The main part of the exhibition comprises large, real size exhibits that work with the use of biofuels and are constructed by Miltos Choumerianos family. Two working maquettes of the old olive mill and the water cycle contribute to the introduction and understanding relevant educational subjects. Through the educational programmes and with the use of small working models and experiments every year all the renovations at the field of energy production are presented. The selection is made after attending international exhibitions and the cooperation with well-known companies, which specialize in the design and production of educational models for schools and other educational sectors. Some of them are: the steam engine for electricity production using solid biomass, the bioethanol electricity producing system, the electricity production system with salt water, geothermal energy, and the hydro turbine but also the electrolysis unit for hydrogen production for the use in hydrogen car models.
