BioSampo Training and Research Centre in Finland has focused to train renewable energy professionals. We have developed a practical learning environment (it's like a workshop/lab for bio and solar and wind energy production) for training and demonstration purpose. In the lab of BioSampo you will found installed many appliances related to digestion, estherification, gasification, pyrolysis, combustion engines, steam machines, heating, cooling, electricity production and distribution etc. But we are missing a water purification appliance. One of BioSampo's main principle is to take advantage of by products and waste heat and solar of course.
