Dust, dirt, and the occasional bird-bomb can chip away at the efficiency of solar panels. Hand washing is fine for home-scale installations but that can add up to a huge problem for large installations that cover multiple acres of ground or roofs. Now scientists from Boston University have come up with a solution: self-cleaning solar panels based on technology used in missions to Mars.

The project “Building Energy Efficient Biogas Cellars for Families in Phu Tho Province” was very successful. It was launched by the Phu Tho Center for Industry Promotion, Consultation and Energy Conservation, within the framework of the National Targeted Program on Energy Efficiency and Conservation.

A new joint venture research work at Stanford and SLAC National Accelerator Laboratory, supported by Department of Energy and DARPA has come up with a new solar energy conversion process that can potentially double the efficiency of solar cells. Stanford engineers have discovered this new and totally different process to harvest energy from sun.

In the 1990s, the solar energy technology was introduced into Vietnam through projects funded by the governments of Spanish, Dutch, French and German. Many solar energy projects have been put into application since then, mainly to meet electricity needs of people in remote and rural areas, where the national grid has not reached. Unfortunately, those above projects are only in pilot scale.

Ocean Renewable Power Company (ORPC), an industry leader in tidal, river and deep-water ocean current energy technology and projects, announced today that its Beta Power System, the largest ocean energy "power plant" ever installed in U.S. waters, has successfully generated grid-compatible power from tidal currents at its Cobscook Bay site in Eastport, Maine.

One purpose of developing solar power technology is to support the load for the national grid and enable consumers to use EVN’s electricity at peak hours with price of off-peak hours (price of grid electricity at night is only 500 dong per Kwh, while during peak hour it is about 2000 dong, calculated accumulatively).

When you think of electric cars, you generally mean two terms in which they exist: autonomy vs charging infrastructure. These two words compete with each other to a certain point, because higher autonomy means less infrastructure needed, hence faster adoption by the market.

This has led to the increased production of PV cells not only in Europe but also in Taiwan and china. China alone produces 2GW solar cells annually. In February 2010 the price of electricity using PV panel is $4.27 per watt. Today the price of photovoltaic cells of different companies is different. The General electric solar panel costs $ 228 to $385. This trend would decline with more competition.

In production of bricks with semi plastic technology, a specialized machine system is used to process the raw materials, mixing them together into a specific blend used for each particular type of product such as building bricks, roofing tiles or floor tiles. After that, the mixture is shaped and transferred to the kilns for burning.

The first building construction using non-fired building materials in Ha Noi is the Keang Nam 70-storied building. The owner of this project has transported the entire discarded constructional materials and soil from digging the foundation to Hue Quang Commerce and Technology Joint stock company (Hue Quang Company). This company will buy the discarded soil from Keang Nam to produce non-fired eco bricks and sell them back to Keang Nam. This is regarded as the model that sets the trend of using environment friendly materials in Vietnam.

DOE announced on July 22 the creation of the Fuels from Sunlight Energy Innovation Hub to develop revolutionary methods of generating fuels directly from sunlight. The Joint Center for Artificial Photosynthesis (JCAP), led by the California Institute of Technology in partnership with the DOE's Lawrence Berkeley National Laboratory, will operate the initiative.

Success greets the research team of National Research Council’s National Institute for Nanotechnology (NINT) and the University of Alberta. The plastic solar cells have now an operating life of 8 months instead of mere hours. And they are low-cost, environmentally efficient, unsealed plastic dollar cells – a green energy source.

The USC team's graphene organic photovoltaics, recently discussed in the journal ACS Nano, have a host of benefits: They're flexible, cheap to produce, are easy to manufacture, and they're light-weight. And while they're considerably less efficient than silicon cells, they offer unique applications.

Dubbed Plugless Power, the device makes use of proximity charging technology to power the vehicle. Evatran’s system works by using a shoebox-sized device mounted to the undercarriage of the vehicle and a parking block which also contains a transmitter that can move within the box and thus get as close as possible to the receiver on the vehicle.

Lawrence Berkeley Laboratory and the California Institute of Technology in Pasadena were selected to lead the ambitious research project, the energy department announced Thursday. Its aim is to master the basic science involved, and develop applications that can be scaled up for commercial use.

In the early July, in Ha Long city, Vietnam Academy of Science and Technology and the National Energy Efficiency and Conservation Program (VNEEP) cooperated with Quang Ninh People’s Committee to organize “Effective energy saving lighting models in Northern provinces” media event. The event will contribute to propagate policies and develop public highly efficient lighting models as part of VNEEP.

In 1995, Ha Long Brick factory stopped operating because the circular kiln technology was obsolescent. The company switched to operate Tieu Giao Brick factory with tunnel furnace technology granted by Bulgaria. With two tunnel furnaces using dust coal, work conditions and product quality were improved but still at a low level. The company decided to dismantle Ha Long Brick Factory to try the new technology: dry crushing – plastic extruding – quick drying to produce high quality tile.

RoseStreet Labs Energy Inc. (RSLE) reveals its IBand technology as the first successful attempt at multiband, high-efficiency photovoltaic solar.No, I'm not talking about a nifty cover for your Ipod Touch or some strange wristband that remembers who you've shaken hands with.

ATK, a company that builds the space shuttles’ booster rockets may have a solution for the massively-polluting coal power plants, by using rocket nozzle technology to turn the carbon dioxide into dry ice, and capture it easier than they can do with chemicals.

With advantages such as reasonable price, energy efficiency, high luminescence efficiency and high durability, diverse styles, LED (light emitting diode) products are becoming attractive to Vietnamese consumers.
