In the present invention, above and certain the numerical value A of certain numerical value A includes given figure A below.
The inventor thinks according to thermodynamic (al) basic principle and on the observation of universe phenomenon: do not having under the prerequisite of external factor impact, heat can not absolutely convert other any type of energy or material to.In the tradition second law of thermodynamics, only set forth and do not had under the prerequisite of external factor impact, heat can not absolutely be changed successfully, and this law is correct, but is unilateral.Can heat be defined as with popular language to the minimum form of energy, or be the rubbish in universe referred to as this.By analysis, the inventor also thinks: the growing process of any biology (animal, plant, microorganism, virus and bacterium) is all heat release.By analysis, the inventor also thinks: any one process or any one circulation (are not limited to thermodynamic process, for example chemical reaction process, biochemical reaction process, photochemical reaction process, biological growth process, growing process are all included) its maximum acting ability conservation, the inventor thinks does not have photosynthetic growing process can not improve its acting ability, that is to say, the acting ability of bean sprouts is the acting ability sum that impossible add the nutrient of its absorption higher than the acting ability of bean or pea; Why the acting ability of one tree wood is greater than the acting ability of sapling, is because sunlight has participated in the growing process to trees by sapling with photosynthetic form.
The inventor thinks: the basic logic of heat engine work be restrain-be heated-disperse.So-called convergence is the increase process of the density of working medium, and for example condensation, compression all belong to convergence process, and under same pressure, the working medium degree of convergence that temperature is low is large; It is exactly the endothermic process of working medium that what is called is heated; What is called is dispersed the process of the density reduction that refers to working medium, for example, expand or spray.Any one disperses process all can form the reduction of acting ability, and for example, the acting ability of the air of gaseous state will be well below the acting ability of liquid air; The heat that methanol plus water adds moderate temperature generates carbon monoxide and hydrogen, although the carbon monoxide generating and the ignition heat of hydrogen are greater than ignition heat 20% left and right of methyl alcohol, but it is very little that its acting ability is greater than the ratio of acting ability of methyl alcohol, although its reason is this process and inhaled the heat of 20% left and right, the degree of divergence of resultant carbon monoxide and hydrogen is far longer than methyl alcohol.Therefore, utilizing physochlaina infudibularis that temperature is not high to add chemical reaction is the acting ability of having no idea effectively to improve resultant.
The inventor thinks: it is the process that entropy increases that distance increases, and the distance between cold & heat source also affects efficiency, and the little efficiency of distance is high, and the large efficiency of distance is low.
In the present invention, should, according to the known technology in heat energy and power field, in necessary place, necessary parts, unit or system etc. be set.
beneficial effect of the present invention is as follows:
Volume of the present invention is little, specific power is high, low cost of manufacture, and the motor that can be used as the aircraft such as target drone uses.
