Hey Folks,
I have been looking at the diagrams and pictures of
this device, trying to figure out the theory of operation,
( true or not, there has to be a "theory" )
They show a picture of a black coloured "Haskel" pump.
This is used throughout the gas/oil process industry as a very high pressure
pump.
Typically with a supply operating pressure around 100 psi,
the pump head kicks out 4,000 + psi.( for the size of pump shown in the
picture )
It can be used to pump Hydraulic fluid, or as a gas pressure amplifier.
Air is usually used to push down on the Top Piston ( very large surface
area ). This is directly coupled to a bottom much smaller piston,
which is the High Pressure pump.
Now instead of using Air to operate this Top Piston, lets put this Pump
in the bottom of the device, and use the Reciprocating Central Rod
to activate the Top Pump Piston, instead of Air.
This will give a Very High Pressure Gas Supply. This High Pressure gas
appears
to go to a standard "Shell and Tube" Heat exchanger ( bottom Co2 Cylinder
in the Diagram).( Question ? At what Pressure can Co2 be liquified, I dont
Know ).
Some form of heat applied through the Heat Exchanger Tubes, and the
warmer/hotter
Co2 rises in to the second Co2 Tube.
( By the way, these Co2 "tubes" look very similar to Hydraulic/gas
accumulators,
used to store Energy as Pressure. From the Photographs they appear to be
manufactured
to withstand very high pressures, as does the central "cylinder" ).
Gas from the top "Accumulator" then appears to go to the central "Piston
Cylinder",
where a reciprocating piston alternately covers/uncovers each entry port,
allowing gas
to enter the piston chamber. Now, if these entry "Ports" had an orifice
plate in there
( restriction ), you could get a JT effect as the Highpressure gas "flashes"
in
to the cylinder. If there was a large Differential pressure Drop, across
this piston,
there would be a massive temperature drop.On the facility I am currently
working on,
a JT drop across a valve of about 100 psi, gives us a target temperature of
-14 F ( also dependent on gas velocity, which is controlled, and a few other
factors).
Squirting very cold gas either side of this central Piston "MAY"??? cause
this Piston to
Reciprocate ( aka Stirling Engine ). The Gas then exits through the other
side of the cylinder
as Very Cold Gas,( hence Blue Coloured line in diagram ) goes down to the
High Pressure Pump, where the cycle repeats itself.
I guess you can make an Electrical Generator using a reciprocating
Core/coil, instead of
a rotating one ?? (That side is beyond my understanding of Electrical
Equipment)
Problems that I see with my understanding of this :-
There appears to be some Key components missing to make it work (good idea
if you want to keep
it secret )
There appears to be no input power/fuel required. ( I have a Big Problem
with Eternal Energy
Machines ).
It may require "priming", i.e, the reciprocating piston has to be manually
moved to prime
the Co2 cylinders to get it to the required "starting" pressure. In which
case is the output
or run time not the same as the Energy needed to Prime it in the first place
? ( less Friction losses )
I may have got the "Heat Transfer" theory completely the wrong way round. (
in which case
I do not understand it ! )
It was interesting. I would like to buy one that works. I would not like to
invest money
in its developement.
Just my 2 dollars ( pounds , pesos, lira ) worth

Hey Steve thanks for the endorsement but I don't walk on water. As far =

right to recoup their intellectual capital.
Adriana
Now that's a novel approach. "A kit you can buy." Wow, somebody else =
has something to sell.
When Paula and/or Adrianna says this is something to look at, I will. =
Until then, it is just somebody trying to sell something.

It's a "no batteries included" device.
You supply the power so it can convert the power you supply.
It's stated on their web site.

Thanks Marc,
Must have Missed that.
Thats got to be the final word then.
What a waste of steel

Thanks guys for all your advice, well appreciated !
I do not wash the lettuce. I just placed them in open plastic bags , at
around 10C and delivered them within 3 -4 hours. The restaurant ties a knot
around the bags, and stores them at 4C. I only deliver 45 heads a week since
I am still in the research stage ( going very well by the way thanks to you
guys ). I plan to go commercial within the next year or so and was worried
about the fragility of the plant. I guess I will pay more attention and
store at 32-40 F as recommended. I left a lettuce head in my truck once
at -30C, it shattered like glass the next morning ,it was quite a sight !
