Jim Scott of Talkeetna and Lasse Holmes of Homer have arrived to teach about heating. Jim will take the first half of tomorrow (8am-noon) to instruct while constructing a 30 gallon hot water heater which operates from sun radiation rather than electricity. The second half of the day, Lasse will instruct on construction of two styles of wood burning mass rocket stoves. Also joining will be  Gary Currington of Fairbanks, who will demonstrate mobile rocket stove designs he has invented.  Location of both events is at the UAF Cooperative Extension Tanana District Office.    If you have not yet registered and are interested, contact Art at 322-2309.
