Lasers for Wireless Power Transmission
Abstract:
The aim of the project is to transmit power energized from lunar through laser.
In this project we the team had implemented a lunar-solar tracking system. The implementation is of 2 - section.
Section 1:
The working principle of this part is used to observe the lunar rays which generate an electrical energy. This energy is then converted into light energy by groups of laser which is capable for long distance travel. This is lighted with electronic sources. The solar cell is automated with stepper motor for tracking light density. The density is sensed by sensor (LDR) the signal is then transmitted to microcontroller and controls the stepper motor depending the light density.
Section 2:
The light energy is then converted into electrical energy by photovoltaic panels. The cell is used to observe the rays and is converted into electrical energy. The ELE energy produced is then boosted by boost converter which is then used for different power requirements.
Introduction:
Solar cells are placed in space which is capable for observing booth suns energy in day and lunar energy during night. Because sun moves in a elliptical path. So few hours the sunlight falls into the cell. During the rest of the hours the percentage of Sunlight, which falls into the cell, is very less. This results in less amount of energy generation.
To overcome this problem we can construct a model where we can place the solar cell in it and which can move according light density. To track the density, this is achieved with the help of light intensity sensors. The sensors are fixed into the model in an elliptical path. So depending on the light the sensors output differs. So according position the solar panel, this results in good efficiency. (i.e.).the solar cell can produce energy by tracking the sunlight with the help of sensors and mechanical model.
Solar power technology is not a recent advent; in fact, it dates back over 100 years to the industrial revolution. Solar energy is the mother of most renewable energies on earth. The sun powers natural cycles on earth like the wind, water flow and plant growth.
But the sun is also such a reliable source of heat and light that we sometimes take it for granted. Generations have used glass and other materials and structures to capture and magnify the sun’s energy and these systems have gradually evolved to form the basis of mature techniques that are used today to harness solar energy.
Solar panels (photovoltaic panels) convert sunlight into electricity and can be placed on the roof of a house, or nearby, to gain the greatest access to the sun. They require virtually no maintenance. It can generate electricity without any waste or pollution. Solar panels have no moving parts so they are very reliable and have a long life span. Solar panels are relatively easy to install and are very low maintenance.
These days, solar panels are becoming increasingly efficient due to improvements in design technology. The use of solar panels allows us to generate clean, renewable electricity to power remote appliances, communities, or even for high power resources.

The hardware of the thesis built by power supply, micro controller, converter board, solar panel, battery and a lamp load.
The solar panel is to generate the electric power of course the power generated by the panel is in milli voltage (mV) and milliamps (mA). There is need to boost the voltage and the current generated by the solar panel. The output of the solar panel circuit is given has an input to the converter board i.e. amplifier.
The converter board used here for the purpose of boosting. This board does two function one to sent the boosted signal to the battery and also to the ON the load.
The converter board receives the signal i.e. voltage and the current from the solar panel, it acts an input to the converter board. The converter board boosts the received signal from milli volts (mV) to volts (V) and the milli currents (mA) to Amps (A).
The converter board sent the boosted signal to ON the load and to the battery. So the load is ON by the solar energy. The use of battery is to give the backup supply to the converter board in case of the supply failure.
The battery is charged by the solar panel output via converter board. The lamp load keeps on in ON condition even in the case of the supply failure for emergency using a SOLAR PANEL…
Laser:
Low-power lasers are widely used today for telecommunication as well as for low-cost laser pointers and laser beam lights. High-power lasers are employed in surgery, and to cut, weld, and heat metal. More recently, a ground-based pulsed carbon dioxide laser has boosted research "light craft to altitudes higher than Goddard's first rocket.
Lasers are now being considered of wireless power transmission, propulsion and space exploration.
A potential application of particular interest is the use of lasers to beam power from solar collection space to other locations, in space and out he Earth's surface. The concept of space solar power systems for terrestrial power delivery was first proposed by Glaser in 1968 and studied extensively by NASA, the Department of Energy, and others in the 1970s and 1980s. It was recently revisited by NASA.
These space solar power concepts requirements is for transmitting the electric power that is converted from solar energy by the space-based power
