A jukebox is a machine which plays music automatically mostly when a coin is dropped into it. It has a collection and you get to choose a song from the collection. The term “juke” was taken from the African –American slang the “jook” which means dance. The steepletone jukebox had several ancestors which were invented way before 1890’s. The jukebox reached its peak of popularity after the World War II. The juke boxes were brightly decorated and many graphical gimmicks were then used to make it look very attractive.

The period from 1940’s is called the Golden age for the tem. This is not only because of the immense popularity but also because of the bright yellow plastic that was used to make it in those days. The next era came up with making the steepletone jukebox with chrome and hence was known as the Silver age. It’s still popular and is very dear to the hearts of young and old alike.

The sun’s energy has two parts of solar energy – light and heat. The heat energy is used in Solar Heating Systems which are very popular due to their cost-efficiency and easy installability, in places that receive sunshine throughout the year, like India, Spain, Greece, Africa, America, etc. There are many Solar Heating systems  – the first is called the Active Solar Heating System, it has what is known as a solar collector to heat a fluid, like oil, water, etc. Then this fluid is pumped or blown through ducts to deliver the heat wherever it is needed. The heat collected and held by the fluids than can be stored in insulated tanks made of brick or stone – a very popular heat storage system in cold countries. This system is very easy to install, generally on the rooftops or the areas that receive maximum sunlight and for longest hours.   Other options include solar lighting of which installation can be goverment funded.
