Zoom CEO Eric Yuan told staff an all-hands meeting earlier this month that he wants employees to return to in-person work because Zoom is making them too “friendly” and unable to build trust. “Over the past several years, we’ve hired so many new ‘Zoomies’ that it’s really hard to build trust,” Mr Yuan says in the audio, which was obtained and first reported by Insider. “We cannot have a great conversation. We cannot debate each other well because everyone tends to be very friendly when you join a Zoom call.” Mr Yuan’s thoughts were accompanied by action: On 3 August, Zoom instituted a new policy requiring employees who live within 50 miles of a physical Zoom office to report to work at least two days per week. The return to the office policy at Zoom is striking considering that it was the Covid-19 pandemic and resulting stay-at-home orders that turned the platform from one few people had ever heard of to a part of everyday life for millions. But Mr Yuan is not alone among senior executives at tech firms. Apple, Meta, and Amazon have all instituted return-to-work policies in recent months, angering employees who have enjoyed the increased flexibility afforded by work-from-home policies. Since Covid-19 vaccines have facilitated the re-opening of the economy, workers and bosses in many sectors have clashed over the importance of in-person work and the ability of companies to exercise control over their employees whereabouts and schedules. Some, like Zoom and a number of other tech companies, have adopted hybrid policies in which workers are required to come into the office on certain days of the week but are allowed to work from home on others. But even those companies have faced backlash from workers, many of whom were hired at a different stage of the pandemic when most or all work at their respective companies was being conducted remotely. Mr Yuan’s comments, which were not meant for public consumption, may provide a measure of insight into how he and other top executives truly feel about Zoom and remote work more broadly — suggesting that it somehow limits innovation by not allowing for the sometimes uncomfortable kinds of interactions that can build trust. Mr Yuan, who was born and raised in China, moved to Silicon Valley during the late 1990s. He founded Zoom more than a decade ago and became a multibillionaire during the pandemic.

Researchers have come up with a new way to generate electricity with solar panel technology by harvesting the energy produced by raindrops. The method, proposed by a team from Tsinghua University in China, involves a device called a triboelectric nanogenerator (TENG) that creates electrification from liquid-solid contact. These are typically used to harvest energy from waves, as droplet-based TENGs (D-TENGs) have previously faced technical limitations that prevented them from working at any significant scale. By using solar panel bridge arrays, the researchers discovered such barriers could be overcome “Referring to the design of solar panels in which multiple solar power generation units are connected in parallel to supply the load, we are proposing a simple and effective method for raindrop harvesting,” said Professor Zong Li, who led the research. “The peak power output of the bridge array generators is nearly five times higher than that of the conventional large-area raindrop energy harvesting. The results of this study will provide a feasible scheme for large-area raindrop energy harvesting.” A study detailing the breakthrough, titled ‘Rational TENG arrays as a panel for harvesting large-scale raindrop energy’, was published in the journal iEnergy. “As an important part of the natural energy and water cycle, rainfall contains abundant renewable energy,” the study notes. “However, this kind of renewable energy lacks effective utilisation today... Therefore, finding a reasonable topology to relieve the inherent constraints of D-TENGs is of great significance for realising the large-scale raindrop energy harvesting.” It is one of a number of promising advances with solar panel technology in recent months, with an Australian team of researchers developing self-healing cells capable of recovering 100 per cent of their original efficiency after suffering degradation from space radiation. Earlier this week, scientist’s at the US Department of Energy’s National Renewable Energy Laboratory (NREL) unveiled a design for a double-sided solar panel capable of boosting efficiency rates by up to 20 per cent by harvesting reflected sunlight.
