What Are Photosynthesis and Respiration?
» ~ Specialized applications of E & M fields, heterodyned hyperfine structure frequencies ( e.g., alpha rotation-vibration constant ), splitting frequencies, spectral signatures @ resonance, etc., affect chemical reactions and biosystems.
» ~ Optimizes combustion w/ 90-95 % humidity; improves all aspects of engine performance.
» ~ Excerpt, Chap. 3 from The Fish Carburetor Book (1982).

These materials are all derived from ancient plants and animals, and theenergy stored within them is chemical energy that originally came fromsunlight through photosynthesis.

Why not just burn hydrogen in an internal combustion engine and forget the high tech fuel cell and reformer? You can, but compared to other fuels hydrogen is a lousy motor fuel. It has a very low octane number, which means it causes detonation and preignition unless the compression ratio is cut way down. It also tends to backfire through the intake manifold. And it doesn't get very good fuel mileage, either. A gallon of liquefied hydrogen has only about one fourth the energy content of a gallon of gasoline.
Hydrogen is one of the most abundant elements on Earth. It can be made from natural gas, oil or even coal, or by using electricity to break down water into hydrogen and oxygen. Even so, it is expensive to produce and contains much less energy per liter than other hydrocarbon fuels.

Thermochemical conversion, characterized by higher temperature and conversion rates, is best suited for lower moisture feedstock and is generally less selective for products. Thermochemical conversion includes incineration, pyrolysis and gasification. The incineration technology is the controlled combustion of waste with the recovery of heat to produce steam which in turn produces power through steam turbines. Pyrolysis and gasification represent refined thermal treatment methods as alternatives to incineration and are characterized by the transformation of the waste into product gas as energy carrier for later combustion in, for example, a boiler or a gas engine.
Respiration occurs in your cells and is fueled by the oxygen you inhale. The carbon dioxide gas you exhale is the result of a completed cycle of cellular respiration.

Artificial Photosynthesis; Types of Solar Energy; ..
Nowadays, waste-to-energy plants based on combustion technologies are highly efficient power plants that utilize municipal solid waste as their fuel rather than coal, oil or natural gas. Far better than expending energy to explore, recover, process and transport the fuel from some distant source, waste-to-energy plants find value in what others consider garbage. Waste-to-energy plants recover the thermal energy contained in the trash in highly efficient boilers that generate steam that can then be sold directly to industrial customers, or used on-site to drive turbines for electricity production. WTE plants are highly efficient in harnessing the untapped energy potential of organic waste by converting the biodegradable fraction of the waste into high calorific value gases like methane. The digested portion of the waste is highly rich in nutrients and is widely used as biofertilizer in many parts of the world.
Relation of Combustion, Respiration and Photosynthesis
Large quantities of crop residues are produced annually worldwide, and are vastly underutilised. The most common agricultural residue is the rice husk, which makes up 25% of rice by mass. Other residues include sugar cane fibre (known as bagasse), coconut husks and shells, groundnut shells, cereal straw etc. Current farming practice is usually to plough these residues back into the soil, or they are burnt, left to decompose, or grazed by cattle. A number of agricultural and biomass studies, however, have concluded that it may be appropriate to remove and utilise a portion of crop residue for energy production, providing large volumes of low cost material. These residues could be processed into liquid fuels or combusted/gasified to produce electricity and heat.
Forms of Energy: Motion, Heat, Light, Sound
There are a wide range of animal wastes that can be used as sources of biomass energy. The most common sources are animal and poultry manures. In the past this waste was recovered and sold as a fertilizer or simply spread onto agricultural land, but the introduction of tighter environmental controls on odour and water pollution means that some form of waste management is now required, which provides further incentives for waste-to-energy conversion. The most attractive method of converting these waste materials to useful form is anaerobic digestion which gives biogas that can be used as a fuel for internal combustion engines, to generate electricity from small gas turbines, burnt directly for cooking, or for space and water heating. Food processing and abattoir wastes are also a potential anaerobic digestion feedstock.

Power plants transform one form of energy into a very useful form, . Coal and natural gas plants use the chemical potential energy trapped in fossil fuels. Nuclear power plants change the nuclear potential energy of uranium or plutonium into electricity too. Wind turbines change the kinetic energy of air molecules in wind into electricity. Hydroelectric power plants take advantage of the gravitational potential energy of water as it falls from the top of a dam to the bottom.
