The Core of the Sun enhancing her knowledge of chili peppers by extending an invitation to his farm. There, she sampled and grew an assortment of peppers. Working with chili peppers allowed Sinisalo to understand factors such as the Scoville rating which is determined by capsaicinoids. The Scoville scale measures the spiciness (heat) of the pepper. One can explore the Scoville ratings, health benefits, and growing techniques of peppers on Kilpinen's website In the Core of the Sun's Afterword, Sinisalo describes the Transcendental Capsaicinophilic Society as “ a real, though somewhat tongue-in-cheek, group that can be found on the Internet.” A quick Google search reveals
Heat pump must be colder in temperature than the space to be heated. Most commonly, heat pumps draw heat from the air (outside or inside air) or from the ground (groundwater or soil). The heat drawn from ground-sourced systems is in most cases stored solar heat, and it should not be confused with direct geothermal heating, though the latter will contribute in some small measure to all heat in the ground. True geothermal heat, when used for heating, requires a circulation pump but no heat pump, since for this technology the ground temperature is higher than that of the space that is
