What are some more forms of kinetic or potential energy?
Energy from the sun
1000 Watts/m2 at the earth’s surface !!!!!
Energy as a result of the flow of charged particles called electrons or ionsForms of Energy
Energy produced from mechanical devices
Energy that is stored in molecular bonds, the forces that hold molecules togetherForms of Energy
energy in the process of being transferred from one object to another because of the temperature difference between them.
Energy that is trapped inside each atomForms of Energy
Designed by solar engineers to be used in sun rich but fuel poor areas in the world to improve the quality of life and nutrition of some of the 2.4 billion people who lack adequate cooking fuel
Radiation, conduction and Convection
● DT – temperature gradient from inside to outside
Uw = f(Tio)
Tio = f(Uw)
r – reflectivity of reflector
M – height of reflector
a – angle of reflected light
N - # of reflectors
