"The plane" Solar Impulse "
powered by solar energy and with which its developer, Bertrand Piccard, pl anea turn the world in 2012, completed its first flight by an hour and a half environmental technical innovation and has had a cost of $ 93.5 million.

The plane "Solar Impulse" exclusivamentepor powered with solar energy and its promoter, Bertrand Piccard plans to turn almundo in 2012, has completed its first flight by an hour and a half after landing at the military airfield in the Swiss town of Payerne. German rider Markus
Scherdel was the one who got the propellers of the "Solar Impulse" reached sumayor achievement to date, to the delight of the Swiss psychiatrist Piccard, who got the helicopter flight.

The prototype took off at a speed close to that of a bicycle, about 45 kilometers per hour, peseaque63.4 meters separate the ends of their wings the same distance as a "Jumbo" - and losmil round her weight 600 kilos, more or less that of a car.
The flight was conducted at an average speed of 70 kilometers per hour, achieved thanks to the four motors of 10 horsepower each quemueven on a plane covered with some 12 000 solar cells.
The aircraft managed to fly in December a distance of 350 meters in Dubendorf airfield on the outskirts deZúrich, at a height of one meter, while this trip has been planned at a height of about a thousand meters.
Piccard's goal is that the prototype at a cost of 93.5 million, bypassed the world with five stops in five days within two years. However, the next challenge goes through an overnight flight scheduled for later this year, whose technical findings apartirde will build a new unit.

This project, which required five years of work, including simulations and construction, aims to demonstrate the potential of renewable energy, promote their use and demonstrate the energy savings can be achieved through new technologies.
In 1981, another solar ultralight aircraft with a pilot on board, called "Solar Challenger, flew from France to England in five hours. Piccard, an adventurer and grandson of the inventor of the bathyscaphe, Auguste Piccard, became in 1999 the first man to circumnavigate the world nonstop in a balloon.

cheap and portable device for wound healing (MIT)

---

Monday, March 22, 2010

MIT has developed a cheap and portable device that can help speed the healing of the wounds suffered by victims of major natural disasters. The device, which was developed after the terrible earthquake that hit Haiti, is not nothing but a simple bellows pump connected to a tube, applied to a wound dressing, can generate negative pressure enough to accelerate the healing of a wound. Best of all, it costs only $ 3 and can be manufactured almost anywhere.


mid-February, four weeks after the earthquake of Haiti, a team from Brigham and Women's Hospital in Boston, specializing in the treatment of injury, traveled to the devastated capital of Port-au-Prince. The purpose of the trip was to help local physicians manage the large number of patients who had open wounds, amputations and crushed limbs. Zurovcik Danielle, a graduate student at MIT was in the team, and had brought with it a device developed as part of his thesis research: a version of low cost and portable negative pressure devices that are commonly used in hospitals to accelerate healing of wounds. The device invented by Zurovcik costs about $ 3, and its creator believes it is able to improve the care patients receive once the emergency phase within the relief, when they begin surgery to save misguided or even members the patient's life.

The device invented by Zurovcik costs about $ 3.

Robert Riviello, a surgeon at Brigham and Women's and collaborator Zurovcik, says his experience in Haiti and other large earthquakes indicates that "after carrying out emergency response, such as amputation or treatment of fractures, the main problem facing the physician are the wounds." In these treatments, which often extend for weeks or months, the negative pressure therapy to help reduce the need for dressing changes continuously. Instead of two or three shifts a day, you can make two or three a week. And this is a great advantage where resources and medical staff is scarce. Although many people do not know, over the last decade these negative pressure devices have become a central part of therapy injuries in the United States. The results show that up to three times can accelerate wound healing and in some cases, depending on the type of injury, even eliminate the need for plastic surgery or skin grafts.

Oddly, scientists do not know exactly how that negative pressure can accelerate the healing process, but assume that possibly help eliminate fluids and bacteria that build up the wounds, while increasing blood flow in the area. In addition, binds the edges of the wound and mechanical pressure exerted on it, some can cause cell growth. But the commercial versions that are used to treat burns and chronic wounds such as decubitus ulcer or diabetic foot ulcers are expensive (over $ 100 per day of use), heavy (more than 5 kilograms) and require a power source to function.

