    FTC and DOJ Think McDonald's Ice Cream Machines Should Be Legal To Fix
    The Federal Trade Commission and the Department of Justice have urged the US Copyright Office to broaden exemptions to the Digital Millennium Copyright Act's Section 1201. Specifically, the two agencies are advocating for the extension of the right to repair to include "commercial and industrial equipment," which includes McDonald's ice cream machines that are notorious for breaking down. The Verge reports: Exemptions to DMCA Section 1201 are issued every three years, as per the Register of Copyrights' recommendation. Prior exemptions have been issued for jailbreaking cellphones and repairing certain parts of video game consoles. The FTC and DOJ are asking the Copyright Office to go a step further, extending the right to repair to "commercial and industrial equipment." The comment (PDF) singles out four distinct categories that would benefit from DMCA exemptions: commercial soft serve machines; proprietary diagnostic kits; programmable logic controllers; and enterprise IT. 'In the Agencies' view, renewing and expanding repair-related exemptions would promote competition in markets for replacement parts, repair, and maintenance services, as well as facilitate competition in markets for repairable products," the comment reads. The inability to do third-party repairs on these products not only limits competition, the agencies say, but also makes repairs more costly and can lead to hundreds or thousands of dollars in lost sales. Certain logic controllers have to be discarded and replaced if they break or if the passwords for them get lost. The average estimated cost of "unplanned manufacturing downtime" was $260,000 per hour, the comment notes, citing research from Public Knowledge and iFixit. As for soft serve machines, breakdowns can lead to $625 in lost sales each day. Business owners can't legally fix them on their own or hire an independent technician to do so, meaning they have to wait around for an authorized technician -- which, the comment says, usually takes around 90 days.

    Caffeine Makes Fuel Cells More Efficient, Cuts Cost of Energy Storage
    Dan Robinson reports via The Register: Adding caffeine can enhance the efficiency of fuel cells, reducing the need for platinum in electrodes and significantly reducing the cost of making them, according to researchers in Japan. [...] The study, published in the journal Communications Chemistry, concerns the catalysis process at the cathode of a fuel cell and making this reaction more efficient. Fuel cells work somewhat like batteries. They generate power by converting the chemical energy of a fuel (or electrolyte) and an oxidizing agent into electricity. This is typically hydrogen as a fuel and oxygen as an oxidizer. Unlike batteries with limited lifespans, fuel cells can generate power as long as fuel is supplied. The hydrogen undergoes oxidation at the anode, producing hydrogen ions and electrons. The ions move through the hydrogen electrolyte to the cathode, while the electrons flow through an external circuit, generating electricity. At the cathode, oxygen combines with the hydrogen ions and electrons, resulting in water as a by-product. However, this water impacts the performance of the fuel cell, reacting with the platinum (Pt) to form a layer of platinum hydroxide (PtOH) on the electrode and interfering with the catalysis of the oxygen reduction reaction (ORR), according to the researchers. To maintain efficient operation, fuel cells require a high Pt loading (greater platinum content), which significantly ups the costs of fuel cells. A quick look online found market prices for platinum of $29.98 per gram, or $932.61 per ounce, at the time of writing. The researchers found that adding caffeine can improve the ORR activity of platinum electrodes 11 fold, making the reaction more efficient. If you are wondering (as we were) how they came to be experimenting with this, the paper explains that modifying electrodes with hydrophobic material is known to be an effective method for enhancing ORR. Caffeine is less toxic than other hydrophobic substances, and it activates the hydrogen evolution and oxidation reactions of Pt nanoparticles and caffeine doped carbons. Got that? Chiba University's work was led by Professor Nagahiro Hoshi at the Department of Applied Chemistry and Biotechnology. He explained that the researchers found a notable improvement in the electrode's ORR activity with an increase in caffeine concentration in the electrolyte. This forms a thin layer on the electrode's surface, effectively preventing the formation of PtOH, but the effect depends on the orientation of the platinum atoms on the electrode's surface. The paper refers to these as Pt(100), Pt(110) and Pt(111), with the latter two showing increased ORR activity, while there was no noticeable effect with Pt(100). The researchers do not explain if this latter effect might be a problem, but instead claim that their discovery has the potential to improve the designs of fuel cells and lead to more widespread adoption.

    Mercedes is Trialing Humanoid Robots For 'Low Skill, Repetitive' Tasks
    Mercedes-Benz is the latest automotive company to trial how humanoid robots could be used to automate "low skill, physically challenging, manual labor." From a report: On Friday, robotics company Apptronik announced it had entered into a commercial agreement with Mercedes to pilot how "highly advanced robotics" like Apollo -- Apptronik's 160-pound bipedal robot -- can be used in manufacturing. The news follows a similar pilot announced by BMW in January. Apptronik says that Mercedes is exploring use cases like having Apollo inspect and deliver components to human production line workers. Neither company has disclosed any figures for the agreement or how many Apollo robots are being trialed. According to Apptronik, humanoid robots would allow vehicle manufacturers to start automating manufacturing tasks without having to redesign their existing facilities. The company says its approach instead "centers on automating some physically demanding, repetitive and dull tasks for which it is increasingly hard to find reliable workers."
