WIRELESS POWER TRANSMISSION

The invention of electricity and usage to light up a bulb provoked debates on ways to have it distribute it for the benefit of the people. Prominent inventor Nikola Tesla had an idea and researched how electricity can be transmitted wireless. Tesla believes that in some point in time there will be wired infrastructure that will get to complex in electricity distribution that therefore he supports for wireless transmission of electricity. Tesla made plans and built a 57 meter tower, from where electricity will be beamed to long distances. However, his research was shortened due to lack of funds to finish the projects. (Carlson, W.B 2007) Until 2007, scientists in MIT had a breakthrough in the wireless energy transmission. 

A distinctive usage of the technology will be recharging of customer electronics that uses battery without connecting to power sockets. Therefore, laptop can be used anywhere in the home and have it battery recharged without or a mobile phone automatically gets charged when user step into the house or the battery is low.

Wireless energy transfer has become a major subject in modern automation scenarios, as it offers reduced installation efforts, more flexibility with a removal of wear and tear of supply cables. Current research focuses on an inductive power supply of a single load over a possibly large distance.

This technology provides ease of mobility to users as chargeable batteries, electrical and electronics equipment can be moved around easily.  This comes with wireless Installation. It is not very costly for wiring infrastructure for devices and it will hold unlimited users who have limited slot for charging purposes of mobile installations and vehicles.

 

EFFECTS OF WIRELESS POWER TRANSMISSION TECHNOLOGY

This wireless technology of power transfer is still in developing state even though companies like Wild-Charge have started rolling out a gadget capable of charging mobile equipment wirelessly.  (http://www.wildcharge.com/). On the other hand the following needs to be addressed which might discourage the future application of the product.

1.      It is not enough for customer to achieve the ease of having less connection wires, installation etc but power consumption and efficiency need to be put into consideration. Customer power consumption cost will rise. Customers will possible not pay more to recharge mobile device wirelessly.

2.      Electronic gadget and equipment intended to be powered wirelessly have to re-design to incorporate this technology. It creates more complication in the electronic equipment while eliminating the cords and wires.

3.      Unlike wireless data transfer where security can be implemented to prevent unauthorized access, it’s doubtful in this case. For example, an outsider merely needs to get close within the outer limits of wireless power base station to make use of the electricity supply.
