Penghemat daya listrik pada lampu

Cavet Technologies mengembangkan piranti penghemat daya listrik yang bisa menghemat daya sebesar 30%-40%.
Piranti tersebut bekerja dengan memutus-sambung daya listrik pada lampu selama beberapa nanodetik, yang karena cepatnya tidak akan terindera oleh manusia. Cara itu seperti algoritma kompresi MP3, yang mana bit tertentu dihilangkan untuk mengurangi ukuran file tetapi tidak merusak kualitas suara yang dikompresi secara berlebihan.

Tonji University Shanghai’s Bambu House at the European Solar Decathlon is a beautiful sun-powered abode inspired by nature. It has two elegant sloping roofs and is almost entirely constructed from bamboo. Its impressive solar array generates 9 kilowatts of electricity which powers its one bedroom, one living room layout. We love how the house combines traditional Chinese architecture with state of the art technology — it has temperature and humidity control systems, high-level thermal insulation systems, and a bamboo enclosed garden.

Tonji University’s team has 20 members and is composed of doctors, postgraduates, and undergraduate students who range across many disciplines — from architecture and urban planning to energy development. They hope that their solar-powered house can help promote their forward-thinking ideas about renewable energy use in residential urban areas. The team has spent six months designing and constructing the house from scratch and they are hoping their hard work will pay off. Structurally, the house is strongly influenced by traditional Chinese architecture but with a tinge of the efficient look of contemporary architecture.

The Solar Decathlon Europe kicked off with a bang today and Inhabitat is on the scene to provide a first peek at the amazing sun-powered architecture on display. The European Solar Decathlon is the sister of the US Solar Decthalon — which we covered in Washington DC this past October — and was organized in a partnership between Government of Spain’s Ministry of Housing and the United States Government. The decathlon is taking place all through next week in Madrid, so stay tuned to Inhabitat as we bring you a front seat view of all the action!

Portable Light

Link: Portable Light

More than 2 billion people live without electricity, most in extreme poverty. The Portable Light Project creates new ways to provide renewable power in solar textiles that can be adapted to meet the needs of people in different cultures and global regions.

Portable Light textiles with flexible solar materials and solid state lighting enable the world’s poorest people to create and own energy harvesting bags, blankets, and clothing using local materials and traditional weaving and sewing techniques in an open source model. Portable Light enables people in the developing world to benefit from flexible solar nano-technology and accelerates the movement to clean energy worldwide.

Flat parabolic mirror is not an oxymoron!

Link: Flat parabolic mirror is not an oxymoron!

Everyone knows what a parabolic reflector is, right? It’s supposed to be a curved surface that collects energy by converging it towards a focus. Parabolic reflectors were invented a very long time ago and have been used in satellite dishes, spot lights and car headlights to name a few. They are also widely used for alternative energy projects to concentrate solar energy for heating and cooking.
Dominic (designer of the flexible solar vest, the solar dryer, and camel milk cooler for Somalia) thinks that the parabolic mirror should lose it’s shape which is an obstacle, to transportation and function.

So how does the flat parabolic mirror work? Dominic has cut inch wide 2 foot long pieces of flexible acrylic mirrors and arranged them at specifically computed angles. When angled towards the sun, this creates a perfectly focused beam of light.

Vermont school builds net-zero field house

Link: Vermont school builds net-zero field house

By definition, net-zero energy buildings generate as much energy as they consume over the course of a year, and that’s at the heart of the Putney School’s 16,800-square-foot athletics building, which opened its doors last fall. Designed by Maclay Architects, the super-insulated, super-energy-efficient building uses the sun for its heating and electricity needs. Specifically, 16 sun-tracking photovoltaic solar panels power the building, feeding excess energy during sunny months back into the grid and earning the school 6 cents per kilowatt-hour as they do. In the winter, the building draws energy out again, but in an average year, it’s expected to do better than break even on its energy use. Other green features of the USD 6 million field house, include low-water fixtures and composting toilets, a white reflective roof and local materials such as site-harvested wood.

IBM Predicts 5 Ways Cities Will Become Smarter in 5 Years

[Prediction 1] Cities will have healthier immune systems

Given their population density, cities will remain hotbeds of communicable diseases. But in the future, public health officials will know precisely when, where and how diseases are spreading—even which neighborhoods will be affected next. Scientists will give city officials, hospitals, schools and workplaces the tools to better detect, track, prepare for and prevent infections, such as the H1N1 virus or seasonal influenza. We will see a “health Internet” emerge, where anonymous medical information, contained in electronic health records, will be securely shared to curtail the spread of disease and keep people healthier. …

[Prediction 2] City buildings will sense and respond like living organisms

As people move into city buildings at record rates, buildings will be built smartly. Today, many of the systems that constitute a building—heat, water, sewage, electricity, etc.—are managed independently. In the future, the technology that manages facilities will operate like a living organism that can sense and respond quickly, in order to protect citizens, save resources and reduce carbon emissions. Thousands of sensors inside buildings will monitor everything from motion and temperature to humidity, occupancy and light. The building won’t just coexist with nature—it will harness it. This system will enable repairs [to be made] before something breaks, emergency units to respond quickly with the necessary resources, and consumers and business owners to monitor their energy consumption and carbon emission in real time and take action to reduce them. Some buildings are already showing signs of intelligence by reducing energy use, improving operational efficiency, and improving comfort and safety for occupants. …

[Prediction 3] Cars and city buses will run on empty

For the first time, the “E” on gas gauges will mean “enough.” Increasingly, cars and city buses no longer will rely on fossil fuels. Vehicles will begin to run on new battery technology that won’t need to be recharged for days or months at a time, depending on how often you drive. IBM scientists and partners are working to design new batteries that will make it possible for electric vehicles to travel 300 to 500 miles on a single charge, up from 50 to 100 miles currently. Also, smart grids in cities could enable cars to be charged in public places and use renewable energy, such as wind power, for charging so they no longer rely on coal-powered plants. …

[Prediction 4] Smarter systems will quench cities’ thirst for water and save energy

Today, one in five people lack access to safe drinking water, and municipalities lose an alarming amount of precious water—up to 50 percent through leaky infrastructure. On top of that, human demand for water is expected to increase sixfold in the next 50 years. To deal with this challenge, cities will install smarter water systems to reduce water waste by up to 50 percent. Cities also will install smart sewer systems that not only prevent run-off pollution in rivers and lakes, but purify water to make it drinkable. Advanced water purification technologies will help cities recycle and reuse water locally, reducing energy used to transport water by up to 20 percent. …

[Prediction 5] Cities will respond to a crisis—even before receiving an emergency phone call

Cities will be able to reduce and even prevent emergencies, such as crime and disasters. IBM is already helping law enforcement agencies analyze the right information at the right time, so that public servants can take proactive measures to head off crime. The Fire Department of the City of New York has selected IBM to build a state-of-the-art system for collecting and sharing data in real time—to potentially prevent fires while protecting rescuers. IBM is also designing smart levee systems to prevent cities from devastating floods.”
