Highly efficient energy harvest via external rotating magnetic …
To achieve high photothermal efficiency, the direct absorption solar collectors (DASCs) was proposed by Minardi in the 1970s [7]. In DASCs, the light can be absorbed directly by working fluids and converted into heat. Compared with the traditional solar collectors, it has significantly higher photothermal conversion efficiency and lower …

Active Solar Heating
Solar liquid collectors are most appropriate for central heating. They are the same as those used in solar domestic water heating systems. Flat-plate collectors are the most common, but evacuated tube and concentrating collectors are also available. In the collector, a heat transfer or "working" fluid such as water, antifreeze (usually non ...
