Los esterilizadores de agua energizados con electricidad solar FV son un medio efectivo para esterilizar agua desde fuentes locales polutas, aún agua salobre, con seguridad, fiable y sin costos de combustible. El agua encontrada en la naturaleza está llena de elementos patógenos que pueden causar infecciones y enfermedades. Los esterilizadores ultravioletas (UV) matan el 99.99% de todos los patógenos dañinos y aportan un agua potable y segura para beber.

Conventional wisdom has North America entering a new era of energy abundance thanks to shale gas. But has industry been honest? Cold, Hungry and in the Dark argues that declining productivity combined with increasing demand will trigger a crisis that will cause prices to skyrocket, damage the economy, and have a profound impact on the lives of nearly every North American.

Sterilizing water is a big job. Solar electric (PV) powered UV water sterilizers are an effective way to sterilize your water from local polluted sources, even brackish water, with safety, reliability, and no fuel-costs. Water found in nature is full of pathogens which can cause disease and illness. Ultra-violet (UV) sterilizers kill 99.99% of all dangerous pathogens and render your water potable and safe to drink.

In Anna Clark's full account of this American tragedy, The Poisoned City recounts the gripping story of Flint’s poisoned water through the people who caused it, suffered from it, and exposed it. It is a chronicle of one town, but could also be about any American city, all made precarious by the neglect of infrastructure and the erosion of democratic decision making. Places like Flint are set up to fail - and for the people who live and work in them, the consequences can be fatal.

As a changing climate threatens the whole country with deeper droughts and more furious floods that put ever more people and property at risk, Texas has become a bellwether state for water debates. Will there be enough water for everyone? Is there the will to take the steps necessary to defend ourselves against the sea? Is it in the nature of Americans to adapt to nature in flux?

In this fresh and powerful work of environmental history, Martin Doyle explores how rivers have often been the source of arguments at the heart of the American experiment - over federalism, taxation, regulation, conservation, and development. Doyle tells the epic story of America and its rivers, from the US Constitution's roots in interstate river navigation, the origins of the Army Corps of Engineers, the discovery of gold in 1848, and the construction of the Hoover Dam and the TVA during the New Deal, to the failure of the levees in Hurricane Katrina.

Plastic pollution is the environmental scourge of our age, but how can you make a difference? This accessible guide, written by the campaigner at the forefront of the antiplastic movement, will help you make the small changes that make a big difference, from buying a reusable coffee cup to running a cleanup at your local park or beach.

The water coming out of your tap is four billion years old and might have been slurped by a Tyrannosaurus Rex. We will always have exactly as much water on Earth as we have ever had. Water cannot be destroyed, and it can always be made clean enough for drinking again. In fact, water can be made so clean that it actually becomes toxic. As Charles Fishman brings vibrantly to life in this delightful narrative excursion, water runs our world in a host of awe-inspiring ways, which is both the promise and the peril of our unexplored connections to it.

Pollution is the single largest cause of death in the developing world. One in seven people in low- and middle-income countries die as a result of it. Simply put, pollution is now the world's most prevalent health risk. And yet, while most everyone has heard about "going green"; few are aware of the more dire and sinister brown pollution - places where man-made toxic pollutants have taken root and spread. Brown sites poison millions of people every year, causing needless suffering and death. After witnessing several brown sites firsthand and meeting families trapped by poverty in these toxic hot spots, environmentalist Richard Fuller founded the Blacksmith Institute, now renamed Pure Earth, a global nonprofit that initiates large-scale cleanups of some of the most polluted places on earth. 

On the morning of April 26, 1986, Europe witnessed the worst nuclear disaster in history: the explosion of a reactor at the Chernobyl Nuclear Power Plant in Soviet Ukraine. Dozens died of radiation poisoning, fallout contaminated half the continent, and thousands fell ill. In Chernobyl, Serhii Plokhy draws on new sources to tell the dramatic stories of the firefighters, scientists, and soldiers who heroically extinguished the nuclear inferno. He lays bare the flaws of the Soviet nuclear industry....

The story of the American West is the story of a relentless quest for a precious resource: water. It is a tale of rivers diverted and dammed, of political corruptions and intrigue, of billion-dollar battles over water rights, of ecologic and economic disaster. In Cadillac Desert, Marc Reisner writes of the earliest settlers, lured by the promise of paradise, and of the ruthless tactics employed by Los Angeles politicians and business interests to ensure the city's growth. He documents the bitter rivalry between two government giants to transform the West.

Bold is a radical, how-to guide for using exponential technologies, moonshot thinking, and crowd-powered tools to create extraordinary wealth while also positively impacting the lives of billions.

Strategically situated at the gateway to the Mississippi River yet standing atop a former swamp, New Orleans was from the first what geographer Peirce Lewis called an "impossible but inevitable city". How New Orleans came to be, taking shape between the mutual and often contradictory forces of nature and urban development, is the subject of An Unnatural Metropolis.

Più volte, negli ultimi decenni, l'Italia è diventata protagonista in negativo delle prime pagine dei giornali, nazionali e internazionali, a causa della cosiddetta "emergenza rifiuti". Le città d'arte del Belpaese sommerse dai rifiuti sono un'immagine che purtroppo ricorre periodicamente, suscitando l'interesse momentaneo della classe politica di turno per poi ritornare nell'oblio senza che sia stata trovata una soluzione definitiva.

Die Energiewende steckt in einer tiefen Krise: Regierungspolitiker räumen mittlerweile ein, dass kaum etwas in dem deutschen Musterschülerprojekt nach Plan läuft. Millionen Stromkunden bringen mehr als 20 Milliarden Euro an jährlichen Subventionen auf, während nur wenige profitieren. Das grüne Jobwunder fand nur in Prognosen statt. Und zur Kohlendioxid-Reduzierung trägt die Ökoenergie nichts bei.

Barcellona, Manchester o Salonicco, Torino, Bari o Genova: cosa hanno in comune queste città? Il fatto che possono essere considerate smart, misurandole con diversi parametri che vanno dai trasporti all'istruzione, dalla sanità alla sostenibilità ambientale all'innovazione tecnologica. Smart city è dunque una definizione complessa cha allude ad una trasformazione delle nostre attuali città con l'obiettivo non solo del superamento delle emergenze energetiche ed ambientali, ma anche della qualità del vivere per il cittadino e per la comunità, sul piano sociale ed economico.

What should I wear? More than ever, we are told it should be something new. Today, the clothing industry churns out 80 billion garments a year and employs every sixth person on Earth. Historically, the apparel trade has exploited labour, the environment and intellectual property. Best-selling journalist Dana Thomas has travelled the globe to discover the visionary designers and companies who are reclaiming traditional craft and launching cutting-edge sustainable technologies to produce better fashion.

We prefer not to talk about it, but we should. Disease spread by waste kills more people worldwide every year than any other single cause of death. Even in America, nearly two million people have no access to an indoor toilet. Yet the subject remains unmentionable. Moving from the underground sewers of Paris, London, and New York (an infrastructure disaster waiting to happen) to an Indian slum where ten toilets are shared by 60,000 people, The Big Necessity breaks the silence, revealing everything that matters about how people do - and don't - deal with their own waste.

In Secondhand, Adam Minter delves into the vast, multibillion-dollar industry that resells used stuff around the world. He follows the trail of unwanted objects from the closets, garages, and storage units of Middle America to epic used-goods markets in Canada, Mexico, Japan, Ghana, India, Malaysia, and beyond. Secondhand takes us through the often painful and heartbreaking process of cleaning out a lifetime’s worth of possessions and shows that used stuff still has a place in a world that values the new and shiny.
