#Implants And Powering Them From Within Your heart expends half a joule of energy every time it beats.

Before every contraction, the potential energy trapped in chemical bonds within cardiac muscle cells is released and converted into the mechanical power of the heartbeat.

But, like all energy, that which is harnessed to power the heart is destroyed never; it just changes form as it radiates away from the organ as heat and vibrations of surrounding tissue and fluid.

Now, a science team has announced a breakthrough in harvesting the energy released from the movement of the beating heart,

Theye developed a superthin device that can be attached to an organ to generate electricity from its movements.

The tiny device is already within the range of generating enough electricity to power a pacemaker on its own,

a coauthor of the study that was published on Jan 20 in the Proceedings of the National Academy of Sciences. he thing about cardiac pacemakers is that they are operated currently battery

a University of Illinois at Urbana-Champaign materials science and engineering professor. hen the battery runs out, you need to have surgery to replace it.

When the piezoelectric material flexes due to contraction and relaxation of the organ to which it is affixed,

it generates electrical energy from the movement. Because organ movements occur as pulses, the team had to include energy storage in their creation

so that electricity could be delivered continually. They accomplished this by building in a tiny chip-scale

commercially available battery into the device. Thin, flexible mechanical energy harvester, with rectifier and microbattery, mounted on the bovine heart.

or without batteries. ur ultimate goal is to replace the battery of an implant altogether,

ut even extending the life of the implant own battery is useful. They grew rat smooth muscle cells on their prototypes to determine that the materials were not toxic.

Their system converts mechanical to electrical energy at about two percent efficiency, a number that Rogers says is need based on the not to interfere with the target organ natural operation.

both inside and outside the human body. ardiac and lung motions, in particular, serve as inexhaustible sources of energy during the lifespan of a patient,

The potential to eliminate batteries or, at least, the need to replace them frequently represents a source of motivation for continued work in these and related directions. e

Like any electronic device, sensors need energy to operate. Until now this has largely been solved by hooking them up to the grid

or using batteries, but both approaches have considerable drawbacks. Grid-connected sensors need cables, limiting where they can be used,

and contribute to electricity consumption and CO2 EMISSIONS, while battery-powered ones only last as long as their battery life.

But what if sensors could harness energy directly from their environment from the sun, from ambient heat, from radio waves or vibrations?

The result would be sensors and sensor networks that can be set up anywhere with ease

What is needed are networks of devices that can survive by scavenging the energy they need from the environment."

and thermal energy as well as radio waves and vibrations to power themselves. They are focusing on making energy harvesters more efficient

The researchers are also developing intelligent algorithms (small programs) to efficiently manage the energy obtained from the environment.

in turn, reduces energy consumption. Apostolos Georgiadis, a senior research associate and the SWAP coordinator at CTTC in Spain, says the design of energetically self-sufficient networks differs sharply from that of standard battery-powered ones. he goal is no longer to minimise energy draw so as to maximise the lifetime of the battery reserve,

but rather to use energy when it is available and save it when we know it will be scarce,

so that the system will remain operational ideally forever, "he says. Combining the expertise of the academic and industrial partners,

and means small quantities can be chilled on demand, saving huge amounts of energy. Supermarkets, convenience stores, service stations, restaurants, hotels wherever you find people with money to spend,

Combined, commercial refrigerator/freezers like these are estimated to consume 85 TWH (terawatt hours) of electricity every year.

That is roughly equivalent to the total yearly output of eight or nine late-generation nuclear power plants. This places a huge burden on power grids and the environment

The technology developed delivers considerable energy savings while, at the same time, keeps up with growing consumer demand. Game-changing green technology like this could have a direct impact on the EU 2020 commitment to reducing energy use and greenhouse gas emissions while improving overall energy security,

the team suggests. EU Member States are preparing a combination of voluntary and mandatory initiatives to force a step change in energy consumption and the use of commercial refrigerated equipment.

Probably the most prominent of these is the Energy Using Products (EUP) Directive which is expected to enter into force in 2014.

Up to 90%energy saving Rapidcool developed an autonomous, modular-cooling apparatus for cooling drink cans and bottles from room temperature to around 4°C in some 50 seconds.

The project trademarked V-Tex technology recorded energy savings of 80-90%compared with open-front commercial refrigerators.

Their modular system is easy to clean (and thus to meet hygiene standards), simple to use,

#Promising technologies to reduce power plant emissions Carbon capture and storage (CCS) technology has the potential to help the European union (EU) significantly cut its greenhouse gas emissions.

However, efficient and reliable pre-combustion capture technologies that can reduce carbon dioxide (CO2 EMISSIONS from fossil fuel power plants at low cost are still missing.

The research team behind the EU-funded project DECARBIT developed new pre-combustion technologies that could lead to significant CO2 reductions from fossil-fuelled power plants by 2020

Post-combustion CO2 capture technology typically uses chemicals that extract CO2 from the exhaust gases in power plant (flue gases.

hese post-combustion processes are very energy intensive, mainly due to the energy required for regenerating the chemicals used in the capture operation,

explains project coordinator Marie Bysveen, Executive vice-president of SINTEF Energy Research in Norway. ew pre-combustion technologies,

on the other hand, remove the carbon from fuel before combustion and produce hydrogen, which is much more energy efficient,

sustainable sources of energy will remain a priority under Horizon 2020, the seven-year EU research and innovation programme launched on Jan 1, 2014.

