State-driven emissions controls only slightly more expensive

Sometimes, doing things close to home may be more feasible than doing them on a grand scale, even if they cost a bit more. This may be the case for controlling carbon emissions, according to a team of researchers who looked ...

Woven nanotube fibers turn heat into power

Invisibly small carbon nanotubes aligned as fibers and sewn into fabrics become a thermoelectric generator that can turn heat from the sun or other sources into energy.

Near-field routing of hyperbolic metamaterials

Near-field light is invisible light at the subwavelength scale. Harnessed for a variety of practical applications, such as wireless power transfer, near-field light has an increasingly significant role in the development ...

Professor works to maximize efficiency of solar light pipes

If you have witnessed the rainbow pattern that dances on the surface of a CD or DVD, then you have seen diffraction at work. The disk acts as a diffraction grating, an optical element that disperses light into various colors ...

Energy agency: End new fossil fuel supply investments

The International Energy Agency says immediate action is needed to reshape the world's energy sector in order to meet ambitious climate goals by 2050, including ending investments in new coal mines, oil and gas wells.

New optical hydrogen sensors eliminate risk of sparking

Hydrogen as a clean, renewable alternative to fossil fuels is part of a sustainable-energy future, and very much already here. However, lingering concerns about flammability have limited widespread use of hydrogen as a power ...
