U of MN solar car, Centaurus, ready for 2008 race from Texas to Canada

New Vehicle, Centaurus, to replace Borealis III: Borealis III, the 7th generation UMN solar car, with the Tin Man in front of the Mechanical Engineering building, U of MN. The Borealis 3 won 2nd place in the 2005 North American Solar Challenge (from Texas to Canada).
Courtesy Adem Rudin The University of Minnesota Solar Vehicle Project team provided a sneak preview of its newest car, Centaurus. The U of MN team placed 2nd in the 2005 North American Solar Challenge. The 2008 NASC will take place on July 13-22, 2008, on a route between Dallas, Texas and Calgary, Alberta.

"As many of the top cars were bumping up against the 65 mph (105 km/h) race speed limit in the 2005 event, race rules were changed in order to improve safety and limit performance. Open class cars are now only allowed 6 square meters of active cell area, and upright seating is required for both open and stock class cars."

sacred pipestoneHello do you know what pipestone is.
I give you a chance to work with sacred pipestone?

My name: Keith Nelson a member of White Earth Indian reservation , i have quarry site # 28 in the national monument in Pipestone, MN.

You are looking at sacred pipestone.

We the Native American's are the only ones that can get this stone from the quarries , I know there are other people out here selling stone from other states and maybe down the road from the sacred quarries....

Let me tell you it is not the same.

My ancestor's have been getting the stone in the traditional manner for century's ....

Not using a back-hoe or bob-cat but using bare hands and hand tools along with the knowledge from our elders.

We continue to traditionally quarry not only because that is the only way the stone can be quarried at the national monument but we will continue to do it this way.

Ty gitche monedo for taking me to the sacred place to share a little bit of what most people don't know much about.
