Martin Bazant, MIT professor of mathematics, who built an interactive model that predicts the infectiousness of COVID-19 in different environments, suggests “running strong ventilation, ideally with HEPA air filtration, and opening windows with fans for a few hours before resuming normal occupancy without masks,” he says. In other words, strategic use of windows, fans, and HEPA filters could clear the White House air in less than a day. David Edwards, Harvard bioengineering researcher and entrepreneur, adds that, “There will be dead zones where air does not circulate well—desks, seats, couches, bathrooms,” he says. These places should be identified and addressed by circulating and filtering the air. (A portable HEPA filter could handle that.) … [Read more...] about You can’t use bleach to sterilize the White House. Here’s what experts recommend instead
This will come down to changing consumer behavior, which isn’t an easy task. Until recently, there was often a stigma associated with buying used products, but the wave of online resale platforms have helped rebrand it. These companies often market themselves as a way to get good deals on coveted products, but they also make the case that it’s more eco-friendly to buy used. This argument appears to be working: Thredup commissioned a study which found that many shoppers—particularly younger ones—feel proud to shop secondhand, while they feel guilty about buying fast fashion, which they see as less sustainable. … [Read more...] about Poshmark’s explosive IPO bodes well for the resale industry, but how sustainable is secondhand?
Two years ago, before COVID-19 hit, Swiss International Air Lines hired me to reinvent the concept of economy-class travel. At least, that was the presenting problem. When I met with members of senior management, it was clear they had certain aesthetic fixes in mind—changing the welcome messages on the video screens, softening the glare of the reading lights, improving the snack selection, etc. I told them that before I could even think about welcome messages, lighting, or snacks, I needed to figure out the real reasons why repeat passenger levels had dropped and why the airline ranked #18 for on-time arrivals. … [Read more...] about Three shockingly obvious ways to make flying less miserable
how technology might enable rewilding in the U.K. and Europe. Riggall had begun thinking about the historical landscape when he studied environmental archaeology as a university student. “My first introduction to the concept that Europe had a wildwood was through the archaeological record,” he says. Over the years, as he worked in the climate change sector, he noticed a disparity in how that past was discussed—developing countries would be criticized for cutting down forests to farm, but few people talked about the fact that the same thing had happened earlier in Europe at a massive scale, and again when Europeans arrived in America. … [Read more...] about Why we need to “rewild” our environment
While some indoor farms incorporate as much automation as possible, AppHarvest plans to rely on humans. The facility will provide 100 construction jobs and 285 full-time, permanent jobs that pay a minimum of $13 an hour plus benefits. “We feel like this is the next generation of farming,” he says. “We want our farmers to have the tools and be at the forefront, so we will layer in technology over time to continue to drive efficiency inside of our facility. But for us, we feel that having a human touch in the middle of food production is something that’s still important.” … [Read more...] about This startup is going to put one of the world’s largest sustainable greenhouses in coal country