In the call Competitive Low-Carbon Energy published on December 11 last year, the Commission proposed investing#732 million over two years in this area.

Applications for this kind of materials mix can be found in diverse domains such as the pharmaceutical industry, the food and processing industry, energy production or systems biology.

These results enable the operation to be estimated for a particular reactor and allow access to details that could not have been gained through measurements alone.

A detailed analysis of results enables engineers to improve reactor design for higher energy efficiency. Such reactors not only improve operating conditions

but also allow for a more sustainable use of resources. These outstanding results were possible thanks to a partnership between Prof.

Strategic partners from the academic and industrial sectors, namely FLSMIDTH (Germany), the Lithuanian Energy Institute (Lithuania) and Paul Wurth (Luxembourg), also made significant contributions thanks to their expertise

#This fusion reactor could be cheaper than coal University of Washington Posted by Michelle Ma-Washington on October 16 2014fusion energy almost sounds too good to be true#zero greenhouse gas emissions no long-lived radioactive waste a nearly unlimited fuel supply.

They have designed a concept for a fusion reactor that when scaled up to the size of a large electrical power plant would rival costs for a new coal fired plant with similar electrical output.

The team published its reactor design and cost-analysis findings last spring and will present results this week at the International atomic energy agency s Fusion energy Conference in St petersburg Russia. ight now this design has the greatest potential of producing economical fusion power of any current conceptsays Thomas Jarboe a professor

of aeronautics and astronautics and an adjunct professor in physics. The reactor called the dynomak started as a class project taught by Jarboe two years ago.

After the class ended Jarboe and doctoral student Derek Sutherland#who previously worked on a reactor design at the Massachusetts institute of technology#continued to develop

and refine the concept. The design builds on existing technology and creates a magnetic field within a closed space to hold plasma in place long enough for fusion to occur allowing the hot plasma to react and burn.

The reactor itself would be largely self-sustaining meaning it would continuously heat the plasma to maintain thermonuclear conditions.

Heat generated from the reactor would heat up a coolant that is used to spin a turbine

and generate electricity similar to how a typical power reactor works. his is a much more elegant solution because the medium in

which is crucial to keeping a fusion reactor going. The new design is known as a spheromak meaning it generates the majority of magnetic fields by driving electrical currents into the plasma itself.

and actually allows researchers to shrink the overall size of the reactor. Other designs such as the experimental fusion reactor project that s currently being built in France#called Iter#have to be much larger than the dynomak

because they rely on superconducting coils that circle around the outside of the device to provide a similar magnetic field.

When compared with the fusion reactor concept in France the dynomak is much less expensive#roughly one-tenth the cost of Iter

#while producing five times the amount of energy. Jarboe and colleagues factored the cost of building a fusion reactor power plant using their design

and compared that with building a coal power plant. They used a metric called vernight capital costswhich includes all costs particularly startup infrastructure fees.

A fusion power plant producing 1 gigawatt (1 billion watts) of power would cost $2. 7 billion

while a coal plant of the same output would cost $2. 8 billion according to their analysis. f we do invest in this type of fusion we could be rewarded

because the commercial reactor unit already looks economicalsutherland says. t s very exciting. ight now the concept is about one-tenth the size and power output of a final product

The team has filed patents on the reactor concept and plans to continue developing and scaling up its prototypes.

#New polymer makes solar cells more efficient Solar cells made from polymers have the potential to be cheap and lightweight

but scientists are struggling to make them generate electricity efficiently. A polymer is a type of large molecule that forms plastics

Now a team of researchers led by Yu has identified a new polymer that allows electrical charges to move more easily through the cell boosting electricity production. olymer solar cells have great potential to provide low-cost lightweight

The active regions of such solar cells are composed of a mixture of polymers that give and receive electrons to generate electrical current

The new polymer developed by Yu s group called PID2 improves the efficiency of electrical power generation by 15 percent

when added to a standard polymer-fullerene mixture. ullerene a small carbon molecule is one of the standard materials used in polymer solar cellslu says. asically in polymer solar cells we have a polymer as electron donor

and fullerene as electron acceptor to allow charge separation. n their work the researchers added another polymer into the device resulting in solar cells with two polymers and one fullerene.

when an optimal amount of PID2 was added the highest ever for solar cells made up of two types of polymers with fullerene

The group which includes researchers at the Argonne National Laboratory is now working to push efficiencies toward 10 percent a benchmark necessary for polymer solar cells to be viable for commercial application.

In order for a current to be generated by the solar cell electrons must be transferred from polymer to fullerene within the device.

But the difference between electron energy levels for the standard polymer-fullerene is large enough that electron transfer between them is difficult.

