Kermit the Frog might think it's only natural to be green during
the holiday season, and maybe you can too by making a couple of
easy changes to reduce spending and waste. For many people the
holidays signify stress and over-spending. This year...
Experience the Thrill of Eagle Watching
"Above all other birds it is the soaring eagle, with its size and weight, that gives the most abiding impression of power and purpose in the air," declared Edwin Way Teale in Atlantic Monthly in 1957. Unique to North America and revered for its...
Global Dumbing?
I am beginning to wonder if scientists have been getting it all round. All this time, people have been worried about the Ozone, a giant asteroid, or some breakout of a bio-hazardous agent by a terrorist organization being the doom of mankind. We...
Secrets of the 200 MPG Carburetor
Dear Fellow Car Enthusiast:
Thanks for requesting this report on the "200 MPG Carburetor." It should inspire you. It may make you angry. It may answer some of your questions, while raising a few more. For example.
These questions have been...
Shedding Light on Cheaper Solar Energy
Renewable sources of energy are the key to solving two of the worlds most pressing yet seemingly irreconcilable problems. On the one hand the developing world needs vastly to increase access to affordable energy because, at present, 1.6 billion...

Solar Cooling - Air-Conditioning From the Sun
At first glance, solar cooling looks like an oxymoron. However,
the same energy that can provide heat in the wintertime can also
provide cooling during the summer.
Several passive cooling systems have been developed and tested.
At their simplest, they rely on a coolant that absorbs and
dissipates heat from the house. This could be a pool of water on
the rooftop which absorbs seat from the inside of the house as
it evaporates on exposure to the sun.
More sophisticated passive solar cooling systems have a solar
collector which is shaded during the daytime. A storage medium
collects heat during the day and dissipates it at night by
exposing the solar collector to the cool night air.
Since the solar collector must be shaded, a retractable awning
or overhang extension can be installed. Since the system can be
reversed in the winter months, it is important that the solar
collector can be exposed to sunshine if needed.
Solar panels can also be used to operate traditional air
conditioners. As it
U.S. Is A Spicier Nation (Literally) Since 1970s Americans' spice consumption has grown almost three times as fast as the population in recent decades. Much of that growth is due to the country's changing demographics. Now, flavors that were once exotic and rare are found on the shelves in many groceries.
happens, the periods of intense heat
correspond to the periods of peak electricity production from
photovoltaic cells. As long as you have solar panels which
generate sufficient to electricity, you can operate air
conditioners at no cost.
Solar cooling that does not take advantage of high technology is
another possibility. The Romans used a system of running water
to cool down exterior walls of their houses. The heat of the sun
causes the water to evaporate and dissipate the heat within the
house. This kind of system can be used on walls or on rooftops.
Heating and cooling are two of the biggest expenses for most
households. Using solar energy to reduce this expense makes
sense financially as well as ecologically. The less dependent we
are on fossil fuels for heating and cooling the cleaner the
environment will be.
