Figure 4 The Principle of Heat Conversion

Figure 4 shows the principle of heat conversion, such as is commonly applied in a home water boiler. Comparing the input-output relationships mentioned in the previous section with those of Figure 4 results in the correspondences shown by Table 1.

**Table1 Input-Output Relationships of Each System**
System		Input①	Output②	Input③	Output④
Heat Conversion		Cold water	Hot water	High temperature	Low temperature
Economic system	Production	Resources	Commodity	Labor	Waste
	Consumption	Commodity	Labor	Household labor	Waste
	Decomposition	Waste	Resources	Labor	Useless heat

By treating resources, labor, commodities, and waste as economic components, and treating matter, energy, information, and entropy as physical elements, the following correspondences, listed in Table 2 are established between them.

**Table 2 Economic Components and Physical Elements**
No.	Economic Component	Physical Element
(1)	Resources	Matter and Information
(2)	Labor	Information and Energy
(3)	Commodity	Information and Matter
(4)	Waste	Matter and Entropy
(5)	Useless heat	Entropy

It is a general approach of science to reduce a substance to its elements; i.e., a molecule is made up of atoms.

The circulation of the aforementioned economic components, as controlled by market mechanisms, is observed outside the production-consumption-decomposition system. Inside each of these systems, the exchange of physical elements is observed as shown in Figure 4 The Principle of Heat Conversion. The economic process can be defined by the flow of these economic components and physical elements, as shown in Figure 5 A Metabolism Model.
