Sustainable energy used for Alpine caviar

Описание

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, SF/swissinfo.ch 21.12.2009)
