How to make your daily commute bearable, if not downright pleasant. Solar Impulse craft inspires solar train for Indian Railways. India may soon be able showcase to the world a solar train, which uses a mix of thermal power and solar energy generated from panels on its roof. Science and technology minister Harsh Vardhan said he was inspired by Switzerland’s Solar Impulse project. “I got the inspiration when the Solar Impulse, the Swiss long range experimental solar powered aircraft landed in India,” he said. The minister described the project as the government’s bid to have a moving solar power plant. “We are looking into the project plan and once the demos are done we will collaborate with other concerned ministries,” he said.

To start with, the government will do a pilot on a goods train and if successful it will be replicated to other trains. The train will meet 15% of the energy requirement when on the move from the solar energy. When the solar radiation falls on a solar cell, direct current is generated which gets converted into an alternating current with a high efficient inverter.

French supermarkets will be banned from throwing away or destroying unsold food and must instead donate it to charities or for animal feed, under a law set to crack down on food waste. The French national assembly voted unanimously to pass the legislation as France battles an epidemic of wasted food that has highlighted the divide between giant food firms and people who are struggling to eat. As MPs united in a rare cross-party consensus, the centre-right deputy Yves Jégo told parliament: “There’s an absolute urgency – charities are desperate for food. The most moving part of this law is that it opens us up to others who are suffering.” Supermarkets will be barred from deliberately spoiling unsold food so it cannot be eaten.

“It’s scandalous to see bleach being poured into supermarket dustbins along with edible foods,” said the Socialist deputy Guillaume Garot, a former food minister who proposed the bill. How Amsterdam became the bicycle capital of the world | Cities. Anyone who has ever tried to make their way through the centre of Amsterdam in a car knows it: the city is owned by cyclists. They hurry in swarms through the streets, unbothered by traffic rules, taking precedence whenever they want, rendering motorists powerless by their sheer numbers. Cyclists rule in Amsterdam and great pains have been taken to accommodate them: the city is equipped with an elaborate network of cycle-paths and lanes, so safe and comfortable that even toddlers and elderly people use bikes as the easiest mode of transport.

It’s not only Amsterdam which boasts a network of cycle-paths, of course; you’ll find them in all Dutch cities. The Dutch take this for granted; they even tend to believe these cycle-paths have existed since the beginning of time. But that is certainly not the case. There was a time, in the 1950s and 60s, when cyclists were under severe threat of being expelled from Dutch cities by the growing number of cars. All that growing traffic took its toll. Depuis un peu plus de 2 ans et 60 articles que le présent blog de l’association L’Etang Nouveau existe, le GIPREB a rarement été le sujet de nos articles. Petit rattrapage et démontage en règle de l’éternel projet de dérivation des eaux EDF à travers la Crau que cet organisme ne cesse de présenter comme unique solution pour « sauver » l’étang de Berre… La raison du présent article est la publication par le GIPREB du n°5 de « Visions d’étang » daté de mai 2013.

Ce numéro a été émis à l’occasion de la signature du contrat d’étang. Nous en reproduisons ci-dessous la couverture, l’éditorial (lire surtout le 4ème paragraphe) et la page 14, première page d’un long délire de 8 pages sur l' »étude socioéconomique » justifiant la dérivation. Nous ne reproduisons pas entièrement ce document (il ne le mérite pas), mais ce monument de n’importe quoi méritait une réponse.

Le GIPREB et L’Etang Nouveau: Pour ceux qui ne le sauraient pas, un précédent article traite de nos rapports. Non, évidemment! Dear Bill Gates: 'Will you lead the fight against climate change?' | Environment. In 2009, nearly half of the world’s new polio cases were in India. The disease which can cause paralysis and death is highly infectious, but by January last year, thanks to a concerted vaccination programme, the country had gone three years without a single case of the virus.

It was officially “polio-free”. This immense achievement involved many people, including 2 million vaccinators fanning out across the vast country, but was due in no small part to the determination of the Bill and Melinda Gates Foundation, whose resources helped make those vaccinations possible. Gates himself is now betting on eradicating polio entirely from the world by 2018 – and who would bet against him? The polio story is one of countless other seemingly intractable global problems that the Gates Foundation has set its collective mind and resources to solving – HIV, malaria, sanitation, education, agriculture.

We agree. That’s where this video comes in. Will you lead us Bill? Keep it in the ground: Guardian climate change campaign | Environment. Tidal energy: Swansea project 'could lead to 70,000 jobs' | Business. The company behind the world’s first tidal energy scheme at Swansea Bay in south Wales hopes to create 70,000 jobs in the construction phase alone, if it can roll the programme out to five other, larger schemes at a total cost of £30bn. Tidal Lagoon Power, which received the green light in the budget to start talks with the government on subsidies, wants the £1bn Swansea project to be the start of a “game-changing” industry. The company is looking at sites for a factory to assemble wave turbines in the wider Swansea area, while a tender for generators has already been awarded to General Electric in Rugby, Warwickshire.

George Osborne announced a formal undertaking to open talks with Tidal Lagoon Power in his budget speech. The first project at Swansea Bay will generate 500 gigawatt-hours of electricity a year – enough for light and power for 120,000 homes – with turbines working 14 hours a day. Rooftops on new buildings built in commercial zones in France must either be partially covered in plants or solar panels, under a law approved on Thursday.

Green roofs have an isolating effect, helping reduce the amount of energy needed to heat a building in winter and cool it in summer. They also retain rainwater, thus helping reduce problems with runoff, while favouring biodiversity and giving birds a place to nest in the urban jungle, ecologists say. The law approved by parliament was more limited in scope than initial calls by French environmental activists to make green roofs that cover the entire surface mandatory on all new buildings. The Socialist government convinced activists to limit the scope of the law to commercial buildings. The law was also made less onerous for businesses by requiring only part of the roof to be covered with plants, and giving them the choice of installing solar panels to generate electricity instead.
