Thermal energy harvester based on SensEver Alfa-S developed by TEGnology ApS can turn temperature differences into electrical energy.
The working principle of SensEver Alfa-S is thermoelectric power generation (TEGs). TEGs convert temperature differences into electrical energy via the Seebeck Effect. Thus, wherever a temperature difference occurs, there is potential for thermal energy harvesting. Thermal energy harvesting devices replace batteries and cables.
Benefits:
MISO thermal energy harvesters are very reliable, have a long lifetime and do not require any maintenance, therefore cutting down the maintenance costs. They are also emissions-free.
Characteristics:
For the aforementioned reasons, a thermal energy harvester is developed the MISO project, which aims at collecting environmental data in n hard-to-reach areas, where energy supply is challenging. Here, the temperature differences between soil and air in these areas serve as a source of energy with the use of the thermal energy harvester.
The necessary temperature difference is reached by installing a metallic rod in the ground and a heat sink above the ground. The metallic rod serves as a heat conductor that establishes the soil temperature on one side of the TEG. Heatsink in the air reaches the air temperature and imposes this temperature on the other side of the TEG. With state-of-the-art TEGs and power management units, usable power can be generated under a temperature of 8 Degree Celsius.
