The pot-in-pot refrigerator or zeer (Arabic: الزير) is a refrigeration device which keeps food cool without electricity by using evaporative cooling. A porous outer earthenware pot, lined with wet sand, contains an inner pot (which can be glazed to prevent penetration by the liquid) within which the food is placed. The evaporation of the outer liquid draws heat from the inner pot.Although the principle behind the device has been known for centuries, one modern device was developed by lecturer Mohammed Bah Abba for use in modern Nigeria.
The technique of using evaporative cooling with clay pots for food preservation was re-discovered by Mohammed Bah Abba, a Nigerian teacher from a family of pot-makers, who patented a pot-in-pot refrigerator in 1995 to help Sudanese families preserve food. Bah Abba was awarded the $75,000 Rolex Award for Enterprise in 2000 and the World Shell Award for Sustainable Development in 2001 for its development.

60 watt light bulbs that are free energy
I have made this a separate post now because this idea of low tech missionaries seems like a good one. I didn't have place for it before. So I think this idea and others posted under "Low Tech Missionaries" will be a good reference for Catholic Missionaries.
Here is another low tech idea for lighting:

Why Is Walking in the Woods So Good for You?
If you’ve ever gone for a walk in the woods, then you know the wonder of the feeling you get from it. But did you know that besides giving you a good feeling, walking in the woods is actually good for you? The Japanese call it shinrin-yoku. Translated, it literally means “forest bathing.” And now scientists have found physiological and psychological benefits from forest bathing.
They give a number of factors that contribute to the good health benefits of that walk in the woods (or park), including cleaner air, the relative quietness as compared to city life, and just the chance to separate yourself from the crowds. But researchers at Japan’s Nippon Medical School are offering another theory as to why the walk works: and it has to do with the essential oils that trees naturally emit into the air.

What are Essential Fatty Acids
Essential fatty acids come from fish and plant oils and these are the good fats your body needs for survival. They are the polyunsaturated and monounsaturated fats referred to as the Omega fatty acids: Omega-3, Omega-6 and Omega-9.
The human body does not manufacture Omega-3 and Omega-6 fatty acids and therefore these must be obtained from the foods we eat.
Omega-9 can be created in the human body from unsaturated fat such as olive oil. Some Omega-9s are common components of animal and vegetable oil.
Omega-3 is probably the best known of the essential fatty acids. However, we need all three omega fatty acids in combination to obtain balanced optimal levels of each for our good health.

THE LOST SCIENCE OF MONEY - A SOLUTION TO THE STATES’ FISCAL CRISES
http://www.monetary.org/speech-at-the-u-s-treasury-dec-4-2003/2010/12
Stephen Zarlenga’s speech at the U.S. Treasury (Dec. 4, 2003)
On December 23, 2010, in Research & Articles, by AMI
I thank the US Treasury for inviting me. It’s a great honor and opportunity to bring the research results of the American Monetary Institute to your attention, which are relevant to the developing fiscal crises faced by several states. Part of our 501c3 mission statement is to do just that.
The fiscal problem has its roots in the structure and control of our monetary system and I intend to show how that structure has ultimately been based on a false or inadequate concept of the nature of money.
THE PROBLEM IS THAT MONEY HAS NOT BEEN ACCURATELY DEFINED
Perhaps the chief failure of economics is its inability, from Adam Smith to the present to define or discover a concept of money consistent with logic and history. Economists rarely define money, assuming an understanding of it.
It’s still being argued whether the nature of money is a concrete power, embodied in a commodity like gold; or whether it’s a credit/debit issued by private banks. Does its value come from the material of which it’s made? Or is it, as we have concluded, an abstract social power – an institution of the law, having value because its accepted in exchanges due to the sponsorship of government?
