Thermoelectric Generators. A New Disruptive Technology

Posted by POWERSPOTResponsive · Innovative Products and Technologies · Spain

Summary of the technology

Power generation occurs as a result of the temperature differential between the base and the top of the generator, without incorporating moving parts and therefore without breakdowns or maintenance.

New and innovative aspects

  1. J. T. Seebeck, in 1821, discovered that a compass needle would be deflected by a closed loop formed by two different metals joined in two places, with a temperature difference between the junctions.
  2. This was because the metals responded to the temperature difference in different ways, creating a current loop and a magnetic field.
  3. Seebeck did not recognize there was an electric current involved, so he called the phenomenon the thermomagnetic effect.
  4. Danish physicist Hans Christian Ørsted rectified the mistake and coined the term "thermoelectricity".
  5. The Seebeck effect is the conversion of temperature differences directly into electricity.
  6. A thermoelectric couple is a device consisting of two dissimilar semiconductors that contact each other at one or more points.
  7. Voltage is produced when the temperature of one of the contact points differs from the temperature of another, causing the electrons to move away from the hot end toward the cold end. When the electrons go from the hot side to the cold side this causes an electrical current.
  8. Multiple thermoelectric couples can be connected in series in order to compose a thermopile, also known as Thermoelectric module, or Thermoelectric generator (TEG).

Main advantages of its use

Powerspot products are low-power portable electric generators fed by any type of combustible fuel (biomass, wood, gas, etc.). Free from any type of maintenance or break-down, they have no moving parts. To start generating electricity only a small source of heat and a refrigeration method (water or air) are necessary.

They are designed for charging and illumination in hostile environments, populated areas or isolated settlements. They provide the perfect solution for Outdoors and developing countries.
