It only happens once every few years:
a brackish river in New Jersey
freezes over, and the iceboats
come out. It's happening all over the Northeast, where an unusually cold winter is welcomed with delight by aficionados of this sport
. Lightly constructed, beautiful, and fast
(the record stands at 84 miles an hour propelled by wind alone), iceboats provide a winter thrill ride like none other
or ice yachting
has thrived in pockets of North America
since the nineteenth century. When conditions are right, see them sailing and racing
, on the Hudson
, in Maine
, Prince Edward Island
. and wherever else "hard-water sailors"

is an animated short about the daily life of people living in a windy area who seem helplessly exposed
to the weather. However, the inhabitants have learned to deal with their difficult living conditions.
The wind creates a natural system for living.

On June 11th, 2013, in the wee hours of an early summer night in Nebraska, the temperature shot from 73°F to 99°F in the space of minutes
, accompanied by 50MPH winds. The cause of this weather oddity was the poorly understood Heat Burst
, a phenomenon that sometimes occurs as thunderstorms die out
, usually late at night. The temprature rise can be so extreme that it has been imaged from space
, and there are unconfirmed stories
of heat so extreme that crops were cooked in the fields where they grew, and paint blistered on houses and vehicles. Once believed to be a very rare
event, with the advent of personal weather stations, science may find they are more frequent than was previously believed.

“Uncle Vincenzo,” implored the businessman, Angelo Salvatore, using a term of affection for the alleged head of Sicily’s Gimbellina crime family, 79-year-old Vincenzo Funari. According to a transcript of their wiretapped conversation, Salvatore continued: “For the love of our sons, renewable energy is important. . . . It’s a business we can live on

Three years ago, a question was posed to two Internet forums
. Could you build a wind powered vehicle that could travel downwind, faster than the wind? The lines were quickly drawn and the battle was on, including here on the blue
. It took nearly two years for the debate to be settled, and on July 2, 2010, what seemed impossible was achieved
. The answer is yes
, you can

California's calm before the storm.
It's just rain, right? Well, the meteorologists are publicly talking about a potentially epic
storm that could trigger major flooding and mudslides
, especially in areas effected by the state's widespread fires of the past few years. More ominously, though, is this internal email from CAL FIRE Division Chief Bob Wallen
, which talks of the potential for "multiple large and powerful storm systems" with "a tremendous amount of precipitation . . . Much of NorCal is likely to see 5-10 inches in the lowlands, with 10-20 inches in orographically-favored areas. Most of SoCal will see 3-6 inches at lower elevations, with perhaps triple that amount in favored areas", with the potential for a massive snowfall, gusts in the 100-200 mph range in the high Sierras, possibly followed by plentiful warm rains that could melt the snow and cause massive flooding statewide. "The next 2-3 weeks (at least) are likely to be more active across California than any other 2-3 week period in recent memory."

Forecast calls for cold and warm.
On January 22, 1943 in Spearfish, SD: The temperature rose 49 degrees in two minutes, from – 4 to 45; later the same morning, it dropped 60 degrees in 27 minutes, from 56° to - 4°. Plate glass windows cracked as a result of the wild fluctuation in temperatures caused by Chinook winds. The greatest 24- hour U.S. temperature difference in one place was set January 23- 24, 1916, in Browning, MT, at 100 degrees when it went from a low of -56° to a high of 44°.*
is one way it's been described, old tales too.
. It's a seasonal wind, like the Mistral.
There is some overlap in the definitions but the Chinook can safely be labeled a Foehn wind. A Foehn wind is "a generic term for warm strong and often very dry downslope wind(s) that descend in the lee of a mountain barrier". That is the one illustrated above. My favorite wind though, is the katabatic. A downhill wind. Cold and dense
it blows here on Earth
especially in the Antarctic
, and there on Mars
too. (page 9 of 14.) [more inside]

-- oilman T. Boone Pickens has a plan to reduce America's oil dependency problem: exploit the country's massive windpower potential for domestic energy, replacing natural gas, and then use natural gas to power cars instead of foreign oil. Some problems
with the plan.

(Farsi) or barjeels
(Arabic) are windcatchers
that work as low-tech air conditioners. The city of Yazd, Iran
is probably best known for them. Badgirs are built so that they can be opened to catch the wind from different directions, the air is then cooled as it travels down the tower, and in turn cools the rooms below. When there is no wind, air in the tower is heated and rises, which draws cooler air from the courtyard into the house. (There is no URL to link to for the search result for “badgir” on Encyclopaedia Iranica
, but I recommend checking out their definition and diagrams even though you’ll have to go through three different PDF pages.) Badgirs have been around in some form “since the New Kingdom (1500- 300 BC) in Egypt”, but global warming might make them ineffective.(scroll down to #16-#18)
Variations, such as malqafs
, can be found from Egypt
. You can get a modern one
for your own house. You can win an award
shaped like one for advancements in sustainable development.
Or you could just stay in the Fairmont Dubai Hotel which is shaped like a huge badgir
. So even after all this, I still don't know what those sticks sticking out of the sides are for.
