The celuloid wind zcreens of auto
mobiles give great risk of fire. Very
( fine copper gauze is said to have proven
A satisfactory substitute, being easily
seen through and non-inhammable,
while it does not crack like celluloid.
The low efficiency of the steam en-
CINE tempts inventors with great posi-
bilities Of saving fuel. NJ. Cantor, a
European engineer, has hit upon an
altogether new form of heat engine,
and proposes to use for power the eX-
pansion of the gas produced by the
burning of liquid fuel-like petroleum
and alcohol-when sprayed upon a
white hot oXidizing material, like
oxide of copper. The oxygen removed
from the copper Divide would be re-
stored by an air jet. Pending practi-
cal test it is claimed that the highest
possible rate of expansion would be
produced in the working gas, and that
Ia greatly increased thermoydynamic
deficiency would be secured.
Professor w. e. Ayrton points out
THAT the common expressions buying
Electricity" and consuming electric
mrent" are misleading. No electrici-
y is used up in lighting buildings,
aying machinery, and propelling cars
nd trains. Just as much electricity
lows away per minute, through the
return conductor, from your electric
q & lighted house as flows to 1t
through the coming conductor. The
aectric current is like a butchers cart
arrying round meat-you no more
eonsume current than you consume
cart. 1t Is not the vehicle but what 1t
leaves behind that the consumers buy,
meat in the case of the butchers cart
and energy In the case of the electric
current"
