Air car for India....By TATA [Cost-30p/km]



A car that runs on air could soon be a reality for Indians.
Tata Motors has signed an agreement with Moteur Development International of France to develop a car that runs on compressed air, thus making it very economical to run and be almost totally pollution free.
Although there is no official word on when the car will be commercially manufactured for India, reports say that it will be sooner than later.
The car -- MiniCAT -- could cost around Rs 350,000 in India and would have a range of around 300 km between refuels. The cost of a refill would be about Rs 90.

How does it work?
MDI explains that 90m3 of compressed air is stored in fibre tanks. The engine is powered by compressed air, stored in a carbon-fiber tank at 30 MPa (4500 psi). The tank is made of carbon-fiber in order to reduce its weight. The engine has injection similar to normal engines, but uses special crankshafts and pistons, which remain at top dead center for about 70 degrees of the crankshaft's cycle; this allows more power to be developed in the engine.
The expansion of this air pushes the pistons and creates movement. The atmospheric temperature is used to re-heat the engine and increase the road coverage. The air conditioning system makes use of the expelled cold air. Due to the absence of combustion and the fact there is no pollution, the oil change is only necessary every 50 000 km.
The car
The end product is a light weigh vehicle that can reach speeds up to 220 kmph.
MDI's vehicle's have fibreglass bodies which makes them light, silent urban car. The car's body is tubular, light weight, and is held together using aerospace technology.
The vehicles do not have normal speed gauges. Instead, they will have a small computer screen that shows the speed and engine revolutions. The system allows for infinite possibilities such as GSM telephone systems, GPS satellite tracking systems, programs for delivery people, emergency systems, internet connections, voice recognitions, map presentation, traffic information, etc.
The seatbelt system is different from what we know. One part of the belt is anchored to the floor of the car, like traditional cars. The other part of the belt, in stead of being attached to the side of the car, is also anchored to the floor of the vehicle. This helps to secure the bodies of the driver and passengers in the case of a collision.
The vehicle's electric system is also revolutionary. MDI has bought a patent that is bound to reduce the important of electrical systems in all cars. The trick consists in using a small radio signal. The system makes the car 20 kilos lighter and considerably quieter.
There are no keys - just an access card that can be read by the car from your pocket.
In the single energy mode MDI cars consume around Rs 45 every 100 km.
When there is no combustion, there is no pollution. The vehicle's driving range is close to twice that of the most advanced electric cars (from 200 to 300 km or 8 hours of circulation).
The recharging of the car will be done at gas stations, once the market is developed. To fill the tanks it will take about to 2 to 3 minutes at a price of Rs 90. After refilling the car will be ready to driver 200 kms.
The car also has a small compressor that can be connected to an electrical network (220V or 380V) and will recharged the tanks completely in 3 or 4 hours.
Because the engine does not burn any fuel the car's oil (a litre of vegetable) only needs to be changed every 50,000 km.
The temperature of the clean air expulsed form the exhaust pipe is between 0 and 15 degrees below zero and can be subsequently channelled and used for air conditioning in the interior of the car.
MiniCAT.
The smallest and most innovative: three seats, minimal dimensions with the boot of a saloon: a great challenge for such a small car which runs on compressed air. The MiniCAT is the city car of the future.
Specifications:
Airbag, air conditioning, ABS, 3 seats, 1.5 m3.
Dimensions: 2.65m, 1.62m, 1.64m
Weight: 750 kg
Maximum speed: 110 kmh
Mileage: 200 - 300 km
Maximum load: 270 Kg
Recharging time: 4 hours (Mains connector)
Recarge: 3 minutes (Air station)
CityCAT
A spacious car with seats which can face different directions. The vehicle´s design is based on the needs of a typical family.
Characteristics:
Airbag, air conditioning, 6 seats.
Dimensions: 3.84m, 1.72m, 1.75m
Weight: 750 kg
Maximum speed: 110 kmh
Mileage: 200 - 300 km
Max load: 500 Kg
Recharge time: 4 hours (Mains connector)
Recharge time: 3 minutes (Air station)
The MDI Group
The MDI Group is headed by Guy Negre, a former Formula One engineer. MDI is a small, family-controlled company, founded in Luxembourg but now located at Carros, near Nice (southern France) where Guy and Cyril Negre, together with their technical team, have developed a new engine technology with the purpose of economising energy and respect severe ecological requirements -- at competitive costs.

