Three different applications of Transparent Insulation Materials (TIM) in the temperature range of 70 degree C to 190 degree C have been investigated: A hot air sterilizer in which medical instruments can be sterilized at temperatures up to 190 degree C has been developed and tested. It is posible to improve flat plate collectors considerably, if a TIM is used as the collector cover. At operating temperatures of about 100 degree C the efficiencies of improved flat plate collectors are comparable with those of evacuated tubular collectors. Also experiments with a small, cube-shaped, transparently insulated storage system have been made. Currently a shallow pond of 20 cm water depth and an aperture area of 5 square meter is being investigated.
