A Portuguese with Indian origins has invented a car device that will aid the driver in saving fuel, thanks to an illuminated sign on the speedometer that indicates, with precision, when a car reaches its optimum fuel usage.
Rajesh Pai won a Silver medal at Geneva’s International Ball, in the Transportation sector, having come up with a simple solution to a very complex problem. “It is a mechanism that is a friend of the wallet and also of the environment” said the naturalized Portuguese citizen, explaining that drivers using his ‘Green Pai Driving’ (GPD) device will be able to gain a further six percent mileage from their fuel.
Simply put, the GDP is a system that shows a slice of a circle on the speedometer, indicating the correct speed at which a person should be driving to reduce fuel consumption to a minimum, whilst also reducing CO² emissions.

It is great to hear that Indians too are doing their bit to improve mileage. Fuel efficiency is the new mantra that all citizens of the earth need to chant. I think that most car drivers world over will like the GDP on their cars. I think the title should have been 'Indian invents'.
i just hope that they can mass produce this. the fuel price is just killing me
Just signed up on the forum hope to stay long here
It’s funny that you finally spoke up! I have been waiting for someone to bring this out to the open! Anyway… nice post. I will be back.
