Fuel cells about to power the drone industry

Just as their commercial use begins to spread, fuel-cell technology is improving the way drones are powered

Canadian companies are placing big bets on a better way of powering drones.

So far these stealthy units — long used by military forces for intelligence-gathering, surveillance and striking targets — have been powered by internal combustion engines or lithium polymer batteries.

Nikola Motor: Taking a swipe at ‘Tesla Semi’, announces ‘working prototype’ for December


In a weird and clearly reactionary move after Elon Musk announced that Tesla will venture in the semi-truck business, electric truck startup Nikola Motor, which like Tesla borrowed its company name from Nikola Tesla, announced that it will unveil a working prototype of its first truck, the Nikola One, on December 2nd in Salt Lake City.

New 3D printed graphene super batteries will last a lifetime


Batteries are becoming more and more crucial in our lives every year. From our smartphones to our laptops, and increasingly even our cars, batteries make the world go round. The only problem is that today’s generation of lithium batteries are increasingly incapable of providing energy on a scale that we need – especially when it comes to the charges they hold and the time it takes to recharge them. But there is a solution on the horizon, and it is being made possible by a radical material shift. For scientists from Swinburne University in Melbourne, Australia, have developed a new battery (technically speaking a supercapacitor) made from 3D printed graphene, which can hold a larger charge of energy, is recharged in a matter of seconds and will last a lifetime.
