Sven Linow is a friendly person. He always speaks in a calm voice. This gives even more weight to the uncomfortable truths that the physicist states with crystal clarity. Soft soap would not do the matter justice either: it's all about climate protection (for him). As a professor of thermodynamics and environmental technology, Linow wants to teach "energy literacy": Energy literacy. Linow thinks and acts beyond the boundaries of his specialist field. He is involved in many different ways, including with "Scientists for Future". A conversation about our future energy supply, sufficiency and small disasters.
