Gandhian way of home cooling

“All exploitation is based on co-operation, willing or forced, of the exploited. However much we may detest admitting it, the fact remains that there would be no exploitation if people refuse to obey the exploiter.” – Mahatma Gandhi

I think annoying sunlight in Indian summer is somewhat similar to exploitation. We suffer from it because we accept to suffer from it.

We first let the sunlight hit our buildings and heat them up. Then we run air-conditioners, which in turn burn electricity, which in turn burns coal, which in turn makes summer worse.

This vicious cycle can be broken easily by rejecting sunlight.

I conducted an experiment in 2008.

I took two brick enclosures of cube shape of 3 feet sides each. One of them was covered with normal roof tiles. The other one was covered with roof tiles overlaid with waste CD’s, reflecting most sunlight back to the sky.

When the temperature rose to 36 C in the non-reflecting cube, the cube beside was just at 32 C!

CD’s are no great reflectors of light. Had I kept aluminum sheets, my results could have been even better.

That is it! I refused the excess of the nature and I had a comfortable day!

It is a great business idea for the one billion population country where temperatures raise t0 >50 C and most people don’t even have electrical power in summer days.
