Early morning is one such paradise which always makes you feel good. If something is giving you some refreshment, then it will add zest to that paradise. Coffee is one such item which surely makes you feel like you're in heaven. Filter coffee was the first method used for the preparation of coffee in which coffee beans were crushed and put into filter. Hot water was poured into the filter and the beverage obtained from it was used to produce coffee.
Later, coffee powder was grained and obtained in coffee particles which are small particles of coffee like sugar and they were mixed with milk. Thus, the generation advancement helped to update the production process in a different manner. Later, readymade coffee machines were introduced and coffee was prepared at ease. These machines automatically produce essence of coffee with the help of some filters and you can even get your desired amount of coffee from them. Normally you can prepare 12 cups of coffee in a single process.
Now, the latest advancement in coffee making is the solar powered coffee machine. This machine basically works on the principle that sunlight is the ultimate source of energy and it is used to heat water. The boiling process is used to produce the desired cup of coffee. This coffee maker is not only helpful in preparing coffee but also helps in preparing tea either.
This machine is provided with solar panels which are powered by sunlight. These solar panels are provided with built-in lithium battery. The water can be stored in this panel and it is effectively heated with the help of solar energy available. Normally, it is estimated and calibrated that 0.03-0.04 kw/h energy is required for boiling of water and it is obtained from solar energy.
A 10cmX10 cm solar panel can effectively generate 0 .1 Kw/h energy. Thus, if sunlight is imbibed by this solar panel for eight hours a day, it will result in the production of approximately 22 cups of coffee per day. The striking feature is that the energy available is solely obtained from sunlight and it's totally inexpensive and eco-friendly.
Since this is portable, it can be moved indoor and outdoor with much ease and it is free from electrical connection. One type of solar coffee maker employs a mechanism in which your desired coffee maker is about to use a rod to heat the water with the help of solar energy. When the temperature in it reaches nearly 80 degrees, a built-in thermostat will automatically switch off the process. During the thermostat initiation, a light will turn on to indicate that the solar coffee maker is working. After some moment of time, the light will turn off which will indicate that that coffee is ready and you can enjoy the aroma of coffee. The rod is pushed up with the help of green top present at the top. This mechanism is very similar to a ball point pen.
The most important aspect of this coffee maker is its eco-friendly nature. It won't pollute atmosphere since the energy is obtained from sun. But one of the issues associated with it is the model like this have not hit the floor of commercial market yet. All the concepts are still theoretical and conceptual. Certain things are really uncertain regarding the amount of coffee produced and energy required to heat the water. Still, some controversies regarding the fulfilment of the customers are also raised. In order to experience the aroma of coffee with solar power, you have to wait for some more time.
