Scientists develop way to upsize nanostructures into light, flexible 3D printed materials
Posted by Shailesh Prasad in categories: 3D printing, energy, engineering, nanotechnology
For years, scientists and engineers have synthesized materials at the nanoscale level to take advantage of their mechanical, optical, and energy properties, but efforts to scale these materials to larger sizes have resulted in diminished performance and structural integrity.
Now, researchers led by Xiaoyu “Rayne” Zheng, an assistant professor of mechanical engineering at Virginia Tech have published a study in the journal Nature Materials that describes a new process to create lightweight, strong and super elastic 3D printed metallic nanostructured materials with unprecedented scalability, a full seven orders of magnitude control of arbitrary 3D architectures.
Strikingly, these multiscale metallic materials have displayed super elasticity because of their designed hierarchical 3D architectural arrangement and nanoscale hollow tubes, resulting in more than a 400 percent increase of tensile elasticity over conventional lightweight metals and ceramic foams.

This Tablet-Toting Military Vest Is Actually a Giant Battery
Posted by Karen Hurst in categories: energy, military, mobile phones
Smartphones and tablets are being used more frequently in the battlefield, and that means that battery power is more important than ever. Soldiers often carry spare battery chargers in the 90-pound combat packs they carry into war zones, but the batteries are often lost or broken. BAE Systems wants to help lighten the load with its new system that lets soldiers plug electronics directly into their clothing.
The BAE Systems Broadsword Spine is a harness that can be sewn into a soldiers vest, jacket, or belt that carries a battery pack and hides charging wires. The harness places the battery pack on the small of a soldier’s back and includes eight conductive fabric conduits that can be used to connect to a USB port.

How Nikola Tesla Used ‘Spirituality’ & Philosophy To Learn About Reality, ‘Limitless’ Energy & Science
Posted by Karen Hurst in categories: employment, energy, neuroscience, science
I will say that many great innovators and inventors had some sort of spiritualism that they drew from to provide another angle on how to see/ perfect an idea or innovation. Jobs, Tesla, Edison, Bell, da Vinci, Carver, etc.
The Properties of Space.

Sweden debuts the world’s first ‘electric highway’
Posted by Shailesh Prasad in categories: energy, transportation
Underground wireless charging will be a better idea!
Fossil fuels are bad for the planet, and freight haulage is one of the more carbon-intensive activities that operate today. That’s why Siemens and Scania have teamed up to trial what’s being called the world’s first “electric highway.” Much like an electrified railroad, the 1.2 mile stretch has a series of wires hanging overhead that a pantograph-equipped truck can connect to. Then, the vehicle can deactivate its fuel-burning engine and coast along on that delicious, dirt-cheap electricity, switching back when the wires stop.
Scania official Claes Erixon has said that the project is “one important milestone on the journey towards fossil-free transport.” Cleantech Canada quotes an unnamed Siemens representative, who says the move could cut energy consumption in half. As it stands, this is the culmination of a two-year project to develop this test track, with more work to be done to determine if it could be rolled out across the country. That is, unless, an alternative freight-transport network that’s even more energy-efficient and speedy, can make its case to governments across the world.
