Stanford’s DeepSolar neural network analyzed satellite images to count U.S. solar installations—and there are a lot more than anybody thought There are at least 1.47 million solar installations of varying sizes in the 48 contiguous U.S. states, from home rooftop panels to utility-owned solar power plants. That’s the conclusion of DeepSolar, a machine learning algorithm developed by researchers at Stanford University that searches satellite images for solar panels. The count is higher than some previous estimates, like the OpenPV project’s count of 1.02 million installations.
Cheaper plant sensors could bring monitoring to individual plants on a massive scale Stretchable plant wearables and smart tags dropped by drones aim to help give farming a big data makeover. The relatively cheap technologies for mass monitoring of individual plants across large greenhouses or crop fields could get field tests in three countries starting in 2019.
To make drone package delivery green, look at drone size, electricity source, and warehouses, researchers say Illustration: iStockphoto Drone delivery is expected to take off big time in the next few years. Chinese online retailer JD.com has already launched drone delivery in four provinces in China, while DHL and Zipline are delivering medicines with drones in rural and hard-to-reach areas. Amazon , Google, and UPS are all working on getting drone delivery service off the ground. There are a lot of issues to think about when it comes to package delivery using drones—safety, privacy, and logistics being some of the main concerns. In a new study, researchers tackle two other important aspects: energy use and greenhouse gas emissions. Drones could use less energy and spew fewer emissions into the air than trucks, researchers say. But that advantage diminishes as drones get bigger and use dirty electricity to recharge. “If you’re delivering a Continue reading Drone Delivery, If Done Right, Could Cut Emissions
