this portable solar oven, which gets hot
enough to cook food and even melt wax for
candle making.
By Miles Stair
A
half century ago, many farmsteads had
specific tools for specific purposes. It was
called efficiency. Most of those tools have
disappeared, in many cases along with the
reason for them. Now, we must often build our
own specialized equipment. Fortunately, it is
neither hard nor expensive, and the end
result is vastly increased utility and
efficiency.
In
hard times,
canning fruit juices will be necessary.
Commercial products might not be available
nor their purity reliably. Home canned fruit
juice retains the vitamins and minerals, and
thus health is more easily maintained. How
soon has modern society forgotten the cause
of rickets and scurvy!
To
can large quantities of juice, one needs to
have a safe, fast, food chopper, a filter
bucket (on left, second photo below), a
sediment bucket (on right, second photo
below), and ideally a bottom draw bottling
tank (tall tank in center) and a proper valve
(right photo below), may be heated over
a kerosene stove. With this equipment, dozens
of quarts of fruit juices may be easily and
safely canned in a day.

Large
quantities of applesauce and berry juice
can be processed with the use of a
Squeezo strainer and the proper filter
cone. Apples need only be chopped
into quarters with a home made chopper
(left, above), boiled for 15 minutes,
cooled, then run through the Squeezo
strainer - the peels come out the end,
separated from the sauce. The applesauce
can then be kept hot in the bottling tank
over a kerosene stove (3rd and 4th photos
above), and poured directly from the
bottling tank directly into pre-heated
canning jars. |
Processing and canning large quantities
of foods puts a strain on any modern kitchen
- they were not designed for such purposes.
It is much more convenient to do the work
where the area can be hosed down and spills
or messes don't damage delicate modern floors
or counters. It may all be done outside on a
patio or in a garage, using kerosene cookers
as the heat source. Kerosene stoves are
extremely reliable and inexpensive to use,
plus they provide a marvelous freedom from
the electric or natural gas grid systems. But
the kerosene cookers are not strong enough to
support heavy canners. The best idea is to
build a sturdy, steel
cooking stand which fits over the
kerosene stove and supports all the weight
itself.
To
protect our electronic equipment,
Faraday cages stop electromagnetic pulse
(EMP) resulting from nuclear explosions or
Coronal Mass Ejections (CME's), also known as
solar flares. It is very easy to make Faraday
cages from aluminum foil or sheets of Mylar,
store the equipment in them, and know that
when we need that equipment it will actually
work.
Charging or operating small appliances
from a 12 volt RV battery is possible using a
home built pig tail with battery post clamps
as an external cigarette lighter socket
(bottom of photo). Then a small
battery adaptor (top of photo), such as a
Recotron AD 61, can be plugged into the
lighter socket and the proper voltage
selected to run or recharge many small
appliances.
To
keep ourselves in life saving fresh water, we
can build water collection, storage and
delivery systems for our homes, as detailed
in my booklet
"Rainwater Collection." But what of our
domestic livestock and pets? They too need a
reliable, independent source of water, and it
is relatively easy to build a
gravity flow chicken or stock watering
system for them.
Solar ovens or melters are extremely
efficient and easy to use for about 7 months
a year - spring through autumn. My solar oven
is used mostly to melt wax for making
candles, but by removing the wax melting tray
it can also cook food just like a slow cooker
and even bake bread. It reaches 220 F. within
2 hours of placement toward the sun, and if
turned and oriented toward the sun again,
will ultimately reach about 300 F - enough to
bake bread. Solar ovens are totally passive,
last for many years, and can be used without
attracting attention from passers by. Anyone
with carpentry skills can make a portable
solar oven, and even if used for nothing
other than making candles, they are extremely
worthwhile.