PID2 has energy levels in between the other two and acts as an intermediary in the process. t s like a stepyu says. hen it s too high it s hard to climb up

The fibers serve as a pathway to allow electrons to travel to the electrodes on the sides of the solar cell. t s like you re generating a street

#Sensor device grabs energy in odd places University of Washington Posted by Michelle Ma-Washington on September 4 2014scientists have built a new power harvester that uses natural fluctuations in temperature

The device harvests energy in any location where these temperature changes naturally occur powering sensors that can check for water leaks

Small cantilever motion harvesters are placed on the bellows and convert this kinetic energy into electrical energy. This powers sensors that also are placed on the bellows

A number of battery-free technologies exist that are powered by solar and ambient radio frequency waves.

A temperature change of only 0. 25 degrees Celsius creates enough energy to power the sensor node to read

#AAA BATTERY powers cheap water splitter A new device uses a regular AAA BATTERY to split water into hydrogen and oxygen.

The hydrogen gas could power fuel cells in zero emissions vehicles. The battery sends an electric current through two electrodes that split liquid water into hydrogen and oxygen gas.

Unlike other water splitters that use precious-metal catalysts the electrodes in the Stanford device are made of inexpensive and abundant nickel

Fuel cell technology is essentially water splitting in reverse. A fuel cell combines stored hydrogen gas with oxygen from the air to produce electricity

which powers the car. The only byproduct is water unlike gasoline combustion which emits carbon dioxide a greenhouse gas.

Most of these vehicles will run on fuel manufactured at large industrial plants that produce hydrogen by combining very hot steam and natural gas an energy-intensive process that releases carbon dioxide as a byproduct.

In 2015 American consumers will finally be able to purchase fuel cell cars from Toyota and other manufacturers.

could eventually save hydrogen producers billions of dollars in electricity costs according to Gong. His next goal is to improve the durability of the device. he electrodes are fairly stable

That goal is achievable based on my most recent resultshe researchers also plan to develop a water splitter than runs on electricity produced by solar energy. ydrogen is an ideal fuel for powering vehicles buildings

#New battery turns wasted heat into energy Stanford university rightoriginal Studyposted by Dan Stober-Stanford on May 22 2014researchers have developed a new battery technology that captures low-temperature waste heat

and converts it into electricity. Vast amounts of excess heat are generated by industrial processes and by electric power plants.

Researchers have spent decades seeking ways to harness some of this wasted energy. Most such efforts have focused on thermoelectric devicesâ##solid-state materials that can produce electricity from a temperature gradientâ

##but the efficiency of such devices is limited by the availability of materials. Now researchers have found a new alternative for low-temperature waste-heat conversion into electricityâ##that is in cases where temperature differences are less than 100 degrees Celsius.

The researchers describe the approach inâ Nature Communications. irtually all power plants and manufacturing processes like steelmaking

and refining release tremendous amounts of low-grade heat to ambient temperaturessays Yi Cui an associate professor of materials science and engineering at Stanford university. ur new battery technology is designed to take advantage of this temperature gradient at the industrial scale. he new system

is based on the principle known as the thermogalvanic effect which states that the voltage of a rechargeable battery is dependent on temperature. o harvest thermal energy we subject a battery to a four-step process:

heating up charging cooling down and dischargingsays Seok Woo Lee a postdoctoral scholar at Stanford

First an uncharged battery is heated by waste heat. Then while the battery is still warm a voltage is applied.

Once fully charged the battery is allowed to cool. Because of the thermogalvanic effect the voltage increases as the temperature decreases.

When the battery has cooled it actually delivers more electricity than was used to charge it. That extra energy doesn t appear from nowhere explains Cui.

It comes from the heat that was added to the system. The system aims at harvesting heat at temperatures below 100 C which accounts for a major part of potentially harvestable waste heat. ne-third of all energy consumption in the United states ends up as low-grade heatsays co-lead author Yuan

Yang a postdoc at the Massachusetts institute of technology (MIT. In the experiment a battery was heated to 60 C charged and cooled.

The process resulted in an electricity-conversion efficiency of 5. 7 percent almost double the efficiency of conventional thermoelectric devices.

This heating-charging-cooling approach was proposed first in the 1950s at temperatures of 500 C

or more says Yang who notesâ that most heat recovery systems work best with higher temperature differences. key advance is using material that was not around at that timefor the battery electrodes as well as advances in engineering the system says co-author Gang Chen a professor

of mechanical engineering at MIT. his technology has the additional advantage of using low-cost abundant materials

and manufacturing processes that are used already widely in the battery industryadds Lee. While the new system has a significant advantage in energy conversion efficiency over conventional thermoelectric devices it has a much lower power densityâ##that is the amount of power that can be delivered for a given weight.

The new technology also will require further research to assure long-term reliability and improve the speed of battery charging

and discharging Chen adds. t will require a lot of work to take the next step. here is currently no good technology that can make effective use of the relatively low-temperature differences this system can harness Chen says. his has an efficiency we think is quite attractive.

and deployed to use it. he results are very promising says Peidong Yang a professor of chemistry at the University of California Berkeley who was involved not in the study. y exploring the thermogalvanic effect the researchers were able to convert low-grade heat to electricity with decent efficiencyhe says. his is a clever idea

The DOE in part through the Solid-state Solar-Thermal energy Conversion Center helped support the MIT research.
