A NEW SOURCE OF ENERGY-CHIMNEY

here we got success in finding a new source of energy.A chimney can generate electricity.we can built a chimney in desert with diameter in terms of hundred meter at foot and at head in terms of inches.The chinmney will paint by black colour so in the desert it will get hot due to sun rays. So air in the chimney will get hot and will go to the head but as the diameter of head is very narrow the speed of air trying to go up will increase and it will roll the turbine connected in the neck of chimney the one way inlate valve at the foot will allow the cold air to get into the chimney.This system is very usefull in desert wher tempreture is very high and it does not requre regular maintnance....
