Nothing has changed since the Stone Age ... Prehistoric people harnessed the power of fire. Little has changed since then. The civilised world still relies on the principle of combustion. In the Stone Age people were environmently friendly - wood was burned: people used clean, renewable energy. Engines, jet propulsion and heating systems perform using the same principles of combustion as they did during the Stone Age. With one small difference: fossil fuels pollute the environment and are bio-destructible. The primitive times (in which crude oil and carbon have its roots) had been a mostly rough and inhospitable geological era. During thousands of years of evolution, nature gathered these substances beneath the earth's surface. Humankind needed less than one century to blow half of these harmful substances into the atmosphere. One litre of petrol pollutes 10 000 litres of air. The remaining sources of gas, petroleum and carbon will be used up, tanked, heated and burnt without thinking about unwanted effects. Due to these problems we are trying to find alternative substances we can use to live in harmony with our environment without abandoning the developments our society has achieved. One example is the production of biodegradable alternative fuel like Biodiesel. That's what we stand for: Bioenergie Mureck - SEEG Mureck - Nahwärme Mureck - Ökostrom Mureck - and many more organisations all over the world.
