Artificial muscles Can Generate Electricity to Charge an iPhone

Combining breakthroughs in self-healing materials and artificial arms, University of California, Los Angeles researchers created such muscles that can generate electricity. The research could be used to make walking robots and develop better prosthetics that juice your iPod. Part of the technology is already being used in Japan to charge batteries using ocean waves.Artificial muscles that are currently prevalent are made of metal-based film that often tears resulting in muscle failure. The new artificial muscle developed by the University of California researchers is made of carbon nanotubes as electrodes. The carbon nanotube seals the region around it once it fails preventing the fault from spreading to other regions. The researchers used flexible carbon nanotubes as electrodes instead of metal-based films that fail after repeated use. If an area of the carbon nanotube fails, the region around it seals itself by becoming non-conductive preventing the fault from spreading to other areas.This muscle conserves about 70 percent of the energy you put into it.

How To Transform Your Window Into Solar Panel

In 2007 Traditionally, solar panels for buildings have predominantly been stand alone systems mounted to roofs in order to capture sunlight.A new transparent building integrated photovoltaic technology is being funded by National Institute of Standards and Technology which would allow windows and other building integrated applications to get converted into solar panels which will capture sunlight directly and convert them into power. That means no uglier looking stand alone panels but with the BIPV technology your own windows and roofs could be converted into solar panels.National Institute of Standards and Technology has invested $4.7 million to develop technology that would allow windows and other building applications to be converted into solar panels.Konarka Technologies and Air Products will aim to find ways to develop future applications for this technology that would undoubtedly be welcomed by home owners and the renewable energy sector. Konarka will use the funds to further develop its patented, transparent, metallic grid electrode technology for the new cell and module architecture while Air Products will develop high-conductivity polymers with more efficient charge injection capability in Organic photovoltaic (OPV) cells. OPV technology is unique among solar energy alternatives as it has the potential for selecting materials for varying levels of transparency, capable of absorbing narrowly or broadly in one or more regions of the visible and near-infrared spectrum.If the companies are successful, the technology will become suitable for varied use. By regulating the wavelength of the light passing through, the windows will be able to control light for privacy and also conserve energy. Given its character, the material developed will be able to conserve sunlight inside as well as outdoor.

Silicon Solar Cells With Liquid

A company of California developing a ultra low-cost thin-film solar power modules based on a propriety silicon-ink process, has developed crystalline silicon solar cells with liquid.This company essentially creates silicon nanoparticles, inserts them into a solvent, and then pours the solvent on a substrate. The solvent is then extracted. What is left can sort of be analogized to a snowflake or a large sugar cube: a highly organized structure made up of tiny parts.Crystalline solar cells have higher efficiencies than thin films. Commercial crystalline panels can convert up to 22 percent of sunlight into electricity, without concentrators. CIGS makers are initially shooting for the mid to low teens. The catch is that making crystalline solar cells is expensive. The patterning and other processes is similar to what is used in making LCD panels. Innovalight says it could conceivably cut the production price by around 50 percent or more. Many start-ups, however, had hit bumps in bringing new (albeit different) manufacturing techniques for solar cells to market.If it is so energy-efficient why no other companies have tried to produce them? Well, making crystalline solar cells is expensive. In fact the patterning and other processes is similar to what is used in making LCD panels.The company has just raised $28 million from Convexa Capital Apax Partners, ARCH Venture Partners, Harris & Harris Group, Sevin Rosen Funds (Burke is a former Sevin Rosen partner) and Triton Ventures, among others. Part of the money will be used to build a 30,000-square-foot manufacturing facility in Silicon Valley.Innovalight hopes to start selling solar cells in the second half of 2009. By 2010, the company hopes to be cranking out "tens of megawatts" worth of solar cells from the facility.

