NEW MOTIVE POWER.

The following are extracts from the interesting Ptqlie
read by Mr. Rowett, who was invited to explain' 1/w of
last meeting of the Polytechnic Society, the feattlre'dit
the important invention patented by Mr. Ale
Gordon, the eminent engineer : bed Its
"We shall now observe, that what cannot Its of
steam can be done by hot air, or by the hot Pont! 006
combustion, currents of which may be dischareedloi or
under water backward to impel the vessel forwaru'ea,
forward when the vessel is to be impelled baelloe
These currents, being permanently elastic, do not 0" the
as steam does; and being tenacious of their he3.l:', bet

The locomotive power of rockets is had by the direc ltea

~...tting these bodies in air or in water, with, tho
intervention of machinery ; and let it be observe all the
it is by making use of all the heat generated, and 3011
heated bodies put in motion. It is impossible tei ofe
that heat is the source of power in all the eases iovie
referred to. Mr. Gordon does, however, use sortie 5,,d for
machinery ; but it will be seen that it is not arratig'.o,
the delicate operations of the marine condensing engio•
but mainly to produce a reciprocating motion for P that

by Mr. Gordon's impeller, and this saving of P(''''erpir'

great loss of heat in the power of the fire, there are at!,
losses of the incondensed steam, the friction of tbe
the weight of the machinery, and the numerous roe
of resistance in the marine steam-engine, 21-r'
seems to my mind no doubt but this invention
re° too
Gordon's will save and employ advantageously ml,„1101°
half the heat now lost—in other words, less than LS, the
fuel now used by the marine steam-engine would ut; the
same work by Mr. Gordon's invention. Even

ducts of combustion would require as much fuel

" Mr. Gordon's intention is to use two furnaces,'
opening the top-bonnets one before the other, tleighf
three hours and 44 minutes, a sack of fuel 224 lbs. tight
could be shot into each ; the furnace bonnet lute, andagain, to remain so for three hours and 44 mioutei

by this mode of arrangement, Mr. Gordon conteo 100
consumption of fuel would not exceed 3 lbs. Per 410
power in practice—thus effecting a saving of fue; oloP:
of itself must recommend and ensure its eg nazi.
tion. But this is only one item in its economy—f?r iaora
an apparatus of 20-horse power would not COs'
than £350 to £4OO. I need not stop to coniPa',fitli
outlay with the expense of a marine steam engine' 03i
its chimney and paddles, or screw propeller, the P,..0303
almost ruinous cost of which, coupled with the eni leg
wear and tear, you are well acquainted with, anassit4
ready to acknowledge that in point of economy of Li vet
no very considerable advantage has been yet gained:o
sailing ships, notwithstanding the large amount of at 01,
science that have been applied to it. But let I.l'
take a glance at the apparatus as it is rePreseA
in the drawing, which is an elevation of one Lf A 01
Gordon's proposed engines. With two close nrsbi9
60 horse power—supposed to be seen on boar'A to
looking aft ; and unless our objector is bold enohul the
say the fire will not burn under pressure, and til%tbef
hot products of combustion have no power—le 400
words, that heat -is not the source of power in the
engine—he must admit that there is a rush of 'Juliet!
along the discharge pipe, and it is that power so °PI) of
which Mr. Gordon proposes to use under the quarto tot
bilges of a ship. The steam, which rises from the tiO
surrounding the close fires, drives the simple recifoc"cting
steam engine, and that engine works the double 'a
cold air pumps, and also the alimentary pumps f°r,,,;iol
plying the water to the boiler. The cold air, in PI it'
through the fire, parts with the whole or part go
oxygen to support the combustion. There heat is °,l
imparted to the water which surrounds the fire, su,bef,
whole products of combustion, mixed with smoke, 51
&c., rush out against the water to impel the cog' Gill
That the rush of the hot products of combustion too
propel the vessel is not a mere speculation depeod,erirdoo
theory. It has been practically illustrated by Mr-
'
on the Thames, and Mr. Gordon says ogel
persons have tried to bring the theoretical adv.3l:, tbe,
of heated air into practical operation to obvi

expenditure of
