Scientists discover green way to produce steel

Closer scrutiny by NGO Centre for Science and Environment, however, shows the process is not quite as CO2 emission-free as claimed

Early in May, researchers at the Massachusetts Institute of Technology (MIT) announced the discovery of a new method of producing steel that is free of CO2 emissions. The process, known as molten oxide electrolysis (MOE), was initially employed to generate oxygen. The product generated was oxygen and, astonishingly, steel.

Solar energy not war

  If you know that a sector has arrived when it makes for trade wars between countries, then solar energy clearly has. Last year, the US imposed anti-dumping duties on Chinese imports of solar panels; now the EU has proposed the same. The Chinese have in turn threatened that they will take action against European exports of poly-silicon, the material used for manufacturing solar panels. In February this year, the US filed a case against India at the World Trade Organization (WTO) for “favouring sourcing of panels from domestic manufacturers”.

'Developing countries are treated in a very unfair manner'

Bernarditas Muller, a seasoned member of the Philippines negotiating team, is among the rare few who call a spade a spade. Speaking to Indrajit Bose during the ongoing climate talks at Bonn, she outlined the importance of the UN Framework Convention and provided insight into how the developed world represents the epitome of inaction and how some developing countries are still so naïve.

Ganga saga part II: redesign dams, not rivers

Engineers require re-training, not the Ganga. This is where I had left our conversation last fortnight. Why did I say this? The inter-ministerial committee I participated in as a member was discussing how much the ecological flow—the water that should be left in the river for ecosystem and livelihood purposes—should be at all times. How much water is needed for the river to be a river; and not a drain?

Training engineers, not Ganga

Hydropower is important. But how important? Is it important enough to dry up stretches of our rivers? Or is there a way to balance the need of energy with the imperative of a flowing, healthy river? I have been grappling with these issues for the past few months. But now that the committee (of which I was a member) on the hydropower projects on the Ganga has submitted its report, let me explain how I see the way ahead.

A green facade

Building green is definitely important. But equally important is to know how green is a green building. Take the glitzy, glass-enveloped buildings popping up across the country. It does not matter if you are in the mild but wet and windy climate of Bengaluru or in the extreme hot and dry climate of Gurgaon, glass is the in-thing. I have always wondered how buildings extensively using glass could work in such varied climatic zones, where one needs ventilation. Then, I started reading that glass was green. Buildings liberally using glass were being certified green. How come?

Wake up and smell the air

Our health is not on anybody’s agenda. Or, we just don’t seem to make the connections between the growing burden of disease and the deteriorating condition of our environment. We don’t really believe the science, which tells us each passing day how toxins affect our bodies, leading to high rates of both morbidity and mortality. It is true that it is difficult to establish cause and effect, but we know more than enough to say that air pollution is today a leading cause of both disease and death in India and other parts of South Asia.

Kumbh: time to come clean

Maha Kumbh in Allahabad has perhaps no parallel in terms of the sheer size of the congregation. In less than two months over 100 million people are expected to come to this city, which sees the confluence of two rivers of India—the Ganga and the Yamuna. People come to worship on the banks of the Ganga. Even as they celebrate the river it seems they don’t see the river, but only the ritual.
