How does chemical energy work?
Chemical Energy in Everyday Life 1 We know that plants need solar energy to produce sugar from carbon dioxide to water. Sugar, water and carbon dioxide stay together by chemical bonds that hold the chemicals together. 2 For instance, all sugars consist of oxygen, carbon and hydrogen atoms held together by chemical bonds. These atoms do not connect together automatically; rather some energy is required to make them stay together. 3 Plants use solar energy to put the hydrogen, the carbon and the oxygen atoms as a whole in the form of sugar. This is a suitable example of energy transformation where energy is transformed from one form to another. Here, solar energy is transformed into chemical energy and prevents from falling apart.

Where does energy come from in erythrocytes?
Here is the path in which energy is produced. Originally, erythrocytes receive energy excitation in the capillaries of the lungs from free electrons and negative ions coming with the inhaled air. They start the process of free radical oxidation of fats of cell membranes, as a result of which, end products of oxidation, namely oxygen, ketones, aldehydes, alcohols, etc, are created with exciting external electronic levels. In other words, cells generate a huge amount of free electrons, ready to give their energy.

An important value of muscles consists of their ability (during contractions) to create a difference in electric potentials. Due to the difference in potentials, electrons receive additional stimulation for their movement in organs, tissues, and energy meridians.
How does food provide energy?
The energy that food provides to the body consists of the potential electrons’ energy stored in the chemical bonds of natural products. When macromolecules are cleaved by enzymes, these electrons move from high energy levels to lower ones, forming an avalanche-like flow of negative particles and cells to maintain their vital activity.
What is the energy informational flow?
The energy-informational flows of cosmic radiation consist of ultralight microparticles, which are received by special receptors in the area of the head and perineum and pass through the energy spine. These flows are also received and accumulated due to the internal cavity structures of the bones of the human skeletal system. Energy-informational vortex fields are created by the above mentioned flows and rotate in planes perpendicular to the channel of the spine. It is these fields that are called the aura of a person.
