Scientists in Singapore have developed a pee powered battery. People not familiar with gobar-gas will probably wrinkle their noses, but I think its neat. Practical uses might be limited though. The linked articles says they intend to use it to power biochips. AFAIK biochips already have a decent enough design which enables them to derive/harness power from external electromagnetic fields.
Coming back to gobar-gas. Why did the whole concept dwindle off? I am not sure how extensively it is used even in rural India nowadays, but my impression is that the use is decreasing. We are a country with the largest cattle population in the world. Put all the stray cattle to use! Might as well get some good old methane out of all of them huh?
