REFRIGERATE FOODS WITHOUT USING ELECTRICITY

This mode of refrigeration goes back at least 5000 years.
It uses 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. The device can be used to cool any substance.
Have any of you tried this?

How To Store Your Garlic, Onions And Shallots So They Can Last For Months

   
INSTRUCTIONS
 
1. Make sure onions, garlic etc are firm and blemish free.
2. Use brown lunch paper bags.
3. Hole punch.
4. Paper clips for holding bags closed.

 HOW TO MAKE
 
1. Punch the bags. You can do this any way you wish, even randomly all about the upper half of the bags. Typically holes are punched by folding the bag a few times and then punching in a row, spacing the punches an inch or so apart. Another method would be to fold the bag in half lengthwise, punch along one edge, flip the folded bag over and punch along the other edge, approximately 1" between punches. It by no means needs to be perfect, simply punch holes for ventilation. The result is multiple rows of holes.

2. Fill the bag up to half full (just below or at first punched holes), fold over the top, label it and paper clip it to hold the top down."

HOW LONG TO NAP FOR THE BIGGEST BRAIN BENEFITS

Taking a nap, we've seen time and again, is like rebooting your brain. But napping may be as much of an art as it is a science. Scientists offer recommendations for planning your perfect nap, including how long to nap and when.P

The sleep experts in the article say a 10-to-20-minute power nap gives you the best "bang for your buck," but depending on what you want the nap to do for you, other durations might be ideal:

For a quick boost of alertness, experts say a 10-to-20-minute power nap is adequate for getting back to work in a pinch.

For cognitive memory processing, however, a 60-minute nap may do more good, Dr. Mednick said. Including slow-wave sleep helps with remembering facts, places and faces. The downside: some grogginess upon waking.

Finally, the 90-minute nap will likely involve a full cycle of sleep, which aids creativity and emotional and procedural memory, such as learning how to ride a bike. Waking up after REM sleep usually means a minimal amount of sleep inertia, Dr. Mednick said.P

In addition to those recommendations, one surprising suggestion is to sit slightly upright during your nap, because it will help you avoid a deep sleep. And if you find yourself dreaming during your power naps, it may be a sign you're sleep deprived. While you're planning your nap, don't forget to time it during the right time of day as well.

Transport - The Bicycle

A World of Unconventional Fuels

From VOA Learning English, this is the Economics Report.The growth of natural gas and oil production in the United States has changed experts' predictions about energy worldwide. Recently, delegates at a conference in Texas spoke of a world increasingly powered by what they call unconventional fuels. By this, they mean fuels that are not petroleum. 

The United States is increasing its natural gas production. But the biggest energy user, transportation, still depends largely on oil. Daniel Akerson is the chairman of General Motors. He says offering home natural gas fueling stations might help. But he says that is not likely to happen until the United States supports the creation of far more fueling stations nationwide.Cars and trucks powered by natural gas are costly. 

That is why John Felmy of the American Petroleum Institute says any change has to start with large commercial vehicles. He says family-sized vehicles would cost too much compared to other electric or gas-powered ones. He thinks it would be wise to suggest the export of liquefied natural gas as a way for producers to expand their business. John Felmy says such exports would cut the United States' trade deficit and create more jobs. Yet he believes they would have only a small effect on the price most people pay. 

Energy officials from many countries wanted to learn how they could expand their own natural gas production at the conference in Houston. For many nations, this is a way to fight poverty. Arsenio Mabote is chairman of Mozambique's National Petroleum Institute. He says energy resources can be used to generate electricity and that brings development.
