The present electricity generation system is not very efficient in terms of energy transfer, referred to as ‘line losses’. About 20 to 30% energy is lost during the distribution of the electricity. Therefore the scientists are working on projects to improve the ultimate electricity supply. Scientists are looking for alternate and efficient technologies to provide 100% electricity transfer. The change and development in the various fields have brought more client satisfaction and output. Therefore the wireless transmission of electricity is also on move.
The Technological Development:
Nikola Tesla is known as the father of wireless transmission. The most famous wireless technology known as Wardenclyffe tower also known as the Tesla tower, is the first designed merely for wireless transmission of electricity. Wireless transmission of electricity is aimed at providing electricity connection to people living in remote areas. The recent transmission technologies are based on the microwave power transmission. This task is often completed by using solar power satellite, placed in high earth orbit. This satellite converts the sunlight into energy; this energy is composed of microwaves. These microwave signals are transmitted to an antenna on ground which is further converted into electrical power.
So far there are two shadow sides of electricity, one is tangle of cable or wires and the other one is use of fossil fuels for electricity generation. Fossil fuel electric plants generate greenhouse gases which are responsible for global warming. Wireless electricity transmission can overcome these problems well.
Merits of Wireless Electricity Transmission:
First of all the wireless electrical transmission of data removes the need for physical infrastructure like grids and towers. In this way the cost associated with deploying towers and cables can be saved. During the rains and after natural disasters it is often hard to manage the cables and towers. It is possible to deliver electricity connection to the under developed areas of the world where there is no infrastructure support.
The transmission and distribution loss associated with traditional electricity grids can be overcome. African countries are in severe need of electricity connection in order to dig through the water reservoirs beneath the crust of Sahara desert. The market potential for the wireless transmission of electricity is very high. It is an opportunity market for many. Today, two words are ruling the world “efficiency” and “speed”. These two words have become the base for the development in the technology. The electricity generation using microwaves is more environments friendly. Moreover, it does not involve any emission of carbon gases. This technology can meet the electricity demand of the third world countries with economy and accuracy. Thus the ultimate benefit of this technology is transmission veracity and integrity. Many countries can enjoy the economic benefits of this technology. A signal resonant energy receiver is an ultimate device to connect various electrical applications. The monthly electricity bills using conventional electricity supply can be cut to very low.
Demerits of Wireless Transmission:
Biological effects associated with the wireless transmission of electricity due to the high frequency microwave signals is the first demerit of this technology. This project is a one time expense but it involves a lot of initial expenditure. It is expected that the price of receiving electricity through this technology would decline overtime. This technology is limited to the use of few technologies like solar satellites and Tesla grid. The transmission of electric current through this mode is susceptible to security risks like cyber war fare.
The United States Department of Homeland Security is helping to remove the vulnerabilities associated with smart grids. This department blamed chain and Russia for infiltering the system by sending software effects which would distract the entire system. Hence the power insurgency is difficult to handle in case of wireless transmission of electricity.
