Other institutes, such as the New Delhi-based The Energy Research Institute (TERI), are working on methane capture strategies. One long-running project has been biogas production — cow dung is utilized to make biogas for use in kitchens and even compressed biogas for use in vehicles. "Biogas plants have been very successful," says R.K. Rajeshwari, a fellow at TERI, "Farmers are able to use biogas in their kitchens, to light lamps and to even drive vehicles."

A research is beginning in Australia on this problem, with sheep included. Guess we'll have further genetic alteration of their makeup.
