Nano Particles in the Storage of Hydrogen Fuel and Electricity Production-Crazy technology world
Hydrogen is the most promising form of energy storage.It can be used to produce electricity directly in a hydrogen fuel cell and can also be burnt like any other fuel thus an alternative of fossil fuels.Fuel cells which run on other fuels like methanol, natural gas etc, they run less cleanly than on hydrogen, and require
higher operating temperatures,more expensive materials, and more careful design to avoid fouling and achieve good long-term performance.

What are the Issues that prevent Hydrogen Use Uptill Now?
The problems with adoption of hydrogen thus far have resulted from the production and storage of hydrogen gas. Existing processes for producing hydrogen require a large amount of energy which typically comes from fossil fuels, negating the environmental benefits of the otherwise carbon-free and pollution-free fuel.
Storage of hydrogen is also an issue, as it is highly flammable in its free gaseous form. Storing and transporting the fuel safely is therefore a priority. Much research effort has gone into developing a viable commercial solution to these problems.
Role of Nano Particles in hydrogen Production
Photocatalytic nano particles have the ability to use the energy from sunlight to decompose molecules. So far, this has mostly been applied to self-cleaning surfaces, but a good deal of research has gone into investigating and optimizing the photocatalytic properties of various nanomaterials for splitting water into hydrogen and oxygen.
Titanium Dioxide nanotubes can convert water into hydrogen and oxygen using the power of sunlight. Further research will try to optimize the technology so it can compete with established natural gas-based routes for manufacturing hydrogen
Nano Particles in storing hydrogen
Locking hydrogen into solid materials has long been seen as the way forward. Hydride-forming materials can absorb hydrogen and store it securely at much higher densities than are available by other means. However, conventional materials cannot store very large amounts of hydrogen, and require extremes of temperature to make the capture and release of hydrogen efficient enough for commercial applications.
Nanostructured materials have unique and tunable properties which are much more suited to this application. Researchers around the globe have found nanomaterials which are capable of storing hydrogen at high densities. The key is to find a material which has controllable hydrogen affinity, and can absorb and release its full capacity of fuel in the shortest time possible.
Nanotechnology has the key to viable solutions to the two major problems holding back the hydrogen economy:
- production of hydrogen using renewable energy sources,
- and safe storage and distribution of hydrogen around the world.
Photocatalytic production of hydrogen from water and storage of hydrogen using novel nanomaterials could form the basis of a viable distribution infrastructure, effectively allowing vehicles and local combined heat and power (CHP) systems to run on solar energy, stored as clean and efficient hydrogen fuel.

Introduction to Alternative Energy
Alternative Energy is an energy supply that is alternate to the conventional Fossil Fuels.These alternatives are meant to address worries about such fossil fuels.
HZY
Alternative energy refers to energy sources that don't have any unsought consequences such as in case of fossil fuels. Energy sources that are renewable are thought to be "free" energy sources. all of them have lower carbon emissions, compared to traditional energy sources. These embody Biomass Energy, Wind Energy, alternative energy, heat, electricity Energy sources. Combined with the utilization of employment, the utilization of different energies like the house use of alternative energy systems can guarantee man's survival into the twenty first century and on the far side
Why there is a need of conventional fossil fuel alternatives?
Our planet produces greenhouse emission (Carbon dioxide) that's discharged to the earth’s atmosphere and which can still be there in 100 years time.This inflated content of greenhouse emission will increase the heat of our planet and is that the main reason for “Global Warming Effect”.The need of the hour is to move towards the alternative energy sources which should be cheap and of higher performance, however don't emit greenhouse emission.
How much alternative energy sources should contribute?
Till 2050, one-third of the world's electricity will need to come from wind, sun and other renewable assets.
Who says?
"British Petroleum and Royal Dutch Shell", of the arena's largest oil businesses. Climate exchange, population growth, and fossil fuel depletion imply that renewables will need to play a larger function in the future than they do today.

