Four ULOG Ovens and a Solar Drier

Book "Four ULOG Ovens and a Solar Drier"

Use and Construction

Medicinal plants in an hospital are useless, maybe even dangerous, if not well dried and preserved. Therefore one day I met an engineer in Switzerland with the name Ulrich Oehler, that created "ULOG". Ulrich dedicated his whole life in using solar energy to save the environment ; we got his copyrights to spread his construction plans all over the world to save energy and to use the sunshine in preserving our medicinal plants!
