Dealing With the
Future
![Page 2: Dealing with the Future](https://reader034.vdocuments.net/reader034/viewer/2022042610/568c52c11a28ab4916b7f52c/html5/thumbnails/2.jpg)
More Q’s than A’s!
![Page 3: Dealing with the Future](https://reader034.vdocuments.net/reader034/viewer/2022042610/568c52c11a28ab4916b7f52c/html5/thumbnails/3.jpg)
The Myths . . .
Costs more to cut carbon
emission
Will Carbon reduction make life
easier?
![Page 4: Dealing with the Future](https://reader034.vdocuments.net/reader034/viewer/2022042610/568c52c11a28ab4916b7f52c/html5/thumbnails/4.jpg)
More Myths . . .
• It costs more to build green
• Costs more to live green
• We can’t go grid-free on energy,
water and waste in cities
• In today’s world we can’t go prosumer
• Localising energy generation is way
too expensive!
![Page 5: Dealing with the Future](https://reader034.vdocuments.net/reader034/viewer/2022042610/568c52c11a28ab4916b7f52c/html5/thumbnails/5.jpg)
Even more myths! • Water cannot be managed at your home
• Central supply of water/energy is the only
solution … and local solutions are not
reliable / need incentive
• It’s not for us to worry about risks of abuse
of resources as consumers, citizens or
corporate citizens. It’s up to the ‘Govt’
![Page 6: Dealing with the Future](https://reader034.vdocuments.net/reader034/viewer/2022042610/568c52c11a28ab4916b7f52c/html5/thumbnails/6.jpg)
• Business of business is to maximize gains.
Up to government to deter or encourage
‘responsible’ things.
• Why should we do any thing, anyway?!
• The world’s alright. Damage we are doing
is too small --- it cannot make a difference
to the planet
![Page 7: Dealing with the Future](https://reader034.vdocuments.net/reader034/viewer/2022042610/568c52c11a28ab4916b7f52c/html5/thumbnails/7.jpg)
• Global warming and Climate change
is part of Earth’s cycle of 10K years.
The next Ice age is ‘close by’, and so
the changes.
![Page 8: Dealing with the Future](https://reader034.vdocuments.net/reader034/viewer/2022042610/568c52c11a28ab4916b7f52c/html5/thumbnails/8.jpg)
• Do we need the real threats, before
we change or respond?
• Should business do it in their own
long-term interest of survival or
because they get subsidies and
incentives?
![Page 9: Dealing with the Future](https://reader034.vdocuments.net/reader034/viewer/2022042610/568c52c11a28ab4916b7f52c/html5/thumbnails/9.jpg)
• Change won’t come if consumers
don’t ask for the shift. So the power to
change finally rests among us.
![Page 10: Dealing with the Future](https://reader034.vdocuments.net/reader034/viewer/2022042610/568c52c11a28ab4916b7f52c/html5/thumbnails/10.jpg)
• 3% of India’s landmass
• 40% of her people
• 75% of her natural resources
• 62% of GDP
• That’s our cities. Parasites that
corrode our larger ecosystems
![Page 11: Dealing with the Future](https://reader034.vdocuments.net/reader034/viewer/2022042610/568c52c11a28ab4916b7f52c/html5/thumbnails/11.jpg)
• 3K calories a day … Current Sun
provides.
• 225,000 calories a day is our
current urban per capita.
• All the rest of energy comes from Coal,
Oil, Gas… or the Ancient Sun.
![Page 12: Dealing with the Future](https://reader034.vdocuments.net/reader034/viewer/2022042610/568c52c11a28ab4916b7f52c/html5/thumbnails/12.jpg)
• India comprises just 2.4% of the
world’s inhabitable geographic
spread.
• We support 17% of the world’s
people.
• 3600 Urban Agglomerations,
towns and cities
![Page 13: Dealing with the Future](https://reader034.vdocuments.net/reader034/viewer/2022042610/568c52c11a28ab4916b7f52c/html5/thumbnails/13.jpg)
• India’s GDP is at US$ 1.7 trillion.
• It took 62 years to reach this level.
• The next Trillion Dollars will be reached in
next 15 years.
• The future is yours to take, shape and
hold.

6 strands of green living
Material – Materials that make for passive
Cooling and Heating
Water – ‘Grid-free’ water
Waste – Efficient waste management
Air – With 30% of regular cost
Energy – Reduced (Zero, if possible) dependence
on grid
Biomass – Micro-climate based landscape

• Reduced water consumption of 105,000 litres a
year. Reduces fresh water demand, raises water
security.
• Power consumption
– Dependence on grid is only 20% for entire campus.
Reduces 5,000 units a year and hence Rs. 15000 per
year
– Each house gets a local grid with a combination of
solar/wind and energy storage.
Campus Maintenance cost falls by half thanks to the
efficient energy and water management systems.
You can save about Rs. 1.0 lakh / year

ZED SALT-TO-WATER
Converts 80 liters of salt water to 20 liters of fresh, potable water.
Makes water naturally for a pure clean taste. Distilled water from the
store or from electric distillers relies on boiling water, which leaves the
water with a flat taste.
The Zed distilled water does not acquire the "flat" taste of commercially
distilled water since the water is not boiled. The Zed Distiller uses a
natural process.
