This technology seems to me to be much more beneficial on a local scale, what if every home had its own battery, then home power generation becomes economically more viable for everyone. If you could show that a system like this could pay for itself in say 5 years then every home would want one. Plus for this to be implemented on a large scale requires massive investment that could be decades away. Share the technology and lets get it in homes by next year. Great ted talk. Jon Senior 0 Reply 1 hour ago: I agree 100%. Localised energy production would also make energy consumers more conscious of their consumption and encourage efforts to reduce it. We can invent and invent all we want, but the fast solution to allowing renewable energies to take centre stage is to reduce the base energy draw. With lower baseline consumption, smaller "always on" generators are required to keep the grid operational. Town and house-l

"Water is necessary for many applications apart from sustaining life. Because it may not be available in sufficient quantity or at the quality required, some form of treatment may be necessary to meet the needs of an application. More stringent water quality specifications normally require more elaborate treatment methods. Challenges of availing clean water suitable for specific applications have led to innovations in water production to meet the needs of each sector. This research service reports on innovations in water production that specifically impact each key sector. It gives the industry snapshot of each key sector, its current water scenario, innovation landscape, global trends and technology roadmap till 2025. Several examples of innovative non-technological ways to produce or provide water are presented at the end of the report. Some key patents and contact details of key industry players are also given."

"Water is fundamental to human life and survival-our most fundamental instinct. Because of the forecasted challenges around sourcing adequate quantities of quality water, some feel future wars will be fought over water and not oil. Other challenges are related to the increasing population concentrations and climate-related weather events. This article considers water-related challenges arising out of urbanization and looks at how policies and technology can help make transition to more sustainable use of water work. "

A new era for commodities Cheap resources underpinned economic growth for much of the 20th century. The 21st will be different. NOVEMBER 2011 * Richard Dobbs, Jeremy Oppenheim, and Fraser Thompson Source: McKinsey Global Institute, Sustainability & Resource Productivity Practice In This Article Exhibit: In little more than a decade, soaring commodity prices have erased a century of steady declines. About the authors Comments (2) Has the global economy entered an era of persistently high, volatile commodity prices? Our research shows that during the past eight years alone, they have undone the decline of the previous century, rising to levels not seen since the early 1900s (exhibit). In addition, volatility is now greater than at any time since the oil-shocked 1970s because commodity prices increasingly move in lockstep. Our analysis suggests that they will remain high and volatile for at least the next 20 years if current trends hold-barring a major macroeconomic shock-as global resource markets oscillate in response to surging global demand and inelastic supplies. Back to top Demand for energy, food, metals, and water should rise inexorably as three billion new middle-class consumers emerge in the next two decades.1 The global car fleet, for example, is expected almost to double, to 1.7 billion, by 2030. In India, we expect calorie intake per person to rise by 20 percent during that period, while per capita meat consumption in China could increase by 60 percent, to 80 kilograms (176 pounds) a year. Demand for urban infrastructure also will soar. China, for example, could annually add floor space totaling 2.5 times the entire residential and commercial square footage of the city of Chicago, while India could add floor space equal to another Chicago every year. Such dramatic growth in demand for commodities actually isn't unusual. Similar factors were at play throughout the 20th century as the planet's population tripled and demand for various resource

I recently noted that Hawaii has enacted a law that requires all new homes to install solar water heaters. Eventually, Hawaii may have as many water heaters as Israel, where 90% of homes have solar water heaters installed. When viewed from above, the Jerusalem often glitters with the shine of the thousands of solar heaters that adorn rooftops.

this new so-called Klimatic Base 1 AirWater Machine does its share of inventive (but not entirely unique) water purifying nonetheless, with it promising to pull drinkable water out of the air. That's done, as you might have guessed, with the aid of an apparently standard dehumidifier, which gets paired with several filters and a UV light chamber that the company says will eliminate any bacterial content that might be in the water.

"With almost 2 billion of Earth's 7 billion people lacking access to clean drinking water, about 14 percent of the population still defecating outdoors and a child dying every 20 seconds due to poor sanitation, water was also eighth on the likelihood list."

Hawaii has become the first state to require solar water heaters in new homes. The bill was signed into law by Governor Linda Lingle, a Republican. It requires the energy-saving systems in homes starting in 2010. It prohibits issuing building permits for single-family homes that do not have solar water heaters. Hawaii relies on imported fossil fuels more than any other state, with about 90 percent of its energy sources coming from foreign countries, according to state data.

"distributing water treatment"

""The water footprint, like the carbon footprint, will become an increasingly critical factor to consider in addressing reliable and sustainable energy development worldwide.""

"Many drinking water treatment facilities worldwide disinfect water with ultraviolet light because it's quick and efficient, kills protozoa such as Giardia, and doesn't introduce potentially harmful disinfection by-products. But a new study ("UV Disinfection Induces a Vbnc State in Escherichia coli and Pseudomonas aeruginosa") shows that UV treatment alone can push bacteria into a dormant state instead of killing them, and that in some cases, the bacteria can later revive and proliferate. "

SANTIAGO, Chile - BHP Billiton is seeking approval to build a $3.5 billion US water desalinization plant to service its Escondida copper mine in northern Chile, one of the world's top sources of the metal, a company spokesman said Saturday.