Air car ready for production.....Get ready

[Very handsome] ..Zero pollution!!!!
The world's first commercial compressed air-powered vehicle is rolling towards the production line. The Air Car, developed by ex-Formula One engineer Guy Nègre, will be built by India's largest automaker, Tata Motors.
The Air Car uses compressed air to push its engine's pistons. It is anticipated that approximately 6000 Air Cars will be cruising the streets of India by 2008. If the manufacturers have no surprises up their exhaust pipes the car will be practical and reasonably priced. The CityCat model will clock out at 68 mph with a driving range of 125 miles.
Refueling is simple and will only take a few minutes. That is, if you live nearby a gas station with custom air compressor units. The cost of a fill up is approximately $2.00. If a driver doesn't have access to a compressor station, they will be able to plug into the electrical grid and use the car's built-in compressor to refill the tank in about 4 hours.
The compressed air technology is basically just a way of storing electrical energy without the need for costly, heavy, and occasionally toxic batteries. So, in a sense, this is an electric car. It just doesn't have an electric motor.
But don't let anyone tell you this is an "emissions free" vehicle. Sure, the only thing coming out of the tailpipe is air. But, chances are, fossil fuels were burned to create the electricity. In India, that mostly means coal. But the carbon emissions per mile of these things still far outdoes any gasoline car on the market.
Unfortunately, the streets of North America may never see the Air Car, though; it's light-weight, glued-together fiberglass construction might not do so well in our crash tests. However, that does not mean the Air car is confined to the sub-continent. Nègre has signed deals to bring its design to 12 more countries, including Germany, Israel and South Africa.
And this isn't the last we'll hear of the technology. The folks making the Air Car are already working on a hybrid version that would use an on-board, gasoline-powered compressor to refill the air tanks when they run low. Negre says that technology could easily squeeze a cross country trip out of one tank of gasoline.

World's strongest magnet

It will be the world's strongest magnet for neutron experiments, eclipsing the 15-tesla system now in use.

The new, high-field magnet, which is based on the magnet lab's Series-Connected Hybrid concept, will be housed at the Berlin Neutron Scattering Center. The magnet will produce a magnetic field between 25 tesla and 30 tesla - more than half a million times stronger than the Earth's magnetic field, and will be finished in 2011.

The lab's Series-Connected Hybrid combines copper-coil "resistive" magnet technology in the magnet's interior with a superconducting magnet, cooled with liquid helium, on the
exterior. The copper-coil insert is powered by an electrical current, while the superconducting outsert conducts electricity without resistance as long as it is kept colder than 450 degrees below zero Fahrenheit (-267.7 C) which is pretty close to absolute zero (-273.15 C or -460 F).


By combining the power supplies of these two technologies, engineers can produce extremely high magnetic fields using just one-third of the power required by traditional magnets.

The version that magnet lab engineers will build for HMI is different in that its bore, or experimental space, will be conical to allow neutrons to be scattered through large angles. It will also be horizontal, as opposed to the traditional vertical bore of most high-field magnets.

These modifications make the magnet ideal for neutron scattering experiments, which are among the best methods for probing atoms to better understand the structure of materials.

With this new magnet, scientists will be able to carry out experiments that aren't currently possible. One of the greatest challenges in condensed matter physics is to develop a comprehensive theory describing high-temperature superconductors.

The combination of neutrons and high magnetic fields will allow scientists to study the normal state of high-temperature superconductors in the low-temperature limit. In addition, it will be possible to probe hydrogen structure in both biological and hydrogen-storage materials.

"Part of the challenge in science is figuring out how to maximize resources," said Mark Bird, interim director of the Magnet Science & Technology division. "We can't always afford to bring the tools and techniques to the magnets; sometimes we have to bring the magnets to the tools to advance the science."

The Hahn-Meitner Institute itself will thus become a magnet, with this major piece of equipment, pulling in researchers from around the world to Berlin.

Water-fuelled car


Water-fuelled car

From Wikipedia, the free encyclopedia

Jump to: navigation, search

Contents

[hide]

A water-fuelled car is an automobile that supposedly derives its energy directly from water. Water-fuelled cars have been mentioned in newspapers, popular science magazines, local news coverage, and the internet; at least some of the claims were found to be tied to investment frauds.[1][2][3][4] These vehicles may be claimed to produce fuel from water on board with no other energy input, or may be a hybrid of sorts claiming to get energy from both water and a conventional source (such as gasoline). This article focuses on vehicles which claim to extract chemical energy directly from water, a process which would violate the first and/or second laws of thermodynamics.[5][6][7][8]

[edit] What water-fuelled cars are not

A water-fueled car is not any of the following:

[edit] Chemical energy content of water

Spontaneous chemical reactions do not create energy; they release it by converting unstable bonds into more stable bonds and/or by increasing entropy. The burning of conventional fuels such as petrol (gasoline), wood, and coal converts the fuel into substances with less energy, mostly water and carbon dioxide. In the combustion of fossil fuels water is a waste product, and the overall reaction can be represented with the following chemical equation:

CnHm + (n + m/4) O2 → n CO2 + m/2 H2O

Water is such an abundant chemical compound in part because it has very stable bonds that resist most reactions. For water to participate in a reaction that releases energy, high energy compounds must be added. For example, it is possible to generate the combustible fuel acetylene by adding calcium carbide to water. However, the calcium carbide, a high energy material, is the 'fuel,' not water. Under conditions common on Earth, chemical energy cannot be extracted from water alone.[7][6] (It is theoretically possible to extract nuclear energy from water by fusion, but fusion power plants of any scale remain impractical, and no allegedly water-fuelled cars are claimed to be powered by fusion.)

