TITLE OF THE INVENTION
LASERELECTRIC GENERATOR FIELD OF INVENTION
The present invention relates to an arrangement for electric power generation by using a high power liquid laser, fibre optic light guide & unitravelling photodiodes in a system which produces high electric power in a cost effective manner. The laser electric power generator is pollution free, easy operation & user friendly. A pollution free environment can be created by this equipment. The laser electric power generator will have no smoke emission and won't produce any harmful effect eventually making it more beneficial and efficient form of alternative energy.
PRIOR ART
There have been proposal like fossil fuel engines and so called as internal combustion engine (ICE) which runs on gasoline, methanol, & petrol fuels. These engines when results in incomplete combustion of fuels releases harmful gases like Carbon Monoxide (CO), CO, Carbon Dioxide (CO 2 ), Chlorofluorocarbons (CFCs), lead, Nitrogen Oxide (NO x ), Sulfur Dioxide (SO 2 ), and other volatile compounds leading to harmful impact in the environment like respiratory diseases and global warming.
There have been proposals like the current battery electric vehicles (BEVs) using NIMH battery chemistry typically on average use 0.2-0.3 kWh/km and half of this power consumption is due to inefficiencies in charging the batteries. Cost of ownership for modern BEVs depends primarily on the cost of the batteries, the type and capacity of which determine several factors such as travel range, top speed, battery lifetime and recharging time; several trade-offs exist. BEVs most commonly charge from the power grid, which is in turn generated from a variety of domestic resources; such as coal, hydroelectricity, nuclear and others. Charging time is limited primarily by the capacity of the grid connection. Higher power level charging would probably require one hour.
The environmental impact of electricity production (indirect emissions) depends on the electricity production mix, and are usually considerably lower than the direct emissions of ICE vehicles.The propsed invention laser power electric generator could lead to power substitution to fossil fuel engines and lead to electric vehicles with high energy densities, powiV density, and long life, as all other aspects such as motors, motor controllers, and chargers cost-competitive with internal combustion engine components. The invention aims at generating electricity and providing fuels for vehicles is entirely a separate wings of the energy economy, with different energy efficiencies and environmental benefits.
OBJECT OF THE INVENTION
A large lifecycle input difference of BEVs compared to ICE vehicles is that they require electricity instead of a liquid fuel. When the electricity is provided from renewable or nuclear energy, this is a considerable advantage in terms of direct air pollution. However, if the electricity is produced from fossil fuel sources then the relative advantage of the electric vehicle is substantially reduced. So, developing additional non-CU 2 emitting energy sources is necessary for electric vehicles to further reduce net emissions. Still, the environmental impact of electricity production {indirect emissions) depends on the electricity production mix, and are usually considerably lower than the direct emissions of ICE vehicles.
The pricniple object of this invention laser power electric generator will produce high electric power in a cost effective, pollution free, and user friendly manner. The other object of this invention is to make battery electric vehicles and fossil fuel engines energy efficient and make them comply with national and international emission standards namely Bharat Stage, Euro Stage, Kyoto Protocol & others.

"A high power liquid laser system receives the power supply system from the UPS 110 watts. The H 2 O source is poured inside this laser system and it is pumped by the motor. The ptating atom is excited by the semiconductor diode pumping laser and these excited photons are collected by the laser head. The optical output of the laser 40 KW is taken out through the laser head. This light beam enters the multifurcated fibre optic guide through the coupler. The fibre optic light guide carries the laser light beam to the unitravelling photodiodes. The unitravelling photodiodes convert the laser beam into direct electric current (DC). The direct electric current (DC) is converted into alternating current (AC) through a DC/AC converter. The part of the alternating current (AC) is then taken out for the commercial purpose and remaining is fed back into the UPS power source for recharging" etc.
