The world is expanding every moment. With the total area of earth around 510 million square kms, of which approximately 70% is covered with water, the only scope of expansion on land is vertical. With the growing population and economies, the buildings, whether commercial or residential, are competing to touch new heights. One of the problems with such sky scrapers is their maintenance, especially cleaning or painting the walls, panes, glasses etc. on higher storeys of these high rise buildings. In most of the cases it requires a huge investment of man hours, wherein the maintenance staff members hang down from the top and clean/paint the buildings.
What do you think can be an alternative way to solve this problem? Can you suggest some other methodology to increase the efficiency of the current method or a new bot that can do such stuffs?

It is generally observed that the density of vehicles & traffic on city roads and streets is very small during late nights. However the road/street lights remain on the entire night.
How do you think can we utilize this light energy? Alternatively how do you think can we conserve this energy? |