Low-Cost Organic LED Production-OLED Technology

It is not just the fact that modern green technologies and solutions aim at producing ways of harnessing energy from the renewable and clean energy sources, but they also are focusing on the conservation part of energy. They are working on the simple principle that energy saved is energy produced and in this regard, LEDs have played a very important role in the past few years. When it comes to making sure that lighting technologies are conserving energy, they have made a quantum leap from the traditional sources and methods.LEDs (or Light-Emitting Diodes) will slowly become the lighting standard over the next decade. But light bulbs won’t be the only products to take advantage of their efficient properties. A variety called OLED (or Organic Light-Emitting Diode) are thin, organic materials sandwiched between two electrodes, which illuminate when an electrical charge is applied. This technology is behind all those cool flexible displays and electronic ink displays we’re always seeing. They’re so thin, that they could be applied to rooms as a type of wall paper to glow at the touch of a finger or when someone enters the room.The challenge in producing these OLEDs is that they also have to have potential to be made at a very low cost, because they can be printed “roll-to-roll” like a newspaper. GE recently demonstrated the first OLEDs to be made in this manner. Apparently, the researchers worked for four years on this project. The project still has a long way to go before making sure that the OLEDs are ready for commercial use.The process of commercially manufacturing OLEDs has remained expensive. However, a recent breakthrough from GE hopes to lower the cost-barrier and show that OLED can be created “roll to roll”.

Fuel-Cell Powered Cargobike - Hydrogen bike

We’ve seen motorbike concepts powered by small fuel cells, but this is the first time in my memory that a full-scale commercial test of such technology has actually gotten off the ground.Clean Air Bike is the result of a joint-venture between Masterflex and German bike maker Hawk. It is claimed the Cargobike can handle loads up to 150 kg and one fuel cell lasts for 250 kilometres powered by only 90grams of hydrogen within a 2.2kg storage unit. With a motor rated at 250 watts it's exempt, just like a ‘normal' bike, from European vehicle registration laws .Potential uses include postal delivery services, city cleaning divisions, large industrial site transport and tourist applications.Masterflex say that not only does the fuel cell technology provide sufficient power for the motor but that there is enough surplus for secondary functions such as lighting or cooling for transporting temperature sensitive goods. Potential uses include postal delivery services, city cleaning divisions, large industrial site transport and tourist applications.Hydrogen powered fuel-cells have often been talked up as one of the solutions to the problem of global warming caused by transport CO2 emissions from fossil fuels. The technology uses compressed hydrogen gas to produce emissionless power at the point of use. But debate has centred around how best to extract and store hydrogen from the natural world. One of the greenest methods, but one that is still being developed, is to extract the hydrogen directly from sunlight without using any fossil fuels in the process, potentially delivering a totally green transport fuel.Of course, practical use of this vehicle is limited to the nearest hydrogen station — but manufacturers are confident such infrastructure will become available once companies latch onto the advantages of fuel cell technology.source

Sun Energy Clean Up Your Water Sources

The SolarBee incorporates patented near-laminar radial flow technology that provides high-flow, long-distance circulation™ (LDC) to improve water quality in freshwater lakes and reservoirs, potable water tanks and reservoirs, wastewater ponds and lagoons, and estuarine environments.What is amazing about this technology is that it uses the energy of the sun to clean up water sources. It cleans up both stagnant and flowing sources by making sure the water in it circulates regularly and uses a very natural way to purify the water. The technology is one of its kinds in the world and saves on plenty of electrical and chemical resources that are otherwise used to purify water. The list of water resources that this wonder device can keep fresh and clean is both long and impressive. It can be used in every kind of water source and has a very impressive track record when it comes to practical utility.Each solar-powered SolarBee unit can displace the mixing energy of about 30 horsepower of conventional grid-connected mixing equipment in wastewater treatment ponds, and can displace high horsepower aeration/mixing equipment in freshwater reservoirs and other water bodies. The energy savings from each unit is the equivalent to about 220,000 kW hrs per year, or the annual energy requirements for about 20 homes or 25 passenger cars, thereby reducing equivalent carbon dioxide emissions (the leading Greenhouse Gas, GHG) by about 150 tons per year.With the world constantly struggling to maintain its water resources, such technology is both welcome in regards to sustaining and maximizing the existing water resources .The high efficiency and completeness of SolarBee circulation can reduce up to 80% of the chemical requirements in potable water systems. In freshwater lakes and reservoirs, chemical savings includereducing or eliminating the need for algaecides and herbicides, as well as phosphorus-binding compounds such as alum. Municipal raw water storage reservoirs can benefit from greatly reduced powdered activated carbon (PAC) requirements. Reducing chemical usage benefits both the environment and economics.It is both innovative and very energy efficient. Hopefully, such technology will catch on and make its way across the planet. We do need to keep our planet green and blue; this helps the blue part immensely.The SolarBee represents the most innovative, energy efficient and environmentally friendly technology on Earth for providing beneficial, long-distance water circulation

