As our TEC-G technology becomes more visible, we are increasingly receiving reviews and comments generated by generic AI systems such as ChatGPT, Claude, or Gemini. At first glance, these AI-based assessments seem plausible—but when it comes to innovative technologies, they are often way off the mark.
Economical
HEIONTEC power applications do not require a conventional energy source and therefore do not incur any running costs. Once installed, these systems produce electricity continuously at room temperature - free of charge and permanently.
Sustainable
HEIONTEC dispenses with fossil materials in production and operation. Short distances and a high recycling rate make the technology a forward-looking solution for more sustainable energy generation.
Independent
HEIONTEC cells only require ambient heat to generate electricity. This enables a self-sufficient supply for devices that previously relied on batteries or cables.
The intelligent use of thermochemical reactions for self-sufficient energy supply represents a real technological leap forward.
Prof. Dr. Jens Bockstette
Professor of Energy Conversion and Storage, Düsseldorf University of Applied Sciences
As an engineer with many years of experience in electronics development, I find HEIONTEC's technology extremely exciting—an innovative approach with great potential for sustainable energy generation and new applications in the electronics sector.
