Answer:
heat and power
Explanation:
is the simultaneous production of electricity and heat both of which are used
vacuum walls: prevents heat loss by comduction and radiation
silvered walls prevent loss by radiation
ceramic base prevents loss by conduction
cap prevents by radiation and convection and reduces by comduction
