Biomass Extraction of Energy Transformation

Journal of Advanced Research in Power Electronics and Power Systems, 2020
The focus of this is to make available clean energy, where there is a need for electricity production or energy infrastructure. An anaerobic digester contains an oxygen free environment that allows microorganisms to break down the organic material to harvest biogas (methane).

Energy Transformation

1979
Publisher Summary This chapter presents the basic definitions of energy transformation. Energy is the ability of a substance to move or to change other things. Heat is the energy transfer that is connected exclusively with temperature differences between two systems.

Semiosis and Energy Transformation

AIP Conference Proceedings, 2002
Semiosis is understood as a process of transforming energy to mass via measurement. Measurement is an action of codification, organizing energy within different modes of relation. Measurement is examined within a series of ontological and epistemological cuts that increase asymmetry by first differentiating energy/mass into external and internal realms

The Energy Transformation in Germany

2017
In the aftermath of the 2011 Fukushima nuclear meltdown, the German Chancellor Angela Merkel has advanced the reversal of her nuclear policy under the label Energiewende, which “refers to the move towards the age of renewables and energy efficiency. The German government decided that Germany’s energy supply should be generated primarily from renewables

Thermionic energy transformers

The Soviet Journal of Atomic Energy, 1962
The question of direct transformation of nuclear energy into electricity by thermionic methods is discussed. A comparison is made of the properties of various materials, containing fissionable matter, and at the same time having good thermoemissive properties. Results are given of transformation experiments in the active zone of a reactor.

ENERGY TRANSFORMATION FUNCTIONS

Journal of Meteorology, 1950
Abstract Separate energy equations for potential energy, kinetic energy of averaged motion, kinetic energy of eddy motion, and thermal energy are derived on the basis of four postulates concerning natural processes. The equations are transformed for use with space- and time-averaged values of the dependent variables in a general system whose boundaries

Transformation of magnetostatic energy

Journal of Physics A: Mathematical and General, 1994
Energy in a static magnetic field can be converted to other forms such as mechanical energy and heat. This is done by perturbing the magnetostatic energy by an electromagnetic wave-generating what has been described earlier as a 'companion wave'. When energy is drawn from this latter wave, the magnetic field decays.

Biological Transformation of Solar Energy

1960
Publisher Summary This chapter presents a description of a hypothetical solar energy conversion plant in which an algal culture pond, algal digester, and a thermal power generator are combined to transform solar energy into electrical power. Description, specifications, and cost estimates are provided for designing, maintaining, and operating each of

Energy Transformations in Photosynthesis

Annual Review of Plant Physiology, 1956
In the last five years the application of physicochemical techniques has made possible great progress towards an understanding of the mechanism of photosynthesis. Present evidence, to be discussed in the following sections, suggests that the reactions of photosynthesis may be divided into four groups.
