Sustainable caviar Renewable energy drives alpine sturgeon and fruit farm

The 'Tropenhaus' or Tropical House in Frutigen is expected to prove a major attraction for visitors to the Bernese Alps this Christmas, offering a tropical experience for people seeking refuge from the winter chill. The project uses sustainable energy for growing exotic fruit and breeding sturgeon, which will soon produce caviar. (Julie Hunt, swissinfo.ch/SF)
