Increase Productivity

Energy spectrum of gas particles in plasma is broad, ranging from fractions to 10s of electron volts. Proportion of particles with required energetic parameters, participating in cubic carbon c-C synthesis, is small. External energy deposition can transfer an inert carbon atom to active state and change its electronic configuration. Binding energy of c-C atom depends on energy sources interaction. In this work, the calculations found the binding energy value that was compared with value of energy of the bond between the carbon atoms in ethane. The advisability of external source, activated carbon atoms generator, is marked. It has been established that by adding accelerated carbon atoms with energy of 9,687 eV into reactor it is possible to increase productivity of films, coatings and bulk crystals growth.

Energy efficiency is vital for uninterrupted long-term operation of wireless underground communication nodes in the field of decision agriculture. In this paper, energy harvesting and wireless power transfer techniques are discussed with applications in underground wireless communications (UWC). Various external wireless power transfer techniques are explored. Moreover, key energy harvesting technologies are presented that utilize available energy sources in the field such as vibration, solar, and wind. In this regard, the Electromagnetic (EM)- and Magnetic Induction (MI)-based approaches are explained. Furthermore, the vibration-based energy harvesting models are reviewed as well. These energy harvesting approaches lead to design of an efficient wireless underground communication system to power underground nodes for prolonged field operation in decision agriculture.

Improve Energy Efficiency

Modern agriculture is dependent on external energy sources. Non-renewable energy sources play a dominant role, which contributes to greenhouse gas emissions and, as a consequence, to environmental degradation. Therefore, it becomes obvious to strive to improve energy efficiency and change the structure of its sources. One of the main research goals was to determine the economic and energy efficiency of agriculture in EU countries and assess its energy consumption by analysing energy consumption per employee or 1 ha of utilized agricultural area. The work analyses changes in energy consumption in agriculture of the European Union and its members. Eurostat data was used for the analysis.
