▁Systems ▁( AW ES ) ▁▁ ▁seems ▁more ▁common ▁in ▁the ▁research ▁community . ▁ ▁Vari ous ▁mechan isms ▁are ▁proposed ▁for ▁capt uring ▁the ▁kin etic ▁energy ▁of ▁wind s ▁such ▁as ▁k ites , ▁k y to ons , ▁aer ost ats , ▁gl iders , ▁gl iders ▁with ▁tur b ines ▁for ▁reg ener ative ▁so aring , ▁sail plan es ▁with ▁tur b ines , ▁or ▁other ▁air fo ils , ▁including ▁multiple - point ▁building - ▁or ▁terrain - enabled ▁hold ings . ▁Once ▁the ▁mechanical ▁energy ▁is ▁derived ▁from ▁the ▁wind ' s ▁kin etic ▁energy , ▁then ▁many ▁options ▁are ▁available ▁for ▁using ▁that ▁mechanical ▁energy : ▁direct ▁tra ction , ▁conversion ▁to ▁electric ity ▁al o ft ▁or ▁at ▁ground ▁station , ▁conversion ▁to ▁las er ▁or ▁mic row ave ▁for ▁power ▁be aming ▁to ▁other ▁aircraft ▁or ▁ground ▁rece ivers . ▁ ▁Energy ▁generated ▁by ▁a ▁high - alt itude ▁system ▁may ▁be ▁used ▁al o ft ▁or ▁sent ▁to ▁the ▁ground ▁surface ▁by ▁conduct ing ▁c ables , ▁mechanical ▁force ▁through ▁a ▁t ether , ▁rotation ▁of ▁end less ▁line ▁loop , ▁movement ▁of ▁changed ▁chemical s , ▁flow ▁of ▁high - press ure ▁g ases , ▁flow ▁of ▁low - press ure ▁g ases , ▁or ▁las er ▁or ▁mic row ave ▁power ▁be ams . ▁ ▁High - alt itude ▁wind ▁for ▁power ▁purposes ▁W inds ▁at ▁higher ▁alt itudes ▁become ▁stead ier , ▁more ▁persistent , ▁and ▁of ▁higher ▁velocity
