"Pond Scum" to Power Venice

It's known as "Serenissima," "Queen of the Adriatic," "City of Water" and as I call it, "the City of Slime;" but now Venice has an energetic plan to power its town, and deal with its plaguing algae problem. Read below, or be lazy... and check out the link:

Italy recently announced a 200 million euro eco-friendly project to harvest the prolific seaweed that lines Venice’s canals and transform it into emissions-free energy. The idea is to set up a power plant fuelled by algae, the first facility of its kind in Italy. The plant, to be built in collaboration with renewable energy services company Enalg, will be operative in two years and will produce 40 megawatts of electricity, equivalent to half of the energy required by the entire city centre of Venice.

The algae will be cultivated in laboratories and put in plastic cylinders where water, carbon dioxide, and sunshine can trigger photosynthesis. The resulting biomass will be treated further to produce a fuel to turn turbines. The carbon dioxide produced in the process will be fed back to the algae, resulting in zero emissions from the plant. “Venice could represent the beginning of a global revolution of energy and renewable resources. Our goals are to achieve the energetic self-sufficiency for the seaport and to reduce CO2 emissions, including those one produced by the docked ships”, says the president of the seaport of Venice Authority, Paolo Costa.

Major Breakthrough for Algae Growth to Benefit Biofuels

Bionavitas recently announced a new technology, Light Immersion Technology (LIT), that ignites Algae into rampant growth. Algae is the warlord biofuel and it's easy to grow; a major hurdle is getting it to grow in meaningful quantities, because as it grows, it becomes denser and blocks out needed sunlight to aid scalable growth.

Bionvavitas' new Light Immersion Technology is geared to solving just this. Read below:

Algae, shown to have the potential for solving the reliance on fossil fuels for energy production, are widely recognized as an important source for biodiesel production. Harnessing the power of the sun or an artificial light source by immersing it in the culture, Light Immersion Technology effectively produces an order of magnitude more algae biomass than existing growth methods, thereby increasing yields and reducing the cost to make algae-based biofuels price competitive with petroleum products.

Algae are the ultimate feedstock for biofuel production, promising yields that are hundreds of times greater than those of traditional land-based oil crops such as soy beans or rapeseed (canola oil). The dramatic yields depend upon the efficient use of solar energy not possible using previously existing technologies. Before Bionavitas made its Light Immersion Technology available to the public, nearly every large scale approach to algae growth has been challenged by a simple fact of nature: as algae grow, they become so dense they block the light needed for continued growth.

This “self-shading” phenomenon results in a layer that limits the amount of algae per acre that can be grown and harvested. The Light Immersion Technology developed by Bionavitas fundamentally changes this equation by enabling the algae growth layer in open ponds to be up to a meter deep. This represents a 10 to 12 time increase in yield over previous methods that produced only 3-5 centimeters of growth.


Bringing light to algae...

At the core of Light Immersion Technology is an innovative approach at bringing light to the algae culture in both open ponds and closed bioreactors through a system of light rods which extend deep into the algae culture. By distributing light below the surface “shade” layer and releasing the light in controlled locations, algae cultures can grow denser. In external canal systems, the rods distribute light from the sun into the culture. This abundant and free energy source is ideal for generating large amounts of algae for use as biofuels.

In closed bioreactors, the rods evenly distribute more readily absorbed red and blue spectrum light from high efficiency LEDs. While the LEDs increase the cost of production, algae grown in these systems are used for higher value markets such as nutraceuticals.

Brazil Wants U.S. to Lift Ethanol Tarrifs

Flush with freshly discovered oil, already the world's largest exporter of ethanol, up and coming superstar, Brazil, wants the U.S. to lift its 53 cent a gallon tariff that safeguards its worthless corn-based ethanol:

Brazil's President Luiz Inacio Lula da Silva on Friday implored American businessmen to help convince the United States to lift the 53-cent-per-gallon import tariff it places on his country's ethanol fuel.

Speaking at a Wall Street Journal-sponsored investor forum Monday, Silva defended the gasoline alternative as a cheap and easy way to end dependence on foreign oil and help reduce global poverty.

[...]

But Silva, who met with President Barack Obama on Saturday, has made little progress persuading the U.S. to reduce the tariffs, which are in place to protect American farmers who make ethanol from corn. Brazil makes ethanol from sugar, in a process that is much more efficient and costs less.

"One thing that leaves me perplexed, is in the same world where we invest in environmental policy capable of avoiding global warming ... many countries still don't place any tariff on polluting fuels while they place absurd tariffs on ethanol," Silva said, pointing out the ethanol burns relatively cleanly compared to gasoline.

During the presidential elections, Obama supported subsidies for the Midwest-based ethanol industry.

That support is widely considered a factor in his victory at the Iowa cauceses which boosted his early prospects during the primary. It also contributed to his victory in the general elections against John McCain, who opposed the subsidies.

In Brazil, all gasoline is blended with 25 percent ethanol and so-called "flex-fuel" cars can run on either the gasoline-alcohol mix or pure ethanol available at about 35,000 filling stations across Brazil.

About 23 percent of Brazil's automotive fleet is now "flex-fuel."


Added note: oil from their super deep finds (20,000 feet below sea and ocean floor) should start squirting by May 1. Mark it on your calenders.
