Energy transformation

Energy transformation, also known as energy conversion, is the process of changing energy from one form to another. In physics, energy is a quantity that provides the capacity to perform work or provides heat. In addition to being convertible, according to the law of conservation of energy, energy is transferable to a different location or object, but it cannot be created or destroyed. The energy in many of its forms may be used in natural processes, or to provide some service to society such as heating, refrigeration, lighting or performing mechanical work to operate machines. For example ...

                                               

Airborne wind turbine

An airborne wind turbine is a design concept for a wind turbine with a rotor supported in the air without a tower, thus benefiting from more mechanical and aerodynamic options, the higher velocity and persistence of wind at high altitudes, while avoiding the expense of tower construction, or the need for slip rings or yaw mechanism. An electrical generator may be on the ground or airborne. Challenges include safely suspending and maintaining turbines hundreds of meters off the ground in high winds and storms, transferring the harvested and/or generated power back to earth, and interference ...

                                               

Allam power cycle

The Allam power cycle or Allam cycle is a process for converting fossil fuels into mechanical power, while capturing the generated carbon dioxide and water. It is an emission free natural gas fired power plant, where natural gas is used as fuel and instead of air uses pure oxygen eliminating emissions of nitrogen oxides; while a part of the output carbon dioxide is recirculated in the system, the excess carbon dioxide is transferred for sequestration or other industrial uses. The main inventor behind the process is English engineer Rodney John Allam.

                                               

Alternator

An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. For reasons of cost and simplicity, most alternators use a rotating magnetic field with a stationary armature. Occasionally, a linear alternator or a rotating armature with a stationary magnetic field is used. In principle, any AC electrical generator can be called an alternator, but usually the term refers to small rotating machines driven by automotive and other internal combustion engines. An alternator that uses a permanent magnet for its magnetic field is c ...

                                               

Anomalous photovoltaic effect

The anomalous photovoltaic effect, also called the bulk photovoltaic effect in certain cases, is a type of a photovoltaic effect which occurs in certain semiconductors and insulators. The "anomalous" refers to those cases where the photovoltage is larger than the band gap of the corresponding semiconductor. In some cases, the voltage may reach thousands of volts. Although the voltage is unusually high, the short-circuit current is unusually low. Overall, materials that exhibit the anomalous photovoltaic effect have very low power generation efficiencies, and are never used in practical pow ...

                                               

Aquanator

The Aquanator is a small-scale tidal-power device, a device which uses rows of hydrofoils to generate electricity from water currents. It was invented by Australian inventor Michael Perry.