[edit] Electrolysis

Many alleged water-fuelled cars obtain hydrogen or a mixture of hydrogen and oxygen (sometimes called "oxyhydrogen", "HHO", or "Brown's Gas") by the electrolysis of water, a process that must be powered electrically. The hydrogen or oxyhydrogen is then burned, supposedly powering the car and also providing the energy to electrolyse more water. The overall process can be represented by the following chemical equations:

2H2O → 2H2 + O2 [Electrolysis step]
2H2 + O2 → 2H2O [Combustion step]

Since the combustion step is the exact reverse of the electrolysis step, the energy released in combustion exactly equals the energy consumed in the electrolysis step, and—even assuming 100% efficiency—there would be no energy left over to power the car. In other words, such systems start and end in the same thermodynamic state, and are therefore perpetual motion machines, violating the first law of thermodynamics. And under actual conditions in which hydrogen is burned, efficiency is limited by the second law of thermodynamics and is likely to be around 20%.[9][10] More energy is therefore required to drive the electrolysis cell than can be extracted from burning the resulting hydrogen-oxygen mixture.

[edit] Claims of functioning water-fuelled cars

[edit] Stanley Meyer's water fuel cell

Stanley Meyer's water fuel cell[11]

Stanley Meyer claimed that he ran a dune buggy on water instead of petrol. He replaced the spark plugs with "injectors" to spray a fine mist of water into the engine cylinders, which he claimed were subjected to an electrical resonance. The "fuel cell" would split the water mist into hydrogen and oxygen gas, which would then be combusted back into water vapour in a conventional internal combustion engine to produce net energy. Meyer's claims were never independently verified, and in 1996 he was found guilty of fraud in an Ohio court.[1] He died of an aneurysm in 1998, and conspiracy theories persist claiming that he was poisoned.[12]

[edit] Garrett electrolytic carburetor

Charles H. Garrett allegedly demonstrated a water-fuelled car "for several minutes", which was reported on September 8, 1935 in The Dallas Morning News.[13] The car generated hydrogen by electrolysis as can be seen by examining Garrett's patent, issued that same year.[14] This patent includes drawings which show a carburetor similar to an ordinary float-type carburetor but with electrolysis plates in the lower portion, and where the float is used to maintain the level of the water. Garrett's patent fails to identify a new source of energy.

[edit] Aquygen

The firm Hydrogen Technology Applications has also patented an electrolyser design and has trademarked the term "Aquygen" to refer to the hydrogen oxygen gas mixture produced by the device.[15][16][17] Originally developed as an alternative to oxyacetylene welding, the company also claims to be able to run a vehicle exclusively on "Aquygen" and invoke an unproven state of matter called "magnegases" and a discredited theory about magnecules to explain their results.[18][19] Company founder Dennis Klein claims to be in negotiations with a major US auto manufacturer and that the US government wants to produce Hummers that use his technology.[20][21]

[edit] Genepax Water Energy System

In June 2008, Japanese company Genepax unveiled a car which it claims runs on only water and air,[22] and many news outlets dubbed the vehicle a "water-fuel car".[23] The company says it "cannot [reveal] the core part of this invention,” yet,[24] but it has disclosed that the system uses an onboard energy generator (a "membrane electrode assembly") to extract the hydrogen using a "mechanism which is similar to the method in which hydrogen is produced by a reaction of metal hydride and water".[25] The hydrogen is then used to generate energy to run the car. This has led to speculation that the metal hydride is consumed in the process and is the ultimate source of the car's energy, making the car a hydride-fuelled "hydrogen on demand" vehicle, rather than water-fuelled as claimed.[26][27][28] On the company's website the energy source is explained only with the words "Chemical reaction"[29]. The science and technology magazine Popular Mechanics has described Genepax's claims as "Rubbish."[30]

[edit] Thushara Priyamal Edirisinghe

Also in 2008, Sri Lankan news sources reported that Thushara Priyamal Edirisinghe claimed to drive a water-fuelled car about 300 kilometers[31] on three liters of water.[32][33] Like other alleged water-fuelled cars described above, energy for the car is supposedly produced by splitting water into hydrogen and oxygen using electrolysis, and then burning the gases in the engine. Thushara showed the technology to Prime Minister Ratnasiri Wickramanayaka, who "extended the Government’s full support to his efforts to introduce the water-powered car to the Sri Lankan market."[32]

