Germany’s Manfred Stefener has designed a new fuel cell that, as he puts it, “takes normal natural gas from the grid, and produces electricity, which covers about 40 to 60 per cent of the total electricity demand of a typical European home and it covers also like the full warm water demand of these homes.” The invention is up for a major European invention award and proves once again that innovation may be the only sustainable solution to the world’s environmental issues.
