The construction of PV solar cells uses a number of critical elements. One is indium, an ingredient of the transparent conducting coating on the surface of the cell. The average material intensity for indium in solar cells is approximately 0.05 kg/kWnom. Calculate the quantity of indium that would be required for a project that would provide PV solar power with capacity factor of 0.25, sufficient to meet one third of the present needs of the US, population 301 million, each using an average of 10.2 kW. The current world production of Indium is 600 tonnes per year. If the solar project were to be implemented over a 5 year time span, is it true that the supply of indium be adequate? True False

The method of ventilation is commonly used for environmental control of airborne toxic material. There are TWO (2) types of ventilation techniques; local and dilution ventilation. The most common example of local ventilation is the standard utilitylaboratory hood and standard bypass laboratory hood. QUESTION: In a separate table, discuss the advantages and disadvantages of both types of the hood.
