Nanoscale heat engine exceeds standard efficiency limit
Switchable material could harness the power of the sun—even when it's not shining
It's an obvious truism, but one that may soon be outdated: The problem with solar power is that sometimes the sun doesn't shine.
Power arm band for wearables harvests body heat
New materials for capturing carbon dioxide from combustion gases
(Phys.org) —Carbon dioxide is both a culprit in global warming and also responsible for keeping the Earth warm enough to support life as we know it. It is odorless and colorless, often represented by a ...

Flexible carbon nanotube circuits made more reliable, power efficient
Engineers would love to create flexible electronic devices, such as e-readers that could be folded to fit into a pocket. One approach they are trying involves designing circuits based on electronic fibers, ...
Nanomolecular origami boxes hold big promise for energy storage
(Phys.org) —If you think your origami skills can't be beat – try this: (1) use the world's thinnest material, (2) make the origami fold and unfold itself, and (3) pack into your miniscule origami box ...
Physicists propose a device to capture energy from Earth's infrared emissions to outer space
(Phys.org) —When the sun sets on a remote desert outpost and solar panels shut down, what energy source will provide power through the night? A battery, perhaps, or an old diesel generator? Perhaps something ...
