Going Electric

The New York Times publishes selected articles in a concise supplement which we receive every Saturday, here in Mumbai, India.
I have come across two very interesting articles on energy efficiency in modern day vehicles.

The current blog entry is picked from the following article - 'To help car buyers think electric, a better battery'.

The question - what can be done to make electric vehicles the choice of future auto purchasers? The answer lies in, improved battery manufacturing technologies which would reduce cost, enhance battery life and increase per kilo meter of kilowatt vs gasoline range. This would culminate to a shift in consumer tastes and expansion of the alternative fuels market.

Lithium-ion batteries in vehicles with scope for further research and innovation would prove acceptable at a mass level in a decade's time. Lithium being blended with various materials could result into a higher voltage  and increased energy density. This would prove in releasing such batteries off their greatest drawback, the battery life.



As per cost, currently, an electric vehicle would cost $750-800 per kilowatt an hour. In order to facilitate a parity between gasoline powered vehicles the cost must come down to $200 per kilowatt-hour.

India, has shown the potential to launch electric vehicles. As per current electric vehicle standards globally, India must largely invest into research and development in this field and must understand the potential of such technology.

Such is the scope of going electric.

Delhi Metro - 100,000 tonnes at a time


Only yesterday I returned back to Mumbai from Delhi.
Here is a video of the DMRC project of the Delhi Metro.

The Delhi Metro Rail Corporation helps in preventing 100,000 tones of CO2 emissions from emitting into the air, annually. It runs across a distance of 190 kilo meters and connects areas very effectively.

It is a blessing for the 2 million daily commuters.