Driveway Solar Light

There are many solar products on the market today, one very popular item is solar lights, either for a driveway or walkway.In the crucial phase of power-crisis, it’s interesting to know that more and more products are flushing in the markets that just use solar energy to operate. Latest in this series is ‘Solar Walkway Lights’. In the daytime, these lights soak up sun energy and light up when the night wears on. Interestingly, these walkway lights are strong enough to bear heavy weight of a vehicle, even. Therefore, having it on the both sides of driveway or walkway is, indeed, an energy-efficient way to add to the safety and beauty of our surroundings.In my opinion this solar light it is a very good product.This solar light will be all over the driveways.

Solar Notebook Concept

This solar notebook concept is a laptop with complete power independent. Its independence is due to powerful batteries that are recharged by wide Solar Panel attached to the computer. Equipped with satellite link GPS, internet access, and satellite telephone which makes this device not only power independent but also universal tool for communication and exchange information literally from any spot on the planet.The detachable panel is to be put away in the sun for recharging while the notebook functions on a smaller battery that charges itself when DC power is plugged into the system.The solar panel may be completely detached from the main body to be put away for recharging, then smaller battery inside the computer is on.This sure do will come in handy for scientists or researchers who work far away from civilization and power source.

What Is A Human Electric Hybrid Vehicle?

In the 21st century humanity will have to evolve through a more efficient way of life as our resources are beginning to be insufficient for our needs.You power the generator and theelectric motor drives the vehicle. You can also drive it as an electric vehicle if you don’t want to or are unable to pedal your self.This Human Electric Hybrid Vehicle uses the power of your muscles as well electricity stored in the batteries. It allows smooth and constant velocity both uphill (with the help of the electric motor), as well as downhill (when the wheel acts as a generator and charges the batteries). The vehicle can turn 360 degrees maintaining stability all the time. Additional power is acquired from photovoltaic placed on top of the vehicle as well as during de-acceleration from regenerative braking. Elderly and handicapped people that are unable to provide enough kinetic energy can also charge the batteries directly from the grid. A vehicle such as this makes extensive use of renewable energy possible and lead to a more sustainable fossil fuel future.

It fits perfectly in your shirt pocket and you can almost use it anywhere. Since it is powered by the sun you will not have to worry about how you are going to carry this around and keep it working. So take purity in your pocket across the planet.

Now Honda Goes Solar Cells!

The Honda Motor Company, best known for it’s super smooth cars and motorcycles, is all set to promote solar energy in a big way with its venture called Honda Soltec company that makes solar panels. What this essentially means is Honda, which has long been promoting eco friendly technology will give solar energy a huge push thus changing the way the game is played. The Honda Soltec factory estabilished in November, 2007 is mass producing solar panels in a massive scale and it wouldn’t be very surprising if Honda launches a solar powered car in the near future.They began mass-producing the cells last fall and have already created a solar-powered hydrogen filling station in Torrance, CA. The power generated at the station creates the hydrogen for Honda’s concept FCX, an all-hydrogen vehicle that emits only H2O.Honda committed to reducing worldwide CO2 emissions in 2006 and they took this pledge into consideration when making the cells. Honda reports that their materials and their process reduce the energy used to make the cells by 50% over standard solar. Ideally, this process would make cells cheaper, but I didn’t see any pricing data.With a Global manufacturing giant like Honda trying to make solar technology popular, it is just a matter of time before other big manufacturers fall in line. The future for our fragile environment is looking brighter.

