BN 1000E
PERFORMANCE TESTED: BY GEORGE
WISEMAN
Yull Brown, in
his sales literature for the BN 1000,
(ExtraOrdinary Science issue OCT/NOV/DEC, 1993,
page 20) specifies:
Gas Production : (L/h) 1,000
Operating Pressure (Mpa) 0.45 (about 65
psi)
Power Supply Voltage (V) 220 (I assume
220 VAC)
Maximum Input Power (kW) 3.3
Max. Water Consumption (L/h)
0.55
Weight (Kg) 200 (about 440.8
lbs)
Cost retail $5,500 (direct from Yull
Brown, is now much higher from Dennis
Lee).
The BN 1000E
is one of a series of Water Torches built by
the Chinese after they invited Yull Brown to
their country to research his
technology.
Dennis Lee of
Better World Technologies is promoting this
electrolyzer series. He aquired the 'rights' to
it by partnering up with Yull Brown and then
negotiating directly with the Chinese to bypass
Yull Brown. Yull Brown died
pennyless.

Now, we have had
the opportunity to actually test a BN 1000E,
bought directly from Yull Brown
himself.
First I'll give
you the direct test results for the BN
1000E.
Then I'll give
you the data on the electrolyzer YOU can build
from Eagle-Research's Brown's
Gas books
. You'll see some differences.
(you'll see how
you can BUILD a better electrolyzer than you can
BUY, and for a fraction of the cost).
ACTUAL
TEST RESULT OF A BN 1000E (May,
97):
Gas Production (L/h) 900 (we could not
get 1,000 L/h)
Operating Pressure (Mpa) 0.06 (about 8
psi, obviously something wrong with the
pressure controls. The digital readout would
go to 0.6 Mp (87 psi) but the actual pressure
measured only 8 psi (0.06 Mp))
Power Supply Voltage (V) 235
(VAC)
Maximum Input Power (kW) 4.9
Max. Water Consumption (L/h) 0.38 (Lesser
water consumed because only 900 L/h
produced)
Weight (Kg) 225 (about 495.9
lbs)
Cost $5,500 USD direct from Yull Brown.
(note: prices subject to change depending on
dealer)
Note:
Yull Brown's own
specifications show inconsistency. I further
note that all the above figures that we tested
and found to be true, I later noticed that the
original specifications had been changed (to our
figures) by hand written notes in the BN 1000E
operating manual. I was told that Yull Brown
himself wrote those notes when the electrolyzer
was sold to Ben & Co.
Eagle-Research
Has Built a 1,000 L/h Electrolyzer With the
Following Specifications: You Can Do It
Too!
Gas Production: (L/h) 1,000 (can go to
3000 L/h)
Operating Pressure (Mpa) 0.45 (operate
between 65 and 70 psi)
Maximum Input Power (kW) 3.3
Max. Water Consumption (L/h)
0.42
Weight: all components (Kg) 125 (about
275.5 lbs)
Cost: about $1,000; home built, using
surplus parts.
Note:
We have now
developed our ER 1150 Water Torch, which will be
'store bought' for those people who don't want
to build their own Brown's Gas electrolyzer. The
ER 1150 Water Torch is even smaller, lighter and
more efficient than the 'home built'
specifications above. The price is higher
though, we're selling for a bit more than the
current retail price of the BN 1000E. Current
price on BN series machines can be aquired at
the web addresses (Dennis Lee distributors) on
my Brown's Gas links page.
Further Notes On Testing the BN
1000E
This report is
by George Wiseman, intended for public release
to increase the awareness for buyers and
operators of BN 1000E Brown's Gas machines. I
have found the instruction Manual to be
inadiquate for safe operation of the
machine.
I (George
Wiseman) have fully and independently duplicated
the technology needed to create Brown's Gas and
this is the first time I will have been able to
operate a "commercial" Brown's Gas machine
('store bought' as we'd say back on the farm). I
am uniquely qualified to test this BN 1000E,
having independently duplicated the technology
from scratch, I know what I'm looking at, what
should be there and what should not be
there.
Kiel Schweizer
and I arrived at Ben Missler's shop (7402 SW
Macadam, Portland, Oregon), May 18, 97 at 1:PM.
Ben Missler and Gary Robinson were
there.
We talked, had
lunch, set up some equipment and started
examining the BN 1000E. After getting somewhat
familiar with it (and having read the cryptic
operation instructions), we fired it up and
figured out the controls. We had a backfire (not
really loud) when I was shutting off the torch.
We saw the flash in the clear tubes
(plastic).
Note:
The China torch
is (in my opinion) really rinky-dink. The tip
would be nearly impossible to clean and it has a
knob to add oxygen instead of a lever (it would
be hard to hold the torch still while twisting
the oxygen knob to begin your cut). I recommend
changing the torch to an American model. I use a
Victor 100C on my electrolyzer in my shop. For
our tests of the BN 1000E we used (after
initially trying the China torch) my Victor
100C. Fittings to adapt the BN 1000E hose to the
American standard are available in most welding
supply stores.
Note:
Main power in
wiring code is Brown and White Power (240 AC)
and purple is neutral (note, BN 1000E manual has
different colored wires). Neutral is hooked to
the electrolyzer full wave bridge rectifier heat
sink bracket, which is grounded to the entire
frame of the machine. There is a 30 amp main
relay that most of the electrolyzer power goes
through (there is a small pair of wires that
routes 240 VAC directly to the electronics (has
smaller transformer dedicated to the
electronics), so the ON button can activate the
relay coil.
All the main
transformer power (one lead of the 240 AC from
the main relay) goes through what seems to be an
SCR; which seems to be controlled by the
electronics.
The main
transformer drops the AC voltage from 240 AC to
about 24 VAC, which is then rectified by huge
diodes in a full wave rectifier set up. These
diodes are mounted on a heat sink that is cooled
by a large fan. The fan turns on as soon as the
main relay is turned on and stays on till the
main relay is shut off (main power to machine is
shut off).
There are six
tubes mounted transversely in the bottom of the
box; they are about four inches in diameter and
17 inches long. Each tube has TWO "short cells"
mounted in it; welded together in the middle.
Thus the six tubes are each two cells; and the
electrolyzer consists of TWELVE cells. All
twelve cells are connected on the top with a
hose (left and right) and on the bottom with a
hose (left and right). These hoses seem to be
there to allow the electrolyte solution and the
gas to separate properly, yet keep the cells as
full as possible of electrolyte.
All four cell
hoses go up to the first transverse container,
that I'd call a liquid-vapor separator. The two
hoses from the top of the cells go to the mid
level of the liquid vapor separator (on the left
and right) and the two bottom hoses from the
cells go to the bottom of the liquid vapor
separator (left and right). The liquid-vapor
separator is about four inches in diameter and
17 inches long; it is located at the back of the
machine just above the end cell.
