More on the initiative
Who, what and why?
The initiative was started in the begin of 2021 by founder Luc Ruijters. He's an independent product developer who, after analyzing the sustainable electricity market, found that the use of geothermal energy was not reaching its full potential.
So he started searching for and developing solutions, one of those solutions is the geothermal electricity generator, or GeoTeg for short.
After a successful 'proof of concept', and the filling of the patent, the time has come to invite capital and specific knowhow to accelerate this initiative and to make it a success for all stakeholders involved!
More on the invention / the generator
What, how, the benefits and the future.
A geothermal electricity generator is a generator that produces electricity harnessing the earths heat. Commonly, boiling water is brought up from great depths in the earth and its steam will power a turbine which produces electricity. In Iceland for example this process is simpler because of its natural geysers.
But not every country is Iceland and drilling at great depths is extremely costly and not without difficulties and risks.
Geoteg is created to harness the abundant energy of the earth, but more in an universal, local and low capital manner. GeoTeg also wanted to deliver a solution that was beneficial on many levels, not only looking at the power output, but also on recyclability, visual pollution, adaptability, etc. etc.
The main components of the generator are:
1) an underground heat absorber to transport the warmth of the earth to a heat pipe,
2) a specially designed heat pipe to transport this thermal energy towards the surface and
3) Thermoelectrical generators (TEG’s) with heat-sinks that use the Seebeck principle to convert this thermal energy to electricity using the temperature difference between the temperature underground and the temperature on the surface.
These are the main components of the ‘winter module’. The summer module will use this effect in reverse using a looped heat pipe system. The integration of both models into one ‘all season’ model is in the early stages of development.
The scale of these geothermal electric generators is relative small, a approximately 2,5 meters in length underground, 20 centimetre in length above ground and 20 centimetres in width. Because of the relative constant temperature at that depth, and the minimal above ground exposure, this is the optimal minimum length. But the generator remains easily scalable to almost every situation.
