Roz nholz's Great Idea.

Idaho. where for the past year or more he
has been drawing on the gray matter in
his brain to cOncoct schemes to utilize the
power of an angry surf.
He saw that when old ocean gets IFS
back mp and begins to lash out itself in
dead earnest there was deal of motor
power exhausted.
That same power, he medi!ated, put to
more unitarian purpose than that of
wrecking ships and drowning men, might
be made of some service in. human
economy.
So he contrived this boat that is guaran-
teed TO be propelled by the action of the
waves alone. The angrier the sea the
more power generated. There are no fears
of the boat upsetting and drowning the
crew, for 1t Is wa.er-tight concern
throughout and so weighted al the bottom
that if It should be overturned it must of
necessity right itself Immediately, like
cork with nail in the end.
At least the boat that RsZenholz carries
under his arm appears to have all these
attributes and if it is hall what its inventor
SAYS il is it is certainly all of this.
Of course, the boat that Mr.. RoZenhoz
carries under his arm is not quite large
enough to do much real PRACTICAL human
lie saving i'll, but he saws larger boat
butt en- the same plan will make the noble
profession of life saving a pastime and
pleasure compared with what it Is now.
At the present time life-savers are not
classed as Al risks by the actuaries.
Should this new-fangled boat come into
service all this would be changed, and
writing policies on Iiie-savers would be a
pref Die branch of the business. So the
insurance men are interested. or ought to
be. in the success of this double-hull in
Vention.
Mr.. Rozenholz's model works like a
charm on dry land. II you move the for
ward hull in the manner you think the
H.
moves admirably. and the faster You move
the false bow the faster the wheel turns.
Manifestly the boat would be of but
little service in dead calm, but as life
saving boats are usually needed wien the
waves are running the usual mountains
high" Mr.. RoZenholZ says this point is
nothing to its discredit.
Like good many other enthusiastic in
vent0rs. Mr.. RoZrnh0lZ is not troubled
with the possession of more of the worlds
goods than is sufficient 10 pay his wash
bill and rent as they come due. And this
is why 1t is that be has not already built
one or two big boats like his model, and
demonstrated to a doubling world that
the mad sea waves may DE employed to
propel boat to rescue the lives they try
10 drown.
In a thirty.foot boat, eleven HORSEPOWER
is generated by the action of an ordinary
surf IN an ordinary heavy sea, the in
ventor has calculated. And he has the
hgnres to prove Ii.
For days and weeks he has been wander
Ing along the seashore with long plank
and some instruments. With these he has
been calculating the force of waves until
he has compiled a whole mass of tables
and figures and got it all down so fine tina.
he saws he can convince the most skept-
cal, If allowed TO talk to him long enough.
Mr.. RoSenholz also mas a plan-aud a
patent OH the plan-for utilizing the wave
powers around the coast of San Francisco
in mechanical pursuits. He is confiden {
he can produce all the power needed to
turn every cOgwheel in the city and supply
every dynamo run for the bare cost of
building huge scow in movable sections
and anchorlng it off the beach near Seal
Rock.
OF course, a hundred thousand dollars
or so would be needed to build the right
kind of a scow, but when built and in
running order there would be no charge
for fuel.
just at present Mr.. Rosenholz Is engaged
in waiting for the appearance of available
cash capital wherewith to launch his
patents. Should some man with long
purse and firm belief in the RosenhnIZ
idea OF life-savDg boat come along at the
opportune moment, the ife-saving officers
of this port will have the desired opportu-
nlty TO test the new boat, for Mr.. Rosen-
hoiz Will build upon the slightest provoca-
ton possible. He swears it.
