Two Heat Cycles are Combined . . . .
     
                   So why
does the engine function 
more efficiently 
using two heat cycles? 


    The FE combines BOTH the
Rankine heat cycle (steam), and the Brayton heat cycle (reaction turbine). 
This combination of heat cycles provides the means for the engine to
maintain a constant RPM, even when using a waste heat source. 


This point alone has been a major reason for the many
failed attempts to use waste heat as a primary heat source.  In other 
instances, high-speed turbine engine failure means costly down-time. 


(Note: certain key design elements are not being
disclosed regarding this critical point.) 

    A
constant RPM is required for effectively and efficiently running an electrical generator, so  there are not wide
fluctuations in the electric cycle.  The design of the
FE
-4  (not shown) is able to instantly compensate for rapid changes in
load-demand, as  well as sudden variations in BTU (heat) output, even when
using  waste heat, as its primary heat source.  


    Therefore, the FE is ideally suited to run
an electrical generator, using a combination of waste heat, and even solar
heat.  

    As stated, the key component of
the Fibonacci Energy System is its uniquely designed external
combustion Fibonacci Rotary Expander Engine (referenced to as the
FE).

    Its unique, patent-pending components
are combined in a manner which results in a very highly energy-efficient power
system.

    The Rotary Power System can be
configured as either an “open-loop” system, or “closed-loop”
system
. When configured as an “open-loop” system, it is ideally suited to
run as a rotary steam engine. 


    This  means as an “open-loop” system, that the
working fluid is water. When  the water is heated, and turns to steam, there is
of course, some loss  of water. But some of the spent water can still be
re-captured,  re-condensed, and re-circulated. 

   
When the Rotary Power System is configured as a “closed- loop”  system, a
specialized working fluid is used as the primary working  fluid. It goes to
vapor-phase at about 90F.  It is commonly known as  “Organic Rankine Cycle”
fluid, or ORC.  

    An external
combustion Burner
provides the ability to utilize many types of fuel, with
either an open-loop system or closed-loop system. 


    Examples  of fuels which can be used inside the
external combustion Burner, include  waste crankcase oil, waste transmission
fluid,  natural gas, propane gas, and even liquefied powdered coal. 
  

    Because the FE is a heat
engine, the heat  source can also be waste heat from just about any source. This
ranges  from geo-thermal heat, to the waste heat generated at a dry cleaning 
plant. It also includes the waste heat generated from photo-voltaic cell 
banks. 

    The Engine can even run on compressed,
outside air, and the air is ice-cold as it comes out of the 'exhaust
port'.   The exhausting air is cold because the engine extracts the
heat energy from the air, and converts the heat into rotary shaft power. 
(Note the low exhaust Temperatures   in the videos.)

 A
hybrid, combination of heat sources, can also  include Solar Heat, thereby
further increasing the over-all  energy efficiencies of the Fibonacci Energy
System.    
           
         
This briefly
highlights some of the reasons The FE is the Ultimate Prime
Mover
Engine,
     
              and why it is has also been
called the “Game Changer Engine” of the 21st
Century.
