Steel pistons for more efficient diesel engines

With a new cooling concept, an automotive industry supplier is expanding the range of applications for steel pistons in diesel engines. The Stuttgart-based company is testing a liquid alloy comprising sodium and potassium, which dissipates heat from the particularly thermally loaded piston head. This innovative steel piston concept is designed to enable even further increases in the specific power of car diesel engines. In the case of long-running engines for industrial applications and commercial vehicles, the component and engine oil load is significantly reduced while the expected service life and oil change intervals are prolonged.  more...

The hotline in the grid

The electricity grid that has been used for decades reaches its limits when transporting increasing amounts of electricity over long distances. There are already limiting bottlenecks. One way to integrate more wind and solar power into the grid is provided by overhead lines with a higher maximum temperature. These can transport more electricity, enabling grid congestion to be avoided. One problem, though, is that metals expand more at high temperatures. As a result the line lengthens and sags more. However, special high-temperature conductors can provide a remedy here.  more...

Cooling with solar heat

The cooling or air conditioning of buildings with solar heat has a particular appeal because the heat demand and supply are usually consistent with each another. Cold stores in southern climates and many process refrigeration systems also require considerable energy when the sun shines intensely. The use of solar cooling systems instead of electric chillers also eases the grid, particularly at peak load times.  more...

Efficiently heating & cooling non-residential buildings

The use of environmental energy to cool or, in combination with heat pumps, to heat non-residential buildings via thermo-active building systems (TABS) has established itself in recent years. The objective of such building and system concepts is not only to consume as little energy as possible in quantitative terms (low energy), but also to achieve the most optimal energy conversion in thermodynamic terms that takes the quality of the energy used into account (low exergy, „LowEx“).  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...
