Small modular reactor potential lies in industry, not grid power

A technoeconomic assessment of small modular reactor (SMR) development across the United States suggests stakeholders should shift focus from the power sector to industry, according to a University of Michigan Engineering ...

Autonomous robots gain high-resolution radar that avoids 88% of unnecessary computations

Radar, a key sensor for autonomous mobile robots, uses radio waves to determine the distance, speed and direction of surrounding obstacles. Because it operates reliably even under adverse weather conditions, such as rain, ...

Insect-inspired corrugations could help drones fly in Mars-like thin air

Researchers from Tokyo Metropolitan University have used an evolutionary algorithm to identify optimal shapes for ultra-thin, bio-inspired corrugated airfoils, the two-dimensional cut-throughs of wings. Lightweight membrane-like ...

Carbon imperfections could replace scarce metals in future clean-hydrogen production

The global transition toward carbon-free, clean and sustainable energy has accelerated the search for new hydrogen-producing technologies. However, making clean hydrogen by splitting water into hydrogen and oxygen is expensive ...

Strengthening wood with needle and thread

Wood laminates are used in many different ways, for example, in the manufacture of skis and snowboards or in components for vehicle interiors. However, their weight advantages for lightweight construction also have disadvantages. ...

What 100,000 simulations reveal about the US power grid

On August 13, 2003, a single transmission line near Cleveland, Ohio, sags into an overgrown tree limb and short circuits. Within minutes, nearby lines overload and trip one after another, triggering cascading failures across ...

Why solid-state batteries keep short-circuiting

Batteries that use solid metal as their charge-carrying electrolyte could potentially be a safer and far more energy-dense alternative to lithium-ion batteries. Unfortunately, these solid-state batteries have been plagued ...

Harvesting heat and electricity from the sun, when you need it

Solar energy is abundant and frustratingly ill-timed. A sunbeam can become either electricity (useful for running modern life) or heat (useful for keeping spaces warm). But conventional solar hardware is single-minded: Photovoltaic ...

Mach 1.5 tests reveal noise feedback loops from supersonic jets

Researchers from the FAMU-FSU College of Engineering and the Florida Center for Advanced Aero-Propulsion, or FCAAP, are helping to solve a safety challenge in military aviation: the extreme noise generated by supersonic jets ...

New bifacial solar cells yield efficiencies above 32%

Solar cells, devices that can convert sunlight into electricity, are now widely used in many countries worldwide. Over the past few years, energy engineers have been exploring alternative designs that could further boost ...
