Read moreThe hands of a clock tell the whole story. Technical factors place limits on the precision of the reading. For physicists, so-called shot noise also imposes such a limit. It occurs for example when electric current has to overcome a barrier. At present, all precision measurements work close to this limit. Physicists from Heidelberg University have now demonstrated that this limit can be surpassed by drawing on concepts from quantum mechanics.

Read moreLower CO2 emissions demand more renewable energy in the energy system. This calls for new solutions that take account of the considerable variations in the amount of wind energy, hydropower, solar energy etc. One of the solutions is a distributed energy system. Here it must be possible to store surplus energy locally using, for example, local SPEC electrolytic cells. The foundation for this technology is being developed by the CASE research project.
