applications such as power plant inspections.
Further development of SIR lies in Alstom Inspection Roboticsâ#hands
