So according to google a 747 can through 36,000 gallons of fuel in a 10 hour trip. Being conservative and you only need half as much for 2 engines at full throttle, that means that you would need ~40K gallons of fuel a day?<p>Google tells me that jet fuel ranges from $4-$8 a gallon, therefore the operating costs for a single truck is around a quarter million dollars a day ($250,000)? Even if the operating cost is only 1/5 of this ($50,000 a day), that's 20 million dollars a year in fuel costs.<p>If India has 20 million a year to spend on fuel for this contraption, why wouldn't they just spend that money to clean up the power plants instead?<p>My guess is that the operating costs of this terrible idea are so large, they would hardly ever turn it on. I agree that this seems like a PR stunt rather than a real idea.
