World's cheapest car an 'environmental disaster' for India

You know, the cities with the highest density number 3 till to number 7, are cities of India. Three interesting reports about congestion in India.

I read it accidentally on ABC news and I took it complete in our blog, because I don't know how long will it be readable (we have some links, which doesn't more working because the report was deleted).

Anyway, the link is http://www.abc.net.au/news/stories/2008/01/11/2136595.htm and if it doesn't work the report is below.

Something akin to a motoring revolution has been unveiled in India - a compact car that will sell for a little over $2,500 when it hits the market later this year.

The makers of the Nano believe it will revolutionise how India's 1.1 billion people get around, but critics say it will be an environmental disaster in a country already plagued by chronic air and noise pollution.

The theme from Stanley Kubrick's 2001: A Space Odyssey played as the Nano was unveiled at the annual Delhi car show by Ratan Tata, the head of India's industrial giant Tata Industries.

"We are very pleased to present these cars to you today," he said.

"They are not concept cars, they are not prototypes. They are the production cars that will roll out of the single plant later this year."

At three metres long, 1.6 metres high and 1.5 metres wide, the Nano lives up to its compact name.

It is a four-door, rear-wheel drive with a two-cylinder gasoline engine that claims to offer 20 kilometres per litre.

But the biggest attraction is not performance, it is price - 100,000 rupees - a little over $2,500 before on-road costs.

The target market is the many million of Indians who currently use a motorbike for family transport.

Environmental concerns

Still, many months before the car becomes available, potential buyers on the streets of New Delhi seem easily sold on the idea.

"Those people who are riding motorcycles these days can drive a car and they will find it easier to drive a car in the streets," one Indian man said.

"Everyone can afford this car."

The prospect of the Nano's popularity scares environmental campaigners in India, Centre for Science and Environment spokeswoman Anumita Roychowdhury said.

"There is just no room left for more cars in Delhi. If you really look at the city, the roads are already congested," she said.

"Data shows that we have even gone beyond the designed capacity of the roads.

"The traffic speed has come down drastically from 35 to 40kph to 12 to five kph [at] the peak traffic volume.

"Now that clearly brings out the fact that it is a crisis that we need to deal with, because [of] both the congestion and pollution impact.

"This cheap motorisation that is now going to explode in Indian cities, we are not prepared for it at all."

The Nano is the brainchild of Mr Tata, the 70-year-old head of the family company. And the old man bristles at criticism the car may not be eco-friendly.

"We may as well come to grips with the fact that all the things that you ask for may not be in a one-lakh (100,000 rupees) car and all the things that might be there in an eco car, may not be possible for one lakh," he said.

"Take it as it is. It's a car that's affordable, provides transport, meets all safety laws, meets all emission laws present and future.

"[It] will be a reliable form of transport which will provide Indian families an all-weather means of safe transport."

But it is not just the Nano for India. In two or three years' time, Mr Tata wants to roll out export version of the Nano to developing countries around the world.

An Holistic Approach



Following several meetings discussing the various collaborators views and different solutions for the pressing problem of city congestion and on-gong depletion of resources, it seems apparent that no one solution is likely to address the problem and that an holistic approach is most likely to develop integrated concepts with real life applications.
My investigations have focused primarily on vehicles and I have found a number of interesting sites on electric hub motors. Hub motors are available as a simple bolt on conversion for standard bicycles through to sophisticated applications as with this mini which uses hub motors to create a hybrid car that can achieve impressive results as shown.

Item
Original target specification
Emissions Zero

Autonomy 1500km
Top speed 200kph minimum
Acceleration 0-100kph in 6 secs
Braking No mechanical brakes
Fuel Zero carbon
BHP 250 bhp minimum

Current specification
Emissions zero for 4 hours

Autonomy 1500km
Top speed 240kph
Acceleration 0-100kph in 4.5secs
Braking No mechanical brakes
Fuel Carbon neutral option
BHP > 640 bhp


The issues with electrics are obvious however; the need for charging large banks of batteries over a long period of time may make them unattractive. Perhaps it is the charging process that should be looked at. If this mini can use regenerative braking to assist with battery charging, maybe the same process could be applied to other wasteful braking systems such as lift brakes in multistory buildings. If some key large companies that required delivery services were to collaborate to provide battery banks for small delivery vehicles, low batteries could be swaped with batteries charged from energy that would have been wasted and be providing a delivery service for the building itself. Battery technology is moving forward and smaller, faster charging efficient batteries are on the horizon.
