New generator creates electricity directly from heat

New generator creates electricity directly from heat | ESI Electrical Group | Scoop.it

A new type of thermionic generator that turns heat or light into electrical energy has been developed by researchers in Germany and the US. The new design overcomes the "space-charge problem" that has plagued previous attempts at developing practical devices. The device is about four times more efficient than previous generators and the new technology could find use in a range of applications including solar power and the harvesting of waste heat.

 

Thermionic generators convert heat or light into an electric current by using the temperature difference between two metallic plates that are separated by a vacuum. The "hot" plate is heated either by incident light or thermal conduction and this causes electrons to evaporate from its surface. These electrons then condense on the surface of the cold plate. This creates a charge difference between the two plates, which can drive a usable electric current.

 

Because they convert heat or light directly into electrical energy, thermionic generators have considerable potential for practical applications. If used in coal-fired power stations, for example, thermionic converters would, in principle, be more efficient than steam turbines. Thermionic generators could also be applied to a variety of lower-temperature applications, such as the collection of solar energy or the recycling of waste heat in car engines.

 

Neil Fox of the University of Bristol in the UK points out that the new generator has similarities to a planar triode design tested at the Massachusetts Institute of Technology (MIT) in the late 1950s. This previous design had suffered from energy loses caused by electron–electron collisions and scattering. "[Mannhart and colleagues] have come up with a rather neat vertical triode structure that seeks to improve on the MIT device, by incorporating beam collimating concepts similar to those used in particle accelerators," explains Fox. "The data presented...show that this magnetic triode is a significant improvement over a closed-spaced diode, but suggests that electron–electron collisions and scattering losses to the gate are still present."

 

The team is now working to increase the efficiency of its generator design in two ways. First, it is building high-performance converters from existing semiconductor technologies. Second, it is optimizing its electrodes through the use of new materials, especially oxides, and nanotechnology.

 

The work is described in the Journal of Renewable and Sustainable Energy.

Difference From AC and DC Electric Motors

Difference From AC and DC Electric Motors | ESI Electrical Group | Scoop.it

AC electric motors operate by applying alternating current (AC) power to the electric motor. The main parts of AC electric motors are the stator and rotor. AC electric motors stator consist of coils that are supplied with alternating current power and produce a rotating magnetic field. AC electric motors rotor will rotate inside the electric motor coils and the output shaft produces torque via the rotating magnetic field.

This article explains the risks and consequences of electrical fires that occur in the industry if safet is not carried properly.  It is very important to have a safety conscience so that accidents do not occur.   

OHS Electrical's curator insight, July 21, 2015 9:22 PM

The idea of hiring a professional to check any electrical equipment may be costly; however, what is important is preventing fires and/ or casualties.  When on work experience, the company employed a qualified person to check all equipment.  He had an unbiased view and often found hazards more readily than those working in the company.  It is a wise idea to hire a professional to check all electrical equipment.
