Cob Art & Earth Architecture

Abey & Smallcombe

Oh, this is exciting! Never have I seen such wonderful earthen sculpture. Cob art, ecological buildings, colorful earthen floor tiles, educational programs. This dynamic team of artists in Drewsteignton, UK will knock your socks off. Jacki Abey and Jill Smallcombe teamed up in 2000. Jackie has trained at Taunton Art School and is a painter, while Jill has a degree in sculpture from Bath Academy and works as a interior designer, teacher and sculptor.

An object with special powers to metaphysically tune the mystical material – cob. An electronic device that samples the ratio of water, clay, sand and straw. Then chimes when the mix is suitable for building.

…or NOT.

St. Olaf, Making Green Strides

dreaming of clean energy with two 1.65 megawatt turbines

Soon that lonely turbine wont be so lonely anymore! St. Olaf has started planting the roots for yet another 1.65-megawatt wind turbine among the soybeans and corn. This power will be used directly by St. Olaf. Providing an estimated 30% of the colleges total energy needs.
