It's a fundamental principle of physics that when you use energy, say to run an electric car, some of it is lost. Companies have tried to overcome this by installing hardware that harvests this lost heat, most famously in regenerative braking. Goodyear is hoping to do a similar thing with tyres, d...

For the most part, portable energy generators are intended for modest uses. They can charge your phone, but they won't drive high-powered laptops or small appliances. That might change if Omni3D gets its crowdfunded AirEnergy 3D off the ground. The 3D-printed wind turbine should fit into a backpac...

Forget lab-made materials like graphene -- natural, old-fashioned hemp may be the ticket to our energy future. Researchers have demonstrated that you can make very efficient carbon electrodes simply by heating hemp bast fibers in a two-stage process. The resulting substance holds as much energy as...
