Summary: background and purpose of the invention.
Historically, nature disperses a lot of energy to the surface of the planet, yet man uses only very little power contained within this multitude of streams. These flows are varied, different, fleeting, fickle, capricious and violent, how to better use?
Fringes, entire fields of natural energy are currently "fallow": very weak and vulgar energies of air currents, very brutal and unpredictable storms, very strong of the Saharan ascendants, or even irregular in regime and / or in nature of volcanic geothermal energy, the smoothed energy of slow rivers, fast torrents… solar energy, marine forces, will all this one day be made more available to consumers?
Both individual production than for a heavy and mass production, it is urgent to organize better result in our quest, or rather our human bulimia, but insufficiently shared, domestic energy.
Faced with unreasonable management, excessive and even risky fossil fuels and nuclear energy, there is room to roll up our brains, to innovate, to invent, to test new concept adapted machines. Better use of all these riches which disperse: quickly invent the generic machines need to access the immense natural generosity.
1. Introduction, Questions
A few basic questions: What would it take to better succeed in the challenge of the 21st century, this energy challenge "to better convert the entire range of natural energy flows"? ...
What simple machines which source? What criteria of sustainability? What scope of operation? Possible additional systems required for water supply and or formatting the natural flow? What criteria to characterize the simplicity and the required extension of the machine, the machine set + supply system? Locating energy zones of the planet? These areas are they to areas of high population density, so consumption? Realism interconnections? On such projects, what should be the contributors? How to extract the pool of existing inventions simple machines, efficient and versatile tomorrow? How effectively and efficiently innovate paying much more attention / acuity natural energies?
I will try to start the answers ... start the solutions.
2. Study of the existing: the current generic machines
How to meet our current machines in the quest for renewable energy?
These machines are generally single type of fluid (compressible and incompressible) and little or not accept operating irregularities (supply irregularities, rapid change of engine speed, reversing), perimeters and environments are still too narrow, too specialized, too rigid. Faced with a large nature diverse, changing what have we already implemented?
a) Wind turbines
those useful for grinding grain or up water have been somewhat forgotten ... only the wind to produce "massiquement" electricity have recently had a strong development.
They become monstrous because the man wants the powerful and function is effective with winds in excess 15km / h and less than 80 km / h.
Outside this range do not produce or are in a critical risk area of operation. Vast wind fields are under construction and in operation.
b) Hydraulic turbines
The energy of falling water is used for a long time, it must nevertheless be seriously formatted through weirs, dams or installing gigantic dam type for that output of a turbine system, for example of the type "Pelton "(operating at high pressure), can then drive an alternator and produce electricity.
Beyond these well-known 2 generic machines, are there actually other with also popularized use?
I think not… yet Montgolfier's hydraulic ram pump was an admirable generic machine invented and designed in the 18th century and strangely forgotten today.
The tidal power plant of Rance is a special case, a system and not a generic machine.
Other machines designed for other operating conditions can also be adapted to machine convert natural flows: internal combustion engine, steam piston connecting rod crank, gas turbine, vane motor, hydraulic motor gear Or other. However, the food in adaptation with the natural fluids often go even more complex and thereby they become specialized and require specific operating conditions and very stringent. Outside their narrow scope, they no longer work or appear extremely low yields: administer a natural fluid pressure in the combustion chamber of an internal combustion engine while it is at bottom dead center. He has no traction on a relatively large angular aggregate.
