MIT researchers have developed a portable desalination unit, weighing less than 10 kilograms, that can remove particles and salts to generate drinking water.

The suitcase-sized device, which requires less power to operate than a cell phone charger, can also be driven by a small, portable solar panel, which can be purchased online for around $50. It automatically generates drinking water that exceeds World Health Organization quality standards. The technology is packaged into a user-friendly device that runs with the push of one button.

Unlike other portable desalination units that require water to pass through filters, this device utilizes electrical power to remove particles from drinking water. Eliminating the need for replacement filters greatly reduces the long-term maintenance requirements.

This could enable the unit to be deployed in remote and severely resource-limited areas, such as communities on small islands or aboard seafaring cargo ships. It could also be used to aid refugees fleeing natural disasters or by soldiers carrying out long-term military operations.

"This is really the culmination of a 10-year journey that I and my group have been on. We worked for years on the physics behind individual desalination processes, but pushing all those advances into a box, building a system, and demonstrating it in the ocean, that was a really meaningful and rewarding experience for me," says senior author Jongyoon Han, a professor of electrical engineering and computer science and of biological engineering, and a member of the Research Laboratory of Electronics (RLE).

Joining Han on the paper are first author Junghyo Yoon, a research scientist in RLE; Hyukjin J. Kwon, a former postdoc; SungKu Kang, a postdoc at Northeastern University; and Eric Brack of the U.S. Army Combat Capabilities Development Command (DEVCOM). The research has been published online in Environmental Science and Technology.

Demand is increasing for computers that can quickly calculate and process large amounts of information, as artificial intelligence, self-driving cars, drones, and metaverse technologies are drawing attention as core industries of the future. However, electronic semiconductor logic gates, which serve as the brains of computers today, have limited capacity in high-speed data calculation and processing, and have disadvantages in that they consume a lot of energy and generate considerable heat.

Research teams at KIST and Gwangju Institute of Science and Technology, led by Dr. Yusin Pak at the Sensor System Research Center (KIST) and Professor Gun Young Jung at the School of Materials Science and Engineering (GIST), have developed ultra-high-speed, high-efficiency optoelectronic logic gates (OELGs) by using organic-inorganic perovskite photodiodes.

The optoelectronic logic gate has high-speed and high-efficiency characteristics; it uses light as an input signal, and demonstrates low energy loss physically, and can operate without electrical power supply using only light energy. The research teams implemented a stacked perovskite optoelectronic logic gate. Two layers of perovskite thin films are vertically stacked like a sandwich and proved that the desired binary logic operation is possible by inputting two lights of different wavelengths and intensities.

As the perovskite optoelectronic logic gate can freely change the photocurrent polarity using light, executing more than one logic gate operation result for the same input value is possible. Therefore, compared to the existing logic gate that can only perform one logical operation on one device, the newly developed one can implement all five different basic logic operations such as AND, OR, NAND, NOR, and NOT. It enables the development of optical processors with high spatial efficiency and integration, as one logic gate can function like five logic gates.

Robin Murphy, a roboticist at Texas A&M University has published a Focus piece in the journal Science Robotics outlining her views on the robots portrayed in "Star Wars," most particularly those featured in "The Mandalorian" and "The Book of Boba Fett." In her article, she says she believes that the portrayals of robots in both movies are quite creative, but suggests they are not wild enough to compete with robots that are made and used in the real world today.

Murphy begins by noting that one robot in particular, IG-11 in the Mandalorian, makes for good viewing with a rotating head that allows for shooting at targets in any direction, but she also notes that such a robot would very likely be overly susceptible to joint failure and would be saddled with huge computational demands. She suggests a more practical design would involve the use of fixed-array sensors.

Murphy also notes that robots in "Star Wars" movies do fail on occasion, generally during suspenseful scenes, which she further notes might explain why the empire met with its demise. As just one example, she wonders why the stormtroopers so often miss their targets. She also notes that in some ways, droids in "Star Wars" movies tend to be far more advanced than droids in the real world, allowing them to hold human-like jobs such as bartending, teaching or translating. In so doing, she points out, producers of the movies have shied away from showing them doing more mundane work, like mining.

In the real world, she points out, robots are increasingly filling laborious roles traditionally carried out by humans. Automating mining in the real world, she notes, has led to a major drop in human labor costs over the past 20 years. She also wonders why drones are so seldom featured in "Star Wars" movies, noting that in the real world, they have become a major part of warfare efforts. She notes that in a real space endeavor, a drone is currently helping a rover on Mars avoid patches of ground where it might get stuck.

Murphy concludes that one of the things the movies get right is the joy that roboticists can bring to those who benefit from the design and creation of imaginative robots in so many areas of life.
