Western Canadian farmers lust
140,000,000 bushels of grain last
year due to the heavy infestation
of weeds, H. W, Leggett of the
Federal Dpartmnt of Agricul-

conference of the Canadian Agri-
cultural Chemicals Association.
Mr. Leggett who is superin-
tendent of the government ex-
perimental station at. Regina,
said that of the 45,600,000 acres
in the four western Proyinces
planted in cereal cr• op s, ".about
12,000,000 were sprayed with
2, 4-D chemical weedkiller. This ;
compares with 500,000 acres
sprayed in 1947.
"By breaking down, a few prej-

As 'Dr. ,Farrington Daniels of

I of the' leading„ai4arInergy sci-
entists .in the United States ex-
plained it, this is a challenge to
the intelligence of men to use the
abundance that is in the sunlight
around us.
The 'supply ofithis,aunshine is
enough td meet many of the en-
ergy needs of mankind for mil-
lenniunis to' icoine, he said. But
it will take a long, hard research
effort to take practical advantage
of any really large amount of it.
This, then, is the experts' es-
timate of rap lied solar energy
and its prospects as 'sketched by
the five days of meetings—some
limited applications immediately
and a challenging promise or
the future.
"There is no sudden . era of
solar prosperity just around the

added „that he ekpeets,seler en-

This is the biggest disadvani,.
tage of solar power on the lar'ge
scale. The energy oT -sunlight isr:
spread so thinly that, 'for 'thd
fOreseeable future, it would be .
too expensive to collect it for
power purposea,
But, despite' this fundamental
drawback, there are some labor-
atory experiments aimed at pow-
er. These are the basis for the
hope expressed here that soirie.,
day the cost facter will *be
licked and the sun harneased
directly for power. r.
The Israeli water boiler is
case in point.
It was developed by Israeli
physicits manly to show that it
is possible to reach boiling wa-
ter teinperatures with a flat- '
plate heat collector. Previously,
only a ,focusing` Mirror , or lens
could bring water to a boil,
The Israeli physicists found a
way of improving the effective:
/less of their ',heat cpllectOrs,
which are made of Metal pipes '
attached to a blackened- rnet.aitt
plate and protected from the
wind by a",single or double layer
of glass,' . .1
As a Water healer, lids is an
effective 'device and, it mass
produced, would probably not
cost 'too Much more than con-
ventienal water-heating' equip-
'tient, according to its 'designers.
But, as a generator tit high-
temperature steam for indus-
trial power. the heater again
suffers from the need for large
collecting` areas to gather useful
amounts of power, In this di-
rection, it isr another research
hope that is a long Way from
realization.
But, close by the Israeli ex-
hibit, there Were oilier p'iece's
bt equip-Mitt that illustrated
the Mere immediate prospects
using solar energy.
A row of solar cooker's gleani-
ed brilliantly in the rnidthorn-
ing sun. These were Mainly
parabolic mirrors- of chehP Con-
struction and about two to three
feet in diameter with a pet.,
holding stand at the focus.
An egg was boiling merrily
in the model shown by Dr. Ad-
rian Tarcici from. Lebanon. It
took: just three minutes to start
it boiling in the hot Arizona
tsun.—Thie 'was 'much faster, Dr.
Tarcici, observed, .than the 20
" minute's *a similar' 'demo- ltration
. had taken:.in the cooler cliniate
of Central Park, New York.
tut, "like the smoothly work-
ing Italian solar water pump or
the' model-house heating and
cooling units in nearby exhibits,
.Dr. Taricis cooker, and others
'like it, ''will find their biggest
usefulness in, lands where the
sun is hottest.
Sir Edward and other speak-
ers ranked such use of sun
power as of prime importance
for the underdeveloped areas
that generally lie in hot clie
mates, la
Solan'stoves, for example, if
redticed from the $10 to $45
they'fitriv cost to under $5, eduld
cut the fuel costs that drain
heavily on the small money in,;.
camps of families in these areas.
They could' also eliminate the
use of animal refuse as a sup-
plemental home-cooking fuel
and release it for the more valu-
ableuse as fertilizer for the food
crops,
Hduse cooling using solar
power can also be a big help to
these countries. Sir Edward
`pointed out that working effi-
ciency in hot areas goes up
when cooling-is available, to say
nothing of the advantage of re-
frigeration for preserving food,
as more effective means for do-
ing this with solar units are
worked out.
It takes only the area of a
roof to collect enough solar
power to cool a house during
the hot daytime hours and to
eollect enough energy for stor-
age to operate the cooling sys-
tent during the night, Sir Ed-
ward observed.
Solar pumps, which could re-
place the man-plus-bullock ir-
..rigatien systems. in these ,parts
of the world, ,have their attrac-
tions for underdeveloped areas,
too.
Al,l of these,functions and any •
`Other's that could be' performed
by solar devices, can be served
more effectively by gasoline-
or oil-powered motors, The ad-
vantage Of the ablat units lies
in the• fact.-that they make no
money drain on the country for
I 'their ''operation and can, in
many eases, be'built by native
, craftsmen.
These are the practical uses
of,applierl solar energy that are
already economical, or just one
or two development stages from
being so. Beyond them are the
,brgad,Areems of .harriessilIg the
,sunlight for power..
These,drearns ,are ,based on
such things as the Israeli water
boiler or ..the experlinents that
`haVe hsed, sunlight to break wa-
ter into hydrogen and oxygen
gasea, thus turning this common
,liquAl into a high-grade fuel.
