The CHIP House – which stands for “Compact Hyper-Insulated Prototype” – was started with the goal of creating a net-zero energy home (i.e. one that requires no external energy source), and it looks like the designers exceeded that target. The house actually generates three times as much energy as it uses thanks to solar panels and a host of energy saving measures.
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.”
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.
As we know it
One of the biggest concern for everyone today is to recharge the many small gadgets that have become an irreplaceable part of life. While these gadgets ensure connectivity with the larger world and allow you to go to places without worrying for any job undone or on an expedition, they also consume a lot of electricity for recharging. This becomes a constraint, especially when you are planning for a long vacation at some unexplored locations. As such location may not have regular electricity supply and you may get actually cut-off from the world during your journey. However, a few researchers have developed portable devices that you can carry along with you. They mostly depend on the renewable solar energy for recharging your gadgets. Also, they allow you to stop using conventional batteries that often contain harmful chemicals which get mixed with the soil and water when thrown after use.
Sustainable and renewable energy sources has been the main source of various efforts on both designing as well as scientific levels. Over the years, the development in this field has been subtly pushing forward to more feasible as well as practical applications in offices, homes and also small outdoor efforts. The Solar Pod featured today, however, takes a step forward towards more commercial applications with an architectural twist. The pod came forward while working for greener solutions in context of not domestic but rather public gatherings which requires a certain degree of sophistication united to functional utility of stored renewable power. To bring alive such dreams and amalgamate futuristic power technologies to a greener aesthetic context, the Solar Pod brings forth a metallic flower facade lined inside with thin film solar collectors which symbolically holds forth the fruit for effective future replacement of fossil fuels.
Ascent Solar Technologies develops innovative, lightweight, flexible, thin-film solar photovoltaic modules (that’s a mouthful, I know — read it again). Ascent’s flexible CIGS solar panels are so innovative they were named one of TIME’s are designed to integrate with limitless applications, transforming unused surface area into a source of clean, renewable energy.50 Best Inventions of 2011, one of only six “green” inventions to make the list this year. The list is featured in the November 28, 2011 issue of TIME (which, somehow, is already online… oh, old media, how you amuse me).
I just returned from the Solar Power International (SPI) show, an annual event for the solar industry, and there were a few things I kept hearing over and over.
One was: “It’s simple: People can live better with solar.” The second was: “The price of electricity will rise over the next decade.”
Over the last 40 years, Americans have been fortunate to have largely consistent electric rates. But as utility providers need to replace aging systems and fuel costs rise, experts predict that homeowners will soon need to pay more for electricity.
Living skyscrapers? Not quite. While organic solar cells are one of several types of photovoltaics currently being explored, Scientific American reports that work is being done that could lead to windows acting as solar panels, by using a compound very similar to chlorophyll.
Chlorophyll, as we all remember from elementary school, is the green chemical in leaves that turns water and carbon dioxide to oxygen and glucose with the use of sunlight (through a horrible cycle learned once in bio class and then forgotten forever). A chemist by the name of Michael Graetzel of the Swiss Federal Institute of Technology thinks he can use it to build a better solar cell.
Young Melbourne-based inventor Edward Linacre has won the 2011 James Dyson Award, making it the second year in a row where the prestigious prize has gone to an Aussie. Linacre stole this year’s competition with his Airdrop irrigation concept that collects water from thin air. The Swinburne University of Technology design graduate was driven to transform an ancient cooling technique into a new sub-surface irrigation system, following the enduring Australian drought that saw high levels of farmer suicide along Australia’s Murray- Darling Basin.
The Airdrop irrigation concept is a low-tech design that uses the simple process of condensation to harvest water from the air. Utilizing a turbine intake system, air is channeled underground through a network of piping that quickly cools the air to soil temperature. This process creates an environment of 100-percent humidity, from which water is then harvested. The collected water is stored in an underground tank, ready to be pumped out via sub-surface drip irrigation hosing. The Airdrop design also features an LCD screen displaying water levels, pressure strength, solar battery life and system health.
We have run many stories in the past about urine being used as a power source, but this week scientists appear to have made a breakthrough discovery. A research team from Bristol have published the world’s first research paper on work that tests the viability of urine as a potential fuel for Microbial Fuel Cells (MFCs) that directly produce electricity.
