If you were wondering how one could stay warm and cozy right on top of an ice-capped mountain, you must seek the advice of the Department of Architecture at the Swiss Federal Technical University. They have constructed the autonomous alpine shelter at a height of 2,810 meters above sea level. Many students and researchers have already started to use the facility and have spoken of its convenience and safety. They surely were awed, too, by its majestic perch on a snowy peak.

Situated right at the tip of a glacier, it is as remote and far away from any energy source as it could get. However, an innovative mind can take one a long way on the journey towards energy self-sufficiency. The building could be used by mountaineers as a base camp before making an ascent on the Alps.

The kind of megapolises we live in makes us wonder what is going to be like after a few decades. We may imagine crowded streets without enough space to move our toes. However, Nobel-Prize winner Dr. Daniel Kammen believes the cities can in fact be self-sustaining eco hotspots and can allow people to lead a healthier lifestyle than we do today.

Any of the polluting and energy consuming devices and technologies may be phased out and the cities would be blessed with cleaner air and water. Urban gardens could provide as an alternative to farm products, which strip the soil of its nutrients. Alternative fuels, good waste disposal systems, and also mass housing may help our future cities sustain themselves and not leave ugly carbon footprints. In fact, carbon footprints are left by each individual, even when one drives to the supermarket.

Imagine finding a light bulb which is more efficient, less polluting and comes with a facility of data transmit. If you thought I am talking in my dream, you ought to read on and find out that Researchers at Boston University’s College of Engineering are working on something completely amazing. They are believed to be working on a Wi-Fi replacement technology which they call “Smart Lighting” that sends data not via the radio spectrum, but the visible light spectrum. The agenda is to replace the standard dumb light-bulbs by LED “smart lights,” which work at imperceptibly high rates as a way to transmit data in a network which would turn out to be helpful within an office. This means the moment you tap a light on, you can access data on any device with wireless capability anytime without the use of wires. Researchers believe initial speeds would hit between 1 and 10 megabits per second.

It surely won’t get greener than this with Dell launching a “never before seen” eco-inspired computer with a bamboo casing. A machine which is 81 percent smaller than a standard desktop, uses 70 percent less power, is filled with recycled materials like old bottles, milk jugs and detergent cases and is still a computer- what more can one ask for?? Not willing to divulge the details of the name for this eco-friendly device, Dell’s CEO Michael Dell confirmed that the product would come out later this year and would likely have a price tagin between $500 and $700.

The industry has coined such phrases as “ecolutions” - short for the rather long-winded eco-friendly and environmental evolution and solutions - “cooler and cleaner,” and “hi-tech, low carbon” in its attempt to plug the message that emissions can be reduced without computer users having to sacrifice functionality or style. Use of similar products, he said, could reduce a family’s electricity bill by 40%. Calculated on the grander scale of a multi-national company, the savings could run into millions.
With such benefits to offer this one is going to be your hi-tech, eco-friendly purchase.

Now have an environment-friendly travel. In what can be treated as a step towards government’s endeavor to fight pollution by vehicles, Volvo announced the launch of its new entry into the diesel-electric hybrid bus market. The hybrid Volvo 7700 is a 12-meter low-floor city bus that gets up to 30 percent better fuel economy and emits 40 to 50 percent less nitrous oxide and 30 percent less carbon, the company said. In addition, a smaller engine and nearly a third of the bus’ components are developed in-house by Volvo.
The hybrid Volvo 7700 uses “parallel hybrid” technology which allows the bus to be powered by either the electric motor or the diesel engine or both at the same time. I-SAM, the company’s hybrid technology, plans to use the same technology in its trucks and construction equipment after the buses go into mass production in 2010. Though the hybrid bus weighs more or less the same as a diesel-driven bus, it has a better weight distribution, which allows the hybrid bus to take more passengers than a comparable diesel bus.� As a result, the bus’ performance is enhanced and fuel consumption is reduced.

According to a report by United Press International, the first of Volvo’s hybrid buses will begin testing on city streets in London and Gothenburg, Sweden, later this fall. Volvo is believed to start delivering hybrid diesel electric buses to customers in 2009 with mass production beginning in 2010.

With the benefits of Windmills come common concerns like the whooshing sound that regular turbines produce, as well as their divisive visual aesthetics. Keeping in mind the volatility of the speed of wind in the urban environment, the QR (Quiet Revolution) has been designed. A new type of wind turbine intended to address both of these issues, Quiet Revolution’s QR5 Vertical Axis Wind Turbine, or VAWT for shawt, is smaller, quieter, and way better looking than your typical windmill, plus it should produce the equivalent of its £25,000 price tag in clean energy within 15 years or less. The elegant helical (twisted) design of QR ensures a robust performance even in turbulent winds. It is also responsible for virtually eliminating noise and vibration.

At five metres high and three metres in diameter, it is compact and easy to integrate, and with just one moving part, maintenance can be limited to an annual inspection.

Though the energy output will vary according to the wind speed but is likely to be between 6,000 and 10,000 kWhrs on a typical site. And if that wasn’t all, according the usage of such windmills will also lead to reduction in CO2 emmisions.

With the West in a water crisis, it’s not surprising to see a machine that pulls water from ambient air at West Coast Green. Though not an innovation, these machines require a lot of energy which has been dealt with by Element Four who have addressed the issues of energy use for creating water. The unit uses just 300 watts; a relatively low amount for these machines, the Watermill senses its environment and acts accordingly.
The Watermill checks its environment every three minutes to determine the dew point and keeps itself operating at just a few degrees below that dew point. This way, it maximizes efficiency of the energy it uses to operate by maximizing the amount of water it can pull from the air 24 hours a day 7 days a week.
It can pull an average of 13 quarts of water each day, which is plenty of potable water for an average family of four. The water is essentially distilled, but a filter can be added to restore organic minerals if the user wishes.

And if that wasn’t all, a solar powered version of the machine is in the works and will be available in about six months. So, this one is sure to tackle the water needs and the environmental issues with utmost efficiency.
