This is so sexi.

where do u get sodium acetate in a bag?
Oh my god, I want to do that!
P.S. Couldn't you put in a small sterling engine and turbine to make it run off the heat of the sodium acetate?
my friend, its so exciting. Please help me with one thing, how did you turn the bulb on and off.... I can connect this to the USB port but do you know how can I turn it on and off through computer?
