Swift construction of pipelines

The laying of pipes, for example for heating networks, has previously been a labour intensive and time consuming occupation. With the newly developed “Pipe Express” method, a special tunnel boring machine drills through the ground at speeds of up to 1.2 metres per minute and conveys the soil directly to the surface instead of displacing it sideways. At the same time, the steel or concrete pipe is inserted into the horizontal borehole. In comparison with the open cut method, the process requires less than a fifth of the normal trench width and can also be used without lowering the groundwater level.  more...

Making machine tools work more efficiently

When machine tools process complex components, often only about 20 % of the energy deployed flows into the actual metal cutting processes. The main loads tend to be peripheral machine components, such as cooling systems or hydraulic drives. In the Maxiem project, scientists from the Technische Universtät Darmstadt and industrial partners are showing how this energy requirement can, in ideal cases, be more than halved.  more...

Solar thermal power plants

The annual solar irradiation on the earth provides more than 8,000 times the world’s energy requirements. Mathematically speaking, about 1 % of the surface area of the Sahara Desert is sufficient in order to meet the world’s electricity requirements with solar thermal power plants. A solar thermal power plant was already constructed close to Cairo at the beginning of the 20th century. Using parabolic mirrors, the power plant captured and concentrated solar energy and used it to heat oil for boiling water. This in turn was used to drive steam turbines and produce electricity.  more...

Electrically driven heat pumps

Electric heat pumps have become firmly established in the German heating market. In recent years they have gained an eight to ten per cent share of the market. Approximately every fourth new building is heated with a heat pump. Whereas until a few years ago ground source heat pumps were still sold the most, the sales figures have shifted in recent years in favour of air source heat pumps. Carefully planned, heat pump systems compare very economically with other heating systems.  more...

Schools plug into the sun

Photovoltaic systems in schools help save energy and enhance classroom teaching. They shape a school's image and indicate that energy supply is a future-focused subject. Grants are available to schools wanting to install photovoltaic panels.  more...

Schoolchildren are saving energy

At many schools they already exist: schoolchildren as energy detectives, energy managers or energy teams. They track down energy leaks, take the initiative, assume responsibility and ultimately know a great deal about saving energy. Their commitment is often also financially rewarding for their school.  more...
