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 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. "

"Conflict mining remains an important issue, and one we are beginning to see governments step in to address in different ways. With the global economy as interconnected as ever, it's important to note that many of the products and technologies we use in our daily lives begin at the same source: mines. With leading companies across industries such as electronics, retail and jewelry, auto manufacturing, lighting aerospace, construction, and other industries relying on these commonly used 3TG metals - tin, tungsten, tantalum and gold - implementing effective regulation is essential in order to further advance support to eliminate or reduce human rights violation."

A strike planned to start on Monday at Southern Copper's Peruvian mine Cuajone has been temporarily suspended pending mediation, officials from the company and union said. Southern, one of the world's largest copper producers, has been hit by strikes this year in Peru as workers demand a larger slice of the country's economic boom. Union leaders had planned to go on strike again because the company had threatened to fire about a dozen workers for participating in recent walkouts. But Roman More, head of the union at Cuajone, said the strike slated for Monday was called off as the company agreed to sit down with workers and the government for talks on Tuesday. Unions from the company's Ilo smelter and Toquepala mine were also expected to participate. "We are going to meet on Tuesday to see if we can reach an agreement about the firings. The meetings were requested by the government," More said. Alberto Giles, the company's human resources director, said the strike plans were scrapped. "In the case of Cuajone ... they suspended the strike plan," he said. "With regards to Ilo, the strike was supposed to start on Wednesday, but I don't think there will be a strike. I think the strike will also be canceled at Ilo." Cuajone, which produced some 148,939 tonnes of copper last year, is Southern's biggest mine in Peru, the world's No. 2 copper producer.

The robots are being developed for nursery schools and researchers in California reported last year that toddlers even regard the more sophisticated artificial friends as human.

In keeping with the amount of virtual ink this item deserves, we're going to try and keep this short. The Oregon Institute of Science and Medicine held a press conference this morning to announce that 31,000 "scientists" have signed a petition rejecting claims of human-caused global warming.

That may be a little aggressive, but Princeton University engineers have developed a device that may change the way that we power many of our smaller gadgets and devices. By using out natural body movement, they have created a small chip that will actually capture and harness that natural energy to create enough energy to power up things such as a cell phone, pacemaker and many other small devices that are electronic.

There is a school of thought that climate is at the center of 'everything'. If we solve climate, we'll solve many other issues: not only health, but also growth, education, food, water, security, migration, ... Major thinkers such as Latour, Sloterdijk or Beck have written about this.

It seems that in the last decade scientists have switched goals from producing efficient LEDs to producing "natural light" LEDs. However, whenever this was achieved, significant efficiency sacrifices were made to enable experimentation to work. Through use of a nano-crystaline coating, it seems that scientists at Bilkent University, Turkey have succeeded in creating an LED that "produces attractive white light while wasting next-to-no electricity". The definition of attractive is that for each watt of light produced, around 300 lumens are visible to the human eye. This compares with fluorescents which produce around 80 lumens per watt, according to the article. There is however a barrier to market. This is because the nano-crystalline coating is expensive and apparently difficult to produce.
