This invention relates to Solar/Electromagnetic Cell( referred as Energy Cell hereafter) and Solar/Electromagnetic Energy Collector system( referred as Energy Collector system hereafter) capable of harnessing solar energy without tracking position of Sun. This also describes a basic Solar lamp and Solar Heating Element which can be used to provide lighting and heating respectively.
The Solar cell and Solar/Electromagnetic energy Collector system presented here is unique in the sense of not only being simple but it allows the concentrated energy to be transported to a location different than where its collected.
Center of this invention is Energy Cell. This is based on the principle of electromagnetic/optical reflection. Sun light or electromagnetic waves falling on vertical cone shape cells get trapped in and are guided into narrow tubes. Diameter of these tubes is much smaller than that of the mouth of the cone and hence leads to energy concentration. Output of these tubes can be further combined in a similar fashion to achieve further concentration.
Once an Energy collector system is deployed for collecting solar energy, output from these tubes can be used in various ways. Some of the examples are as below.
Energy cells can be used to collect electromagnetic radiation as well, thereby acting as antennas.
FIG. I. This shows two different types of Energy Cells
Energy Cell (
Two different types of cells can be used. The cell with lens provides greater efficiency. Each cell consists of two parts. These could be combined in one as well. Top portion is above boundary A-B. Top of these cells can be hexagonal, octagonal, or any other shape. Diameter shrinks towards the bottom and shape becomes circular at the boundary A-B forming a conical object. Bottom portion of cell starts as circular opening with diameter smaller than top of the cell and merges in to a smaller diameter tube. This tube can be a rigid or flexible based on requirements. Height of cell can be varied in ratio with diameter of top to vary the efficiency of the cell.
All internal surface of Energy Cell and tubes providing output for Solar energy will have reflective coating. Alternatively internal and external space of cell can be filled with different material to provide total internal reflection at the internal surface of the cell similar to as used in optical fiber used in communication systems. This helps guide the waves inside it.
All internal surface of Energy Cell and tubes for electromagnetic energy can be coated with suitable material which acts as reflecting surface for the wavelengths in the spectrum being captured.
Type-I: In this type cell will have vertical dividing walls in the top portion. Top can be covered with transparent surface to prevent anything falling inside.
Type-II: Here a convex cell is placed at the mouth of the cell, which helps collimate light inside the cell.
Energy Collector (
This describes the Energy collector based on type-II energy cell. Multiple cells can be placed in a plane to collect energy for a bigger surface area. These collectors can be placed on building roofs, walls, windows or any suitable surface where the radiation being captured are available. Output from these collector can be taken to destination for various use.
Infrared and ultraviolet filters can be applied at the output when its used for lighting application to avoid heating and harmful ultraviolet radiation.
Energy Collector (
This describes the Energy collector based on type-I energy cell. Except for being based on type-I Energy Cell, its same as Energy Collector described above.
Energy Combiner (
This describes the arrangement to combine output of Energy collector into less no. of tubes. This will result in more energy concentration.
Solar Heating Element (
This describes the arrangement to convert energy output from Energy collector to heat which could be used for any application requiring heating. For most part this is same as type-II Energy cell with exception that energy is an input from the tube at its bottom and at the top it has black body cover which absorbs all energy input and radiates outside the cell from top in the form of heat. The black dot on the input tube represents the intensity control/ON/OFF switch.
Solar Lamp (
This is similar to Solar Heating Element except the top cover is a made of translucent material so that it diffuses all the light coming as input.
