Jukebox’s ancestor the Phonograph (also called the gramophone) was invented in 1877 by none other than Thomas Alva Edison. This Phonograph was coin operated but was made from a wax cylinder. It was another 12 years before a man installed this in his “saloon” and called it “Nickel in a slot”. The interested fact is that that name was later shortened to “nickelodeon”. In 1906 this nickelodeon was replaced by a newer invention which had various collections of songs. By now it was called the “Automatic Entertainer”

It was in 1927 that amplifiers were added to the automated entertainer. Though it was very popular at this time but then the sales dipped rapidly during the World War II and the great depression. Once this period was over, the steepletone jukebox became something of a craze. The manufacturing companies first tried to make them in the likeness of a radio but eventually came out with innovative graphical interfaces. The jukebox has now come to the world of internet and is ruling the roost here too. One of the most highly regarded brands on the market for jukeboxes is steepletone.

Another use of solar heating is for heating interiors, homes and sanatoriums have sunrooms, solariums and greenhouses, built into the southern portions of the homes or buildings the collect the daily solar heat.

The major principle of Solar Heating and solar lighting is to build the structure in such a manner that the heat of the sun is trapped into these glass or plastic enclosed spaces which naturally  flow through the other parts keeping them warm.

The materials used are bricks or stone floors to store or hold the warm air in overnight. These are called passive Solar Heating systems, because they do not use devices or principles which involve active transfer of heat by use of oils, water or other fluids which high specific heat capacity. Solar Heating is a very viable option because the Earth receives almost 30,000 times greater solar energy annually than used in a developed country like the USA.
