NASA Langley Research Center has developed a novel negative dielectric constant material based on ion conducting materials. A negative dielectric constant material is an essential key for creating metamaterials, or artificial negative index materials (NIMs). NIMs have generated great attention due to their unique and exotic electromagnetic properties, and could be used for unique optical and microwave applications, including new methods of electromagnetic cloaking and extremely low loss communications.

Benefits

* Controllable resonance frequencies from radio to optical frequency
* Effective negative dielectric constant and resonance frequency can be controlled by dopant type, temperature, concentration and effective mass of dopant
* Can be used to create novel negative dielectric constant materials and negative index materials
* Molecular level homogenous ...

1.) NATURE OF TECHNOLOGY/PRODUCT:The Nigam’s Mechanism acts as an extension to the current state-of-the-art motors used in electric vehicles. The Nigam’s Mechanism consists of an extended pair of pipes connected to the inside edges of tires which are further connected to a strong bar magnet with a steep gradient between its poles and mid-point. This bar magnet is enclosed in a special multi-layered crossed (so as to produce D.C. current) spherical copper coil to increase the net amount of flux changes taking place due to the rotating magnet thereby increasing the efficiency of the product. The copper coil is connected to the battery via a reversed-biased Zener Diode attached in series.

A new linear solar collector has been developed and patented that promises to be a less expensive replacement for parabolic trough collectors. Parabolic trough collectors suffer from the difficulty of maintaining mirror orientation for a very large mirror that can be subjected to significant winds. This new patented design uses a fixed mirror and instead moves a small absorber to track reflected light off of the fixed mirror. This allows for significant cost savings in structural components, as well as reduced maintenance cost due to broken mirrors.

The collector is comprised of two slightly curved stationary mirrors slightly curved into a shallow trough shape, oriented in an east-west direction, with the mirrors meeting at the middle of that trough.

Restaurants produce a large amount of edible waste oil. Some owners would pour it into the river which causes pollution in the soil and water.

Oil Bubble is a cleaning liquid maker that recycles and reuses waste oil. Making cleaning liquid by pouring the waste oil into Oil Bubble and adding water, natural foaming agent, and thickener. It can be used to clean the environment as well as wash hands. The peel can also be thrown into the machine to be made into essence, replacing the chemical essence. Using it, owners can reduce the cost of waste oil recycling and purchase of cleaning liquid, and pass on the environmental thinking to ...

Oil spillage in sea, ocean is very common and creates serious environmental problems. There are a number of ways available to tackle this problem. We propose a new method which is very easy, chemical free and clean to solve this problem of oil spills. We attach strong neodymium magnets at the outer side of a ship's structure preferably at the draft or at water level. Then spray very fine magnetite particles over the oil surface as much as possible  As these are very fine and lightweight, these tiny particles float on the oil surface and stick to oil. Then move the boat in oil spill affected area. What is seen is that most of the oil starts getting attracted ...

We live in a world that needs more electric power. This increase in power must be produced by a source that produces no carbon dioxide. This new energy must also be present in large quantities and must be able to be extracted cheaply. There are many sources of thermal energy in which there is only a small temperature difference between the source and the sink. These sources include geothermal energy, ocean thermal energy, many solar sources, waste heat from engines, waste heat from industrial processes, and differentials between atmospheric temperature and ground temperature. These sources have enormous amounts of thermal energy. However, since the efficiency of tuning thermal energy into mechanical energy is based on the temperature differences, these ...

Our motor concept is both novel and sustainable. It requires no complicated windings or Rare Earth magnets. The idea utilizes the Lorentz Force: In physics (particularly in electromagnetism) the Lorentz force is the combination of electric and magnetic force on a point charge due to electromagnetic fields. A particle of charge q moving with velocity v in the presence of an electric field E and a magnetic field B experiences a force
F = q E + q v × B
(in SI units[1][2]). Variations on this basic formula describe the magnetic force on a current-carrying wire (sometimes called Laplace force), the electromotive force in a wire loop moving through a magnetic field (an aspect of Faraday's law of ...

In cases of natural disasters and lack of resources there is a huge gap in communication. It generates problems like:
- No power or electricity to charge your phone.
- No internet connections.
- Scarcity of food.
Peltiier charger is designed by reversing the effect of peltier plate to generate voltage and charge your phones which makes communication easy when you are stuck in a natural disaster or villages with no ...

The Spiral Magnetic Motor (SMM) is novel and unique since it has been proven to accelerate a permanent magnet rotor through 90% of its cycle with only permanent magnets, thus potentially providing a clean, inexhaustible source of constant torque for use as a motor or generator. The principle of applying an inhomogeneous, anisotropic magnetic field gradient force Fz = μ cos φ dB/dz, with permanent magnets is well-known in physics, e.g., Stern-Gerlach experiment, which exploits the interaction of a magnetic moment with the aligned electron spins of magnetic domains. In our case, this principle is applied to dB/dθ in polar coordinates, where the force Fθ depends equally on the magnetic moment, the cosine of the angle between the magnetic ...

Phononic Vibes introduces a new disruptive technology with unprecedented performances in the vibration and noise control and isolation, with a circular economy approach.

It originated from the research activity at Politecnico di Milano and Massachusetts Institute of Technology of its founders in the field of meta-materials, to achieve and engineer novel and unmatched properties. Thanks to the versatility of its products, which are protected through the pending patents of the fundamental technology, Phononic Vibes guarantees isolation performances much greater than the products nowadays on the market, in the infrastructure and industrial sectors, introducing a revolution in these fields.

The aim of the project is the development, production and selling of the first vibration and noise isolation products (so-called phononic ...