Thushara was arrested a few months later on suspicion of investment fraud.[4]

[edit] Daniel Dingel

Daniel Dingel, a Filipino inventor, has been claiming since 1969 to have developed technology allowing water to be used as fuel. In 2000, Dingel entered into a business partnership with Formosa Plastics Group to further develop the technology. In 2008, Formosa Plastics successfully sued Dingel for fraud, with the 82-year-old Dingel being sentenced to 20 years imprisonment.[3]

[edit] Hydrogen as a supplement

In addition to claims of cars that run exclusively on water, there have also been claims that burning hydrogen or oxyhydrogen in addition to petrol or diesel fuel increases mileage. Around 1970, Yull Brown developed technology which allegedly allows cars to burn fuel more efficiently while improving emissions. In Brown's design, a hydrogen oxygen mixture (so-called "Brown's Gas") is generated by the electrolysis of water, and then fed into the engine through the air intake system. Whether the system actually improves emissions or fuel efficiency is debated.[34] Similarly, Hydrogen Technology Applications claims to be able increase fuel efficiency by bubbling "Aquyen" into the fuel tank.

A common fallacy found in connection with this type of modification is the mistaken assumption that cars generate excess electricity via their alternators that normally goes to waste and therefore is available for electrolysis. The amount of force required to turn an alternator or generator is directly proportional to the electrical resistance of the circuits it is supplying. If an electrolysis unit is added to a car, the amperage it draws from the car's electrical system will make the alternator harder to turn, which will put additional drag on the engine. As a result more fuel will be required to maintain the same rotational speed (RPM.)

A number of websites exist promoting the use of oxyhydrogen (often called "HHO"), selling plans for do-it-yourself electrolysers or entire kits with the promise of large improvements in fuel efficiency. According to a spokesman for the American Automobile Association, "All of these devices look like they could probably work for you, but let me tell you they don't."[35]

[edit] Gasoline pill and related additives

Related to the water-fuelled car hoax are claims that additives, often a pill, convert the water into usable fuel, similar to a carbide lamp, in which a high-energy additive produces the combustible fuel. This "gasoline pill" has been allegedly demonstrated on a full-sized vehicle, as reported in 1980 in Mother Earth News. Once again, water itself cannot contribute any energy to the process, the additive or the pill is the fuel.

[edit] Hydrogen on demand technologies

A hydrogen on demand vehicle uses some kind of chemical reaction to produce hydrogen from water. The hydrogen is then burned in an internal combustion engine or used in a fuel cell to generate electricity which powers the vehicle. While these may seem at first sight to be 'water-fuelled cars', they actually take their energy from the chemical that reacts with water, and vehicles of this type are not precluded by the laws of nature. Aluminium, magnesium, and sodium borohydride are substances that react with water to generate hydrogen, and all have been used in hydrogen on demand prototypes. Eventually, the chemical runs out and has to be replenished.[36][37][38] In all cases the energy required to produce such compounds exceeds the energy obtained from their reaction with water.[39]

One example of a hydrogen on demand device, created by scientists from the University of Minnesota and the Weizmann Institute of Science, uses boron to generate hydrogen from water. An article in New Scientist in July 2006 described the power source under the headline "A fuel tank full of water,"[39] and they quote Abu-Hamed as saying:

The aim is to produce the hydrogen on-board at a rate matching the demand of the car engine. We want to use the boron to save transporting and storing the hydrogen.

A vehicle powered by the device would take on water and boron instead of petrol, and generate boron trioxide. The chemical reactions describing the energy generation are:

4B + 6H2O → 2B2O3 + 6H2 [Hydrogen Generation Step]
6H2 + 3O2 → 6H2O [Combustion step]

The balanced chemical equation representing the overall process (hydrogen generation and combustion) is:

4B + 3O2 → 2 B2O3

As shown above, boron trioxide is the only net byproduct, and it could be removed from the car and turned back into boron and reused. Electricity input is required to complete this process which Al-Hamed suggests could come from solar panels. [39]

[edit] In popular culture

"Like Water for Octane", an episode of The Lone Gunmen (TV series),[40] is based on a "water-powered" car that character Melvin Frohike saw with his own eyes back in 1962.[41]

The Water Engine, a David Mamet play, made into a television film in 1994, tells the story of Charles Lang inventing an engine that runs using water for fuel. The plot centers on the many obstacles the inventor must overcome to patent his device.[42]

In "That '70s Show", Steven Hyde repeatedly makes reference to a "Car that runs on water" while in "The Circle."
