About 100 kg of wet waste should produce 4.5 kg of biogas a day, enough to run a community kitchen, reckons Hariharan. T-Zed’s central air-conditioning has been specially designed by BCIL and is free of the ozone depleting CFC and HCFC. “We have gone back to the post-war technology of ammonia serving as refrigerant. Ammonia is a benign chemical and is risk-free in home settlements,” explains Hariharan. Residents get fresh air from this airconditioning system and pay only Rs 4 or Rs 5 per hour of usage as compared to Rs 9 or Rs 10 per hour for the regular air-conditioner. Streets within the T-Zed area are lit with CFLs and LEDs. Late at night, the CFLs go off, further conserving energy. Each family earns Rs 12,000 a year in the form of carbon credits.
