Brazil: PV must become more affordable | Algae | Scoop.it

 

Brazil's northeast region, especially its central areas, has the highest potential for solar energy generation, according to the new 386-page report, which is now in a process of public consultation at the Ministry of Mines and Energy until October 31. The average solar irradiation in Brazil ranges between 1,200 and 2,400 kWh per square meter per year

Germany Widens Global Solar Lead

Germany Widens Global Solar Lead | Algae | Scoop.it

 

Germany continues to outstrip the rest of the world in solar power capacity, and is adding new solar faster than any other country as well. According to the trade publication Solarserver, Germany Trade and Invest (GTAI), the nation's economic development agency, says that Germans installed 320 megawatts of photovoltaic (PV) capacity in August 2012, putting the nation's overall PV capacity above 30 gigawatts -- roughly 24 times California's current total solar capacity.

DNA sequencing splits identical looking algae into different species

DNA sequencing splits identical looking algae into different species | Algae | Scoop.it
For nearly 260 years -- since Carl Linnaeus developed his system of naming plants and animals -- researchers classified species based on visual attributes like color, shape and size. In the past few decades, researchers found that sequencing DNA can more accurately identify species. A group of single-celled algae -- Symbiodinum -- that live inside corals and are critical to their survival -- are only now being separated into species using DNA analysis, according to biologists.

 

"Unfortunately with Symbiodinium, scientists have been hindered by a traditional morphology-based system of species identification that doesn't work because these organisms all pretty much look the same -- small round brown cells," said Todd LaJeunesse, assistant professor of biology at Penn State. "This delay in adopting the more accurate convention of identifying species using genetic techniques has greatly impeded progress in the research of symbiotic reef-building corals, especially with regard to their ability to withstand global warming."

 

LaJeunesse and his colleagues looked at Symbiodinium that previously had been grouped together as subsets of the same species. They report their results in the current (Sept.) issue of the Journal of Phycology. They examined specific DNA markers -- identifiers -- from the organisms cell nuclei, mitochondria and chloroplasts. Even though the symbionts appeared very much the same, except for their size, genetic evidence confirmed that the two are different species altogether.

Endesa Pavilion by IaaC

 

While photovoltaic panels are typically used on roofs – an otherwise unused surface – the Endesa Pavilion proposes going a step further towards the implementation of green tech in commercial housing.

Thanks to its modular panels and inclined surfaces (which maximize sunlight impact), the pavilion is able to make the most of the energetic resources available. It can work as a testbed for informational grid technologies.

Dubbed the Solar House 2.0, the project was designed by IaaC with the support of Endesa. It will be on show at the Marina Pier in Barcelona for the Smart City Expo Congress, and for a year it will act as a meeting point for knowledge exchange.

Solar Energy's Future To Be Found In Nano Technologies?

Solar Energy's Future To Be Found In Nano Technologies? | Algae | Scoop.it

Researchers from North Carolina State University are the latest scientists to tackle this problem and claim they’ve found a way of creating much slimmer thin-film solar cells, without compromising the cells’ performance.

The design of the new cells, according to the scientists, features what they’ve termed a “nanoscale sandwich,” which is unlikely to be very tasty but does deliver a tasty cost reduction via an ultra-thin active layer.

Urban Sustainability: The cities of the future will be grown, not built...

Urban Sustainability: The cities of the future will be grown, not built... | Algae | Scoop.it

 

At DLD Cities in London, he said "cities have centers that celebrate previous centuries -- in Europe, the cities celebrated spirituality, with cathedrals. After some time, the cathedrals became downtown cores- and celebrations of capitalism and commercialism".

The cities of the future will celebrate "the belief of what keeps us alive" - or elements of the city that make our lives better.

 

Terreform ONE, a green design company in Brooklyn, explores biohacks for the ecological issues facing modern cities. For instance, the waste New York City produces every hour weighs as much as the Statue of Liberty - in the future that waste could be recompacted into building blocks, or recycled "bales". Looking beyond recycling, though, it would be even better to create a city which didn't produce waste in the first place...

That means growing thousands of homes -- building a new suburb could involve twisting, pruning and manipulating large trees into the frames of buildings. "There would be no difference between the home and nature -- it would be something that would be a positive addition to the ecology," explained Joachim.

This new wave of technology that is being used and introduced to society is amazing! I never thought that they could expand into the sea but it is definetly something that could be to the benefit of those who work in the field. Also, it is a great way to create lessons for children and adults on how to protect our oceans from waste. They get a glimpse as to what lies beneath the surface. Raising the bar everyday. Thank you for this article!

The Outlook for Energy: A view to 2040

The Outlook for Energy: A view to 2040 | Algae | Scoop.it

In 2040, what types of energy will the world use, and how much? How will new technologies, efficiencies and policies impact the market?

The electricity generation sector is essential to meeting modern energy needs. Utilities and other electricity producers transform different types of primary energy – everything from natural gas to coal to wind and hydroelectric power – into electricity to be used in homes and businesses. Through 2040, global demand for electricity will continue to rise steeply, as the fuels used for electricity generation continue to shift to lower-carbon sources, such as natural gas, nuclear and renewables.

New processes for cost-efficient solar cell production

New processes for cost-efficient solar cell production | Algae | Scoop.it

The competition in the photovoltaics market is fierce. When it comes to price, Asian manufacturers are frequently ahead of the competition by a nose. Now, Fraunhofer researchers are designing new coating processes and thin layer systems that, if used, could help to reduce the price of solar cells significantly - and give the competitive edge back to German manufacturers, too.

The photovoltaic industry is pinning its hopes particularly on high-efficiency solar cells that can achieve efficiencies of up to 23 percent.

Striking, Yet Noninvasive Hydroelectric Power Plant Design in Italy | Extreme Architecture | News, E-learning, Architecture of the future at news.arcilook.com | Algae | Scoop.it

Being used to imposing, concrete buildings often defy their landscape in order to transform its energy, this ‘Hydroelectric power plant Punibach’ came as a pleasant surprise. Envisioned and implemented by Italian practice Monovolume Architecture, the project has a noninvasive visual appearance, keeping a low profile in its beautiful alpine enthronement in he South Tyrol province of Italy. A concrete slab rammed into the ground acts as a separator between the landscape and the various practical machines inside. Made up of natural, earth colored materials, the new structure is of interest not just due to its functionality, but its aesthetics as well. The wooden lamellar facade is an eye-catcher for passers by, making the building easily recognizable during the day and night, when light glows through the numerous small fissures. Curvy lines are elements that contribute to the inconsequential impact of the site, while transforming the building into a modern local landmark.
