Nanotechnology based Mega Machine Design for Large Scale Air Cleaning – Prospects and Challenges

Air pollution is a major component of environmental degradation in the 21st century worldwide due to the increased use of fossil fuels in various industries and their contribution to contaminating the natural atmosphere around us. Environmental pollution is posing a challenge to human existence and the continuation of human generation on this planet. Environmental degradation is considered a major affecting factor of climate change which includes both global warming driven by industrial emissions of green gases and large-scale shift in weather patterns. This problem is growing on a large scale throughout the world and poses challenges to survival and sustainability. Nanotechnology being universal technology can be used to solve this problem of environmental degradation by cleaning the degraded air on large scale and can counter the contribution of natural and industrial pollution. In this paper, the proposal of construction and use of nanotechnology based mega machine is analyzed and the prospectus and challenges of such machine production and maintenance for large scale air cleaning are discussed. The advantages, benefits, constraints, and disadvantages of production and use of such mega machines from various stakeholders’ points of view are identified. Finally, the idea of self-sustainable nanotechnology filters based mega machines is proposed using solar/wind energy supported systems for automatic and self-sustainable use
