Dear research community, i am wondering if it would be great to create an AC battery; i.e., the battery that produces alternating current directly? Perhaps all present-day electrical devices require AC voltage for input; hence the need, e.g., to convert DC produced by solar cells to AC. Also, AC can be transmitted over big distances with lesser losses than DC (thanks to N Tesla!). Reagrdless of whether it is possible or not to create a practical AC battery, please share your opinions on the matter.
