By its nature, the Plant-MFC can become 10 times as efficient as conventional bio-electricity systems (like biogas and bio-ethanol production), because no energy has to be invested to generate electricity. Furthermore, the systems’ concept is principally clean, renewable and sustainable. The technology might be implemented in several ways, ranging from local small scale electricity providers to large scale electricity wetlands & islands, high-tech electricity & food supplying greenhouses and novel bio-refineries. This way, affordable electricity can be produced everywhere where plants can grow. This is not limited to Europe. It offers opportunities for developing countries and remote regions as well. Plant-MFCs can be integrated in landscapes invisibly which makes this technology socially highly acceptable.
