Tips & Warnings. 1  Use an epoxy resin spray on cured pieces to cover indents or other imperfections. 2  You can also buff out imperfections with plastic polish and a buffing stick. 3  If air bubbles form in the mold, blow gently on them to pop them. 4  Wear gloves and work in a well-ventilated room.f it does show an indentation, leave to cure for an additional 1 to 2 days. Turn the mold upside down and lightly tap the back until the the resin piece emerges. Spread the resin pieces out on a sheet of wax paper and leave them to finish curing for an additional 12 to 24 hours before buffing or mounting.
1.0 Passive Solar Design Introduction. Solar energy is a radiant heat source that causes natural processes upon which all life depends. Some of the natural processes can be managed through building design in a manner that helps heat and cool the building. The basic natural processes that are used in passive solar energy are the thermal energy flows associated with radiation, conduction, and natural convection.
Solar energy is energy which is created from sunlight, or heat from the sun. Solar power is captured when energy from the sun is converted into electricity or used to heat air, water, or other fluids.There are currently two main types of solar energy technologies:1  solar thermal: these systems convert sunlight into thermal energy (heat). 2  Most solar thermal systems use solar energy for space heating or to heat water (such as in a solar hot water system). Most solar thermal systems use solar energy for space heating or to heat water (such as in a solar hot water system). 2  However this heat energy can be used to drive a refrigeration cycle to provide for solar based cooling.
