invertor question

heres one for you all.

those invertors that take your cars 12v supply, and make it into a 240v socket, to power stuff with.

if you plugged the invertor in, then attach a 12v battery charger to it, and then connect the charger leads to the battery, will it charge the car battery??

hmm

no, it will discharge the battery.

Ideally with an Inverter you should use a dual battery system so you dont drain down the battery for the car, this requires some wiring for a split charging system. Well documented in Caravan Club books and the such I think.

why would you want to do that?

Probably wouldn't but just curious like me. For example. Would a car with a wind turbine on it run forever once it got going because car runing turn the fan, fan powers that car, and so on, ever lasting power?

Same with a Solar powered light infront of its own solar pannel. Once it's lit will it burn forever?

no, and no, both for very obvious reasons.

just curious!!

its just a question to stimulate thinking, I think it would work, but I dont have an invertor to find out..

Levemir and Jon, what you're proposing is the same as "perpetual motion". As none of the devices are 100% efficient then none of the proposed options are possible.

Perpetual motion only ever happens in the worlds of Heath Robinson, Roland Emmett and Punch.

theyre very ineficiant. where would the extra electric come from? lol
