Architecture students (l-r) David Dill, Chris Melvin, Kevin Hall, and John Hooten demonstrate passive heating principles in a solar heater they built recently for a class research project. With a little help from the sun, their device can heat 1,000 cubic inches of air up to 240 degrees in about an hour.
