this means that the cables on the positive side are empty until a connection is made to negative - ermm nope. both negative and positive are live depending on if there is a device in between for instance, a switch and lamp. if you insert a switch and lamp to "length" of wire then connect the switch end to the positive battery terminal and connect the lamp to the negative battery terminal. the cable running from the positive battery terminal with the switch in the off position is "positive live" with voltage running in it. the cable from the other side of the switch that is connected to the lamp and out the other side to the negative battery terminal is "negative 0v". when you flick the switch too on then everything becomes "live" and lights the lamp.
this is a good thing as empty cables run cooler than full ones. yup 0V cables do run cooler as there is no "power" going through them.
The connection of negative to frame acts as a heatsink. nope.... as the cable running the "power" is a separate entity so unless you can run the cable on top of or inside the metal then it will not have a heatsink value. what you can do is use the frame as a "giant wire" and a COM to connect the otherwise bundle of "negative" wires. the frame does not act like a heatsink pulling heat away from wires.
i think i have said enough on the matter so if you want to keep arguing then get your facts right

Your reply indicates that you took what I posted seriously
Irony and sarcasm do not come over well on forum posts.
@seeker, according to Newtonian laws centrifugal force need to exist to balance centripital force otherwise the centripital force would push the object towards centre of rotation until it reached the centre, and why do liquids and gasses behave differently to solids when spun around a fixed point, where the heavier parts ( example, the cells in blood and the uranium atoms in gas) move to the furthest point from axis, and are not pushed inwards by centripital force. And how does a spin drier work ?
