“Hydrogen power engineering — is energy of the future”, efforts are being undertaken in the US, Europe and Russia to implement the above postulate. We have tried to calculate the quantity of hydrogen needed to transfer to it all transport of big cities, i.e. the quantity that will be required to replace engine fuels. All calculations were based on maximum coefficients of efficiency and the most optimistic figures. The conclusions made from the obtained figures seem interesting not only for scientists but also for general public: thoughtless implementation of hydrogen programs might require much more significant quantities of mineral weath than it does at present and result in disastrous deterioration of environment.
In hydrogen power engineering, hydrogen is the main vehicle for power transfer. Hydrogen is just the power carrier, but not its source. Energy is required in the course of getting hydrogen, the methods for getting hydrogen are not that numerous: chemical conversion of organic matter (combustible minerals, biomass); water electrolysis; thermal water disintegration, including that by nuclear energy.
To replace all engine fuels in the world (2,200 million tons, out of which 60 million tons are consumed in Russia), 679 million tons of hydrogen should be produced, that is the required amount is almost four times less as hydrogen is a more power-consuming fuel. If hydrogen is obtained through water electrolysis to which all adherents of hydrogen power engineering are standing up for, than 29,700 billion kilowatt-hours of electricity will be required for this purpose. However, all electric power stations of the world taken together produce only 15,500 billion kilowatt-hours! Therefore, to transfer motor transport to hydrogen, it will be needed to increase global power generation by 3 times (current ordinary consumers are still in place)!

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