Battery Charger From Steam-Power

From the "how the heck did they do that?" department comes a fascinating example of human ingenuity: a steam-powered battery charger.The project makes use of a “Look Out” brand boiler from the 40s, a 6 HP steam engine from 1903 and a self-made magnetic alternator that uses all that steam to generate electricity to power your batteries.This magnetic alternator charges a 48V battery bank at 120 rpm and at 200 rpm it generates 2000 Watts of power, which is pretty good considering the hardware that is involved in the DIY. The best feature of the project is that it can maintain this level of power even with low grade dead wood.The idea of getting your electricity from firewood is fascinating, but a little caution is a good thing.

DARPA Concept a Solar Plane That Would Fly Non-Stop For Five Years

What would you think if we told you that DARPA is considering a plane that would fly non-stop for 5 years without burning a single drop of fuel? They are, and it's called the Vulture program, which aims to produce an aircraft able to carry a 1,000 pound payload, pump out 5kW of onboard power, and keep up enough speed to withstand the winds it'll encounter at 60,000 to 90,000 feet.Needless to say, that's a long ways from becoming a reality, although it seems that the first phase of the project could soon be kicking off, with Vulture program manager Daniel Newman saying that they've had "at least one successful offeror," and that they're now close to doling out the first contracts. That initial phase will run for twelve months, and will require contractors to "define the objective system and design both full-scale and subscale demonstrators." That'll then be followed by phase two, which'll run through 2012 with the goal of testing of a subscale demonstrator capable of flying for three months.There are currently three options under consideration. The first one is nuclear and - wait, this is not under consideration. The second one is to refuel the aircraft in flight. This favors fuel cells because they are more efficient and reliable than internal-combustion and gas-turbine engines. The other option is solar energy, either solar thermal, which is unproven, or solar electric, which is a proven technology.

How To Produce Your Own Biodiesel:FuelMeister II

Biofuel is the way forward in terms of short term alternative to the growing fuel and environmental crisis. While I do firmly believe that fuel cells are the ultimate way forward I terms of alternate energy sources, fuel cells may not be yet ready to replace conventional fuel. Hence in as short term stop-gap arrangement biofuel is a very viable option. But one of the major problems with running on biofuel is the fact that you do not run in to a refilling station every now and then. This is one of the major reasons why biofuel is not really catching up in USA as fast as it is spreading across Europe.One problem consumer’s face when wanting to use biofuels is building an in-house processor for creating biodiesel to further shave costs. This is no small feat so Renewal Biodisel has created a second generation do-it-yourself system that makes it a snap. The system is aptly coined the FuelMeister II. The biggest benefit to this system is cost savings, producing your own biodiesel fuel can bank you as little as .70 cents a gallonThe improvements from the first FuelMeister to the second version are many, according to the makers. Some of the new features include the single tank system, making it much more convenient to put in a small shop, garage or shed. It also has a relatively slick direct catalyst injection system which increases the rate of chemical reactions making the FuelMeister capable of generating two batches per day. There is an automated water wash feature, relieving constant supervision and simple valve and tank lip operations for speed and efficiency during the process. All this added to make the whole process a lot easier for you.The FuelMeister II is faster, safer, and easier to operate than its older sibling. The FuelMeister creates biodiesel out of used cooking oil, methanol, lye, electricity and tap water. With these ingredients properly blended the FuelMeister can kick out 80 gallons of clean-burning fuel every day. This fuel can be used to power your vehicle or even your home or both.FuelMeister II makes it simple for first-time chemists and fuel chefs; the system comes complete with all of the chemical testing equipment, safety equipment, scales and procedures to assist you in making the highest quality biodiesel possible. With associated dealer support, a toll-free factory service line and total product support from multiple sources the FuelMeister II is the clear winner among the personal biodiesel processors.This fuel can be used to power your vehicle or even your home or both. So basically you can throw in all the crap and produce gallons of biofue.

