Study: New reusable shock absorber shows promise in lab tests

The images show the device bending and snapping to dissipate energy. Credit: University at Buffalo University at Buffalo engineers are reporting a new energy dissipation device that they say could have far-reaching applications in transportation safety. Described in the International Journal of Mechanical Sciences, the device utilizes low-cost metallic materials...

Microwave-powered rocket propulsion investigated

Microwave-powered rocket propulsion investigated

Credit: Montri Nipitvittaya/Shutterstock Sending a rocket into space typically requires about 90% of the rocket's initial weight to be fuel. This limitation could be overcome by wirelessly transmitting the needed power to the rocket through a beam of microwave radiation. A research team from Japan has investigated the viability of...
