Hanergy claims solar cars need 5 hours of sun for 50 miles of range
Posted by Karen Hurst in categories: solar power, sustainability, transportation
Glad that I hadn’t plan to buy one of these cars.
A Chinese company is hoping to bring the solar-powered car to market, showing off four new “zero-charge” EVs that get all their range from the sun.

How the end of the Cold War forced NASA to make its Jupiter spacecraft solar-powered — By Akshat Rathi | Quartz
Posted by Odette Bohr Dienel in categories: solar power, space
“NASA’s Juno spacecraft successfully entered an orbit around Jupiter … July 5 … . What’s even more remarkable is that it will do all this with only four 100-watt bulbs worth of power, which it will capture from the Sun using its huge wings made of nearly 20,000 solar cells. The achievement makes Juno the farthest solar-powered spacecraft from the Sun.”

Hanergy’s solar-powered electric cars can charge themselves while driving
Posted by Klaus Baldauf 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.

Innovative Plastic Material has Ability to Move Spontaneously in Visible Light
Posted by Karen Hurst in categories: solar power, sustainability
It would be interesting to see how this could be used in solar panels that can adjust themselves to capture the best/ high quality sun rays;
Written by AZoM
A team of researchers from Eindhoven University of Technology (TU/e) and Humboldt University in Berlin showcased a thin layer of plastic material in the Nature Communications journal, which has the capacity to move spontaneously under the influence of daylight. The researchers feel that this flexible plastic is appropriate as a self-cleaning surface, for example it can be used in solar cells.

Discovery could dramatically boost efficiency of perovskite solar cells
Posted by Karen Hurst 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.

Rising Applications of Quantum Dots in Healthcare Industry to Drive Global Quantum Dots Market
Posted by Karen Hurst in categories: health, nanotechnology, quantum physics, security, solar power, sustainability
Q-Dot demand in Healthcare is predicted to be high.
http://embedded-computing.com/news/rising-quantum-dots-market/#
Quantum Dots Market is driven by increasing demand for energy efficient displays and lighting solutions, North America accounted for largest quantum dots market share, use of quantum dots in solar cells and VLSI design is expected to open new possibilities for quantum dots market.
Quantum dots are semiconducting nanoparticles that range from 1nm to 10nm diameter in size and demonstrate quantum mechanical properties. The peculiarity of quantum dots is that they have ability to unite their semiconductor properties with those of nanomaterials. In addition, tunable nanocrystal size and superior optical properties have made quantum dots attractive semiconducting material for variety of applications in the field of healthcare, optoelectronics, solar energy, and security among others.
