Pop-pop boats maybe
- Hi all,
This post should prove to Yasar and
everybody else that I am not an engineer
and that I never have been one! I do come
up with something every now and then,
usually by "borrowing" it from somebody.
This suggestion was originally based on
a photo of a folded coil boiler I borrowed
from the Pop-pop Pages.
Go to: http://tinyurl.com/oomal for a look.
It evolved a bit after Richard Jenkins wrote
about his discovery that a square tube
boiler is more efficient than a diaphragm
boilers. When he posted the photos of his
"Popflea" and "Firefly" boats I decided his
horseshoe shape square tube boiler was
also the most compact boiler I have seen
and decided that several of his compact
boilers could be heated by the same burner.
A more or less 3-D view can be seen at:

and information I haven't developed yet.
A layout at: http://tinyurl.com/gcbdh
shows something that might be
controlled the same way a R/C boat
layout at: http://tinyurl.com/gd8gg
would be by selectively closing normally
open, two-way valves. There is a paddle
wheeler layout at: http://tinyurl.com/hqhzn
that could be controlled the same way.
Go to: http://www.minivalve.com/ for
information about miniature plastic
duckbill valves that might be used to
maintain unidirectional flow from
inboard supply tubes through several
horseshoe boilers and out through two
outboard propulsion tubes with valves
that could be closed by radio control
servo-mechanisms. I don't believe the
output of several boilers could be
ejected through the same propulsion
tube without some provision for uni-
directional flow, because some boilers
would be sucking water in at the same
time that other boilers were ejecting it.
This could be represented by the
Best wishes, old Frank