Scientists will currently simulate arched frame of reference during a science lab
Curving frame of reference is incredibly tough to try and do, synthetically. It’s straightforward enough through the classical suggests that — collect a bunch of mass somewhere — however to come up with a curve steep enough to own measurable effects on single quantum particles needs densities found solely close to black holes and also the like. c frame of reference during a additional direct means, with magnetic fields or “exotic matter,” has been projected in halls as holy as those at National Aeronautics and Space Administration — however such technology would enable North American nation to create a literal warp drive, and if humanity had patterned that out you’d have examine it here by currently. No, rather than working out a way to really curve frame of reference, a German research worker named Nikodem Szpak could have found a loophole that lets North American nation study the results of arched frame of reference while not having to truly curve it.
To go forward with this story, you’ll got to either acquire a high-level arithmetic degree or settle for the subsequent statement on trust: ultra-cold atoms (and since heat is simply atomic movement, you'll be able to primarily scan that as ultra-stationary atoms) caught {in a|during a|in an exceedingly|in a terribly} very specific optical lattice (laser-field) behave overall during a means which will be associated with the movement of quantum particles through frame of reference. That’s an enormous statement, thus let’s undergo it piece by piece.First, the atoms and also the lattice. this system uses multiple lasers to primarily produce advanced interference patterns with deliberately spaced peaks and valleys — areas of high or low energy intensity. The ultra-cooled atoms can naturally represent the valleys attributable to physical science — and whereas they're ultra-stationary, quantum physics says they must still be able to “tunnel” from place to put. The atoms should be ultra-cold so all or just about all their movement is attributable to this tunneling impact alone. If it is, then the general pattern of movement through the lattice will represent the interaction of quantum fields and frame of reference.
Really, the sole alternative truth to interiorise here is that, by craft the lattice to make a really specific pattern of peaks and valleys during which the atoms could move, the researches will amendment the values for his or her frame of reference figure. One lattice would possibly simulate the quantum field’s interactions with flat frame of reference (which technically doesn’t exist however which might be most closely found in deep, deep, region off from any massive masses), whereas another would possibly simulate a extremely crooked space of house, sort of a spot terribly close to the surface of a star.
The potential effects of this analysis ar prosaic, a minimum of within the short term. this can be one amongst those intersection breakthroughs, the type that doesn’t very get you anyplace however rather reveal several new avenues of analysis. having the ability to review the interaction of quantum theory and Einstein's theory of relativity (gravity), even indirectly like this, may inform work on everything from house thrusters to a grand unified theory of the universe.
By employing a figure for frame of reference curvature, instead of ever-changing that curvature directly, the researchers may provide future scientists the way to simulate the state of frame of reference at the event horizon of a region, or throughout the terribly earliest instants when the large Bang. All that might be needed is that the correct interference pattern to regulate the distribution of the foremost probable tunneling spots (valleys). And by slowly ever-changing the interference pattern over time, researchers may even watch the results of continuous variation therein frame of reference — say, attributable to growth within the universe’s earliest moments. Note that there's plenty to review regarding quantum fields and house time that doesn’t have to be compelled to do with such small-scale movements of quantum particles, and this system wouldn’t be abundant use in learning those. this can be by no means the top of Einstein’s beef with natural philosophy.
There’s no thanks to predict however physicists would possibly apply this breakthrough, however no matter they are available up with may fine be monumental. The interaction between quantum phenomena and Einstein's theory of relativity is essentially the goblet of contemporary high-level physics, and it should have simply gotten an entire heap easier to review. may this be the underpinning of some future Grand Unified Experiment? presumably. additional probably, it'll inform the trendy understanding of quantum and relativistic physics, and hopefully bring them nearer to uniting once and for all.

Cold fusion reactor is Far better than gasoline
"Cold Fusion Reactor" as compared to gasoline can produce 1 million times greater energy density.It is verified by a third party researcher.
"LENR is absolutely nothing like either fission or fusion. Where fission and fusion are underpinned by strong nuclear force, LENR harnesses power from weak nuclear force — but capturing this energy is difficult. So far, NASA’s best effort involves a nickel lattice and hydrogen ions. The hydrogen ions are sucked into the nickel lattice, and then the lattice is oscillated at a very high frequency (between 5 and 30 terahertz). This oscillation excites the nickel’s electrons, which are forced into the hydrogen ions (protons), forming slow-moving neutrons. The nickel immediately absorbs these neutrons, making it unstable. To regain its stability, the nickel strips a neutron of its electron so that it becomes a proton — a reaction that turns the nickel into copper and creates a lot of energy in the process."
HZY
First we have to understand what cold fusion reaction is?
Actually It was supposed to be a hypothetical Nuclear reaction more specifically fusion reaction that would take place at room temprature without giving so much heat energy as it was required in case of hot fusion reation that naturally take place in the stars as well as sun.
Nasa is working on this technology and scientists are developing clean and safe low energy nuclear reactors (LENR)

Andrea Rossi’s E-Cat — the device that purports to use cold fusion to generate massive amounts of cheap, green energy – has been verified by third-party researchers, according to a new 54-page report. The researchers observed a small E-Cat over 32 days, where it produced net energy of 1.5 megawatt-hours, or “far more than can be obtained from any known chemical sources in the small reactor volume.” The researchers were also allowed to analyze the fuel before and after the 32-day run, noting that the isotopes in the spent fuel could only have been obtained by “nuclear reactions” — a conclusion that boggles the researchers: “… It is of course very hard to comprehend how these fusion processes can take place in the fuel compound at low energies.”
This technology can be used in planes,homes,cars in short as an alternative of gasoline and other means of power generation.When this technology will come in the market after getting published,there would come a revolution in the technology.

