Using a very old idea – the cooling power of the evaporation of water – a small Indian group has released plans for a very inexpensive but effective way to keep food cool and fresh – refrigeration without any power source whatsoever!
The bamboo iceless refrigerator is a low cost device that can be used to store food items. It preserves the food longer, and keeps it cool. This fridge can be used to store vegetables, fruits or even keep your beers cold. Detailed instructions at the end of this article
When the temperature of the air is high, water will evaporate without boiling first. When it does so, in this bamboo based contraption, it removes heat from the enclosed cooling compartment to keep food and drinks cool on the hottest days. Even better, the only energy it requires is to be topped up with water every so often!
I’ve had a cold beer from a modified version of this contraption – using a discarded fridge in a desert area where the electricity no longer functioned – and can attest to how well it works (and how good that beer tasted!). Of course you can also use the evaporative cooling potential of water to keep yourself cool, for example with this vest from amazon in the ad below (article continues after).
The bamboo refrigerator is a bamboo box with a loose fitting lid. Both the box and the lid are covered with jute cloth. The box is then kept over a tray containing water in such a way that the jute cloth of the box is in touch with water. Any material desired to be preserved can be kept inside the box and covered with the lid. The box and the lid are then dampened with clean water. The capillarity of the jute cloth will keep absorbing water and remain moist. The vaporization of the water on jute cloth will keep the temperature inside the box low.
The design and working of the bamboo refrigerator is simple and does not require any engineering skills to make. This is a perfect technology for people who want to live far off grid for short or long periods of time, in some comfort, and without the expense of a full on refrigerator.

Off-Grid.net is investigating the Utility companies --power, water and waste.
Do the water companies conceal their knowledge of the pollution of the water supply? Do the power companies conceal the wasted energy inside the system, and their excessive profits?
We need help to find the smoking guns: memos, SEC filings,confidential legal advice internal emails..... send to firstname.lastname@example.org. Anonymity guaranteed
Can you handle a video camera? Or a cellphone camera that can upload to our youtube channel?
We are looking for people who currently live off-grid anywhere in the world, and for people who want to live off-grid and are about to do so. This might be in a community or an individual situation
Please send us your videos and photos - you can upload videos on off-grid.net/videos - or feel free to write about yourself for the web site. Contact email@example.com
