Radio wave reflector focusing electron wave of solar radiation and thermal storage unit using electron wave

Abstract

The present invention relates to a thermal storage unit using an electromagnetic wave of solar radiation, more specifically, to a thermal storage unit that converts and stores energy of an electromagnetic wave of the solar radiation which is irradiated on to the earth's surface of a large area in the form of a thermal energy in an electromagnetic wave state and uses the stored thermal energy whenneeded. The present invention comprises a radio wave reflector focusing an electromagnetic wave of solar radiation, a waveguide leading and guiding the collected electromagnetic wave energy, an energy conversion and storage unit converting and storing the electromagnetic wave energy that is transmitted along the waveguide in another form of thermal energy, and an energy supply unit utilizing the stored thermal energy in the energy conversion and storage unit for general use. Even though the radio wave reflector and the energy conversion and storage unit are installed at a distance considerably far from each other, the thermal storage unit of such configuration can improve solar radiation use efficiency to a maximum, by guiding, through the waveguide, the solar radiation having been focused to the radio wave reflector to the energy conversion and storage unit in an electromagnetic wave state.

Description

technical field [0001] The present invention relates to thermal storage units using electromagnetic waves of solar radiation, and more particularly to thermal storage units that convert and store the energy of electromagnetic waves of solar radiation irradiating large areas of the earth's surface in the form of thermal energy, and use the stored energy when needed thermal energy. Background technique [0002] Generally speaking, conventional technology mainly uses solar heat or sunlight to collect solar heat for houses by means of solar collectors. The collected thermal energy is provided to the thermal device through a phase change material (PCM) such as water. Recent technological advances have made it possible to directly generate electricity through semiconductors used in solar photovoltaic power generation systems. The generated electricity is used by individual households, and sometimes the surplus is sold to commercial power companies. [0003] However, due to diff...

Problems solved by technology

[0003] However, due to difficulties in transporting the collected heat, most conventional technologies using the sun's heat are really only used for small-scale electricity generation purposes, such as heating homes or street lighting

In other words, the disadvantages of current technology are that the heat loss is high and the installation cost of heat transfer equipment is so high that the cost efficiency is very low relative to the use efficiency of the sun's heat

[0004] In addition, most modern semiconductor devices for solar photovoltaic power generation still maintain a light (solar) power conversion rate of about 10%, which is inefficient.

Even with possible improvements in conversion efficiency, there are limits to the practical use of the radiant energy contained in sunlight, and this thus hinders the efficient use of solar thermal energy that strikes the entire Earth's surface
