Smartphones of today

The world of cellphones is expanding with new models being launched almost every day. Back in 1973, when the first cellphone was made; it was a bulky object with not many functions other than that of making and receiving calls. Now, cellphones have become like mini computers with multipurpose cameras, capable of storing substantial amounts of data, recording videos and music, linking to the internet, playing games and a whole host of other features. These phones fall under the category of smartphones owing to their intelligent capabilities. So essential have they become to consumers that the third quarter of the year 2011 saw 115 million units of these phones being sold worldwide.

Denver-based New Town Builders have created a net zero energy house that has been designed to save a lot of energy and help preserve precious resource. The Zero Energy Home will leave eco lovers in a state of complete amazement as it takes energy efficiency to an all new scale.

The epic voyage of the Tûranor PlanetSolar – the world’s largest solar-powered boat – will soon come to a close as the ship closes in on its final stretch. The Swiss vessel is a full-bore high-tech solar harvesting machine whose deck is covered in 537 square meters of photovoltaic panels. The array produced enough energy for the boat to navigate the entire circumference of the Earth without any other means of energy. The Tûranor PlanetSolar is currently set to depart Abu Dhabi en route to their final port in Morocco – the same place the expedition launched on September 27th, 2010. The journey has come full circle in more than one respect, as it was not too long ago the only way to navigate the earth was by harnessing renewable energy with sails.

For those who like simplicity and wish to maintain a sober lifestyle, talented designer Lorenzo Giacomini has come out with a special lighting device, the QBIC Lamp. There is a variety of lighting products available in the market but QBIC Lamp is unique in the sense that it fulfills your simple and routine lighting requirements while taking care of the surrounding too. This is an eco-friendly device that runs on solar power. With its shape as of a small cube, this lamp may serve your needs just anywhere. You may easily carry it wherever there is sufficient sunlight.

A team of scientists from Seattle-based AltaRock Energy, Inc. and Davenport Newberry Holdings LLC has announced plans to harness one of Mother Nature’s most powerful energy sources by pumping 24 million gallons of water into the side of a dormant volcano in Central Oregon. The team hopes that the water will return to the surface boiling hot, at which point it can be used to generate clean and cheap energy – without the explosive side effects and liquid magma associated with active volcanoes.

The Maker Faire is a place where weird and wacky inventions are welcomed and championed, which is surely why Bob Schneeveis and Grant Grundler decided to debut their crazy solar powered electric chariot there. The chariot is a modern-day renewably powered take on the ancient Roman cart which is pulled around by a roller blading robot who glides with the greatest of ease. Video of the chariot in action after the jump.

There are many new technologies being developed to create cheaper, more efficient solar panels – however researchers at the National Renewable Energy Laboratory just announced that they have found a way to create more efficient photovoltaic cells using 50% less energy. The technique hinges upon a new optical furnace that uses intense light instead of a conventional furnace to heat silicon to make solar cells. The new furnace utilizes “highly reflective and heat-resistant ceramics to ensure that the light is absorbed only by a silicon wafer, not by the walls inside the furnace.”

We’ve heard of gadgets being powered by some pretty crazy stuff, but how about paper? Sony recently showed off a new bio-cell battery that breaks down paper in order to create power. A paper battery sounds a little bit far-fetched, but the technology works, and could potentially change how we power devices in the future.

With the big strides of green technology covering the recent years, we have come across some fascinatingly innovative concepts. But there are few even among them that have that essence of adroit practicality combined with inherent credibility. In simpler terms, these seldom conceptions have the potential to appeal to the common man, and benefit him on a large scale. In relation to this, in our book the intriguing yet uncomplicated piezoelectric energy harvester certainly falls under this exalted category. According to industrial designer Benjamin Wright, the project entails the usage of emerging materials to efficiently contrive a sustainable and efficacious end product.

The Japanese electronics giant Sony has announced the development of a new technology that produces energy from shredded paper.

At a fair about environmental products, opened in Tokyo, Sony invited children to make a little experiment. They introduced a paper into a mixture of enzymes and water. After a few minutes, the liquid has become a source of energy, being able to power a small fan.

A new efficiency record for organic photovoltaic cells has been reached by Heliatek, for the third time in a row. The German company created a cheap solar cell that can convert up to 9.8 percent of the incoming light into electricity.
