ABSTRACT
The objective of this project is inserting the coin using charge for your mobile phone in public places. This project is very useful to people who are all using mobile phone without charging condition in pubic places. In this project, who are all using mobile phones in outside of home are office without charging condition. The coin based mobile phone charger is very useful to that person for using coin to charge for that mobile. The IR (infrared) transmitter is used to transmit IR signal in the transmitter side. The IR receiver is used to receive the IR signal in the receiver side. Between the IR transmitter and receiver, insert a coin to change the polarity of pulse in SCU input. The SCU is used to converting low pulse to high pulse and that pulse is inverted in inverter. The 555 IC is act as a timer to produces high pulse for particular time period. Again the SCU is used to converting low pulse to high pulse and this output is give to input of driver circuit. Driver circuit is used for provide the sufficient input voltage of relay. The relay will on to activate the 230v charger, we will use charger to charge for our mobile phone.

WORKING PRINCIPLE
CHAPTER 02
2.0 WORKING PRINCIPLE
In our vibration alarm system, we will be having
• Infra Red sensor,
• Amplifiers,
• Comparator and
• Relay
The Infra Red sensor is used in this circuit. If there is any interrupt between the IR LEDs, the sensor senses and sends the corresponding electrical output signal to amplifier circuit.
The amplifier circuit results in further amplification of signals. The amplified signal is given to comparator. The comparator compares the incoming signal with reference. If the incoming signal is more, it operates the relay.

BEAMED POWER TRANSMISSION FROM SOLAR POWER SATELLITES
1. INTRODUCTION
The desire of the modern man for more and more amenities and sophistication led to the unscrupulous exploitation of natural treasure. Though nature has provided abundant source of resources. It is not unlimited. Hence the exhaustion of the natural resources is eminent. The only exception to this is sunlight.
Scientist who had understood the naked truth had thought of exploiting the solar energy and started experimenting in this direction even from 1970. But the progress was very slow. Much headway is yet to be made in this direction. However as the impotents source of non-conventional energy and due to the limited source of conventional energy emphasis has given for the better utilization of solar energy.
But the application of solar cell, photovoltaic cell etc, we are able to concert only a small percentage of solar energy into electrical energy. But by using beamed power transmission from solar power satellite we can envisage a higher percentage of conversion. By beamed power transmission, we can extend the present system of two dimensional transmission network to three dimensional, if does not have any environmental problem as well.
2. SOLAR POWER SATELLITE
The solar power satellite concept would place solar power plants in an above the earth where they could convert sunlight to electricity and beam the ground based receiving station. The satellite would be placed in sow called geostationary or earth synchronous orbit. 24 hour orbit that is thus synchronous with earth rotation. so the satellite placed their will stay stationary overhead from earths receiving antenna
The solar power satellite will consist of a large number of solar cells mounted on a frame of steel reinforced lunarcrete. the solar cell produces electricity from sun with no moving part. the only moving part of the satellite is the transmitter antenna, which slowly tracks the ground based rectenna while solar array keeps facing the sun. each transmitter antenna is connected to solar array by two sotary joints with slip rings.
Because solar panels generate low voltage dc, super conducting transmission line is used for transmission to microwave beamer instead of conventional copper conductors. operating super conducting transmission line at low voltage reduces the chance of voltage breakdown.
The vision is to generate a large Solar Power Satellite (SPS) system for space applications. In contrast to classical designs of solar power stations, the solar energy collected by the SPS system will not be beamed to the Earth's surface, but used to provide for the required electrical and/or propulsive power for vehicles in Earth orbit (LEO, MEO and GEO) and/or deep space vehicles. Transmission of the energy to these space vehicles is foreseen thought either beamed microwave or laser power at a power level that can substantially rise above todays power levels up to e.g. 20-50 kW per space vehicle (e.g. for a
telecommunications satellite in GEO). This power is received by a relatively low mass microwave or laser collection and rectifying system on board of the satellite.
The use of beamed energy from a solar power satellite offers space vehicles the advantage of omitting (part of) the heavy on-board power generation system and or maximizing propulsive performance (in terms of propellant consumption), thereby allowing for a reduced launch mass or an increased payload mass. It also allows us more flexibility in the power take-in thus providing us with a capability for e.g. short high power applications without the need of relying on costly batteries or to reduce power without the need to dissipate excess power. Other potential advantages for the receiving vehicle are
• Omitting the solar wings frees up two faces of the satellite for e.g. the installation of antenna's and/or other equipment;
• Reduction of thermal problems;
• Less complex structure.
The physical separation of the power generation onto a separate platform allows for an independent optimization of the power generation, without the need to consider the spacecraft. For example, this could open up an opportunity to operate the power satellite at very low temperatures ensuring high solar cell efficiency or to use other (more efficient) ways of harnessing solar power, like dynamic heat engines (o.a. Stirling engines).
• Market demands: Size, power, number of users (satellites), power need per satellite, etc.;
• Economic viability/business plan: System life, life cycle, date in operation, laucher selection, development cost, etc.;
• Efficient power conversion both at SPS and receiving satellite (e.g. dynamic or static conversion);
• High power transmission by laser and/or microwave: Size/mass of receiver and/or transmitter, cooling requirements, etc.;
• Light weight structures (flexible or rigid);
• Pointing (accuracy & stability);
• Orbit (LEO, GEO or other);
• Impact onto space plasma environment;
• Impact of space debris;
• Safety (ISS, other spacecraft, launchers, etc).
