yea, thats what my main topic is tonight. for the last hour or so, me and my dad have been arguing about this, and its now starting to **** me off, first, becasue to me it seems impossible. he is describing this:
Take a 12v car battery, hook a 120v inverter up to it, then take a car battery charger and plug that in to the inverter, and charge the 12v battery.
now the main reason I see as this won't work, is because it takes power to convert the power to 120v, and it also takes power to convert 120v to 12v, so you have power wasted. Plus, the inverter and charger both create heat, and heat is created by electrical resistance, which takes power. so he thinks that the system, with draw from a 60w light bulb would last about 3 years. now my point is, it will last longer with out the charger and inverter on the battery because they use power, and with out the devices connected, there will be more power left for the light.
so am I right? or is he right? srry if its hard to understand, but I kinda need the answer quick or something might get broken.
