Unravelling Coronal Mass Ejections from Our Solar System’s Origin

Young stars ejecting plasma could give us clues into the Sun’s past Kyoto, Japan — Down here on Earth we don’t usually notice, but the Sun is frequently ejecting huge masses of plasma into space. These are called coronal mass ejections (CMEs). They often occur together with sudden brightenings called flares, and sometimes extend far enough to disturb Earth’s magnetosphere, generating space weather phenomena including auroras or geomagnetic storms, and even damaging power grids on occasion. Scientists believe that when…

Wärmepumpe

An der Hochschule für Technik und Wirtschaft des Saarlandes (HTW
Saar) wurde nun ein System entwickelt, dass die Möglichkeiten erdgedeckter Flüssiggas-tanks optimal aus nutzt und so eine substanzielle Energie-und Kosteneinsparung generiert. Die entscheidende Innovation besteht darin, dass flüssiggas betriebene Blockheizkraftwerk (BHKW) mit einer Wärmepumpe zu koppeln, wobei der Gastank außer zur Speicherung des Flüssiggases gleichzeitig
als Erdwärmekollektor und Verdampfer für die Wärmepumpe genutzt wird. Dies ist nur bei einem erdgedeckten Tank sinnvoll möglich.
Das Flüssiggas dient im laufenden Betrieb gleichzeitig als Kraftstoff und als Kältemittel. Die erfindungsgemäße Anlage trägt auf diese Weise dazu bei, Betriebskosten zu reduzieren und die Energieeffizienz des Systems zu steigern. Da die verwendeten Komponenten bis auf wenige Bauteile mit denen eines herkömmlichen flüssiggasbetriebenen BHKW übereinstimmen, kann auf einfache Weise und ohne die Anschaffung separater Wärmekollektoren ein deutliches Einsparpotenzial nutzbar gemacht werden. Modellrechnungen
ergeben eine Reduktion des Kraftstoffverbrauchs von bis zu 40%.
Die Optimierung des gesamten Systems im Hinblick auf die verschieden Betriebsparameter ist Gegenstand einer aktuellen Prototypenstudie.
