"Better" copper means higher-efficiency electric motors

Researchers at Pacific Northwest National Laboratory (PNNL) have increased the conductivity of copper wire by about five percent. That may seem like a small amount but it can make a big difference in motor efficiency. Higher ...

The smallest motor in the world

A research team from Empa and EPFL has developed a molecular motor which consists of only 16 atoms and rotates reliably in one direction. It could allow energy harvesting at the atomic level. The special feature of the motor ...

Rat spinal cords control neural function in biobots

Biological robots, or biobots, draw inspiration from natural systems to mimic the motions of organisms, such as swimming or jumping. Improvements to biobots to better replicate complex motor behaviors can lead to exciting ...

Eco-bike aims to cut pollution in Kathmandu

Where there's a will, there's a way. The truth of that saying was revealed once again to Lance Rake when he traveled to Kathmandu, Nepal, last year to develop a delivery version of the bamboo bicycles for which he is known.

Super magnets from a 3-D printer

Magnetic materials are an important component of mechatronic devices such as wind power stations, electric motors, sensors and magnetic switch systems. Magnets are usually produced using rare earths and conventional manufacturing ...

Sustainable 3D-printed super magnets

From wind turbines and electric motors to sensors and magnetic switching systems, permanent magnets have many electrical applications. The production of these magnets usually involves sintering or injection molding. But due ...

Automakers side with Trump in legal fight with California

General Motors, Fiat Chrysler, Toyota and 10 smaller automakers are siding with the Trump administration in a lawsuit over whether California has the right to set its own greenhouse gas emissions and fuel economy standards.
