Power stations driven by light

The smallest building blocks within the power stations of organisms which get their energy directly from the sun are basically miniature reactors surrounded by collectors which capture photons and forward them to the center. The close correlation between structure and interaction of the components boosts productivity, a strategy which researchers are using for increasing the efficiency of solar technology. … read more

Was 2018 the Year of the Home Battery?

2018 turned out to be a pretty good year for batteries. Prices continued to fall and a handful of states like New York, Colorado and Florida created new policies to drive adoption from storage mandates to new net metering and interconnection policies, as well as new incentives specifically for energy storage. With more homeowners installing […]

A new way to measure solar panel degradation

How does one inspect solar panels in real time, in a way that is both cost-effective and time-efficient? Researchers have now developed and improved statistical and machine learning-based alternatives to enable real-time inspection of solar panels. Their research found a new application for clustering-based computation, which uses past meteorological data to compute performance ratios and degradation rates. … read more

Great potential for floating solar photovoltaics systems

Researchers estimate that installing floating solar photovoltaics on the more than 24,000 human-made US reservoirs could generate about 10 percent of the nation's annual electricity production. Their findings reveal for the first time the potential for floating PV to produce electricity in the United States. … read more

Strategies to Minimize the Oft-Overlooked Soft Costs of Solar Installations

Despite many people assuming that the bulk of upfront solar power costs come from the manufacture of solar PV panels, soft costs– such as planning and installation labor– actually account for well over half of the average solar system.  Minimizing these soft costs presents great opportunity to increase the access to residential solar and hasten […]

Engineers, zoologists reveal how gulls 'wing morph' for stable soaring

Aviation experts and zoologists have provided new insights into how gulls configure their wing shape -- known as wing morphing -- to stabilize their flight. The findings could be used to design more efficient flying vehicles, including soaring drones for farming or environmental monitoring.read more

Understanding dynamic stall at high speeds

Although many fixed-wing aircraft can withstand similar rapid pitch-up maneuvers, a vehicle subject to this dynamic stall process is not reliably controllable. Motivated by the lack of detailed understanding, researchers took a deep dive into the physics of dynamic stall so that it can be used beneficially and reliably by aircraft.read more

Assessing the promise of gallium oxide as an ultrawide bandgap semiconductor

In microelectronic devices, the bandgap is a major factor determining the electrical conductivity of the underlying materials, and a more recent class of semiconductors with ultrawide bandgaps are capable of operating at much higher temperatures and powers than conventional small-bandgap silicon-based chips. Researchers now provide a detailed perspective on the properties, capabilities, current limitations and future developments for one of the most promising UWB compounds, gallium oxide. … read more

How plants can generate electricity to power LED light bulbs

Researchers have discovered that living plants are literally 'green' power source: they can generate, by a single leaf, more than 150 Volts, enough to simultaneously power 100 LED light bulbs. Researchers also showed that an 'hybrid tree' made of natural and artificial leaves can act as an innovative 'green' electrical generator converting wind into electricity.read more
