Anomalies in temperature dependence (TD) for optical activity of water solutions for glucose, saccharose and dextran have been studied in temperature range of 2°C to 40°C. Abnormal fluctuations of specific rotatory power in solutions of sugars below 15°C have been discovered. Arrhenius approximation of TDs for chirality of solutions of sugars and a number of terpenes were applied to determine their activation energy to be in the range of 0.15 kJ/mol to 1.2 kJ/mol. These values were found to be identical to energies of free molecular rotation. It has been shown by comparative analysis of TDs for water physical properties and those of chirality of solutions of sugars and terpenes that the dynamics and kinetics of anomalies and fluctuations of chirality in water solutions of sugars are limited by abnormal thermodynamics of water. Reforming of water cluster structures has been associated with curving of TDs for chirality of sugars in temperature range of 20°C to 25°C. Interaction and incorporation of sugar molecules in clusters and supramolecular structures of water contribute to their stability and increase in lifetime. © 2016 Elsevier B.V. All rights reserved.

The discussion of introduction of separate PV solar systems in Russia is presented with the analysis of their current state and difficulties of their implementations. The study of potential growth is given with the evaluation of demand, needs, technological changes, equipment supply, legal environment and government backing. The workflow and specifics of separate PV systems production in Russia are also studied with proposed solutions to common problems. The general PV system calculation framework is presented with some examples. Calculations, charts and diagrams are also present. Source

The large power companies in many countries of the world put huge financial and scientific resources in development of high-temperature superconductivity technology for reduction of Joule losses. There is another, probably, more effective way to decrease losses in the power transmission electric lines: to develop adjustable resonant waveguide systems of electric power transmission on the increased frequency 1-100 KHZ which do not use an active conductance current in the closed circuit. The new physics of electric processes using not active, but a reactive unclosed current in openended line, will allow to solving three main problems of electric power industry:-Construction of long-distance transmission lines with low losses without use of technology of superconductivity;-Increase in transmission capacity;-Replacements of overhead lines on single-wire waveguide cable lines and decrease of copper consumption in a cable by 20-50 times. The innovative resonant electric power engineering requires government support for realization of pilot and demonstration projects and is looking for new Morgan who one hundred years ago has financed N.Tesla's works.

Development of solar power engineering must be based on original innovative Russian and world technologies. It is necessary to develop promising Russian technologies of manufacturing of photovoltaic cells and semiconductor materials: chlorine-free technology for obtaining solar silicon; matrix solar cell technology with an efficiency of 25–30% upon the conversion of concentrated solar, thermal, and laser radiation; encapsulation technology for high-voltage silicon solar modules with a voltage up to 1000 V and a service life up to 50 years; new methods of concentration of solar radiation with the balancing illumination of photovoltaic cells at 50–100-fold concentration; and solar power systems with round-the-clock production of electrical energy that do not require energy storage devices and reserve sources of energy. The advanced tendency in silicon power engineering is the use of high-temperature reactions in heterogeneous modular silicate solutions for long-term (over one year) production of heat and electricity in the autonomous mode. © Pleiades Publishing, Inc., 2015.

The paper suggests an energy model for the future world based on solar power engineering and new Russian energy technologies. Chlorine-free solar silicon technologies, stationary concentrators, solar mod- ules with service lives doubled up to 40 years, matrix solar elements with an efficiency factor of 20% at a con- centration of 5-500, and resonance waveguide methods for transmitting energy for solar energy systems are considered. © Allerton Press, Inc., 2012.
