According to the U.N. Refugee Agency, over 30,000 people are forced to flee their homes every day. A new feature from NPR highlights one professor from Leipzig University that decided to take action on the refugee crisis, addressing the around 6,000 refugees living in her city.

Carmen Bachmann believed that as a professor, it was her duty to ease this problem, and she sought out to do so by providing advanced academic training to those in refugee camps. Listen to the full story above.

In an effort to develop an eco-friendly battery, researchers from Ulsan National Institute of Science and Technology (UNIST) have created a battery that can store and produce electricity by using seawater.

The research is expected to dramatically improve cost and stability issues over the next five years, with researchers confident about commercialization.

The driving force behind the battery is the sodium found in seawater. Because sodium is so abundant, the researchers believe that this new system will be an attractive supplement to existing battery technologies. Because the seawater battery is cheaper and more environmentally friendly than lithium-ion batteries, the team says the seawater battery could provide an alternative option in large-scale energy storage.

This from UNIST:

Seawater batteries are similar to their lithium-ion cousins since they store energy in the same way. The battery extracts sodium ions from the seawater when it is charged with electrical energy and stores them within the cathode compartment. Upon electrochemical discharge, sodium is released from the anode and reacts with water and oxygen from the seawater cathode to form sodium hydroxide. This process provide energy to power, for instance, an electric vehicle.

The estimated total number of bacteria of the planet is estimated at five nonillion, and the world of bacteria is stocked with potential, including electrical production.

Researchers from the University of California are looking to tap into some of that potential by looking at “electrogenic” bacteria, which generate current as part of their metabolism. The research team has found a new way to mimic that ability upon non-electrogenic bacteria, opening up opportunities for new developments in sustainable electricity generation and wastewater treatment.

“The concept here is that if we just close the lid of the wastewater treatment tank and then give the bacteria an electrode, they can produce electricity while cleaning the water,” says Zach Rengert, co-first author of the study. “And the amount of electricity they produce will never power anything very big, but it can offset the cost of cleaning water.”

Bill Nye the Science Guy first debuted in 1993, bringing an entertaining and educational program to public television. After 100 episodes, the show went off air in 1998, but Nye has continued to hold a prominent place in mainstream scientific dialogue.

Now, Nye is going back to his roots with Bill Nye Saves the World, set to air on Netflix on April 21.

A new study published in the Proceedings of the National Academy of Sciences predicts that as climate change continues to accelerate average temperatures, electrical grids may be unable to meet peak energy needs by the end of the century.

The electrical grid is the central component of energy distribution and consumption. In order to upgrade this massive infrastructure to meet increasing demands, the researchers behind the study estimate nearly $180 billion would have to be invested in the U.S. grid.

This from the study:

As the electricity grid is built to endure maximum load, our findings have significant implications for the construction of costly peak generating capacity.

Read the full paper.

On top of acknowledging the correlation between increasingly hot days and higher demand for electricity (i.e. increased use of air conditioners and other cooling units), the study also acknowledges how the grid could react to this extra demand for electricity during peak hours of the day.

A battery made with urea, commonly found in fertilizers and mammal urine, could provide a low-cost way of storing energy produced through solar power or other forms of renewable energy for consumption during off hours.

Developed by Stanford chemistry Professor Hongjie Dai and doctoral candidate Michael Angell, the battery is nonflammable and contains electrodes made from abundant aluminum and graphite. Its electrolyte’s main ingredient, urea, is already industrially produced by the ton for plant fertilizers.

“So essentially, what you have is a battery made with some of the cheapest and most abundant materials you can find on Earth. And it actually has good performance,” said Dai. “Who would have thought you could take graphite, aluminum, urea, and actually make a battery that can cycle for a pretty long time?”

In 2015, Dai’s lab was the first to make a rechargeable aluminum battery. This system charged in less than a minute and lasted thousands of charge-discharge cycles. The lab collaborated with Taiwan’s Industrial Technology Research Institute (ITRI) to power a motorbike with this older version, earning Dai’s group and ITRI a 2016 R&D 100 Award. However, that version of the battery had one major drawback: it involved an expensive electrolyte.

The newest version includes a urea-based electrolyte and is about 100 times cheaper than the 2015 model, with higher efficiency and a charging time of 45 minutes. It’s the first time urea has been used in a battery. According to Dai, the cost difference between the two batteries is “like night and day.” The team recently reported its work in the Proceedings of the National Academy of Sciences.

Many researchers agree that microbial fuel cells have a range of promising applications. However, before they can reach widespread applications, researchers need to make them both cheaper and more efficient.

A team of researchers from the University of Rochester believe they’re making progress on that front with the development of a paper electrode.

Microbial fuel cells drive electric current by using bacteria and mirroring bacterial interactions found in nature. In the 21st century, microbial fuel cells found new application in their ability to treat wastewater and harvest energy through anaerobic digestion.

This from University of Rochester:

Until now, most electrodes used in wastewater have consisted of metal (which rapidly corrodes) or carbon felt. While the latter is the less expensive alternative, carbon felt is porous and prone to clogging. Their solution was to replace the carbon felt with paper coated with carbon paste, which is a simple mixture of graphite and mineral oil. The carbon paste-paper electrode is not only cost-effective and easy to prepare; it also outperforms carbon felt.

Most of today’s batteries are made up of two solid layers, separated by a liquid or gel electrolyte. But some researchers are beginning to move away from that traditional battery in favor of an all-solid-state battery, which some researchers believe could enhance battery energy density and safety. While there are many barriers to overcome when pursing a feasible all-solid-state battery, researchers from MIT believe they are headed in the right direction.

This from MIT:

For the first time, a team at MIT has probed the mechanical properties of a sulfide-based solid electrolyte material, to determine its mechanical performance when incorporated into batteries.

Read the full article.

“Batteries with components that are all solid are attractive options for performance and safety, but several challenges remain,” says Van Vliet, co-author of the paper. “[Today’s batteries are very efficient, but] the liquid electrolytes tend to be chemically unstable, and can even be flammable. So if the electrolyte was solid, it could be safer, as well as smaller and lighter.”

While most car companies are investing research efforts into electric and autonomous vehicles, Uber – the highly popular ride-sharing service – is attempting to stick out in the crowd of auto giants by developing a flying car.

According to reports from Bloomberg, the company just took that goal one step further by hiring NASA veteran Mark Moore to work on company’s flying car project.

In less than a decade, Uber has changed the way many individuals think about transportation. Now, the company is looking to do that again. In October 2016, Uber announced plans for the “Elevate” network, which is set to function as a fleet of on-demand, electric aircrafts that take off and land vertically. Uber looks to implement Elevate within a decade.

Much like electric vehicles, the idea of the flying car is not new. In 1926, the concept even landed the cover of Popular Science. Still, there has never been a feasible technology to make this goal an actuality.
