That's for autorickshaws, which are closer to a motorcycle than an automobile.<p>The fuel economy quoted in the article (40km/kg) is around twice that of my Civic GX (30mile/GGE=30mile/5.660lb=30mile/2.567kg=51.5km/2.567kg=20km/kg), which is consistent with motorcycle numbers.<p>They also quote an autorickshaw traveling around 100km per day. Since the Civic with an 8GGE tank has a 400km range, the autorickshaw tank would need to be 1/16th the size. Assuming tank costs are linear and a new 8GGE tank is $3k, that puts the rickshaw tank at under $190.<p>I suspect the non-tank portion will also scale at least linearly with number of cylinders. Assuming a single-cyclinder motorcycle engine and 4 cylinder car, that runs the price up to $4k total, which, unsurprisingly, is still cheaper than here in the US but not by $10k.
