3. Answers Elements
At the machine census level, we must recognize that we do not have as many tools or machines as we need, for example we do not know how to exploit the power of marine energies: waves, waves, that of extremely strong winds, storms, at Cape Horn, for example, nor the power of the Saharan ascendants, nor easily the power of periodic / jerky volcanic geothermal energy, nor that of ordinary air currents yet omnipresent.
And if these energies are not easily accessible to us is it not fundamentally because of this poor wealth of our catalog of generic machines?
In short, the viability criteria of current machines are "genetically" very enclosed / targeted for a very precise fluid nature, a strict operating perimeter, and a specific location to illustrate, we will never be able to power a wind turbine with water , make it work under the strong winds of roaring forties or position it so that it can exploit the Saharan ascendants, or impossible to put it in production mounted on the deck of a boat (except the small ones of course) .
Likewise, a hydraulic turbine will only be able to operate with water in the very organized perimeter of a reservoir or a weir, the same machine exposed to swells or waves will produce practically nothing except will remain motionless. .
A new generation of generic machine will have to be characterized by angles of use, a perimeter and a range of capacity to produce much more open and in all the aspects available in nature: change of state of the possible fluid (vapor-water hot and vice versa) in production geothermal geothermal source for example.
Accepted regime change and restart at any point in the cycle (pressure-depres- sion and vice versa) in marine wave generation.
An inventory of sources (geographic and by nature), a library of formatting or flow routing equipment and a development of the range of machines must serve as support for innovation.
4. What new requirements or criteria?
"Fugitive, capricious or violent inconstant flows"
If it was necessary to draw up specifications to organize the operation of a new machine.
a) Versatility:
Versatility of feeding abilities with regard to the range of available feed fluids - compressible and incompressible
b) Minimum inertia:
A very low internal inertia to accept the sudden variations of intensity of feeding and also all unexpected changes of the direction of rotation.
c) The durability of the movement:
A perfect cycle of operation in rotation, ie 100% of the cycle producing traction without any dead point.
d) The regularity:
Torque at low speed and a constant value of the torque restored over the entire cycle.
e) Performance:
A volumetric operation avoiding losses of energy and able to recover and convert the least amount of energy introduced in the form of pressure flow.
f) The starting autonomy:
A capacity to start alone, according to the natural diet.
g) Reversibility:
Operation in pressure as well as depression, only the direction of rotation is affected.
h) Simplicity:
Simplicity of design and manufacturing and hardiness of operation which must ensure a durability of the behavior in time and easy maintenance including under conditions of intervention naturally difficult.
i) Modularity:
An ability to be organized / coupled in a multi-machine system to add power.
