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.eating your home with an active solar energy system can significantly reduce your fuel bills in the winter. A solar heating system will also reduce the amount of air pollution and greenhouse gases that result from your use of fossil fuels for heating or generating the electricity.
