charging batteries with 240V? Answered
i was thinking, wall transformers only transform so much energy(70-90%?) the rest goes off into heat.
so, wouldnt it be better to charge 160 AA batteries at the same time in serial (thus making 240V) directly off the wart?
i know this is just theory, since its not practical, not managable or anything, but i just wondered if it could be done.
would this solve the energy loss from heating the transformator up?
