MIT creates an intelligent power supply lets hardware sip energy

low-energy Researchers at MIT have created a power supply for small electronic devices that “sips” energy by turning devices on with packets of energy rather than a steady stream. Most power converters release a steady voltage. This means they’re generally inefficient for small devices like sensors and other devices that don’t need to be constantly on. The MIT’s… Read More

The Markforged Metal X prints real metal parts

screen-shot-2017-01-06-at-12-27-34-pm The new Markforged Metal X is pretty great. It is a full metal 3D printer that generates real metal parts out of powdered metal which is then hardened under massive heat and allows for amazingly strong and light materials. The printer uses tubes of powered metal bound with plastic. The “extruder” first creates the shapes on a regular build plate and then you bond the material in… Read More

The U.S. Navy is using drone boat swarms to keep harbors safe

screen-shot-2016-12-20-at-10-26-50-am The U.S. Navy is testing a team of drone boats to protect harbors here and abroad. The boats, which are basically autonomous versions of the Rigid Hull Inflatable, are connected to a AI routing system called CARACaS. In original 2014 tests the boats worked separately to protect ships in a harbor and the new routing system now allows them to swarm as a team to surround and neutralize threats.… Read More

How Skyscrapers Are Being Built Higher and Higher

How Skyscrapers Are Being Built Higher and Higher

Tall buildings often have tuned mass dampers hidden inside their structures to stabilize them against the wind. Those tuned mass dampers are huge and heavy and help limit a building’s movement by swaying in the opposite direction of the building. That is, if the wind is making a skyscraper sway to the right, the damper will sway to the left to dissipate the kinetic energy, and reduce the, um, swaying. What’s interesting is that the Burj Khalifa, the world’s tallest building, doesn’t have that.
