Solar-Powered Water Wheels Prevented 1 Million Pounds of Trash From Entering Baltimore Harbor
Meet Mr. Trash Wheel and Professor Trash Wheel—a pair of floating, solar and hydro-powered trash interceptors keeping Baltimore's waters clean. These frankly adorable trash wheels can collect as much as 38,000 pounds of debris in a single day.
Mr. Trash Wheel, located at the mouth of Jones Falls, has stopped more than one million pounds of garbage from entering Baltimore's Inner Harbor since its installation in May 2014. Because it has been so effective, a second water wheel, "Professor Trash Wheel," was installed at Harris Creek Park in Canton and opened this past December.
Professor Trash Wheel has googly eyes like Mr. Trash Wheel but with eyelashes.
The anthropomorphized wheels have become so popular they have their own merchandise, their own social media pages (Mr. Trash Wheel: Twitter and Facebook; Professor Trash Wheel: Twitter and Facebook) and have done several amusing AMAs on Reddit.
When one Redditor asked, "If there were a 6th season of The Wire centering around trash in the Inner Harbor, what would the main plot points be? What roles would you and Professor Trash Wheel play?"
Mr. Trash Wheel responded:
"Here's the plot: Trash is over flowing the streets of Baltimore. Trash storms plague the city on a regular basis and micro plastics have formed a choking fog that sits on the city at all times. Professor Trash Wheel believes she can work within the system to get litter of the streets. She creates coalitions with nonprofits and government agencies to battle the rising tide of trash. Mr. Trash Wheel obeys no law or man. He goes rogue attacking trash on the streets, in the harbor, wherever he can find it. Who will win out? Find out on Season 6 of the Wire. David Simon, you have my number. Stop ignoring my texts"
The iconic harbor is "polluted by millions of gallons of sewage, hundreds of tons of trash, and stormwater runoff are polluting the harbor and streams every year," the local environmental nonprofit states on its website.
"These conditions are threatening the lives of the fish, crabs, turtles, birds, and river otters that are part of the harbor, and even simple contact with the water can be dangerous due to the threat of waterborne diseases."
The Baltimore Sun reported that local environmentalists would like to see at least two more water wheels to address the city's litter problem.
So how do these devices work? Using water currents, trash and debris floats into containment booms in front of the wheel. The trash moves onto a conveyor belt that leads to a dumpster barge. When the dumpster is full, the trash is towed away. A backup solar panel array powers the wheel when the current is not strong enough.
The collected material is weighed and separated into different categories: plastic bottles, polystyrene containers, cigarette butts, glass bottles, grocery bags and chip bags. Some of the trash is incinerated to help generate electricity for the city.
The trash wheel's creator, John Kellett, told National Geographic that it's a common misconception that people are littering directly into the water. Instead, most of the garbage—such as trash thrown from cars, illegal dumping and cigarettes butts—ends up in the watershed after it rains.
"If it rains, there is always trash," Kellett told the publication.
In about two-and-a-half years, Mr. Trash Wheel has picked up almost nine million cigarette butts and more than 300,000 plastic bags. It also picks up an average of 14,000 Styrofoam containers a month.
According to National Geographic, "the data is used to support environmental legislation. For example, the Waterfront Partnership recently supported a bill that would ban Styrofoam containers."

Neil Pederson's introduction to tree rings came from a "sweet and kindly" college instructor, who nevertheless was "one of the most boring professors I'd ever experienced," Pederson said. "I swore tree rings off then and there." But they kept coming back to haunt him.

Links between excess sugar in your diet and disease have been well-documented, but new research by Harvard's School of Public Health might make you even more wary of that next soda: it could increase your risk of an early death.
The study, published this week in the American Heart Association's journal Circulation, found that drinking one or two sugar-sweetened beverages (SSBs) each day — like sodas or sports drinks — increases risk of an early death by 14 percent.
Tyson Foods Recalls Nearly 70,000 Pounds of Chicken Strips After Customers Find ‘Fragments of Metal’
Tyson Foods is recalling approximately 69,093 pounds of frozen chicken strips because they may have been contaminated with pieces of metal, the U.S. Department of Agriculture (USDA) Food Safety and Inspection Service (FSIS) announced Thursday.
The affected products were fully-cooked "Buffalo Style" and "Crispy" chicken strips with a "use by" date of Nov. 30, 2019 and an establishment number of "P-7221" on the back of the package.
"FSIS is concerned that some product may be in consumers' freezers," the recall notice said. "Consumers who have purchased these products are urged not to consume them. These products should be thrown away or returned to the place of purchase."
Environmental exposure to pesticides, both before birth and during the first year of life, has been linked to an increased risk of developing autism spectrum disorder, according to the largest epidemiological study to date on the connection.
The study, published Wednesday in BMJ, found that pregnant women who lived within 2,000 meters (approximately 1.2 miles) of a highly-sprayed agricultural area in California had children who were 10 to 16 percent more likely to develop autism and 30 percent more likely to develop severe autism that impacted their intellectual ability. If the children were exposed to pesticides during their first year of life, the risk they would develop autism went up to 50 percent.
