Five years ago, when the relevant cost index was 120, a nuclear centrifuge cost $40,000. The centrifuge had a capacity of separating 1500 gallons of ionized solution per hour. Today, the boss wants to build a centrifuge with capacity of 4500 gallons per hour, but the cost index now is 300. Assuming a power-sizing exponent of 0.75, determine the approximate cost in today's dollars of the new, larger reactor

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 tones 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?
