An infographic by Jeffrey Winters uses data from the Bureau of Economic Analysis to illustrate the US' struggles to bridge the gap between imports and exports. Policy solutions remain elusive, although US exports managed to register some improvement between H2 2015 and H2 2019 before the coronavirus pandemic struck.
The Role of a Squeeze Film Damper While fluid film bearings provide a significant amount of damping, it may not be sufficient for all machine designs. An additional means of increasing "effective" damping may be required to control vibrations. Explore conventional versus integral squeeze film damper designs. Learn more.
The Canadian Space Agency is working with a hydroponic community greenhouse project in Nunavut to study growing conditions above the Arctic Circle that could teach researchers how to grow food in space. "This is really focused on maximizing the green stuff we can get with the smallest amount of resources," agency engineer Matthew Bamsey said.
Artificial intelligence can process more engineering design options at the conceptual stage than humans, which is one of four ways how AI and big data can improve manufacturing, Beth Stackpole writes. "Where machines bring their strength, repeatability, and precision, humans can bring their flexibility, judgment, and dexterity," says Veo Robotics Chief Technology Officer Clara Vu.
Hyperion has released renderings of its XP-1 hydrogen supercar, which will feature articulating solar panels and carbon fiber storage systems. The chassis will feature a carbon-titanium metal-composite monocoque and the bodywork will be titanium-reinforced composite.
Researchers at Oxford University, in collaboration with Reaction Engines, are developing technology to power airplanes with ammonia, which would be safer than kerosene and allow for emission-free air travel. The new fuel could still be placed in the wings, so current aircraft could be adapted rather than needing to be overhauled or replaced.
The Navy is employing 3D printing and nanophotonics to create and test tiny models of submarines and other warships for their radar profiles. The technique is considered more efficient and accurate than computer modeling.
Junroe Barrios, an agricultural engineer from the Philippines, designed face shield frames made from bamboo. The Philippines' Mindanao Development Authority is promoting its use in light of the COVID-19 pandemic.
Vineyard Wind and Greentown Labs have chosen three startups to participate in the Offshore Wind Challenge, a six-month accelerator for new technologies that protect marine life near offshore wind sites. The selected startups specialize in aerial drones, camera systems and solar-powered autonomous boats.
Digital transformation is something most industrial firms desire, but the difficulty is in the execution of "outcomes and business process transformation,"says GE Digital CEO Pat Byrne. Rounding out a year in the job, Byrne explores how companies are pursuing transformation by focusing on return on investment, capturing their most useful data and seeking suppliers that understand the company's needs and its industry.
