Photos: Renewable energy devices in village Oreshak
( PHOTO: JULY 2007. VILLAGE ORESHAK, REGION VARNA, BULGARIA ) In Bulgaria people install solar collectors despite winter, when the energy usage is maximal and solar collectors efficiency is very low. An engineer from one of the companies in Varna, that make projects and assemble solar heating systems, has said, "during December, January, February, only some days you will have some heat from solar collectors". The speech was about vacuum pipe solar collectors, the most effective nowadays device to transform sunlight into heat energy. Ruins on the photo: in Bulgaria people often first finish the house and then reorganize the garden and the wall. |
