Eco-friendly Living – Act Now

By | 2017-03-28T08:43:44+00:00 March 26th, 2016|City Smart, Energy, Green Tech|0 Comments

Why it is absolutely imperative to make changes to our current lifestyles The reason is simple. We have exhausted all options and the only way out is, to shape up or ship out. Dramatic as it might sound, we are in danger of wiping ourselves out from the face of the earth, if something is not done about environmental degradation. Most of the recent flooding, forest fires, and landslides can be attributed directly to unbridled human activity. The recent Chennai floods is a case in point. The devastating loss to life and property is mind-numbing. Danger signals: Melting ice The [...]

How Green Really is Your ‘Green’ Home?

By | 2017-03-28T08:43:46+00:00 March 25th, 2016|City Smart, Energy, Green Tech|0 Comments

What makes for a green home in reality? Oftentimes, what you get sold is not what you want, or at least, not the exact thing you want. Asterisks and other typographical symbols come in handy for sellers who are unable to match their sales pitch with actual delivery of goods matching the promised specifications. It always pays to go through sellers’ claim with a fine tooth comb and linger on fine print until you are reasonably satisfied with what you are getting. In most cases, the discrepancies may be as acceptable as the difference between a lime and a lemon. [...]

Benefits of Rooftop Gardening

How does the food we eat end up on our dining table? Young kids might be forgiven for thinking food actually grows in supermarkets. Only if it were that simple. So what steps are involved until the food ends up on your table and how does it impact environment during the journey? The concept of food miles is used to assess the environmental impact from the time of production of food until it reaches the consumer. Farming sector in crisis The distress in the farm sector owing to factors like excess rainfall, unavailability of farm labour, crop failure, and lack [...]

Advantages of Owning a Vacation Home

The opinion is evenly divided among the general population on the subject of buying a second home. While some recognise advantages such as a chance at savings on hotels and resorts and other weekend getaways, others are not so enthused about the idea. Most folks brought up in middle class homes would do a double take at the thought of splurging money on such a grand scale. But is it really an extravagance? Let’s find out. It begins to make sense Like most things in life, truth lies somewhere in between. When examined impassionately, the idea of owning a second [...]

This fruit can be future fuel

By | 2014-10-06T06:34:17+00:00 October 6th, 2014|Green Tech|0 Comments

In the early 1980s, when scientist Willie Smits was courting a native Indonesian woman of a mountain tribe of Sulawesi, who he later married, he stumbled upon a solution for the rainforest destruction in Indonesia hidden in the tribe's traditional culture. He had to pay a dowry of six sugar palms before the wedding. It had seemed like little to him then, but later, reflecting on the actual value of the Arenga Pinnata, he hit upon a possible solution for restoring Indonesia's rainforests. "The palm juice chiefly consists of water and sugar—made from rain, sunshine, carbon dioxide and nothing else," [...]

Biofuel Beginnings

By | 2014-10-06T06:33:50+00:00 October 6th, 2014|Green Tech|0 Comments

It was a few years ago that the world suddenly realised the potent threats caused by fuel consumption, and the alarming rate at which it was going then—carbon emissions into the atmosphere, as well as depletion of its sources. Biofuel was recommended as a workable alternative by a number of environmentalists. That was the late Eighties. European countries raced with each other to replace as much of their petroleum as possible with more 'sustainable' fuels. While appearing to be a sensible step towards softening the hurt for the planet, it actually had the reverse effect: massive areas of rainforest across [...]

Make the freezer work smarter

By | 2014-09-15T06:43:11+00:00 September 15th, 2014|Green Tech|0 Comments

Think about it: the refrigerator only senses the temperature of the air in the fridge, not the food. Every time it is opened, the air becomes warmer immediately, while the food may not warm much. You can imagine the unfortunate result: the compressor works overtime to cool the already cold food. How do we overcome this? The E-cube is a three-inch-across wax cube designed to fit around the temperature sensor of a fridge, mimicking the temperature of the food in it, so that the compressor is triggered on only when the food starts getting warmer. The ecube technology simulates the [...]

Why biodiesels aren’t viable

By | 2017-03-28T08:44:35+00:00 September 1st, 2014|Green Tech|0 Comments

Biodiesel. Biofuels. Jatropha. Ethanol. We get to read about them often, but why don’t we see them being used more widely? The issues: 1. Edible oils in India are in short supply. 40% of our stock is imported. 2. Even though a large quantity of edible oil is consumed, availability of used cooking oil is low since it is used as much as possible! 3. Collecting seeds to produce oil is a nightmare. The seeds have to be collected manually. In one day, a person can collect 80kg of seeds, from which 20-23 litres of oil is produced. Collection is [...]

Drive electric

By | 2017-03-28T08:44:37+00:00 August 31st, 2014|Green Tech|0 Comments

At nearly every auto show, there’s an electric vehicle or two getting some worthy praise, although usually, the gas-guzzling SUV or Ferrari is what steals the show. We don’t often get to see hybrid cars on Indian roads – the concept has not yet enough gathered steam here. Here’s a short guide to the types of energy efficient cars you can buy in the market: 1. Plug-in hybrids: These cars have a petrol engine in addition to a lithium ion battery pack – which you can charge with a battery pack, giving 36 to 80 km of electric range before [...]

China builds a Green Wall this time

By | 2014-08-30T06:25:55+00:00 August 30th, 2014|Green Tech|0 Comments

As desert sands claim fertilise lands nearly everywhere in the world, the Chinese have come up with an interesting solution: creating a forest belt stretching 2,800 miles (4,500 km) to block the advancing sands of the Gobi desert. They hope to put a brake on the severe sandstorms they face. Africa is looking for funds to build an ambitious "Green Wall" to hold back the Sahara. A Swedish architect suggests using bacteria that would solidify moving sand into rocks and build a wall to stop advancing sands. Sunseed Desert Technology, from Spain, has renovated abandoned 1,000-year old Moorish irrigation systems. [...]