Another Wave-Power Startup OreCon Dives In

Vast amounts of power are locked away in the movements of the ocean, but because of technical challenges, the number of startups that have attempted to harness wave power thus far is relatively small when compared to wind or solar.OreCon is the latest, with plans for a sort of giant, self-contained buoy that floats atop the water, each unit generating a megawatt and a half of energy. The company has raised $24 million, which it plans to use in building a full-scale example. One of the problems with putting mechanical equipment in the ocean is that the salt and other chemicals in sea water tend to destroy moving parts. OreCon uses a design called the Oscillating Water Column to keep most of the parts well above water level.The company has raised $24 million, which it plans to use in building a full-scale example.In an OWC, which is a well-known setup, the pressure from waves outside the device causes water to rise and fall within it, which in turn pushes air in and out through a turbine, creating energy. They tend to be fairly inefficient, though.OreCon’s innovation is using what it calls “multi-resonant chambers”. In its proprietary design, the company deploys multiple OWCs around a 40 meter platform that’s tethered to the sea floor a few miles off shore.The first unit should be deployed somewhere off the coast of England in Cornwall, near Plymouth, where OreCon was founded six years ago. Another one is being set up off the coast of San Francisco too. This is apparently an awesome idea if it works and one has no reason to think otherwise either.

First Green TV Station To Run On Wind Power

The mainstream media has always voiced its concern over the rise in greenhouse gases in the atmosphere but the media houses themselves have not always tried to follow what they have preached so far. NBC11 is happy to report the station has made a major commitment to going green.NBC 11 has set upon itself the noble task of saving our green planet from future climatic catastrophe by adopting green energy source to power its TV station in San Jose.The station has offset its electricity with 100 percent certified energy certificates, according to station officials.That means every bit of power used at the studios on the 2400 block of North First Street in San Jose is replaced on the grid by clean energy created by wind farms.The wind effort is part of a new campaign started by the station called "EcoLogic."The campaign is designed to educate NBC11 employees, viewers and local businesses about ways they can reduce their carbon footprint at work and at home.NBC 11 through its ‘Going Green’ page and the ecological stories is helping to educate its viewers of the importance of using clean alternative energy sources to combat global warming. Wind energy if adopted on a large scale is believed to reduce the energy bill of the consumer considerably. A landmark study of wind integration into the New York State electric power system has shown that 10% addition of wind generation can actually cause $305 million reduction in payments by electricity customers in one year.NBC11, in partnership with 3Degrees, committed to renewable energy through purchasing Green-e Energy Certified Renewable Energy Certificates (RECs) equivalent to the station’s of electricity consumption at the main studios in San Jose.This purchase has an equivalent environmental impact of preventing over 2,000 metric tons of CO2 from entering the atmosphere, or of 473 acres of forest storing carbon annually.Details of the station’s decisions and progress will be covered on NBC11 News and NBC11.com throughout 2008.In the coming months, the station will announce several ways in which other businesses and viewers can join with the station in reducing the region’s impact on the environment.

Toyota Will Offer To Make A Hybrid In 2010

Toyota has just announced that it plans on building its first plug-in hybrid by 2010. This car will be direct competition with GM’s high-profile Volt which is set to released that year. However, many pundits believe that the Volt is “vaporware” and will not be released in 2010.The 2010 plug-in will use lithium-ion batteries, the same sort of batteries that Toyota was saying were not stable enough to use in a car, and this, just months ago. But now Toyota states that it has instructed its Panasonic joint-venture battery factory to add a production line that will produce the new batteries.Toyota’s plug-in hybrid (PHEV) is basically a souped-up Prius running on 2 nickel-metal hydride batteries (the 2010 PHEV will run on lithium-ion batteries). It gets almost 100 miles a gallon in electric mode. It takes about 4 hours to charge, and it can run on the batteries for only about 7 miles. GM has claimed that the Volt will be able to go 40 miles with a single, 6-hour charge.

