Excellent Wireless Electricity essay writing service: professional academic help
In the world of today, with increasing modernity, there is continuous demand for more mobility as well as accessibility. The trend has boosted the demand for wireless power dramatically. The future is, therefore, seen in technology as it gives hope of the alimentation of the use of cords and batteries and promises benefits to the environment, economy, society, as well as a boost to science and technology. However, the research on the technology is ongoing and demonstration phase is still at its infancy. This write up discusses wireless power technology as an efficient technology that confers benefits to both the consumers and the environment. The paper examines how wireless technology works and discusses ethical, environmental and biological impacts of the technology in our society.
According to Firestone (2009), wireless energy transfer can be defined as a process in which electrical energy is transmitted without interconnecting wires to an electrical load from a power source. Connecting wires are not very efficient in power transmission due to resistance which causes up to 26% power loss. Scientists have therefore resorted to wireless power transmission which, besides its efficiency, gives clean power sources and reduce untidiness due to dusty power cords. The use of wireless electricity, therefore, presents a noble alternative for the transmission of electricity.
History of Wireless Technology
Murdoch and Thompson (2008) note that the idea of wireless power transmission is not new phenomenon though it may sound futuristic. The theories of this technology were proposed in the late 1800s and early 1900s by Nicola Tesla. Though his work was quite impressive, it did not result to immediate widespread of practical methods. However, this technology is drastically becoming popular in the 21st century.
How Wireless Electricity Works
Wireless power technology employs resonant energy transfer and uses coil and capacitor of high frequency resonance (Tracy, 2012). To recharge an electric toothbrush, three steps are followed. In the initial stage, an electric wire is used to direct current from the wall outlet into charger, then into the base coil. As the current moves through the base coil, a magnetic field is generated. Consequently, current is induced to flow in the coil in the toothbrush handle. This process charges the toothbrush battery. The products have coils which are inbuilt and are able to induce the flow of current in the coils of devices within the proximity. However, such devices must have compatible coils as well as circuitry, which are necessary for power transfer (Roundy et al, 2004).
Political and Legal Influences
The technology has widely been welcomed in many countries around the world. This has been due to the common understanding that that it presents an alternative to seemingly environmentally dangerous sources of power. Wireless electricity has, thus, impacted positively a good number of countries, especially those, which embraced it early enough. Since its innovation, various political leaders and environmental scientists have campaigned for the technology in their countries as well as during various world forums (Firestone, 2009).
Ethical, Health and Environmental Effects
Humanity is, to an extent, influenced by ethical implications, resulting from use of wireless power. The implementation of the new technology has created tension as it raises various environmental and human health concerns. Roundy et al (2004) noted that, irrespective of excitement, which accompanied the innovation of the technology due to its enormous benefits, its downfall and drawbacks cannot be downplayed.
However, the technology has great potential benefits to the environment. For example, the technology offers replacement for batteries, which usually contribute to landfills, causing degradation and poisoning of the environments due to the leaching of acid in the soil. Additionally, the technology has helped conserve energy by replacing the initially prevailing technologies, whose fuel consumptions were higher. Ethically, Mohammed et al. (2010) note that, its reduced effects on the users coupled with the fact that it is environmentally friendly has led to its widespread use all over the world.
According to Mohammed et al (2010), even though many people are attracted by the notion that the technology is cheaper, this is only true after its installation. They note that the initial cost of installing the technology is quite high. It also affects communication systems since it interferes with microwaves.
In conclusion, wireless technology has the potential of improving the economy due to its high effectiveness and efficiency. However, more research needs to be done to enable the infant technology overcome the various challenges which tend to limit its acceptability and use.
