Yellow and green autorickshaws are ubiquitous on New Delhi's roads but Mahendra Kumar's vehicle stands out -- it has a garden on its roof aimed at keeping passengers cool during the searing summer season. Kumar says the thick patch of green keeps the vehicle cool even when temperatures are touching 45 degrees Celsius (113 Fahrenheit) in the Indian capital, enough to melt the tar on roads. Kumar, 48, has grown over 20 varieties of shrubs, crops and flowers, attracting commuters and passers-by who stop to click selfies and photos of the unique "moving garden".
