Promises of a green racing revolution have yet to get off the grid, though. Last year, a fuel cell car was due to race in the prestigious Le Mans 24-hour race in France in June

greener and much quieter motor racing may be closer to the starting grid than you might think y

researcher Rabinowitch and colleagues have been pushing the idea of otato powerto deliver energy to people cut off from electricity grids.

or laptops in places where there is no grid, no power connection. Their cost analyses suggested that a single boiled potato battery with zinc

and copper electrodes generates portable energy at an estimated $9 per kilowatt hour, which is 50-fold cheaper than a typical 1. 5 volt AA alkaline cell or D cell battery,

which can cost $494 per kilowatt hour. It also an estimated six times cheaper than standard kerosene lamps used in the developing world.

But even with Google glass at the ready to tell us our favourite bar is a 400-calorie walk away,

The movement of the turbine blades creates, essentially, a phantom signal that even modern radars find hard to differentiate from a real moving aircraft.

The challenges of integrating wind and solar energy into the grid are cited often by the utility

Given its physical nature much of the wind-power attention of late has been on offshore turbines. Because the country like the U s. West Coast is on a continental shelf that drops off quickly in the sea this has required developing new floating turbine technology.

The bold technology integrates three turbines in a row or series and increases the electrical power output for a single tower.

and accelerates wind before delivering it to turbines safely and efficiently located at ground level. By placing three turbines in a series in an INVELOX system,

additional 120%power may be generated compared to a single turbine. Recent reports state technologies have allowed some markets in renewable generation to be competitive with coal or natural gas.

This is good news however, renewable energies intermittency and massive size challenges will continue without industry changes.

placing turbines safely covered at ground level allowing installation close to the end user. This could be the beginning of transforming wind power into the baseload power source that coal has been since the early 1900s.

Multiple turbines in a single INVELOX tower means nearly zero operational downtime because maintenance can be done on one turbine

while the others continue producing energy. With INVELOX capacity factor at 600%and turbines installed safely and conveniently at ground level,

maintenance costs and failure is reduced greatly. See video. Benefits of multiple turbines in single tower-120%additional power output at minimum added cost of turbine-generators-Reduced capital expenditure per kilowatt-Increased production capacity

-Gain in output without increasing footprint-Offers upgradability to meet increase in power demands-Minimizes operational downtime his is a great achievement,

for the first time in wind industry history three turbines may run in series in a single tower to produce more energy.

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,

The plasma protection is designed to increase the adhesion of the coating and therefore its resistance over time. fter a while

Plasma treatment is a versatile and powerful technique: by producing high frequency electric discharges, plasma generates'ionised'gas that can change the surface properties of the material it is in contact with.

In the study, the engineers demonstrate a 3-by-3 grid of compartments that allow magnetic beads to enter but not leave.

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

The new design is known as a spheromak meaning it generates the majority of magnetic fields by driving electrical currents into the plasma itself.

The researchers have tested successfully the prototype s ability to sustain a plasma efficiently and as they further develop

and expand the size of the device they can ramp up to higher-temperature plasma and get significant fusion power output.

The sun consists of hot plasma made of electrons and ions. Magnetic field lines extend from the solar surface all the way into the corona.

However calculations based solely on plasma turbulence were also unable to reproduce the occurrence of solar flares in full.

Using a supercomputer the team was able to show that the model consistently generated correct results even when changing details such as the number of flux tubes or the energy of the plasma.

The metallic nanostructures use surface plasmons waves of electrons that flow like a fluid across metal surfaces.

#Laser device sniffs out tiny traces of explosives University of California Berkeley rightoriginal Studyposted by Sarah Yang-Berkeley on July 24 2014mechanical engineers have found a way to dramatically increase the sensitivity of a light-based plasmon sensor.

The nanoscale plasmon sensor used in the lab experiments is much smaller than other explosive detectors on the market.

Because of this the researchers are hopeful that their plasmon laser sensor could detect pentaerythritol tetranitrate or PETN an explosive compound considered a favorite of terrorists.

The sensor represents the latest milestone in surface plasmon sensor technology which is used now in the medical field to detect biomarkers in the early stages of disease.

By coupling electromagnetic waves with surface plasmons the oscillating electrons found at the surface of metals researchers were able to squeeze light into nanosized spaces

The new device builds upon earlier work in plasmon lasers by Zhang s lab that compensated for this light leakage by using reflectors to bounce the surface plasmons back and forth inside the sensorâ##similar to the way sound waves

The amplified sensor creates a much stronger signal than the passive plasmon sensors currently available

and releasing electrical charge while subject to stresses or pressures up to 44 psi and vibrational accelerations over 80 g (significantly greater than those acting on turbine blades in a jet engine).

Nanostructured metamaterials however are making it possible to reduce the wavelength of light allowing the creation of new types of nanophotonic devices says Vladimir M. Shalaev scientific director of nanophotonics at Purdue s Birck Nanotechnology Center

Under development for about 15 years metamaterials owe their unusual potential to precision design on the scale of nanometers.

The key to the power harvester lies in its application of metamaterials engineered structures that can capture various forms of wave energy and tune them for useful applications.

Another application could be to improve the energy efficiency of appliances by wirelessly recovering power that is now lost during use. he properties of metamaterials allow for design flexibility not possible with ordinary devices like antennassays Katko. hen traditional antennas are close to each other in space they talk to each other

The design process used to create our metamaterial array takes these effects into account allowing the cells to work together. ith additional modifications the researchers say the power harvesting metamaterial could potentially be built into a cell phone allowing the phone to recharge wirelessly while not in use.

While the streetlights can run off-grid, groups of up to 99 of them are also able to send status updates via UHF to a central station,

As of mid-2014, more than 2, 000 megawatts of energy storage projects have applied to interconnect with the state s grid, according to recent data from state grid operator California ISO (PDF.

What s more, CAISO only tracks projects seeking interconnection to the high-voltage transmission grid, said Heather Sanders, the grid operator s director of smart grid technologies and strategy, at last week s Intersolar conference.

That leaves out all the distribution-grid-connected and customer-sited storage systems, which make up a combined 875 megawatts of the state s 1. 3-gigawatt target.

However, just because a storage project is in the queue doesn t mean it will be built, Sanders noted.
