▁array ▁of ▁secondary ▁options ▁include ▁t ug ging ▁water ▁tur b ines , ▁p ump ing ▁of ▁water , ▁or ▁compress ing ▁air ▁or ▁hydro gen . ▁ ▁The ▁position ▁of ▁the ▁electric ▁generator ▁is ▁a ▁distingu ishing ▁feature ▁among ▁systems . ▁F lying ▁the ▁generator ▁al o ft ▁is ▁done ▁in ▁a ▁variety ▁of ▁ways . ▁Keep ing ▁the ▁generator ▁at ▁the ▁mo oring ▁region ▁is ▁another ▁large ▁design ▁option . ▁ ▁The ▁option ▁in ▁one ▁system ▁of ▁a ▁generator ▁al o ft ▁and ▁at ▁the ▁ground ▁station ▁has ▁been ▁used ▁where ▁a ▁small ▁generator ▁oper ates ▁electronic ▁devices ▁al o ft ▁while ▁the ▁ground ▁generator ▁is ▁the ▁big ▁worker ▁to ▁make ▁electric ity ▁for ▁significant ▁loads . ▁ ▁Car ousel ▁generator ▁The ▁“ Car ousel ” ▁configuration ▁several ▁k ites ▁fly ▁at ▁a ▁constant ▁height ▁and ▁higher ▁alt itudes , ▁pulling ▁in ▁rotation ▁a ▁generator ▁that ▁moves ▁on ▁a ▁wide ▁circular ▁rail . ▁For ▁a ▁large ▁Car ousel ▁system , ▁the ▁power ▁obtained ▁can ▁be ▁calculated ▁as ▁of ▁the ▁order ▁of ▁G W , ▁expos ing ▁a ▁law ▁that ▁see ▁the ▁power ▁att ain able ▁as ▁a ▁function ▁of ▁the ▁diameter ▁raised ▁to ▁the ▁fifth ▁power , ▁while ▁the ▁increment ▁of ▁cost ▁of ▁the ▁generator ▁is ▁linear . ▁ ▁Aer ost at - based ▁H A WP ▁One ▁method ▁of ▁keeping ▁working ▁H A WP ▁systems ▁al o ft ▁is ▁to ▁use ▁bu oy ant ▁aer ost ats ▁whether ▁or ▁not ▁the ▁electric ▁generator ▁is ▁lifted ▁or ▁left ▁on ▁the ▁ground
