SOLAR HEAT ENERGY STORAGE IN PHASE CHANGE MATERIALS
ABSTRACT
Developing efficient and inexpensive energy storage devices is as important as developing new sources of energy. Energy storage can reduce the time between energy supply and energy demand, thereby playing a vital role in energy conservation. It improves the energy systems by smoothening the output and thus increasing the reliability.
This paper deals with storage of solar thermal energy in materials undergoing phase changes. PCMs, which include salt hydrates, ....etc

Solar water heater

Solar water heating or solar hot water is water heated by the use of solar energy. Solar heating systems are generally composed of solar thermal collectors, a fluid system to move the heat from the collector to its point of usage. The system may use electricity for pumping the fluid, and have a reservoir or tank for heat storage and subsequent use. The systems may be used to heat water for a wide variety of uses, including home, business and industrial uses. Heating swimming pools, underfloor ....etc

COOLING OF HELMET WITH PHASE CHANGE MATERIAL


1. Introduction

Motorcycle helmets greatly reduce injuries and fatalities in motorcycle accidents. Thus, many countries have laws requiring standard helmets to be worn by motorcycle riders. Safety is a primary feature of a motorcycle helmet. Modern helmets are fabricated from plastics, often reinforced with Kevlar and carbon fiber. The helmet has two principal protective components: a thin, outer shell made of ac ....etc
