I can only imagine how great will be for the Indian roads if our very own BEST buses could undergo such a Eco-revamp. Nothing better to start a green revolution than making a big difference to the public transport system, since there are still many people who travel only by public transport system. The design looks decent and the hydrogen is kept at a suitable place where it wont eat up space. The only concern is now the re-fuelling stations and i wish this issue is sorted ASAP so that we can see these nature buses on road as quickly as possible.
