Quantum computers show potential to revolutionize chemistry

Posted by in categories: chemistry, neuroscience, quantum physics, robotics/AI, solar power, supercomputing, sustainability

Like this feature on QC.


If you have trouble wrapping your mind around quantum physics, don’t worry — it’s even hard for supercomputers. The solution, according to researchers from Google, Harvard, Lawrence Berkeley National Laboratories and others? Why, use a quantum computer, of course. The team accurately predicted chemical reaction rates using a supercooled quantum circuit, a result that could lead to improved solar cells, batteries, flexible electronics and much more.

Chemical reactions are inherently quantum themselves — the team actually used a quote from Richard Feynman saying “nature isn’t classical, dammit.” The problem is that “molecular systems form highly entangled quantum superposition states, which require many classical computing resources in order to represent sufficiently high precision,” according to the Google Research blog. Computing the lowest energy state for propane, a relatively simple molecule, takes around ten days, for instance. That figure is required in order to get the reaction rate.

‘Green’ electronic materials produced with synthetic biology

Posted by in categories: bioengineering, biotech/medical, computing, nanotechnology, solar power, sustainability

Biowire.


Researchers led by microbiologist Derek Lovely say the wires, which rival the thinnest wires known to man, are produced from renewable, inexpensive feedstocks and avoid the harsh chemical processes typically used to produce nanoelectronic materials.

Lovley says, “New sources of electronic materials are needed to meet the increasing demand for making smaller, more powerful electronic devices in a sustainable way.” The ability to mass-produce such thin conductive wires with this sustainable technology has many potential applications in electronic devices, functioning not only as wires, but also transistors and capacitors. Proposed applications include biocompatible sensors, computing devices, and as components of solar panels.

Hanergy claims solar cars need 5 hours of sun for 50 miles of range

Posted by 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

“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 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 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.
