There are some 30 solar collectors of various designs which use an insulating vacuum region to protect the absorber from heat losses. The designs include long Dewar-type tubes, single evacuated tubes containing an absorber, and flat plate-type collectors with a cover of evacuated tubes. To date, there are four evacuated tube collectors which have been tested, used in demonstration sites, and made available to the market on a limited basis. Recent developments in evacuated collectors include use of air as the heat transfer medium, use of CPC reflectors, and introduction of a heat pipe.
