NXP Speakers in Alaska
Mount McKinley, Alaska, is the highest mountain in the North American Continent at 6193m. The Eskimos called
it "Denali" which means "The Great One". It is known as the coldest mountain in the world, due to
its height and its proximity to the North Pole. Temperatures of -40 deg C are normal during the climbing season
of May and June.
During the "German Denali Expedition 2008" you see here pictures of the expedition leader, Richard Forsyth, using
an NXP speaker. Richard said: "The NXP speaker provided a great improvement to our social life on the mountain.
Instead of each climber listening to his own iPod or MP3 player in isolation, we were able to share our listening."
The speaker was powered with rechargeable AAA batteries recharged by a solar cell. Due to the high latitude, there
is sunlight almost 24 hours/day, and therefore solar cells provide an ideal source of power. Because of the high efficiency
of the NXP speaker the solar cell was sufficient to provide unlimited playing time.
