Yes you can have it, my friend has one they use cow dungs to charge it, you can buy specially designed oven for it and gas lights with mantle as we use in petromax lights, govt gives loan and subsidy on it BEST OF LUCK Prof.Dr. B.Saraf. PhD

Well, I read about it but can you just go and use it? do you think it will become an alternative used widely? according to Wikipedia: "Biogas can be produced utilizing anaerobic digesters. These plants can be fed with energy crops such as maize silage or biodegradable wastes including sewage sludge and food waste."

it is one of the best alternative source of energy, this time, because other substitutes are going to degraded through time gradually increasing, like petrol, diesel, compressed natural gas (cng), png, solar energy is expensive and worthless during rainy season, and winters, in my maternal home, it was set up for more than 30 years ago, for cooking gas it was produced by cow and buffalo dung, its really very good for cooking food and other food materials, its also good various other resources
