La esterilización de agua es un trabajo arduo. 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.

Pump water from your well, or shallow surface source directly with Solar PV panels. Size your solar water pumping system with this step-by-step guide to defining, and building your solar water pumping project. Solar water pumping systems include solar PV panels, a controller, and the pump itself. The examples included in this audiobook match the model pump, with the solar power supply required to produce a given average water production per day.

A behind-the-scenes look at the robustly competitive race to dominate the market for electric cars, the larger-than-life moguls behind them, and the changes that are transforming the auto industry. In the 1980s, it was unimaginable that the home computer would become as common and easy to use as a toaster. Today, plug-in charging stations and smart grids seem like something still far off in the future. But by 2020, the auto industry will look very different from today's field of troubled auto giants.

In her best-selling books Blue Gold and Blue Covenant, world-renowned water activist Maude Barlow exposed the battle for ownership of our dwindling water supply and the emergence of an international, grassroots-led movement to reclaim water as a public good. Since then, the United Nations has recognized access to water as a basic human right - but there is still much work to be done to stem this growing crisis.

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.

In the middle of the Mojave Desert, Las Vegas casinos use billions of gallons of water for fountains, pirate lagoons, wave machines, and indoor canals. Meanwhile, the town of Orme, Tennessee, must truck in water from Alabama because it has literally run out.Robert Glennon captures the irony - and tragedy - of America’s water crisis in a book that is both frightening and wickedly comical.

Each day, headlines warn that baby bottles are leaching dangerous chemicals, nonstick pans are causing infertility, and plastic containers are making us fat. What if green chemistry could change all that? What if rather than toxics, our economy ran on harmless, environmentally-friendly materials? Elizabeth Grossman, an acclaimed journalist who brought national attention to the contaminants hidden in computers and other high tech electronics, now tackles the hazards of ordinary consumer products.

Deforestation. Desertification. Species extinction. Global warming. Growing threats to food and water. The driving issues of our times are the result of one huge problem: Us. As the population continues to grow, our problems will increase. And this means that every way we look at it, a planet of 10 billion people is likely to be a nightmare. Stephen Emmott, a scientist whose lab is at the forefront of research into complex natural systems, sounds the alarm. This is a snapshot of our planet, and our species, approaching a crisis, and a stark analysis of where this leaves us.

The sixth "mass extinction event" in the history of planet Earth is currently under way, with over two hundred species dying off every day. The cause of this seismic event is also the source of the single biggest threat to human life: our own inventions. But for all our talk about sea levels and biotechnology, do we really know what our future will actually look like? Will our immune systems be attacked by so-called super bugs, always evolving, and more easily spread than ever? Will the disappearance of numerous species cripple the biosphere?

A poet at heart, Amy Minato rejects her life of consumption in Chicago to go back to nature - specifically, to a commune in Oregon, where she rediscovers herself. She also cops occasionally to the pretentiousness of her mission, and laughs along with the listener at her attempts to be both environmentally friendly and sane, considering the fact that she’s moved in with a bunch of strangers in a remote locale.

Kristen Iversen grew up in a small Colorado town close to Rocky Flats, a secret nuclear weapons plant once designated "the most contaminated site in America." Full Body Burden is the story of a childhood and adolescence in the shadow of the Cold War, in a landscape at once startlingly beautiful and--unknown to those who lived there--tainted with invisible yet deadly particles of plutonium.

Economists insist that recovery is at hand, yet unemployment remains high, real estate values continue to sink, and governments stagger under record deficits. The End of Growth proposes a startling diagnosis: humanity has reached a fundamental turning point in its economic history. The expansionary trajectory of industrial civilization is colliding with non-negotiable natural limits.

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.
