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,

which very efficiently absorbs the light energy and turns it to heat. This layer is bonded tightly to a layer of a photonic crystal,
ensuring that most of the energy collected by the absorber is turned then into electricity. Now, the MIT device is only at about 3. 2 percent efficiency a big jump over the less than 1 percent STPV devices that have been seen before

however, renewable energies intermittency and massive size challenges will continue without industry changes. Sheerwind INVELOX attends to the intermittency
and size issues by combining the best traditional wind technologies with a unique wind delivery system that produces more efficient and powerful wind generation machines.
Ultimately combining technologies will allow us to achieve the necessary power generation capacities to transform wind energy into a reliable baseload power source.
This could be the beginning of transforming wind power into the baseload power source that coal has been since the early 1900s.
for the first time in wind industry history three turbines may run in series in a single tower to produce more energy.
Its patented INVELOX wind funnel technology brings wind energy production to ground level. By capturing, concentrating, and accelerating wind energy, ultimately reducing costs,
while solving major problems that have plagued the industry, including low turbine reliability, intermittency issues, and environmental impacts.
Sheerwind is poised to turn wind power into a major power source for the globe. For more see:

which would enhance the manufacturing of solar energy panels, making them more efficient and less expensive than anything currently available.
but also delivering environmental benefits through the development of improved methods for harnessing solar energy. urope is a global powerhouse
Solar panels are able to function because they have intricate patterns of tiny channels engraved into their surface,
high-tech materials now being developed for solar panels. In place of conventional solar panels measuring up to 5 millimetres in thickness,
the modern PV industry is looking to use new types of lightweight and flexible materials to construct solar panels measured in micrometres (thousandths of a millimetre).
With such materials, the scribing process must be controlled with a high degree of accuracy since it is vital that it penetrates only one layer of the thin solar cell film at a time.
PCF lasers provide this accuracy. Moreover, since PCF lasers operate with ultra-short pulse rates,
the flexibility means that solar panels can be wrapped onto any suitable structure, flat or curved. The results of the ALPINE team work, demonstrating the capability of PCF lasers to transform existing scribing technology and opening the way to rapid growth in the high-volume production of flexible,
thin-film solar cells, are hard to overestimate. In the words of Professor Selleri: echanical scribing will disappear very quickly from the PV industry,
and enhance the efficient use of resources like water electricity and raw materials. Gearing up for the future Through a number of case studies the team addressed specific problems affecting the milling grinding and drilling of different metals.
Applications abound Another application for MUPROD work is the manufacturing of large but lightweight parts for wind power.
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

#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
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.
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

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.
