Hanergy’s solar-powered electric cars can charge themselves while driving

Posted by in categories: solar power, sustainability, transportation

In just a few years, we could see an electric car on the market that doesn’t need a charging station to ‘fuel up.’

The biggest apparent stumbling blocks for electric vehicles (EVs) seems to be their range — the distance that can be driven between charging — and the time it takes for an EV battery to be charged. When competing against gas cars, which can be filled up in just a few minutes, and can cover a range of several hundred miles per tank, the idea of having a limited range and a longer ‘fueling’ time with an EV isn’t one that most of us are comfortable with. And when considering the easy availability of fuel from the vast number of gas stations (as opposed to the EV charging stations that are few and far between in most areas), switching from gas to electric mobility is a bit of a stretch for many people (not even taking into account the higher cost for EVs).

However, as costs go down, and as EV ranges increase (along with the growing numbers of dedicated EV charging stations), electric transport options will start to become more and more desirable (especially in times of rising gas prices), but will still most likely need to be tethered to charging points, unless the next generation of electric cars follows in the footsteps of one Chinese company.

Discovery could dramatically boost efficiency of perovskite solar cells

Posted by in categories: nanotechnology, solar power, sustainability

Scientists from the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have discovered a possible secret to dramatically boosting the efficiency of perovskite solar cells hidden in the nanoscale peaks and valleys of the crystalline material.

Solar cells made from compounds that have the crystal structure of the mineral perovskite have captured scientists’ imaginations. They’re inexpensive and easy to fabricate, like organic solar cells. Even more intriguing, the efficiency at which perovskite solar cells convert photons to electricity has increased more rapidly than any other material to date, starting at three percent in 2009 — when researchers first began exploring the material’s photovoltaic capabilities — to 22 percent today. This is in the ballpark of the efficiency of silicon solar cells.

Now, as reported online July 4, 2016 in the journal Nature Energy, a team of scientists from the Molecular Foundry and the Joint Center for Artificial Photosynthesis, both at Berkeley Lab, found a surprising characteristic of a perovskite solar cell that could be exploited for even higher efficiencies, possibly up to 31 percent.

Research may lead to more durable electronic devices such as cellphones

Posted by in categories: bioengineering, computing, solar power, sustainability

Deep inside the electronic devices that proliferate in our world, from cell phones to solar cells, layer upon layer of almost unimaginably small transistors and delicate circuitry shuttle all-important electrons back and forth.

It is now possible to cram 6 million or more transistors into a single layer of these chips. Designers include layers of glassy between the electronics to insulate and protect these delicate components against the continual push and pull of heating and cooling that often causes them to fail.

A paper published today in the journal Nature Materials reshapes our understanding of the materials in those important protective layers. In the study, Stanford’s Reinhold Dauskardt, a professor of materials science and engineering, and doctoral candidate Joseph Burg reveal that those respond very differently to compression than they do to the tension of bending and stretching. The findings overturn conventional understanding and could have a lasting impact on the structure and reliability of the myriad devices that people depend upon every day.

The top 10 emerging technologies of 2016

Posted by in categories: economics, solar power, sustainability

(credit: WEF)

The World Economic Forum’s annual list of this year’s breakthrough technologies, published today, includes “socially aware” openAI, grid-scale energy storage, perovskite solar cells, and other technologies with the potential to “transform industries, improve lives, and safeguard the planet.” The WEF’s specific interest is to “close gaps in investment and regulation.”

“Horizon scanning for emerging technologies is crucial to staying abreast of developments that can radically transform our world, enabling timely expert analysis in preparation for these disruptors. The global community needs to come together and agree on common principles if our society is to reap the benefits and hedge the risks of these technologies,” said Bernard Meyerson, PhD, Chief Innovation Officer of IBM and Chair of the WEF’s Meta-Council on Emerging Technologies.

The list also provides an opportunity to debate human, societal, economic or environmental risks and concerns that the technologies may pose — prior to widespread adoption.

Solar Impulse 2 completes world’s first solar-powered Atlantic flight

Posted by in categories: solar power, sustainability

The flights take such a long time because Solar Impulse 2, as the name suggests, is completely powered by sunlight. The plane’s massive 72-metre wings (broader than a 747!) are covered in some 269.5 square metres of photovoltaic cells. During the day, the cells power four 14kW (17.4hp) electric motors and top-up four 41kWh lithium-ion batteries. During the evening, the motors are driven by the batteries. Max cruise speed when the sun is up is 49 knots (90km/h), and a rather languid 33 knots (60km/h) at night.

The solar cells don’t quite refill the batteries during the day, which means the plane can’t fly forever just yet. Max flight duration is somewhere around five to six days.

For power-saving reasons, the Solar Impulse 2 cockpit can only carry a single human, and is both unheated and unpressurised. The pilots do sleep while they’re up in the air, but usually just for 20 minutes at a time (the telemetry data for one flight showed 10 catnaps of 20 minutes over a 24-hour period). Now multiply those conditions by a continuous flight time of three or four days and you have some idea of the rigours that Piccard and Borschberg must go through.

Using Enzymes to Enhance LEDs

Posted by in categories: computing, engineering, particle physics, quantum physics, solar power, sustainability

Robert Dunleavy had just started his sophomore year at Lehigh University when he decided he wanted to take part in a research project. He sent an email to Bryan Berger, an assistant professor of chemical and biomolecular engineering, who invited Dunleavy to his lab.

Berger and his colleagues were conducting experiments on tiny semiconductor particles called quantum dots. The optical and electronic properties of QDs make them useful in lasers, light-emitting diodes (LEDs), medical imaging, solar cells, and other applications.

Dunleavy joined Berger’s group and began working with cadmium sulfide (CdS), one of the compounds from which QDs are fabricated. The group’s goal was to find a better way of producing CdS quantum dots, which are currently made with toxic chemicals in an expensive process that requires high pressure and temperature.
