Harvesting vibrational energy from 'colored noise'

TechXplore

The energy demands of today's ubiquitous small electronic devices—including sensors, data transmitters, medical implants and 'wearable' consumer products such as Fitbits—can no longer be met by chemical batteries alone. This gap can be filled by energy harvesters, which turn ordinary, ambient vibrational energy into electrical energy.

Cooling conjecture: cloud engineering could be more promising than previously believed

Envirotec Magazine

Cloud ‘engineering’ could be more effective for climate cooling than previously thought, because of the increased cloud cover produced, new research seems to show. In a study published in Nature Geoscience , researchers found that marine cloud brightening (MCB), also known as marine cloud engineering, works primarily by increasing the amount of cloud cover, accounting for 60-90% of the cooling effect.

Water-based paints may create less of a stink, but some still contain chemicals flagged as potentially hazardous, according to new research. Water-based paints have emerged as “greener” and less smelly than solvent-based options. And they are often advertised as containing little-to-no VOCs. But a new study of these paints shows many of them do contain compounds that are considered VOCs, along with other chemicals of emerging concern.
