New Japanese Airport Will Be Cooled With Snow

Starting in 2010, the New Chitose Airport in Hokkaido, Japan will collect snow in the winter to good choice levitra without perscription provide 30% of the terminal building’s cooling needs in the summer.

The snow will be covered by heat-insulating materials, which should retain about 45% of the snow collected. The remaining snow will then be used to chill the liquid of the building’s cooling system. According to Japan Today, the practice could result in a 2,100 ton reduction in CO2 emissions per year.

This process isn’t new to Hokkaido, Japan’s northernmost island, which receives between 20 and 30 feet of snowfall a year. The island has been experimenting with cooling systems using their icy resource since 1998 and has already installed systems in smaller public buildings.

We need more innovative thinking like this in America!

Brilliant concept

I really like this idea... I wish more countries would start up with this kind of facility... Imagine the buy levitra cheap us amount of reduction in emissions... Certainly a good technique!

How about old fashioned ice houses?

I guess at the airport they have to plow the snow anyway. For a city near a water source (river), how about making a large insulated ditch with removable cover-- fill it in the winter and viagra and women let it freeze, then use it for cooling in the summer.

the effect on the water cycle in that environment? It sounds like a good idea, I just have to wonder. Does the reduction in CO2 emissions outweigh any other potential environmental hazards? (I am not coming from an educated position on this one - just mere speculation.)

This is the same principle/concept utilized in the southwest of utilizing large chillers to create ice at night (when electricity rates are "off-peak"), and then using that ice during the tramadol in us day to www.barefootfoundation.com provide cooling to a building vs. running that chiller during the day (when electricity rates are at "peak"). But, certainly, the snow is viagra generic now relatively "free". It does cost to gass up the trucks to plow it to concentrate the amount of snow pack, and there's emmissions that go with that. So, is it really "green"? We won't know for awhile.

the article states this system will save more than 2100 tons of CO2 per year.
a long haul flight typically results in approx 1 tonne of co2 per person.
lets say each flight carries 200 people. the annual environmental benefit of this cooling system will be wiped out within a few hours.
maybe more high speed rail would be more environmentally sound.

I wonder how dense the snow could collect in a system like this. Maybe adding a small amount of water to the system could form a more efficient block of ice (maybe too heavy?) I dunno. Just thinking out loud.
The runoff in the summer could be used for maintaining landscaping, etc.

Everything old is new again -

The Famous author John Mcphee ("Comming Into the Country" among others) wrote about this in one of his books in the early 1980's. There was a system up and running in New Jersey, I believe at Princeton. The snow was made during the winter with snow guns (much less energy use than mechanical chillers) and then covered for use in the summer. I still have the book at home, I believe it was "The Deltoid Pumpkin Seed". Of course, you do need some land area. The snow guns today use less energy then they did back then, so the levitra to order technology should be even more favorable

Wow, that's possible? Hope every other countries would follow this trail. (for those with snow, of course) smilies/wink.gif

The Japanese already have high speed rail. They still need aircraft to travel from one island to buy ultram without rx another or to other countries. Building tunnels or bridges that could replace this is simply not possible with current technology.
