Abstract

The main objective, here, is to explore the economic viability of the solar powered desalination method through a cost and benefit comparative and contrast study. Using the initial construction expenditure, the annual maintenance cost and energy consumed or produced, a variance ratio test of the random walk hypothesis will be implemented to determine their relative financial efficiency. This paper will also utilize the first order autoregressive multivariate estimation model to analyze the methods and identify the most productive process with most financial promise for future investment. The total deviations of the estimated variables from the actual are accounted for by the variations of the variances of the estimates from the actual. The higher the percentage of the unexplained deviation, the higher the risk involved. The portfolio variance will be utilized to measure the investment risk in three desalination industries.

Highlights

Water is probably the most important commodity affecting the livelihoods of the majority of the populations on the Earth
Not much literature is written on direct solar energy for the purpose of producing drinking water, not on a large scale anyway
TC/million joules (MJ) is utilized for two purposes: a) To calculate the profit under the assumption that the initial cost is financed

Summary

Introduction

TC/MJ is utilized for two purposes: a) To calculate the profit under the assumption that the initial cost is financed In this case the cost of the first year is multiplied by 2000 to obtain the present worth (PW) of the financing money for the establishment of two Giga Joules energy-plant for the production of drinking water. The actual and estimated values will be utilized to run a variance ratio test of the random walk hypothesis of both variances (Table 2), VR (qa ) and VR (qe ) , where a stands for actual and e for estimated This is employed to assess the viability of the energy producing schemes including the solar seawater desalination. The cost-effectiveness and efficiency of the desalination of seawater through direct solar energy is an asset that someday will provide the world with most of its drinking water
