Sustainable Living Tips by Lee Leffler

My daughter and I will have a booth at the Holiday Trade Fair in Fairfield, Iowa on Saturday, with a totally sustainable gift: Polar Bear Donation Certificates. Customers can make a donation in their friend’s name and get a certificate to give to them. This booth is for the Natural Resources Defense Council, and the polar bears, whose habitat is greatly threatened by global warming. Did you know some are drowning because there is too much distance between icebergs? I hope you can come! Please tell your friends. If you cannot come, you can still make a donation and get a certificate online.

On Saturday December 5, the Dharma Foundation will hold a Holiday Trade Fair at the Field House on the MUM campus, next to MSAE, from 10-4. Admission is free. There will be local artisans, local companies and lots of incredible food!

M.U.M. Organic Farm

The Maharishi University of Management Organic Farm in Fairfield, Iowa, has received a $13,750 grant from the Leopold Center for Sustainable Agriculture to study growing vegetables in large gutter-connect greenhouses in winter without added heat.

Not heating the greenhouse will reduce the farm’s fossil fuel consumption by about 88%. “This is an innovative study and a significant step in making the M.U.M. Farm and the University more sustainable,” said Steve McLaskey, assistant professor of biology and agriculture and director of the farm.

On the campus of Maharishi University of Managment, the new storage building by the Golden Dome Market is now being heated and cooled with geothermal technology as part of a pilot project to install geothermal systems in additional campus buildings.

Geothermal technology involves drilling holes in the ground, inserting loops of pipes, then circulating water through the pipes. Since the ground in this region is a constant 55 degrees Fahrenheit, heat can be either extracted or rejected as it is circulated through the pipes, providing winter heating and summer cooling.

The University is leasing a special rig to drill holes horizontally, 15 feet underground. The drill can run under lawns, parking lots, and other terrain, without disturbing the landscape. When the drill has gone far enough (usually several hundred feet), it is sent to the surface. A loop of polyethylene pipe is attached to the drill head, and the drill slowly retreats back through the hole, bringing the pipe with it. Soon, the pipe is underground, ready to be filled with water and connected to a ground source heat pump that uses only a small amount of electricity (about a quarter of the amount used by a small space heater).
