“…Water has a high specific heat and a very low viscosity, whereas it has a relatively low boiling point and an incredibly high vapor pressure. In contrast, oils are more suitable HTFs for most CSP systems because of their high boiling points (lower than 400 °C), relatively low costs, low freezing points, and high thermal capacities . Besides, due to the low cost and high thermal stability, nitrate salts are desirable for high-temperature applications where alternatives such as oils are highly flammable .…”

Ionic liquids (ILs) consisting entirely of ions exhibit many fascinating and tunable properties, making them promising functional materials for a large number of energy-related applications. For example, ILs have been employed as electrolytes for electrochemical energy storage and conversion, as heat transfer fluids and phase-change materials for thermal energy transfer and storage, as solvents and/or catalysts for CO2 capture, CO2 conversion, biomass treatment and biofuel extraction, and as high-energy propellants for aerospace applications. This paper provides an extensive overview on the various energy applications of ILs and offers some thinking and viewpoints on the current challenges and emerging opportunities in each area. The basic fundamentals (structures and properties) of ILs are first introduced. Then, motivations and successful applications of ILs in the energy field are concisely outlined. Later, a detailed review of recent representative works in each area is provided. For each application, the role of ILs and their associated benefits are elaborated. Research trends and insights into the selection of ILs to achieve improved performance are analyzed as well. Challenges and future opportunities are pointed out before the paper is concluded.

“…Parameters involved 3. Procedural steps R. Almanza and A. Lentz [15] stated that it is possible to generate electricity by direct steam generation (DSG) in parabolic troughs. Saturated steam at 165°C and 6.89 bar can be supplied to a 2.24 kw steam Stuart Swan motor of the two piston engine type in order to produce mechanical energy as well as electric energy through a generator, using the re-circulation process concept to produce steam.…”

Energy plays an indispensable role in modern society. India with 17% of the world population and just 0.8% of the world's known oil and natural resources is going to face serious challenges in the coming decades. Hence energy conservation has a prime importance. Besides energy independence the devasting impact of climate change has become an issue of critical consideration. Energy production using fossil fuel is the major contributor to green house gas emissions. Hence, transition towards a low carbon energy economy is the real solution for the mitigating the impact of climate change.The project at MPKV, Rahuri undertakes to highlight the constructive development of the solar energy resources and is an attempt to resource this unused energy source to drive our daily activities of the office efficiently. It was estimated that about 2332 kwh/day electricity generation is possible by using parabolic dish installation scheme at roof top of site.Index Terms -Alternate energy, energy conservation, solar energy, parabolic dish.

“…Few publications report successful experimental investigations on the use of solar energy to produce electricity at a domestic scale with Rankine cycles. In 1997, a Rankine cycle was used to recover solar energy at low temperature (165 C) and produced around 2.24 kWe of electricity (Almanza and Lentz, 1998). Later, in 2001, a radial flow turbine was used in a hybrid gas burner/solar system to produce 1.5 kWe (Oliveira et al, 2002).…”
