The Lincoln Land Community College Green Center is holding a Do-it-Yourself Solar Hot Air Collector workshop on Saturday, Oct. 22. The workshop is being held from 9 a.m.. to 4 p.m., and registrations are now being accepted.

During this daylong class, participants will learn how to build and install their own low-cost solar hot air collector, which can be built in one weekend for under $400 using locally available materials. One 4x8-foot panel can mount on a south wall of their house, garage or work shed to provide daytime heat on sunny days for up to 500 square feet of floor area. During class, participants will work as a team to construct a collector. Hand tools and all supplies will be provided; however, participants are welcome to bring their favorite hand tools.

Cost is $50 per person or $80 per couple. Registration deadline is Thursday, Oct. 20 at 5 p.m. To register, go to llcc.edu/greencenter or call 786-2434.
