Potatoes are great in many forms: mashed, baked, roasted, electrochemical energy source… Most people have seen or experienced the potato battery experiment in a chemistry class, but BatteryBox is taking this exercise to a whole new level.

As you know, one or two potatoes produce enough energy to power a small digital clock. But how much energy would 110 pound of potatoes produce? Enough to charge a smartphone?


For this experiment, the team at BatteryBox cut up and boiled the potatoes to increase the energy transfer. This allows for the harnessing of the full power of the potato.

Essentially, the team combined the 110 pounds of potatoes to create a galvanic cell.

The batteries have the ability to be integrated into the surface of the objects, making it seem like seem like there is no battery at all.

A new development out of the Ulsan National Institute of Science and Technology (UNIST) has yielded a new technique that could make it possible to print batteries on any surface.

With recent interests in flexible electronics—such as bendable screen displays—researchers globally have been investing research efforts into developing printable functional materials for both electronic and energy applications. With this, many researchers predict the future of the li-ion battery as one with far less size and shape restrictions, having the ability to be printed in its entirety anywhere.

The research team from UNIST, led by ECS member Sang-Young Lee, is setting that prediction on the track to reality. Their new paper published in the journal Nano Letters details the printable li-ion battery that can exist on almost any surface.

Scientists from Emory University are opening yet another door to renewable energy efforts. Their new way of performing light-driven reactions based on plasmon—the motion of free electrons that strongly absorb and scatter light—is said to be much more effective than previous processes.

“We’ve discovered a new and unexpected way to use plasmonic metal that holds potential for use in solar energy conversion,” says Tim Lian, professor of physical chemistry at Emory University and the lead author of the research. “We’ve shown that we can harvest the high energy electrons excited by light in plasmon and then use this energy to do chemistry.”

To get a better understanding of surface plasmonic, just think of how a cathedral’s stained glass windows absorb and shatter light.

Researchers involved in this study believe their plasmonic centered process could apply to efforts in electronics and renewable energy. Using plasmon could potentially make light-driven charge transfer for solar energy conversion much more efficient.

Energy is everywhere. As long as there has been a universe, there has been energy. In fact, some researchers believe that Earth’s very first life forms got a little electrical energy boost from chemical seafloor gardens.

Of course this was only a theory, so scientists at the Jet Propulsion Laboratory have grown their on chemical gardens in-house. The have proven strong enough to power a lightbulb, suggesting that the first cell-like organisms may indeed have used seafloor, chimney-shaped structures to channel electricity.

“These chimneys can act like electrical wires on the seafloor,” said Laurie Barge of NASA’s Jet Propulsion Laboratory. “We’re harnessing energy as the first life on Earth might have.”

These findings help researchers explore more definitive answers to the question of life on earth and how it all started. The idea of the seafloor chemical garden agrees with an already established scientific theory—alkaline vent hypothesis—that leans toward the idea that life started underwater due to warm, alkaline chimneys.

“Life doesn’t want to get electrocuted, but needs just the right amount of electricity,” said Michael Russell of Jet Propulsion Laboratory. “This new experiment confirms what that amount of electricity is – just under a volt.”

Introducing Graphene’s Cousin: Stanene

Stanene-LatticeResearchers made a prediction two years ago that a one-atom thick, tin super material would soon be developed. They believed that this mesh material would yield amazing advances for materials science and be able to conduct electricity with 100 percent efficiency. Now, those same researchers are making good on their prediction with the announcement of the newly developed film called stanene.

Theoretically, potential uses of this material could range from circuit structures to transistors.

Cousin to graphene, this lattice of carbon atoms has similar qualities to a host of other materials, but scientists predict stanene to have a special kick that no other material has yet.

Actress, comedian, and author Amy Poehler has put a lot of effort into empowering young girls in science for some time now. Her Smart Girls project took off in 2008, which serves as a place where future women can foster their curiosity and pursue opportunities in STEM. Now Poehler and her Smart Girls group are adding to the women in STEM conversation with their new series, “Experimenting with Megan Amram.”

Amram is a Harvard graduate, author, and comedian. The new web series serves as a perfect platform to continue what she already started in her book Science… for Her!. The parody science text is comedic in nature, but takes a hard look at the gender gap in STEM and offers up some pretty solid science as well.

As an added bonus, you can even get a step-by-step instructions on how to conduct Amram’s experiments.

There are more than 250 million cars and trucks on U.S. roads. From these vehicles, roughly 135 billion gallons of gasoline are consumed each year in the United States. In fact, 28 percent of energy used in the country is in the transportation sector.

While many may think that the majority of this consumption would come from planes or trains, personal cars and trucks actually consume 60 percent of all energy used here. Unfortunately, most of that energy is lost to heat and other inefficiencies within the vehicles, leaving only about 10 to 16 percent of a car’s fuel being used to actually drive and overcome road resistance.

However, the researchers at Virginia Tech may have a partial solution to this problem: harvesting energy from a car’s suspension.

es-2015-008758_0004The cleaning of industrial wastewater is a persistent issue across the globe. If left untreated, these harmful waters could enter open watercourses, dispersing contaminants such as mercury and lead. Not only is this an immediate health risk, but it also threatens the entire ecosystem.

Modern wastewater treatment plants have been able to treat the water, but have not been very environmentally conscious. The typical plant produces CO2 by burning fossil fuels for power and the general decomposition of the materials in the wastewater. Not to mention, these things require a lot of power. About 12 trillion gallons of wastewater gets treated each year in the United States along, consuming an alarmingly high 3 percent of the nation’s energy grid.

Researchers have already produced power from pee and made poop potable; so why not develop a new type of wastewater treatment device that significantly lessens the severity of CO2 emissions and simultaneously captures greenhouse gases?
