Video: Solar power from energy-harvesting trees

Scientists at VTT have developed a prototype of a tree that harvests solar energy from its surroundings - whether indoors or outdoors - stores it and turns it into electricity to power small devices such as mobile phones, ...

How ambient energy could power the Internet of things

In the modern world, we are increasingly surrounded by digital sensors, cameras and communications devices sending data cloud-based analysis services. Those devices need power, and designers are finding new ways to draw it ...

Researchers discover new uses for high tech alloy

(Phys.org) -- Materials scientists at the U.S. Department of Energy's Ames Laboratory, Etrema Products, Inc. (EPI), and the Naval Surface Warfare Center Carderock Division have developed new ways to form a high tech metal ...

Energy harvesting goes organic, gets more flexible

Nanogenerators capable of converting mechanical energy into electricity are typically made from metal oxides and lead-based perovskites. But these inorganic materials aren't biocompatible, so the race is on to create natural ...
