'''►► http://Magnet4Power.Net - ''' Products That Show How to Make Free Energy With a Magnet Motor - There are a lot of kits on the market that advertise to show you how to make free energy with a magnet motor. In physics, the law of conservation of energy tells us that energy can be neither created nor destroyed, only changed from one state to another. Here's a short look at magnet motors and the idea of free energy. A motor is a device that creates movement or action from some source of potential energy. It's a device that transforms energy. Magnetic motors are thought to create kinetic energy from the force of repulsion or attraction between the poles of magnets, with no external input. The repulsive and attractive forces that exist between the poles of separate magnets is somewhat analogous to spring. While kinetic energy may be produced when spring is released, it must first be compressed or stretched which requires in initial input of energy from an outside source. As the spring moves past equilibrium, the restoring force generated by the material, acts in the opposite direction thereby creating a net energy value of zero. The same is true of magnets. While two magnets may attract or repel, there must be a restoring force that replaces their position to the original starting point for them to once again generate a kinetic energy. Kits that promote free generation of energy generally rely on an alignment of the magnets in a way that is supposed to create a continual attraction or repulsion between poles. However, the effect of neighboring magnetic fields has still be shown to cancel and result in a zero sum energy production. Until a monopole is discovered that only attracts or repels, there will necessarily be a cancellation within the fields of magnets. An alternative method could be to utilize and existing force, such as gravity, against which the magnetic force could act. In this way the analogous spring could be continually reloaded. This then comes down to another question of alignment and friction within the given machine. Is it true? Does a motor built with magnets as its motive force act as an energy supply? Science generally says no, but there have been historical accounts of scientific notions going through upheaval. If a person is curious and interested in seeing how things work for themselves, try out one of the kits that show you how to make free energy with a magnet motor, and decide for yourself. Find out how you can make free energy. With the use of a magnet motor you will be able to supply your home with energy. Paying less on bills each month!

BY STEVEN SPARKMAN Here’s your latest update in “Robot takeover of Earth” news. Two robots are getting blog chatter this week for inching closer to mimicking living organisms -- one step at a time. First, the Nagoya Institute of Technology in Japan developed this ramblin’ man, BlueBiped. It’s a walking robot which mimics the human gait, and has no motors or electricity. It takes a small downhill grade to keep it going, and in tests it’s walked for 13 hours -- more than nine miles -- with no external power source. Video: DigInfo It works entirely through the potential energy of a downhill slope, making use of its momentum with carefully articulated joints. A writer for Popular Science praises the BlueBiped for its simplicity. “This type of forward falling motion is not exactly a new concept -- when I was your age, I had a Slinky, too -- but it’s an interesting reminder that robotic technology doesn’t necessarily need tons of servos and articulated limbs to accomplish a complex task.” The researchers tout their robots’ environmental friendliness, since it uses no fuel to move around. A writer for Wired UK explains some of their big plans for the bot. “There are two big ideas on the horizon: one is to transform the BlueBiped into some kind of exoskeleton to help people who have trouble walking. Another idea is to make the robot help out with sports equipment. Could be handy on the golf range, as long as it's all downhill.” Another robot getting attention this week -- how about a robot that eats living organisms? Two new prototypes destined for sci-fi horror are designed to mimic the venus fly trap and its lure-and-trap method of fly catching. Scientists in Maine created their carnivorous bot out of materials that mimic muscle fibers. Discovery News explains. “Touching the trigger hairs activates a solid-state relay and a small dynamic voltage generator causes the lobes to close quickly. The robot actually works. To test it, [the researcher] flicked the trigger hairs several times with a long stick and … the small Venus flytrap robot ensnared it. … he said the robot also successfully closed around a hapless fly.” A team in Korea were able to build the same sort of robot using shape memory materials. But neither of these fly traps actually digests the bug. But what do you know -- that technology also already exists. New Scientist spoke to a researcher at Bristol Robotics Lab, whose fly-digesting machine seems destined to join the fly traps. “Ecobot uses bacteria to break down a fly's exoskeleton in a reaction that liberates electrons into a circuit, generating electricity. But without a way to catch prey, the researchers either manually feed Ecobot with dead flies or use an ultraviolet bug lure -- like those used in restaurants. … ‘We'd be happy to talk to these groups about their flytraps.’” It’s a match made in heaven.

Varma designed ultra modern and high efficiency turbines which can use gas, steam or fuels as feed to produce electricity or mechanical work for wide range of usages and applications in industries or at work sites. Varma turbine engines can be used in all types of vehicles. These turbines can also be used in aircraft, ships, battle tanks, dredgers, mining equipment, earth moving machines etc, Salient features of Varma Turbines. 1. Varma turbines are simple in design, easy to manufacture, easy to operate and maintain. 2. Varma turbines are less expensive. 3. Varma turbines have a great power to weight ratio, compared to present turbines. 4. Varma turbines will have low maintenance costs. 5. Varma turbines will have 95% efficiency, the highest compared to any present turbines. 6. Varma turbine parts will be less prone to rust, erosion, wear and tear. 7. Varma turbines will arrest all leakages of steam, gas and water in respective turbines. 8. Varma water turbines can convert the whole potential energy in every drop of water, acquired by virtue of its position, into kinetic energy and further into electricity 9. Varma turbines will have no blades, either fixed or rotary, the complex structures of present turbines. 10. Varma turbines have common design to use gas, steam or water’s potential energy as feed to generate electricity or mechanical work. 11. Varma turbines will have low noise and no vibrations because the balance of the rotating sphere and shaft is perfect. 12. The base of the turbine will be more compared to its steam intake chambers. It gives more stability to turbine. 13. Varma turbine will face less thermal and corrosion fatigue, less stress, cracking and misalignment. Basic conceptual design of Varma Turbines - There are four types of varma turbines 1. Varma steam turbines 2. Varma gas turbines 3. Varma water turbines 4. Varma Turbine engines.

The Turgo turbine is an impulse type turbine; water does not change pressure as it moves through the turbine blades. The water's potential energy is converted to kinetic energy with a nozzle. The high speed water jet is then directed on the turbine blades which deflect and reverse the flow. The resulting impulse spins the turbine runner, imparting energy to the turbine shaft. Water exits with very little energy. Turgo runners may have an efficiency of over 90%. A Turgo runner looks like a Pelton runner split in half. For the same power, the Turgo runner is one half the diameter of the Pelton runner, and so twice the specific speed. The Turgo can handle a greater water flow than the Pelton because exiting water doesn't interfere with adjacent buckets.
