Blast husbanded

To take advantage
of the blast of wind
riing driven out by
the flash, make
it turn a windmill
which might be
vertical or horizontal .
As the whole current
of the air
might be confined
to the dimension
of the sail instead
of being diffused
extending through
the whole space of
the atmosphere
as in a common
windmill might
not the ?vane? be
made so as to
present always
their greatest surface
to the blast, and
their edge afarthing
had got out of the
reach of it?

Would the making
use of the wind
in this way retard
the blast considerably
so as to do
more mischief by
such retardation than
the benefit woulld be
worth?

N.B. the advantage
of such a windmill
the common one is
only the saving the time
that would be otherwise
lost by calms.

constantly more
rising between that
and the true one.

N.B. a very thin
sheet of water would
be sufficient.

As
be

As in the air chamber
there will be
some one present
at which it
will be more advantageous
to
have the focus
of heat than in
any other, say
the central point,
and as the magnitude
i:e:
the height of the
air chamber will
change with the
height of the water
in it , it will be
would be of advantage
if the
focus could be
made unviable,
so that its place
should be regulated
by the
height of the water
previous to the
flash.

29 The water in the ????tin?ber ttower will sink only in proportion as the air is let in and the air will be let in only in proportion as the water is let out, bulk for bulk - Therefore the full may be made to begin at any height within the 33, and the rising and falling and be only between the line of that greatest height and the line of the lowest height, wherever it was thought proper this latter should be situated Thence thin and be no bottom to or floor to the tower: it should stand upon arches, the crowns of the arches being not lower than the lowest height of the pond.
