All the matter, space, and the time there ever has been or ever will be popped into existence 10 to 20 billion years ago.This tiny, supercompressed point—a “Singularity” in the jargon of physicists—was unimaginably hot and packed with energy. It burst forth in a titanic explosion and, expanding and changing ever since, it has become the universe that we—and who knows who else?—call home? If some cosmologists are right, it’s the only universe there ever has been, but there’s no way of knowing for sure.

   The heat, which may result from sources such as solar heating or burning of fossil fuels, can be converted into electricity with a very (36) efficiency through a process known as thermionic conversion. Due to the many advantages that would have a system of this type which would be tradable(37) a large scale, many efforts have been for more than half a century to try to develop a practical thermionic generator, with little luck(38)—all attempts. However, such luck may change soon, (39)to a new design: an electronic thermal(40). The thermionic generators used the difference in temperature(41) a hot metal plate and a cold to (42) electricity. Basically, it creates a difference in electrical (43) between the hot plate and the cold. The(44) voltage drives an electric current, (45) the need for movement of mechanical parts.
