Always something [img]smile.gif[/img]


I have to comment on what you said Lioness.
Your total amount of energy ´wouldn't keep a bulb lit for that long time.
First, all the energy just don't keep a lightbulb lit. It is powered by electricity, but the electrons in you takes up a very small part of your mass. Less than 0.001 u I am sure.

And ofcourse, to be picky, the bulb would burn out after some time [img]smile.gif[/img]



I don't think she meant it was physically possible. She rather used the light bulbs rate of energy consumption to represent how much potential energy was in her mass, if a perfectly efficient way existed to convert her potential energy into a form usable by a perfectly efficient light bulb with perfect components that did not wear with use. In other words a perfectly impossible situation, but a neat way to practice with the formula.
