BATTERIES |
|
In science and technology, a battery is a device that stores chemical energy and makes it available in an electrical form. Batteries consist of electrochemical devices such as one or more galvanic cells, fuel cells or flow cells. The earliest known artifacts that may have been batteries are the Baghdad Batteries, from some time between 250 BCE and 640 CE. The modern development of batteries started with the Voltaic pile developed by the Italian physicist Alessandro Volta in 1800. The worldwide battery industry generates 48 billion dollars in sales annually (2005 estimate).

CONTEST / SWEEPSTAKES / LOTTERY / DRAWINGS |
|
A sweepstakes is technically a lottery in which the prize is financed through the tickets sold. In the United States the word has become associated with promotions where prizes are given away for free. In other words, they specifically do not require a purchase to enter (these are called prize draws in the United Kingdom). Sweepstakes sponsors are very careful to dis-associate themselves from any suggestion that players must pay to enter, as this would bring them into conflict with lottery laws. The popularity of the term sweepstakes may derive from the Irish Sweepstakes, which was very popular throughout the world from the 1930s to the 1980s.