Zurovcik
The device costs only three dollars and is activated by applying pressure through a bellows pump that weighs less than half kilo. "It's basically a toilet plunger, and yet can produce a negative pressure over a long period of time, that's really impressive," says Kristian Olson, a doctor at Massachusetts General Hospital. "Not only see it as a product for those in developing countries, but I really could improve treatment in the U.S., "he adds. Riviello thought Zurovcik and test your device in Rwanda, when the earthquake struck Haiti. Boarded a plane, and soon were working in emergency tents filled with patients. His team responded primarily to those who needed follow-up care.

Of the hundreds of patients evaluated, the researchers selected eight individuals with multiple injuries, including amputations, open tissue injuries, open fractures, crushing injuries and infected surgical wounds, and were treated with negative pressure device. The treatment allowed to keep the wounds clean and reducing the need to change bands-something that is painful for patients. Once the emergency, Zurovcik turned to make adjustments to its prototype, trying to further improve the pressure seal and the amount of negative pressure that can provide. The MIT team has shown that, at times, have a good idea is much more effective than having a huge budget. Seen

carbon nanotube reaches the roof

carbon nanotubes (MIT)

---

Engineers and scientists at MIT have found a new way to generate electricity. The process takes place from power plants capable of generating wave energy, which is carried by carbon nanotubes inside the device. This system could be used to develop a whole new class of tiny generators, ideal for use in small electronic devices or even within the medical or environmental sensors.


specialists at the Massachusetts Institute of Technology (MIT) have made significant progress by exploiting a previously unknown phenomenon, but that could change the way we generate electricity. It is a system capable of producing significant amounts of energy from a tiny gadget-well over smaller than a grain of rice-built based on carbon nanotubes. Essentially, the device consists of a series of nanotubes coated with a layer of fuel. In the same way that a light body may travel along the surface of the ocean-driven waves, thermal waves generated on the surface of microscopic carbon fibers can travel through them and create an electrical current. This is a new way to produce electricity, which could lead to a new area of \u200b\u200bexpertise in the energy field and whose main practical application would be, at least in principle nanoelectronic devices.

The news was announced through a press release from MIT, and then published in specialized magazines such as Nature Materials. The scientist in charge of the team that performed the work is Wonjoon Choi, a doctoral student in mechanical engineering from the Institute. In its letter Choi explained that the electricity generation process occurs when the nanotubes are coated with a layer of a fuel jet that can produce heat for decomposition. This fuel is ignited when lit at one end of the nanotubes using a laser or a high voltage electric spark. The combustion heat generated in the form of a thermal wave travels fast moving through nanotubes at high speed, about 10,000 times faster than any other chemical reaction "conventional." The temperature rises to about 2700 degrees Celsius, and the heat generated by combustion provides the energy required for electrons begin to move along the carbon nanotubes, creating "a considerable power."

The electrons move along carbon nanotubes.

The amount of energy released in this process is much greater than that provided by traditional calculations in the field of thermoelectric waves. This was already noticed by experts in the initial experiments. Engineers, stunned by magnitude of peak voltage resulting after turning on the fuel cladding in carbon nanotubes, redoubled their efforts to understand the detail and optimize this new phenomenon. Other materials, such as semiconductors, which have the property of producing an electric potential when heated (known as the Seebeck effect), but it is a completely different principle discovered carbon nanotubes. According to the explanation of the researchers, these devices there is an "electron drag" due to the ability of the thermal wave has to "take" with her over the microconductos created by the nanotubes. All this helps to achieve high power it is capable of generating the system.

is too early to speculate on the real scope of this new way of generating electricity, but given the small size of the device and its large capacity, scientists believe that these generators could be used to power tiny devices to be implanted in the human body or as part of remote sensing. Choi Wonjoon team says that even could be used to generate alternating current. Without doubt, this is a discovery that could revolutionize the way we feed our equipment.

U.S. scientists have created a smart, green coating roofing that attracts or repels sunlight to maintain the temperature inside the house. The invention has been presented in the first round of the 239 annual meeting of the American Chemical Society (ACS), held in San Francisco (USA) until February 25.



Until now, one could choose between a light-colored roof, which repels sunlight and reduce air conditioning bills in summer and increases in winter heating, or a dark shingles that attract the sun and reduce heating costs in winter, but literally "fry" the roof in summer. However

resurfacing, manufactured from waste oil from fast food restaurants , can "read" a thermometer and "decide" if it repels or absorbs solar heat outside temperature according dela. "This is a coating materials developed more innovative and practical to date ", says chemist Ben Wen, lead author of the project. "Even by reducing or increasing a few degrees the temperature of the roof can make a big difference in the energy bill," he adds.

