Dousing Flames with Low-Frequency Sound Waves

A new type of extinguisher that uses sound waves to put out fires has been built by two engineering students in the US. Both chemical- and water-free, the invention offers a relatively non-destructive method of fire control, which could find applications in fighting small fires in the home, and the researchers now hold a preliminary patent application for their device.

While the concept of using sound waves to extinguish flames is not new, previous attempts to realize the principle – including efforts by teams at West Georgia University and the US Defense Advanced Research Projects Agency (DARPA) – had not been successful.

Undeterred by this, as well as initial [...]

Drones could help save the world’s forests (Wired UK)

Lauren Fletcher is aiming to tackle global climate change by planting one billion trees per year with his fleet of drones.BioCarbon EngineeringMatthew Ritchie Fletcher, who is the CEO of Oxford-based BioCarbon Engineering, and his team are developing planting technologies that will be integrated with unmanned aerial vehicles (UAVs) and sensors, allowing them to carry out "precision forestry". This uses geospatial information in forest planning and management, as well as site-specific silvicultural operations.The technology has reached the semi-final stage of the UAE's Drones for Good competition taking place in Dubai.

Dutch Entrepreneur Says He Can Clean Up the Great Pacific Ocean Garbage Patch

This summer, a small armada of vessels from all over the globe will converge in the Pacific Ocean. Their arrival is expected to herald what arguably can be called one of the more creative environmental cleanup projects. As many as fifty boats consisting of everything from research vessels to private cruisers, sailboats and commercial fishing vessels will track the Pacific’s Great Garbage Patch as it makes its rocky journey through currents between Hawaii and the California coastline.

The mega exploration, as the team at the nonprofit organization, The Ocean Cleanup, calls it, will help the organization close in on their efforts to clean up the [...]

Scientists Found a Way to Turn Deadly Female Mosquitoes into Harmless Males

A global team of scientists have found a way to turn female mosquito embryos into males at a genetic level, according to a paper published in Science Express. The finding could really come in handy, since females are the ones that bite, constantly hunting for blood to develop their eggs.

For some of us, mosquitoes are merely an annoyance we can solve with a simple swat or two. But in many parts of the world they carry deadly diseases and are major threat to the health of a population. There are about 200,000 cases of yellow fever each year. And of these, 30,000 result in death. There has been a number of efforts over the years to solve this problem, but the process usually [...]

Why Teenagers Are Suing States Over Climate Change

Oral arguments were heard on Tuesday in a long-running lawsuit brought by two teenagers against the state of Oregon. The teens are seeking to force the state to take more aggressive action on climate change and thereby better protect the planet for future generations.

The suit is one of dozens of legal actions and petitions filed in virtually every state, along with federal courts, as part of a campaign spearheaded by the Oregon-based nonprofit Our Children’s Trust. “Our purpose is to protect earth’s natural systems for current and future generations,” the organization declares on its Web site. “We are here to empower and support youth as they stand up for their lawful [...]

How One California Farmer is Battling the Worst Drought in 1,200 Years

On a warm March afternoon, farmer Cannon Michael walks alongside wheat fields adjacent to his house in Los Banos, in California’s Central Valley. Most of these fields won’t be watered again this year.“Wheat’s not a glamorous crop, but it makes a lot of bread,” Michael quips.This wheat, though, won’t return much money, Michael says. So it will be harvested for his sister’s two bakeries in San Francisco and the land fallowed, along with some fields formerly planted in alfalfa and cotton. They are among more than 1,000 acres Michael left unplanted this season to try and conserve water, amounting to about 10 percent of the 10,500 irrigated acres that make up his farm, Bowles Farming [...]

In Brazil, Water is Power

Of the many stories I heard about the drought while I was in Brazil earlier this month, one stands out: a colleague was riding the elevator in her building and saw a note from a concerned neighbor. “Dear neighbors,” the note read, “As you know we are in a severe crisis. Everyone must do their part to conserve water. That is why I have decided to only wash my car once per month. I hope everyone else can make a similar sacrifice.”I had just spent five days in Sao Paulo, visiting electric utility executives to imagine how software technology could better engage their consumers toward addressing the deepening crisis. Twenty million people live in Sao Paulo, which is suffering its worst [...]

Why the Production of Conservation Will Solve the Water Crisis

California is a year away from running out of water. Yet, my water bill is more or less the same as what I would have paid four years ago before the current drought began. Meanwhile, farmers along I-5 in the Central Valley have uprooted their orchards and fallowed their fields because water isn’t available for their crops. Water suffers from massive externalities that are not reflected in its price.The biggest mistake we’ve made in how we manage our water resources is placing responsibility for water conservation in the hands of the same agencies responsible for providing (i.e., selling) water. How do you tell your customers that you want them to use less of your product? If you’re [...]
