Power vacuum [Engineering Batteries]

This paper discusses about the viability of electric vehicle. The electric batteries are so heavy, and take so long to charge, so the usage of electric vehicle is not convenient. As no one is expecting a sudden breakthrough in battery technology, rental schemes such as these may be the only way to improve the chances of success for electric vehicles in the near term. And in electronics more widely, it is all about designing around the limitations of batteries rather than hoping new forms will arrive that rewrite the rules on how much electrical energy you can get into the same space.
