Comments Off on Stanford sodium-based battery could be more cost-effective than lithium

The quest for the best battery is of vital importance as the world transitions to renewable energy . Now a Stanford University -led team has designed what they think might offer a cheaper alternative to lithium – a sodium -based battery. While it’s not the world’s first sodium ion battery, the Stanford design costs 80 percent less than a lithium-ion battery , and it is capable of storing the same amount of energy . Lithium-ion batteries may currently reign supreme, but according to Stanford, sodium-ion batteries could compete in terms of cost-per-storage. They said lithium costs around $15,000 per ton to mine and refine, while the “widely available sodium-based electrode material” they utilized in their new battery costs a fraction of that at $150 per ton. It’s a significant difference as materials comprise around one quarter of the price of a battery. Related: Researchers successfully made a battery out of trash Stanford chemical engineer Zhenan Bao said in a statement, “Nothing may ever surpass lithium ion in performance. But lithium is so rare and costly that we need to develop high-performance but low-cost batteries based on abundant elements like sodium.” The sodium-based electrode is made up of a positively charged ion, sodium, and a negatively charged ion, myo-inositol. You may not be familiar with myo-inositol, but Stanford says it’s in baby formula, and derives from rice bran “or from a liquid byproduct of the process used to mill corn.” Like sodium, it too is naturally abundant. While the researchers think they have shown sodium-based batteries can be cost effective compared to lithium ion batteries, they aim to keep working on the design . They’ve optimized the charging cycle and cathode, according to Stanford, but engineer Yi Cui says optimizing the phosphorous anode could improve the battery. The journal Nature Energy recently published the study online . Stanford University engineers collaborated on the project with a researcher from the SLAC National Accelerator Laboratory .

Dead Sea salt reveals drought on a scale never recorded – and it could happen again

Comments Off on Dead Sea salt reveals drought on a scale never recorded – and it could happen again

Thick layers of Dead Sea salt found 1,000 feet below the sea bed holds clues to our planet’s past – and a warning. The salt reveals during warm periods in Earth’s history, the region – the Dead Sea is bordered by Palestine, Jordan, and Israel – suffered from drought with no known precedent. The salt, scrutinized by an international team of researchers led by Yael Kiro of Columbia University , doesn’t just offer a history lesson, but a caution climate change could seriously dry the region again in the future. Crystalline salt from beneath the Dead Sea reveals 120,000 and 10,000 years ago, rainfall in the area was a fifth of modern levels. These dry periods were naturally caused. But human-caused climate change today could potentially dry the region – which is already struggling – more than we realized. Right now the Middle East’s fresh water per capita availability is 10 times less than the world average, according to the United Nations Food and Agriculture Organization. Related: Dramatic Video Captures Rebirth of the River Zin in Israel’s Negev Desert Back in 2010, scientists drilled 1,500 feet into the Dead Sea bed’s deepest part. They obtained a cross-section that provided 200,000 years of climate history in the area. Alternating layers of salt and mud showed dry and wet times. Only recently, however, did scientists analyze the core in great detail. The region suffered from what Columbia University called epic dry periods. Kiro said in a statement, “All the observations show this region is one of those most affected by modern climate change, and it’s predicted to get dryer. What we showed is that even under natural conditions, it can become much drier than predicted by any of our models.” The journal Earth and Planetary Science Letters published the research in an early online edition . Six other scientists from institutions in Israel and Spain also contributed to the study. Via The Guardian and Columbia University Images via Wikimedia Commons ( 1 , 2 )

Michigan to replace thousands of Flint water lines in settlement

Comments Off on Michigan to replace thousands of Flint water lines in settlement

A judge approved a settlement with the state of Michigan today that will come as welcome news to thousands of residents: at least 18,000 homes in Flint will have their toxic water pipes replaced over the next three years. The state has committed $87 million to identify and replace any service lines containing lead or galvanized steel by 2020. The settlement marks the end of a lawsuit filed last year by Concerned Pastors for Social Action , the Natural Resources Defense Council , the American Civil Liberties Union and a resident of Flint, targeted at both city and state officials. Flint Mayor Karen Weaver has praised the agreement. The $87 million used to replace the pipes will come from a variety of sources. The Water Infrastructure Improvements for the Nation (WIIN) Act, which was passed by Congress last year, will provide up to $20 million in funds, with the state matching another $20 million. The state must also hold an extra $10 million in reserve, in case the repairs end up being more expensive than anticipated. The state will also cover the $895,000 the plaintiffs ran up in litigation costs. Related: 1,700 Flint residents sue the EPA over tainted water In the meantime , residents will have to either pick up bottled water from designated locations in the city, or they’ll have to install water filters on their taps. Though the filters have been shown to render the city’s water safe for human consumption, many residents are nervous and distrustful of anything that comes out of their taps (and with good reason). The lawsuit had asked that bottled water be delivered door to door throughout the city until pipe replacement was complete, but the judge shot down that request.

Comments Off on MIT develops new technology that shocks the salt out of water

The bright minds at MIT have developed a way to separate salt from water that is easy, cheap, and effective. Using an electrical current, the team discovered how to quite literally shock the salt out of water, a technique designed to aid disaster-stricken areas needing fresh drinking water. This process is said to be affordable and avoids some of the snags associated with other desalination methods, such as filters getting clogged and boiling water requiring too much energy.

Texas A&M students design much-needed new hospital for Roatán Island, Honduras

Comments Off on Texas A&M students design much-needed new hospital for Roatán Island, Honduras

Roatán Island lies around 35 miles off the coast of Honduras , and is home to a population of some 100,000 people—yet its outdated hospital has only 38 beds. According to Dr. Raymond Cherrington, a family physician at the hospital, this means that there are sometimes three patients in a single bed, creating a situation that is not only uncomfortable but hazardous as close proximity heightens the risk of infection. But, with support from non-profit Global Healing and architecture firm HKS , 27 environmental design students at Texas A&M have created seven proposals for a new, larger facility that is designed to suit the needs of doctors and patients alike, while addressing the particular needs of the Honduran climate.

Comments Off on Snow-Melting Road Salt Wrecks Havoc on the Environment, Infrastructure

Road salt photo from Shutterstock It’s been a particularly harsh winter for the Eastern United States, and many local governments have exhausted their stockpiles of salt used to melt ice on roads and sidewalks. Salt makes streets safer to navigate when conditions are treacherous, however there are big drawbacks when it comes to infrastructure and the environment. According to a report on Treehugger , salt adversely impacts wildlife, plants, water and soil when it inevitably finds its way into the groundwater, rivers and streams. Road salt can also contain chemicals like sodium ferrocyanide and ferric ferrocyanide , it’s corrosive, and it speeds up the deterioration of infrastructure – every dollar spent on salt costs an estimated four dollars in repairs to roads and bridges.
