Selah: Water from Stone. A fleet of trucks just drove themselves across Europe. "Light recycling" tech could save incandescent bulbs from obsolescence. Incandescent light bulbs may put out a warmer-looking, more familiar type of light than LEDs or compact fluorescents, but they're far less efficient – the majority of the energy they use is wasted, mainly in the form of heat.

"Light recycling" tech could save incandescent bulbs from obsolescence

Technology may save them yet, however. Scientists at MIT and Purdue University have developed an ultra-efficient new incandescent bulb that reuses the heat it gives off, converting that heat into more light. With traditional incandescent bulbs, both visible and infrared light are created by heating a tungsten filament, causing it to glow. Both wavelengths flow unimpeded out into the room, with the infrared doing nothing other than dissipating as heat. NASA's Game-Changing Plan To Save Coral Reefs. Cheap, waterless toilet that turns waste into clean water and power to be trialed in Africa. A cheap, easy to maintain, "green" toilet that uses no water and turns human waste into electricity and clean water will be trialed in 2016, possibly in Ghana.

Dubbed the "Nano Membrane Toilet" by its creators from Cranfield University, UK, this new approach to managing waste could help some of the world's 2.3 billion people who have no access to safe, hygienic toilets. How Dow Chemical Is Turning Sewage Into a Refreshing Drink. “This is step one of the filtration process,” says Snehal Desai, struggling to suppress his gag reflex.

Conceived as a cheap, efficient, modular system that can be scaled up to produce thousands of liters per day, Water Works is installed with no upfront costs and requires minimal maintenance or training to operate. Water conservation has costly — and stinky — downsides. Under orders to slash water use amid a historic drought, cities and towns across the state saved about 75 billion gallons in July, eclipsing Gov.

E-waste: What we throw away doesn't go away. In the life of almost every household appliance, there comes that moment of out with the old and in with the new.However, while electrical and electronic equipment have never been more efficient, economical or in demand, consumers’ desire to own the best and the latest is contributing to an environmental issue of increasing seriousness and concern.

E-waste: What we throw away doesn't go away

“E-waste is one of the fastest growing waste streams in developing, emerging and developed regions and it covers all electrical and electronic equipment and parts discarded by consumers,” says Dr Sunil Herat, Associate Editor of the journal Waste Management & Researchand a Senior Lecturer in the School of Engineering at Griffith University in Queensland, Australia. “According to figures published in the Global E-waste Monitor 2014 and compiled by the United Nations University, last year an estimated 41.8 million metric tonnes of e-waste was discarded throughout the world.

The Electronic Afterlife. Air2Nitrous International: HOME. Air2Nitrous device claimed to cut vehicle exhaust emissions by 90 percent. Driving an electric car that gives off no emissions is one of the best ways to reduce your personal transport carbon footprint.

Air2Nitrous device claimed to cut vehicle exhaust emissions by 90 percent

But if an EV is out of reach, the next best thing could be a simple retrofittable, scalable device called Air2Nitrous (A2N). Its creators claim it can reduce engine emissions by 90 percent, while cutting fuel consumption by 20 percent. The Air2Nitrous team describes its electronic emissions control system as a "first phase" device because it works before and during combustion. It cuts emissions by increasing the amount of oxygen molecules and decreasing the amount of nitrogen molecules in the combustion chamber. As air from the atmosphere passes through the vehicle’s air filter, it then passes unobstructed through the converter ring located in the air intake duct.

According to the company, less nitrogen means less nitric oxide and nitrogen oxide (NOx), and a decrease by up to 90 percent a range of harmful gases, including CO2. Source: Air2Nitrous. Shoe That Grows gives poor kids footwear that fits for years. For children living in poverty, footwear is one of many problems. Almost as soon as a child has received shoes to wear, they're likely to have grown out of them and have to make do with them being too small. The Shoe That Grows changes this. It allows children to adjust its size as their feet grow. View all.

California’s Epic Drought: One Year of Water Left. Wars over California’s limited water supply have been going on for at least a century. Water wars have been the subject of some vintage movies, including the 1958 hit The Big Country starring Gregory Peck, Clint Eastwood’s 1985 Pale Rider, 1995’s Waterworld with Kevin Costner, and the 2005 film Batman Begins.

Most acclaimed was the 1975 Academy Award winner Chinatown with Jack Nicholson and Faye Dunaway, involving a plot between a corrupt Los Angeles politician and land speculators to fabricate the 1937 drought in order to force farmers to sell their land at low prices. The plot was rooted in historical fact, reflecting battles between Owens Valley farmers and Los Angeles urbanites over water rights. Today the water wars continue, on a larger scale with new players.
