energiaátviv

energiaátviv is a term found in Hungarian technical literature that denotes the process by which energy is transferred from a source to a recipient. The concept is used across disciplines to describe how energy is conveyed, whether as heat, electric power, mechanical work, or biological energy flow. In English-language contexts the equivalent terms are energy transfer or energy transmission, but energiaátviv is used to emphasize the pathway or mechanism of conveyance within a system.

The scope includes several mechanisms. Thermal energy can be transferred by conduction, convection, and radiation; electrical energy by cables and transformers; and mechanical energy by motion, waves, or torque. In biological and ecological contexts, energy moves through organisms and ecosystems as chemical energy captured by photosynthesis and transformed through respiration and trophic interactions. The term is therefore applicable to engineering, physics, and life sciences.

Efficiency and measurement depend on the system boundaries. Energy transfer efficiency is the ratio of useful energy delivered at the destination to the energy supplied, with losses from resistance, friction, heat losses, leakage, and other irreversibilities. Accurate assessment requires clear definitions of the input, output, and time horizon.

Applications include power grids and distribution networks, heating and cooling systems, industrial processing, and energy budgeting in ecosystems. The term is less common in everyday language outside specialist Hungarian contexts, and its precise usage can vary by field.
