Solar Chimney plus Bell Jar .... a thought experiment
Summary
The solar chimney allows direct conversion of solar
energy into electricity using natural convection. A
commercial solar chimney of height 1000 metres is proposed
but has an efficiency of only about 3%.
The author presents a 'thought experiment' to the reader. What would happen if a glass bell jar was placed over the above structure and sealed at ground level? Would there still be air flow and what would be the efficiency of conversion of solar energy into electricity?
