Sustainability

The biggest curse of modernisation is probably the environmental damage out of green house gases and carbon emissions. Consider the falling air quality index levels in metropolis and the pollutants and toxins released by municipalities in rivers and seas. Global temperatures are rising, weather parameters are taking a bad shape and what the earth would undergo in a hundred years is a wild imagination guessed by scientists and meteorologists. We have all become well conversed in all this over the past few years.
So what have we done to correct this situation? Modern management stresses not to have corrections or mitigations but to have a solution and system devoid of it.
A small news item in a newspaper has triggered my mind. It says a device made out of a paper, pencil and a Teflon tape can generate enough electricity to operate a remote control that requires a 3 Volt charge. I chanced to encounter recently with a kitchen basket that converts household trash into compost and requires nothing to be disposed away (Imagine how you could get away with the entire garbage disposal system of a city). I recently saw a video of an artificial tree depicting wind energy which had about one feet long rotating cylindrical wind-mills jutting out vertically from its several branches producing electricity (what an amazing sight?). A successful entrepreneur, taken to a social cause, has manufactured a bicycle when run for an hour manually, can produce enough electricity to light 24 filament bulbs and a fan for a day.
Magical inventions, are they not?
We long back devised water falling on turbines through penstocks so as to generate electricity. We have used invertors to store electricity so as to be used when there is a shutdown or for starting cars. Likewise there are eco-inverter air conditioners that are power saving. There are LED lights replacing CFL’S that are more energy efficient.
We are at the cusp of a revolution. Humanity will survive as long as the wind keeps blowing, the sun spreads light, the rivers keep flowing and the seas keep churning. There is enough hope. Back to nature!
