Botanical name: Myristica fragrans Like many other spices, nutmeg is one of those fragrant additions to food that brings a little kick of warmth and curious complexity that, once tasted in a dish, can't be done without.ike many other spices, nutmeg is one of those fragrant additions to food that brings a little kick of warmth and curious complexity that, once tasted in a dish, can't be done without.
Heat loss. The loss of heat from a solar oven is described by the Second Law of Thermodynamics, which explains how heat travels from hot to cold. Heat loss is a combination of conduction, radiation, and convection.Heat is lost from the solar oven by conduction, when the heat travels through the molecules of the physical box to the outside air [ Mark Aalfs ].Radiation is also a factor in heat loss, when hot air radiates through the glass lid.eat loss is a combination of conduction, radiation, and convection.

Active solar heating systems use solar energy to heat a fluid -- either liquid or air -- and then transfer the solar heat directly to the interior space or to a storage system for later use. If the solar system cannot provide adequate space heating, an auxiliary or back-up system provides the additional heat. Liquid systems are more often used when storage is included, and are well suited for radiant heating systems, boilers with hot water radiators, and even absorption heat pumps and coolers.
