Tongues have been wagging recently following reports that a team at the Barcelona Institute of Microelectronics in Spain had developed an electronic tongue -or a robot, if you like- that could easily pick excellent wines from a line of fakes.

The tongue was invented by Cecilia Jiménez-Jorquera and her colleagues at the famed institution and is reported in the Royal Society of Chemistry journal, The Analyst. She said of her innovation: “The device is based on similar principles to the human tongue and is sensitive to just five different tastes: sweet, salty, bitter, acidic and umami (savory).

Our results have demonstrated the potential of using multi-sensors as electronic tongues not only for distinguishing the samples according to the grape variety and the vintage year, but also for quantitative prediction of several sample parameters.”

Could these be “green” attributes of the new tongue, someone? It is said to be fast, portable, cheap to manufacture, and can be trained to “taste” new varieties as required.

As expected, since the reports, views and counter-views (over a glass of wine, of course) have been parlayed in hundreds of forums including blogs and even radio and TV talk shows in Spain but this certainly does not mark the death of the art of wine tasting.

The construction of  31 offshore wind farms, to be ready by the year 2012, is not being totally accepted by Spaniards.

People from Cadiz, Galicia and Tarragona, Spain, are not very comfortable with the project. The objection: offshore wind farms may spoil the view.

Certainly big wind turbines make the landscape uglier, not only in the mountains but also in the sea, at least if they are not well planned.

A new machine that pasteurizes milk by using solar energy was recently installed in Nicaragua, thanks to researchers from the Agrarian University of Nicaragua and Spain’s University of Lérida. The primary goal for the machine is to help communities to save money. With its use of clean energy, it will also help to curtail global warming and perhaps will eventually help Nicaraguans to start new businesses.

Right now, the machine is primarily used like a small factory to make cheese as well as other dairy products. It is currently housed in the Agrarian University of Nicaragua’s Department of Animal Sciences. Solar panels contribute the energy for a mechanical system that heats the milk to 185° Fahrenheit (85° Centrigrade). Approximately 240 liters of milk can produced in 6 hours using the prototype.

The machine’s arrival and its probable success is good news for Nicaragua and many other developing countries. The prototype was made from resources found locally, and will hopefully serve as a model for others who might want to make such a machine from easy to find materials. The design plans for the invention will eventually be made public via the internet.

Once again boosting their reputation as a country intent on helping the environment, Spain has announced that they intend to put 1 million electric cars on their roads by 2014. This will be part of the Zapatero government’s plan to reduce their use of energy and increase the countries overall energy efficiency.

Spain’s minister of industry, business and tourism Miguel Sebastian said Tuesday that the plan should gain approval from Spain’s Council of Ministers on Friday, and should then be carried out this year and on through to 2011.

Last week I reported on a story that saw a new bill passed in Hawaii making it mandatory for every new home to have their hot water powered by solar panels. Signed in to law by Governor Linda Lingle, the bill will require all single-family homes built starting 2010 to have a solar panel powering the hot water system.

However Hawaii isn’t the trend setters we may have first thought them to be.

Over at MetaEfficient.com, they have an article pointing to the fact that 90% of Israeli homes already have solar water heaters. It began in the early 1950’s when the Israeli government encountered a fuel supply shortage, and restricted the times when water could be heated. In response, the people decided that they would start heating their own water using solar panels.

Expo 2008, the international exposition on water and sustainable development, opened its doors to the world on Saturday in the Spanish city of Zaragoza.

Situated along Spain’s largest River, the Ebro, the 62-acre expo aims to inform people on global water issues and serve as a discussion forum for advocates and international policy makers. A goal of the expo is to produce a “Zaragoza Charter” which will detail recommendations to address such issues as access to clean water, water scarcity, water wars, and water conservation.

As the price of oil continues to climb, we are beginning to get a glimpse of what the post peak-oil world may  look like, and it’s not entirely pretty.

Protests in Europe have been widespread, as Europeans who already pay twice that of our US cousins for fuel begin to feel the financial consequences of consistent price increases.

Truck drivers in Spain and France have blockaded major roadways and paralysed traffic on major city arteries. Meanwhile in the UK, similar protests by truck drivers - who claim they are rapidly being forced out of business by high fuel prices - have taken place across the country.

Adding to the chaos, Shell tanker drivers chose the same weekend to strike over pay disputes, causing many petrol (gas) stations to run out of fuel. Government calls to avoid panic buying have predictably caused a peak-oil dress rehearsal, with long queues forming on many petrol station forecourts.

Solar thermal energy plants focus the glare of the Sun’s rays on a central location to create heat, which is then turned into electricity. Various methods exist to concentrate the solar radiation, including parabolic troughs, power towers with mirrors that track the Sun (heliostats), parabolic dishes, and Fresnel reflectors. See a history of solar thermal energy.

In case you missed them the first time around, here are the top 10 international environmental headlines that made news in the blogosphere for the week of March 31 - April 6.

1. Asia — United Nations Climate Change Talks: “Kyoto II” climate talks open in Bangkok

“The first formal talks in the long process of drawing up a replacement for the Kyoto climate change pact opened in Thailand on Monday with appeals to a common human purpose to defeat global warming.

‘The world is waiting for a solution that is long-term and economically viable,’ U.N. Secretary-General Ban Ki Moon said in a video address to the 1,000 delegates from 190 nations gathered in Bangkok.

International demand for solar energy has been steadily growing by 20-25% a year for the past two decades. In the United states, solar energy growth is about 60% a year. Looking at how fast solar energy plants are growing and how large they’re becoming year by year is reveals that the future for solar is shining bright.

World’s Largest Photovoltaic (PV) Solar Power Plants (Proposed and Operational)

By 2011, Deming, New Mexico, USA will be the home of the world’s largest solar power plant. This 300 Megawatt solar facility will be 15 times the size of the current largest solar plant on the planet. New Solar Ventures and Solar Torx are the companies behind the project. The solar energy plant will cover as many as 1,300 hectares and employ between 300 and 400 people. The project’s planners estimate that the plant will supply enough energy to power 240,000 homes.

The Solana solar plant, 70 miles from Pheonix, near Gila Bend, Arizona, USA, will compliment the Deming plant when both begin operations in 2011. It will produce 280 megawatts of energy, provide 1,500 jobs, and cover an area of 769 hectares. The solar power facility will be the child of Abengoa Solar and Arizona Public Service Company. However, the project depends on the United States Congress to renew clean energy tax credits, which would otherwise expire at the end of 2008. (Photo: APS. Source: Newlaunches via EcoFuss.)

What makes the energy consumption survey at Bosquevirtual.com unique–if you can get past the Forest Gump theme song in the site’s video promo–is the ambitious, tech-heavy cyber-activism sponsored by the survey’s Spanish creators, Union Fenosa.

For each person who takes the survey, Union Fenosa donates 1 Euro to Acciónatura, a Spanish organization that uses the money to reforest the Atlantic Forest in Brazil.

Bosquevirtual, or “Virtual Forest,” has also teamed up with Second Life, a 3D web Mecca for internet socializing. Along with the actual donation to reforestation, then, every two surveys completed generates the planting of a virtual tree in a virtual forest in the Second Life 3D world.
