Tropenhaus project enters final stages

Switzerland now has its own source of caviar. The first Swiss-bred sturgeon are now swimming around in the Bernese mountains, in tanks fed by warm water from an underground spring. The water is discharged in Frutigen from the longest tunnel in the Alps – the Lötschberg. The spring water will also be used to heat greenhouses growing tropical fruit: all part of the Tropenhaus project, now in its final construction phase. (SF/swissinfo)
