GREEN CAR<>
Sayan Biswas is inventing an unusual kind of green car: one that burns gas.
Biswas's vision is something of an outlier in the green movement.
The overwhelming consensus of experts is that fossil-fuel-burning motor vehicles,
which account for more than a quarter of the world's greenhouse-gas emissions,
must yield to electric vehicles (EVs), and as soon as possible.
But ASAP, it turns out, isn't soon enough.
Despite the rapid uptake in EVs in recent years,
barely one in seven vehicles on the road in the U.S. is expected to be all-electric by 2035,
and only half by 2050.
If the world is going to sharply curb vehicle emissions during the decades-long transition to EVs, reducing emissions from standard gas-operated vehicles is essential.
