## HAAM and Second Law of Thermodynamics

In laymen's language, as far as HAAM concerned, the second law of thermodynamics states that you can not make some thing from nothing. HAAM sounds contradicting this second law of thermodynamics as it generates an extra output without extra input. HAAM sounds it generates extra output without extra input on a simplistic observation. But actually on a deeper observation you can see it does get extra input to generate extra output. This is explained on figures bellow.

In figure 1 above both propellers operate with an external input like electrical power. Both generate outputs as higher pressures 1 and 2. Both higher pressures, 1 and 2, are less than the input used to operate both propellers. This is because both propellers use some of the output internally to overcome friction and the weight of moving parts, and some of the output wasted as heat.

Figure 2 above is the same like figure 1 but both ducts redesigned as in the figure. Both bend at front to link to each other. This redesign causes to generate a third output, higher pressure 3 at HP point, when both propellers operate. Higher pressure 3 generated because of lower pressure at LP point. In other words lower pressure at LP point acts as input to generate higher pressure 3, which is the extra output without cost. So there is an input to generate the extra output. Therefore HAAM doesn't contradict second law of thermodynamics.

HAAM is a two parallel operating machine. One of them is hydro-atmospheric without moving parts and uses hydro or atmospheric pressure as external free input, figure 3. It generates an output equal to the input because it doesn't need to use any energy internally. The other machine is electric machine, figure 3, with internal moving parts, which have weights and cause friction, and uses external input to operate. This electric machine uses some of the energy internally. So it generates an output always less than the input.

But the hydro-atmospheric machine parallel to this electric machine generates an output at least more than the energy this electric machine used internally. So the output of both machines should be more than the external electrical input. If both machines can generate an output more than the external electrical input theoretically HAAM can be made as self-sustaining and energy-providing machine on a samll scale.

No one is encouraged to try to build a self-sustaining and energy providing HAAM. Because it needs a lot money and you have to be an expert and qualified more than enough in this field. The most efficient machines are hydro power machines like hydro-generators, which claimed to have around 90% efficiency. A chain of three or more HAAMs, each one acts as input to the next one, could operate to sustain itself and provide energy if hydro power used as input. This can be further improved if the machines operating inside water and all outputs kept mechanical. However this can be done only on a large scale.

Electric power could be used on a smaller individual affordable scale. Weights are going to pose serious hurdle because a HAAM is a moving machine. So the lighter is a HAAM, the less energy is wasted. The output of a HAAM is a moving energy or a mechanical power. To convert this mechanical energy to electrical energy the HAAM and its path can be looked at as an electric generator. In this case the path is made in a circular shape and covered with a coil all around. The HAAM caries a magnet. As it goes around it it converts moving energy to electrical energy across the coil.

HAAM is propeller-driven. This causes drag, which can waste energy of hydro-atmospheric part. Because of that a HAAM can be made powerful enough but not very fast. This will become a disadvantage if a HAAM carries magnets to generate electricity because to generate electricity it has to move very fast. To overcome this disadvantage, the blades of propellers can be made from magnets. This has extra advantage in weight reduction. Because propellers spin vertically very fast and anything spins fast vertically almost becomes weightless. In this way, the weight of mechanical to electrical conversion of HAAM is eliminated, see the figure bellow. If it is not eliminated completely at least it will be reduced a lot.

To generate power a HAAM has to move none-stop, which means it has to travel on a circular path. This generates outward thrust, To control outward thrust, the circular path could be made like a cylinder and the HAAM made to travel around it inside at 90 degree to cylinder wall.