Cars Can now be Parked by itself by finding a spot.
Valeo uses a dozen ultrasonic sound-wave sensors, 360-degree cameras and a laser scanner.
With a thumb swipe on a smartphone, your car one day will be able to drive into a parking deck, find an open spot and back into a space all by itself.
Technology being honed by French auto parts maker Valeo uses a dozen ultrasonic sound-wave sensors, 360-degree cameras and a laser scanner to safely park within a few centimeters of other vehicles. Then, when you re done with dinner or a business meeting, the car will return to you after another swipe of the thumb.
The potential benefits are plenty. More orderly parking means less congestion. Drivers are spared the time and frustration of the hunt for a spot. Parking lots can squeeze more vehicles into limited space.
The fully-automated system called "Connected Automated Valet Parking" is still about a decade away, however. More states must permit driverless cars and regulations have to be crafted. Equipment needs to be rolled out.
Still, Valeo executives see it as a big step toward the day in the distant future when cars actually drive themselves with no one behind the wheel.
Other companies have already demonstrated self-parking systems, but in most cases the driver has to find the spot and activate the system to make it work. The Valeo system, demonstrated Monday at an intelligent vehicle conference in Detroit using a Land Rover SUV, allows cars today to do tasks currently performed by human valets.
"The car is able to do a much better parking maneuver than we as humans," said Amine Taleb, Valeo s project manager for advanced driver assistance systems.
Here s how it works: Drivers approach their destination and the system finds a deck with an open space. The driver goes to the deck and activates the system. The deck then tells the car where the open space is. The sensors, cameras and laser activate, letting the car drive itself about 3 miles per hour, winding its way to the space and backing in. The system can even find a space on its own without a signal from a deck.
The system won t let the car hit anything, Taleb says. And it can brake and even take action on its own to evade a hazard such as another moving car. A driver can even watch the car park through the cameras and software that simulates an aerial view.
Although the technology is already available, there are hurdles. Only nine states allow driverless cars on public roads, and then only for testing purposes, said Scott Belcher, CEO of the Intelligent Transportation Society of America, the group holding the conference.
Also, parking decks will have to be equipped with systems to communicate with cars. Radio frequencies haven t been allocated yet by the federal government. The auto industry is vying with the cellphone industry for the bandwidth, for vehicle-to-vehicle and vehicle-to-infrastructure communication, Belcher said.
Cyber security guidelines and government regulations have to be put in place. And legal liability has to be sorted out if the car somehow gets into a wreck.
What s likely within five years is an interim step: The driver finds the space and the car then parks itself. Taleb wouldn t say if an auto company is interested in buying the self-parking system.
The traffic benefits alone are tremendous. Omno Zoeter, a senior research scientist at Xerox, says some studies show as many as 30 percent of urban drivers are looking for parking at any given time.
Eugene Tsyrklevich, the CEO of Parkopedia, an app that monitors more than 30 million parking spaces in 45 countries to help drivers park, predicts a decade of transition as cars and then parking garages adopt technology.
"Driving around looking for a space is not dead yet," said Tsyrklevich. "But it will be."

No Need for Spectacles Now.
British scientist have done a successful experiment on this thing.Now doctors can put a drop in he eye through operation which can help to FOCUS.
Scientist invented a new technique to get rid of spectacles.This invention is a drop which can be put into the eye which helps in focusing.The name of the drop is "Rain Drop".This can be put into the eye without any pain.Before the operation eye the region of the is made senseless for sometime so that during the operation eye could be still.
Actually,research work is done in the America by the American scientists but the practical is performed in the Yorkshire,a city of England.
This new technique is substitue of laser surgery.
with the advancement of age according to experts the focusing capability of eye is reduced to a much extent.But this technology is a remedy for that.
This technology is now in use in Britian and in short time would be available in whole world.
The price of the drop is 250 pounds.It is supposed that the rate of the drops would decrease soon.
A lot of people can get benefit from this technique.