First Word's Greenest Museum

It is not at all a surprise that museums across the planet (unlike the ones in my home town) are opting to go the green way as they try and tell the curious minds that visit them that the future lies in going green. I suppose there is a bit of an irony when you put a section of the ‘extinct species’ in a museum room that is boasting some of the finest green features around. Makes you believe that if we were really so responsible and sensible a lot earlier, then maybe that whole section could have been avoided; at least to a large extent. This is not to say that the green features are not welcome, but just to say that maybe things could have been a lot better.From a bird’s-eye view, the domes of the California Academy of Sciences, set to open in the fall, bulge out of the ground like giant scoops of green ice cream. These undulating hills built into the museum’s 2.5-acre, flora-covered roof integrate the building into the green space of surrounding Golden Gate Park.Designed by renowned Italian architect Renzo Piano, whose works include the landmark modern-art museum Centre Pompidou in Paris, the $484-million structure will most likely be the largest public building ever to qualify for the U.S. Green Building Council’s “platinum” LEED (Leadership in Energy and Environmental Design) rating. The designation, so far held by just 70 buildings worldwide, is the highest honor in green construction.Beneath the roof, museum-goers will find a natural-history museum, a planetarium, a rain forest with free-flying birds, a coral reef inhabited by 4,000 fish, and an aquarium filled with saltwater pumped in from the Pacific Ocean. The museum is not just a green structure, but also an amazing green hub that gives the on lookers a wonderful idea of what a green tomorrow would be like and how one can maximize green qualities in a structure.

Hydro Kinetic Technologies - Hydro Kinetic Turbine

Over the last century we have realized that we can tap the energy of the flowing water, by not just merely allowing it to flow, but building up enough energy in it by stopping the flow and then harnessing the latent potential energy in it. It is this exact principle that has enabled us to construct dams and make sure that we generate power by storing water. Despite all the advantages that dams offer, they are proving to be a bit hazardous in regards to preservation of nature around these structures. They are causing problems that are as simple as flow of fertile soil to the prevention of movement of fishes in certain rivers.Hydro Green Energy's hydro kinetic turbine arrays are composed of the only truly modular interchangeable zero head current based turbines in the industry. Hydro Green Energy's dual duct axial flow interchangeable hydro kinetic turbine is covered by U.S. and International patents. Hydro kinetic technologies describe the ability to produce zero emission renewable power (energy) from the movement of water. Unlike traditional/conventional hydropower, which requires an impoundment of water usually created by a large dam, no large infrastructures are required eliminating negative side effects to the environment and marine life.The name plate capacity of the design is 250 kW per unit with a rotor diameter of 12 feet. Due to our surface suspension system, there are inherent operational maintenance and safety advantages. An on-board gantry allows for the raising and lowering of individual units in the hydro kinetic turbine array without having to conduct underwater diving and maintenance operations in extreme water velocity and near zero visibility conditions. The floating raft provides a platform for operation and maintenance workers to stand on and place equipment during activities.In a tidal energy generation setting, this advantage becomes even more pronounced since all maintenance activities typically occur within a 15 to 30 minute slack tide (the period during which the current reverses direction). From a underwater diving standpoint, the short operational window during the slack tide significantly increases the risk of injury to the divers and the potential loss of equipment.The technology is a wonderful solution to the growing troubles caused by dams across the planet. This should offer a viable solution both in regards to the energy needs of the planet and the environmental concerns that come attached with it.

Solar Powered Patio Umbrella-Invention Of The Year!