The coating is obtained by processing used cooking oil to form a liquid polymer that hardens like plastic. The product is odorless, nontoxic and flame retardant , and can be produced in any shade from light to dark. The chemists hope to market the product within three years and notes that its price will be lower than currently used coatings.

smart capture transparent solar panels in the windows energy to reduce pollution

---

Energy Solar is one of the most promising alternative sources of the world and is already used in many places on a small scale. But like other "clean" energy, also has its flaws. One is its low efficiency, which requires installing many panels to capture a reasonable amount of energy.

Another disadvantage is that you can place anywhere because its design does not match anything. Both problems are about to disappear, thanks to a new type of solar panels transparent "Sphelar", composed of hundreds of tiny silicon spheres of 1.8 mm in diameter that catch the rays from all angles.

This technology allows any glass surface (which abounds in buildings in big cities) will become a potential source of solar energy. Although not 100% transparent, due to its silicon balls, these films will spend an appropriate amount of light to illuminate interiors.

This innovation, introduced in the PV Expo 2010, for the undertaking Kyosemi Corporation, which rose a video explaining these panels that promise to revolutionize the solar energy market.

aircraft propeller

The propeller engine led aviation to one of his early achievements. Those initial noisy engines were soon replaced by turbojets, although less noise, are insatiable consumers of fuel. The high costs of this are now pressing the airlines to look for greener alternatives.

Rolls-Royce has redesigned the historic technology, making it less noisy and more energy efficient.

The company says the new rotor design can lower the bill for fuel for airlines about $ 3 million and reduce CO2 emissions by 10,000 tons per year and aircraft, in devices between 100 and 200 seats.

several years now turboprop engines experienced a renaissance that was not beyond largely because they were more noisy. The greater involvement with the environment is leading aeronautical engineers that the engine "open rotor" have a new opportunity.

Noise reduction is achieved by adding more blades to rotors and changing its shape, which is thinned. The company claims that this is achieved by rotating operating at lower speeds, reducing noise while maintaining a high eficiencia.Y the improvement is more remarkable because the new design uses two propellers near the rear of the engine that rotate in opposite directions, reducing consumption and the second group of propeller receives air from the first recovering energy and producing more force.

Rolls-Royce is not alone in this innovative project, General Electric, Pratt & Whitney and Snecma are also working on prototypes of a helix.

Air transportation produces about 2-3% of total CO2 emissions and the distances traveled by passengers increasing at a rate of 6-7% annually. This means that in a long-haul travel, aviation introducing cleaner technology, it provides a great impact.
also seems clear that, whenever possible, is preferable to improve the existing technology as the implementation cost is much less than that required by major changes, often because of the hindrance observed in updates very convenient and healthy global society (and I think in the hydrogen car, without going further). And, remember: oil, wherever you are, is a worldwide resource to exploit a few, but when it's over, end for everyone. The air, meanwhile, is a common good that we are obliged to share.

clean pools with solar power plants






in NASA missions to the moon, the U.S. space agency used a technology that could be kept pure and clean water as a source of energy was the sun That same technological base has been used to develop an ecological wastewater treatment plant for pools with a floating system that allows you to capture solar energy and a metal electrode that prevents the growth of microorganisms releasing mineral ions.





Clorotron is called and is formed by a solar panel Unsinkable that allows you to capture the energy, and a metal electrode that releases ions that prevent the growth of microorganisms in the water, according to reports from the brand itself. Photovoltaic solar panel converts the sun's rays into electricity, which generates an electrical current of low voltage, harmless to swimmers who achieved the release of the ions.

Thus, water purification does not require the use of chlorine and algaecides, avoiding harmful effects to the eyes or skin. Clorotron is designed for pools of 40 square meters and the price is about € 385.

mic preamps with reverb and delay

mic preamps with reverb and delay

This microphone preamp with reverb and delay, is very useful for videorockolas with Karaoke, it gives the necessary effect to the voice, and makes it more attractive.

Video tutorial showing the process that circuit assembly

Due to the success of the video jukebox, manufacturers have begun to enrich the machine with other services such as: Radio, TV and Karaoke. For the latter audience for this project, which aims to give a sound more attractive to the karaoke singer's voice. The reverb and delay, are basically signal delays, added to the original sound, which give depth to the sound.

materials for this project are very economical with the exception of the integrated ES56033E , which can be supplied on Littlediode.com in local stores is somewhat limited. Remember to print in addition to the printed circuit mask to have her phone components when assembling the card.

