undergoing a double spiral centripetal contraction. It leaves the
lmm diameter nozzle (there are 4 per pipe) with tremendous force
because of its density and high velocity. The exit velocity of the water
is about l,290m/sec, (four times the speed of sound), which makes
it as solid and hard as steel wire.
The following is the eye-witness report of Gretl Schneider, who
accompanied Arnold Hohl, one of Viktor's observers:
Mr Viktor Schauberger has demonstrated the machine to me.
The previous huge construction is no more. It has been
reduced to half its former size and in operation develops enor-
mous power. I poured a pot of water into the bottom of it. The
machine produced an almost inaudible sound and then a 'pfff
in the same instant and the water pierced right through a 4cm
thick concrete slab and a 4mm thick super-hardened steel plate
with such force that the water-particles, invisible to the eye due
to their high velocity, penetrated right through all clothing and
were experienced as lightning needle-pricks on the skin. Water
glass was also passed through and solidified in 5cm long hairs
on the outside of the casing, like bristles.^11
Some of Viktor's machines did not need a starting motor, and
would get going on their own with a few cranks of a manual start-
ing handle. The heavy centripulser perhaps required one, but after
gaining sufficient speed would produce sufficient energy to self-
rotate. If the machine works as Viktor claimed, the generator
should produce ten times more power than the motor needs, or a
ninefold surplus of electric current. One of the problems with Vik-
tor's machines was more how to stop them than getting them
started. Another was keeping the machine anchored to the floor to
stop the strong levitational energies that were generated from lift-
ing it into the air.
The repulsine and the flying saucer
As we described in Chapter 1, there were several models of this
machine developed, the first in 1940 to investigate free energy pro-
duction, later to validate Viktor's theories about levitational flight,
but in the mid-1940s as prototypes of a new secret weapon of the
Third Reich:
