Decorate the building exterior with Solar cells
The Global warming is gearning up day-by-day, the summer days are not just hot, but they indeed very hot, sweaty and one would like to just to miss it.
With the huge population and limited power generation resource, its bound that there will be regular power disruption is most of the cities in India.
In order to make life better in the current situation, was thinking of covering the building exterior with solar cells, for generating power. This would help us in multiple ways.
- Building can generate power from renewable source and hence dependency on non-renewable source is reduced.
- Since most of the heat energy will be absorbed by the solar cells, the building interior should be relatively insulated from the outside heat and will be require less amount air-conditioning.
- Global warning is bound to increase the temparature and so will be the power generation from solar cells.
- No need to paint the building exteriors, as they will be coved with solar cells. Most of the paints contain harmful chemical, with directly or indirectly affects all life and these will be avoided.

- …
Well there is no end to this list. Let start exploring, implementing and living in greener ways.

Better Traffic Control in Ruby Golpark More, Kolkata, India
Traffic in Ruby More (see crossing in Wikimapia) is always chaotic esp as the Unionised vehicle drivers (Auto Wallah etc.) do not follow signals. Given the political realities need to find a solution that will enable Auto to by-pass the More, drop passengers and return back.
