This week at our latest Meteek Workshop event we rolled out a vision for establishing Duluth as a "Dark Sky" city. We hosted a presentation by Tom Nelson and Eric Norland from the Arrowhead Astronomical Society about the Milky Way and light pollution, and talked about a vision for making Duluth a city where more stars are visible.

Here is an info sheet we generated

Besides the presentation, we had live DJ music from MAR (http://soundcloud.com/marmusics) and a new show up in the gallery, mandalas from Cynthia Lapp. We were having so much fun we forgot to take any photographs of the event. Below are some of the gallery. Enjoy!

ASHRAE Show and Millennium Park

Posted by Cynthia Lapp

This week we had the pleasure of attending the ASHRAE (American Society of Heating, Refrigeration and Air-Conditioning Engineers) winter show in Chicago, North America's largest heating and cooling show. Lots to see, and lots of innovation going on.

We had fun scootering around the city, looking at materials and building techniques. In Millennium Park, we saw frost patterns on the Cloud Gate sculpture (the "Bean") one morning, then had the opportunity to speak with one of the builders from the firm that constructed the sculpture and did the finishing work. He was taking out a scratched graffitti tag.

He recounted the long, slow process of constructing the sculpture and taking the stainless steel panels to a seamless mirror finish. He said the first time they saw the frost patterns, they thought the whole mirror finish had somehow gone wrong. They were relieved when the air temperature warmed and all the lines vanished.