After printing the printed circuit on Bakelite, the technique of ironing , or screen printing technique , proceed to put all the resistors and jumpers (jumpers .)

Weld correctly, you must join welding, soldering and the workpiece at the same time. Remember that the weld quality depends on the success of any electronics project it undertakes.

Although not essential, is recommended to place a 16-pin base for the integrated circuit. This is useful if you want to change it to malfunction or any other reason, can do so quickly and without damaging the tracks, as one integrated removing many feet is no easy task.

The use of connectors is very convenient at the time of maintenance of the circuit, or disassembled for mounted on another unit. We used molex connectors are of good quality and very aesthetic. If you do not use connectors, you can solder wires directly to the PCB holes.

2N5551 transistors (NPN) are widely used for low noise preamplifiers. Double check the position before welding mask looking at the components.

This circuit operates on 12 volts DC, and support up to 50v ceramic capacitors, for this is not specified voltage. In addition, all ceramic capacitors so as polyester, are above this voltage.

We can see the polyester and ceramic capacitors placed. They have no polarity. To view the photos larger, click on them.

Now put the electrolytic capacitors. These are polarity. Components in the mask shows the direction of the condenser, and condenser brings a strip that shows the negative. Addition when new, bring negative leg shorter.

C5V6 zener diode is a diode 6 volts. It feeds the integrated circuit, since the ES56033E only needs 6 volts to operate. The 12v preamp is attached to the integrated circuit of reverb and delay.

We put

50K potentiometers and wash the card on the side of the tracks with thinner, to prevent short welding particles that can be attached to the PCB.

LOW PASS FILTER FOR SUBWOOFER AMPLIFIER 200 WATTS

LOW PASS FILTER FOR SUBWOOFER

The low pass filter, as its name implies, allows the passage of low frequency and high frequency limits. Regardless of the frequencies that fall, only allowing frequencies will pass the filter. Video tutorial

construction of low pass filter

Given that spaces are becoming more limited, the owners of the shops and bars in the city, now require that videorockolas are small and glue on the wall. In addition, speakers are not as great as before. For this reason, the subwoofer has become indispensable to recover the lost low by the small size of the stereo speakers.
This circuit, connected to a mono amplifier and speaker using an air suspension, becomes the basis of a good subwoofer.

after downloading the PDF of the page, print the printed circuit on Bakelite, either technique ironing, or screen printing. Remember that the form is ready for screen printing. If you want to print Ironing with the technique, reverse (mirror mode). I remember reading

section recommendations before doing this project.

Taking the form ready, place the resistance of 100 k and 1k, with the leftovers of the legs, make the jumper.

Weld correctly, you must join, welding, soldering and workpiece at the same time, and proceed quickly to avoid damaging the components. Remember that the weld quality depends on the success of any electronics project it undertakes.

the photos to see larger, click on them.

recommend using a base for built-in 8-pin, in order to facilitate change for maintenance or to try another operational amplifier.

horn is so easy to change without damaging the printed circuit tracks.

Then place the ceramic capacitors, which have no polarity.

Since ceramic capacitors support up to 50 volts, no need to specify the voltage in the list of materials, since the low pass filter is supplied with + / -12 volts.

Although ceramic capacitors are used in high frequency circuits or grounding, in this case its function is to prevent the leakage of noise from the source.

Place a 0.22 microfarad capacitor polyester, keep in mind that the higher the capacitor, high frequencies are less restrictive, and the lower its value, it restricts the passage of high frequencies. This depends on individual taste.

For the low frequency cut is complete, remember to use an air suspension speaker, particularly to reproduce low frequencies. In addition the speaker is also important. Please note all these details to obtain an excellent result.

Now place the electrolytic capacitors, taking into account their polarity marked on the mask components.

components in the mask shows the direction of the condenser, and condenser brings a strip that shows the negative pole. Moreover, when they are new, bring negative leg shorter.

Place TL071 integrated circuit, taking into account the position shown in the mask components.

The TL071 is a J-FET operational amplifier ( field effect transistor junction ) low noise, high speed, high voltage bipolar transistors, especially in a monolithic integrated circuit.
This device is characterized by its low power consumption, low temperature and pressure compensation coefficient.

Feeding a low pass filter is symmetrical, so we recommend making symmetrical source regulated, which is in the projects section of our website. If a transformer fails with central TAP, can make voltage doubler that is in the PDF of the microphone and preamplifier, using a single transformer.

can tweak any of the amplifiers of the page to leave monophonic and make their own subwoofer, accompanied by the low pass filter.
