Title: Energy transport system and transport method thereof

Description:
TECHNICAL FIELD 
     The invention provides systems and methods for charging one or more electric vehicles. More specifically, the invention provides for systems and methods for electrically charging one or more electric vehicles. 
     BACKGROUND 
     Over the last decade, there have been major efforts to develop battery-driven electric vehicles for land, sea and air travel. These vehicles are aimed to reduce the pollution from current vehicles, as well as reducing dependence on fossil fuels. Among other things, one problem of current electric vehicles is that their batteries provide limited power for short trips compared to vehicles with combustion engines. Moreover, current battery charging techniques are slow and time-consuming, increasing both the journey time and the dependency on charging stations. Another problem is that the power may be used up in traffic jams, air-conditioning and heating of the vehicle and the actual distance travelable by the vehicle without charging may be significantly less than the original estimate typically less than 200 kilometers for single charge. These disadvantages render electric vehicles impractical and uneconomic. Most of all, building an infrastructure for charging stations presents economical obstacles.