This probably is the gadget that should win the most obvious invention of the year; at least till date. This of course is by no means to state the fact that those who came up with the idea have not done anything significant, but it just tells that sometimes the simplest ideas are the most difficult to conceive. Soon, we’ll see baseball caps embedded with solar panels to charge radios or iPods; while simultaneously glowing at night. The Solar powered Patio Umbrella is pretty cool but it still leaves a lot more wanting from it.Set it up anywhere the light shines down and at night you’ll be treated to an array of “starry” LED lights to illuminate the rest of your evening.This item has a solar panel which screws into the top of the umbrella to power the 18 white LED’s which are located on the ribs.It also has a center hub light with 8 LEDs inside; there is a dual switch on the umbrella which will control both the rib lights and the hub light. You can have them both turned on you can have one or the other on, depending on how much light you want or need.The batteries inside the solar panel are replaceable and the leds on the ribs are also replaceable. The panel will charge in direct sunlight and fully charged provides 6-8 hours of light.It’s cool that the batteries and LED lights are replaceable — basically providing a long-life for this system.This creates a beautiful, star-like light effects that will be bright enough for those crucial activities like opening the next bottle of wine.

This LED Can Shine 80 Years on a Single Charge!

Running out of batteries for the flashlight can soon become a thing of the past if William Henry has his way. An applications specialist at Ireland’s Tyndall National Institute, Henry got his team of researchers to developed a way to make a lamp from micro LEDs that will shine on for over 80 years with a single charge,this LED is called micro for a reason — it's tiny.The light measures only 5 microns across compared to the 300 microns across that a standard LED measures and requires only a few billionth of an amp to operate and emit light literally through a man’s lifetime once you fully charge its coin-sized battery.But still, the technology is there, so it could be expanded to make larger, more practical LEDs that might last a less impressive but still awesome 5 years on a single charge!

How To Build Your Own Solar Box Furnace

If you love the planet, hate wasting money and are comfortable with a tool belt, then you might just be able to cobble together your very own solar powered room heater.Here is a great gadget to beat the bitter cold. And the good news is, unlike in ordinary heaters, natural gas and heating oils don’t burn deep holes in your pockets when you use the Self Powered Solar Box Furnace. Made out of odds and ends, this tool can not only heat up a small room or a detached shed, but is wonderfully easy on the environment as you must have guessed it from the name it is solar-powered, and doesn’t use any electrical controls. Let’s not make the mistake of underestimating the capabilities of the Self Powered Solar Box Furnace. It can turn a fairly large space comfortably warm on a cold, sunny day. It is possible to scale this project up to any size. A larger version of this furnace could be used to provide central heating to an entire house. Now we take a look at the mechanism of the device. It sounds fairly simple and is based on simple scientific rules. When sunrays fall on the black metal collector plate, the latter absorbs the rays and converts them to heat. Sun shining on the solar panel array powers the fan attached to the device, which pushes cold air into the bottom of the box. The cold air warms up as it passes over the collector plate, then the warmed air exits from the top of the box. What is really convenient about this is that you can customize it according to your needs and preferences. You have a wide range of choices when it comes to deciding the dimensions of the box and the materials to be used in the construction of it. The differential temperature controller ensures that you regulate the device according to your requirements and weather conditions.Now comes the most interesting part. You can actually make it yourself! Solorb.com offers you a thorough, step-by-step guide to making your very own personal Solar Powered Room Heater .The architect of the heater even says that "it is possible to scale this project up to any size. A larger version of this furnace could be used to add a lot of supplemental heat a house."

To Clean Up The Earth and Space EUROSTAR Launches 'Green Box'

There have been plenty of complaints from people across the planet that we have not only been trashing the planet, but we are also going ahead and leaving an unwanted mark even beyond the planet. Every time we make an expedition to the outer space, we seem to leave behind a trail of trash and plenty of metallic nonsense. We might not be doing much about it as of yet, but we sure can at least the components that receive the signals from the space a lot greener. That is exactly what Eurostar wishes to do and is doing.Eurostar has announced its participation at the 14th Middle East International Cable, Satellite, Broadcast and Communications Exhibition (CABSAT) 2008 being held from March 4th - 6th, at the Dubai International Convention and Exhibition Centre.This year's CABSAT will see the mega launch of the first-of-its kind satellite receiver - Green Box from EUROSTAR along with other innovative satellite products.
