Practical Guige to Free Energy Devices

to pass continuously through a bubbler and the bubbler design has to accommodate that volume and yet ensure
that all of the gas comes into intimate contact with the water.
Perhaps then the first step is to establish a suitable pipe size for the gas flow. At this point in time it is not known
exactly what efficiency and performance can be expected from this particular design operating on 300 volts and
30 amps of current. It is probably safe to predict that the gas rate will not exceed 250 litres per minute which is
4.2 litres per second.
Passing through a standard 90 mm (3.5“) diameter pipe of 63 sq. cm. cross-sectional area that would require a
flow rate of 66 cm. per second or just over two feet per second. While that is possible and 10 bar pipe of that
diameter is available at £4.40 plus VAT per metre.
The next standard pipe size is 110 mm (4.3”) which has a cross-sectional area of 95 sq. cm. which would give a
flow rate of 44 cm./sec. or just under 1.5 ft/sec. which is a perfectly reasonable rate of flow. The cost of that pipe
in 10-bar rating is just over £6 plus VAT per metre.
The next standard pipe size is 160 mm (6.3“) which has a cross-sectional area of 201 sq. cm. which would give a
flow rate of 21 cm./sec. or just under 0.8 ft/sec. and the cost of that pipe in 10-bar rating is just over £14.23 plus
VAT per metre.
These figures indicate that cost is not a significant factor and while moving from a reasonably convenient 90 mm
diameter pipe to the much less convenient 160 mm size more than halves the flow rate, there does not seem to
be any reason to go over the 90 mm size. The actual gas pressure in the electrolyser will be held down to 5 psi
(0.36 bar) as compressing hydroxy gas is not a particularly safe thing to do. Consideration should be given to
using piping which is specifically constructed to carry hydrogen, but it seems unlikely that it would be readily
available in the larger sizes needed.
So, basing the bubbler dimensions on a 90 mm diameter pipe, the bubbler arrangement might be like this:
The objective being to ensure that there is a very large number of small bubbles streaming up through a
considerable depth of water. The most suitable dimensions are a matter of opinion but as space is not an issue I
would suggest the following:
The cross-sectional area of the inner diameter of the small diameter pipes laid on the bottom of the bubbler
should exceed the cross-sectional area of the main incoming pipe. For clarity, the above diagram shows just six
of these pipes but there is no reason why there should not be a much larger number. If there were just six pipes
and an incoming pipe of diameter of 90 mm, then the small pipe diameter would be 18 mm internal diameter or
greater.
It would also be good if the cross-sectional area of the holes drilled in these smaller pipes exceeded the crosssectional
area of the small pipe. As there should be a very large number of small holes, it is highly likely that it
desirable target will be met quite easily.
I would suggest that the depth of water above the top of the small pipes be eight inches or 200 mm and that
perhaps half of that depth be allowed between the water surface and the top of the container. The outlet pipe is
