PowerFilm Rollable Solar Charger Review

 

I recently had a chance to review the R-14 Rollable Solar Charger made by PowerFilm.  It comes in a roll and is very lightweight.  When unrolled it measures 14.4 x 42 inches.  It come with a Velcro strap to keep it rolled up when in storage.  Included with the panel is a 12 volt female cigarette light adapter and a 15 ft. extension cord with battery terminal connectors.

PowerFilm solar panels are made of thin film on plastic that are really rollable.  When rolled it is about 4 inches in diameter.  PowerFilm is made of silicon, a natural resource in abundant supply and is Cadmium Free.…

Solar Oven Cooking Tips

This is a solar oven, I built out of junk. I found in my yard. The ground was damp so i set it on a old tire. It worked well.

Cooking with a solar oven is different than cooking with your kitchen range.  For instance most kitchen ranges cook from the bottom up.  A box type solar oven cooks from the top down.  This is one of the reasons you need to experiment with your solar oven.

If you are cooking bread or muffins, try putting a heat sink under the pan.  This will help make sure they are not too moist on the bottom. …

Getting Rid of Insect Infestations in Your Food

If you are in an emergency situation and have no power, what do you do when you open some of your food and find it  infested with insects.  An easy way to destroy the infestation is to spread the food out on a shallow pan and place it in your solar oven for about an hour.  This will kill the insects and lava.  Try and keep the temperature at about 200 degrees.  Remove as many bugs as possible and use the food in a normal manner.

Emergency Radios can Save Your Life

Today I am sitting here listening to my emergency radio.  After trying several, the one I own is the Kaito Voyager KA500.   This a perfect radio for everyday use, emergencies and disasters, it comes with all the features that you need in any emergency situation.

Right now the radio is running on solar power.  The radio has several alternate power sources: solar, hand crank, batteries, USB cable, a built-in rechargeable battery pack and an AC adapter.  I have never put batteries in the radio.  I have had it for years and have always ran it off solar.  The solar works well during the day and it charges the built-in battery for nights. …

More on Solar Ovens

Solar ovens are a great way to cook; they are efficient, clean and easy to use.  In the hot summer the heat stays outside.  They work well in the winter as long as the sun is shining. The ambient air temperature doesn’t seem to matter much, as long as the ovens are well insulated from the cold ground or snow and in bright sunlight.

The one in the picture on the right is an old metal box I found and lined with 2 inch foil covered styrofoam insulation and a sheet of plexiglass for a top cover. It works quite well. …

Solar Oven Cooking

A simple and inexpensive method of outdoor cooking is the solar oven.  In most locations they can be used though out the year.  A friend of mine in Wyoming has used his when it was sitting on 4 feet of snow.  As long as the sun is out you can cook.

There are many designs for solar ovens, some are better than others.  You can buy one or make it yourself.  I have seen them sell for 200 – 300 dollars or you can make one for next to nothing.  The better ones are more efficient and will reach hotter temperatures.…

Sodis an inexpensive method of water purification

Solar water disinfection, also known as SODIS is a free method of disinfecting water using only sunlight and plastic PET bottles. SODIS is recommended by the World Health Organization (not my favorite people) as a viable method for household water treatment and safe storage.  SODIS is in use in many third world countries.

To use Sodis you fill Pet plastic bottles with contaminated water, and then lay them in the sun.  The best place is a corrugated metal roof.  Be sure to shake your bottles before placing in sun.  Pet plastic bottles can be identified by the recycling number 1, usually located on the bottom.   …
