What an international news agency reported from Tokyo could well be the news of the century. The electrifying news item was about transmission of electric power without wires, using 'microwave' technology. This is an epic breakthrough in the gamut of electrical power transmission that was made possible by successful experiments carried out by Japanese research scientists. They could deliver 1.8 kilowatt of electric power, with impeccable accuracy to the receiving unit kept 55 metres away. This was announced by the Japan Aerospace Exploration Agency (JAXA).
The programme was taken up way back in 2009 and now six years down the road, the breakthrough has been achieved. This is very important as Japan has a huge demand for electric power and with no local fuel resource, it has to import all fuels needed for power generation. Also their atomic power plant is exposed to local storms, cyclones as the recent disaster demonstrated it and is no longer a safe option.
Japan, being an island, can import power by wireless from China, Siberia or Korea which are quite close. With more advancement of this unique way of power transmission, it can even get power from Australia, which is in a position to generate and export power given its vast resources of thermal power as well as voltaic panel-based power plants across the Australian desert that is now lying wild and uninhibited. This success can herald a breakthrough for Japan's access to more electricity.
