Clean, renewable wind energy now accounts for more than 8% of the U.S. s electricity generation, up from about 4% in 2014, according to the U.S. Energy Information Administration. In March, President Joe Biden announced a plan to expand offshore wind energy projects, part of a larger initiative to vastly increase the country s renewable energy production and reduce greenhouse gas emissions by 2030. Last week, the administration officially approved the country s first major offshore wind farm near Massachusetts.
But large-scale wind farms present new engineering challenges. Classical engineering models formerly used to estimate power output for moderately sized wind farms don t always work reliably for today s larger wind farms, where complex turbine arrangements are more common, Gayme says.
Researchers from Johns Hopkins and Drexel universities say that adding haptics an artificial sense of touch to upper limb prostheses reduces the mental effort required to operate the device, bringing us closer to developing prosthetic technology that functions more like healthy limbs.
In what researchers are calling the first study of its kind, the cross-institutional team used neuroimaging to investigate if haptic feedback would help people who use prosthetic hands to expend less mental effort while carrying out tasks. The team s findings were published today in
