"This plan is serious," insisted Zoneeveld. "All kinds of big companies have now stepped in, various municipalities and investors are interested."
The project is provisionally named "Die Berg Komt Er", or "The Mountain Comes", presumably in a reference to the phrase, "bring the mountain to Mohammed".
A working group has already been set up to look further at the feasibility of the project, which is projected to cost anywhere between £40bn and £270bn and take up to 30 years to build.
The basic plan is to construct a skeleton which would then be covered in organic material using technology which already exists to create a truly living mountain - one which, perhaps even more unbelievably, could be located on land or out at sea.
Even more surprising, perhaps, the hollow mountain could become a city in itself, with houses, shops, arenas and even roads and railways within.
And while the mountain will eventually be used for power production, housing and water supply, Zonneveld insists that it is the love of sport which will make it happen.
