摘要 |
The invention relates to a non-gaseous carrier medium, which is transformed into a gaseous carrier medium by means of thermal energy that is introduced such that the gaseous carrier medium rises to a predetermined height. The gaseous carrier medium is compressed. The compressed gaseous carrier medium is reconverted into a non-gaseous carrier medium at the predetermined height by means of a cooling circuit receiving heat of the carrier medium. The heat received by the cooling circuit is subsequently returned at any arbitrary location in order to be used to heat the carrier medium. |
