Plug-In Hybrids Are a Great Idea

NULL

Hybrid-elec­tric vehi­cles can be mod­i­fied to recharge from home elec­tri­cal out­let. Com­mut­ing on bat­tery pow­er only voids the war­ran­ty. Sev­er­al OEMs are work­ing on fac­to­ry-built plug-in hybrids. Incre­men­tal costs esti­mat­ed at $10K. A lithi­um-ion bat­tery break­through is need­ed to make plug-ins afford­able enough to become wide­spread. Elec­tric pow­er plants must clean-up emis­sions fur­ther to ensure the plug-in envi­ron­men­tal ben­e­fits are actu­al and not trans­ferred to a dif­fer­ent source.

Background
Cur­rent gen­er­a­tion of hybrids reduce fuel con­sump­tion by switch­ing between gas engine, elec­tric motor
Elec­tric motor pow­ered by bat­tery recharged dur­ing brak­ing, by gas engine
Plug-ins have addi­tion­al bat­tery capac­i­ty, add recharg­ing from stan­dard elec­tri­cal out­let
