It is quite obvious and known to all, irrespective of whether you are a science major or not, you all will be knowing that temperature keeps rising on our planet and also that heat rises upwards. But have we ever imagine that it can come out to be a free fuel alternative for future. I am sure you would be thinking of its feasibility by now but good news is its not only feasible but an Australian company EnviroMission is already working on the same.
We have already seen electronic devices which cools the surrounding because of the heat transfer from hotter bodied to colder bodies like in refrigerator. Depending on the similar concept, the main idea of the entrepreneur Roger Davey from EnviroMission is to design one such solar chimney which will allow the rising air to go out of the building, taking the heat with it. This rising air will turn 32 turbines mounted on the tower and they will be turned to spin fast enough to generate electricity. The goal is to create, capture and control hot air to help power cities. EnviroMission has its plan to build a huge solar updraft tower, 2600 feet tall, in the Arizona desert.
A plus-point for this energy over the other renewable sources of energy is that solar and wind both are subjected to limitation as solar energy is not effective at night and wind energy is suitable only for coastal areas. But the heat air movement is a very common phenomenon is any region at any particular time so the energy generation will be more spasmodic and hence more reliable.
Surely there is lot to be done yet and a number of huddles to overcome but not doubt the concept is brilliant and of course the need for the time as energy sources are depleting day by day.
