As the 3rd world is fighting hard on global
climate deal, shirking away the responsibilities for the green house gas emission,
an innovation under process from an Indian Scientist can eliminate the risk
posed for the earth atmosphere.
Sarbajit Banerjee, an associate professor at the
University
of Buffalo, a state university of New York and his research team
recently pioneered an innovative window coating that blocks heat when hot and
allows it to enter when cold. This has become a breakthrough innovation in the
fight against global
warming
"Through research, we discovered that high
temperatures caused the compound's crystalline structure to change from one
that is transparent to heat to one that actually reflects it. When formed as
thin nano wires, the vanadium oxide could be directly applied as a coating on
glass. That's how this smart window - capable of reflecting heat at high
temperatures instead of allowing it to pass through the glass - got invented.
Conversely, in colder temperatures, the coating remains transparent and allows
both light and heat through to warm a building's interior," adds Banerjee,
who was named as one of the world's top innovators under the age of 35 by MIT
Technology Review in 2012
According to him, around the world, billions of dollars
are spent every summer on air conditioning to cool homes, factories and
vehicles, while releasing hundreds of millions of tons of harmful carbon
dioxide into the Earth's atmosphere.
A 2012 report published by Transparency Market Research
valued the global air conditioning market at $98.2 billion, with projected
growth reaching $178.4 billion by 2018. With this heat-blocking window coating,
our goal is to transform windows to adapt dynamically to the
external-environment instead of being static, immutable structures that are
gluttonous in their energy consumption," shares Banerjee, who is currently
in the process of licensing his heat-blocking window coating to industrial
partners in the United States.
Banerjee also has a partnership with Tata Steel in Mumbai to explore how to use the coating to
deflect heat from the corrugated steel roofs in India and other parts of the
developing world. He predicts that it will cost just 50 cents per square foot
once this window coating is commercially available.
This is going to be an impact innovation as it has
multiple positives. One, it helps to mitigate global warming risk which can
translate into better quality of life for the future generations and the other
is, it also can help people to live in conditioned temperature without air
conditioning equipments.
The negative will be for the global air conditioning market
which can shrink sharply if this becomes effective, in terms of its purpose and
price.
Here comes the criticality of “Reverse Innovation”. The
development of such products should happen at third world countries which can
help to keep the cost low thus making the innovation more affordable when the
product comes to the market.
