New way to model molecules
Posted by Karen Hurst in categories: biological, chemistry, computing, encryption, quantum physics, robotics/AI, solar power, sustainability
Magine a future in which hyper-efficient solar panels provide renewable sources of energy, improved water filters quickly remove toxins from drinking water, and the air is scrubbed clean of pollution and greenhouse gases. That could become a reality with the right molecules and materials.
Scientists from Harvard and Google have taken a major step toward making the search for those molecules easier, demonstrating for the first time that a quantum computer could be used to model the electron interactions in a complex molecule. The work is described in a new paper published in the journal Physical Review X by Professor Alán Aspuru-Guzik from the Department of Chemistry and Chemical Biology and several co-authors.
“There are a number of applications that a quantum computer would be useful for: cryptography, machine learning, and certain number-theory problems,” Aspuru-Guzik said. “But one that has always been mentioned, even from the first conceptions of a quantum computer, was to use it to simulate matter. In this case, we use it to simulate chemistry.”

ORNL optimizes formula for cadmium-tellurium solar cells
Posted by Karen Hurst in categories: solar power, sustainability
Nice and Kudos to ORNL.
A team led by Jonathan Poplawsky of the Center for Nanophase Materials Sciences used advanced microscopy techniques to discover efficiency differences of crystalline structures of various mixtures of cadmium, tellurium and selenium. In fact, selenium is an integral part of the formulation that resulted in a world record for solar cell efficiency. The team’s paper is published in Nature Communications.
While some of today’s solar cells use a blend of cadmium and tellurium to convert light into electricity, adding the optimum amount of selenium in the right places could help increase efficiency from the current mark of about 22 percent to levels approaching the theoretical limit of 30–33 percent. The trick is to determine the best ratio of selenium.

Foreign rail firms shunted as ‘Made in China’ mantra gathers pace
Posted by Karen Hurst in categories: energy, government, sustainability
Made in China motto is gaining speed in China.
SHANGHAI Foreign firms say they are struggling to gain access to China’s vast railway market as the country, seeking to transform its domestic industry into an export powerhouse, tightens the bidding criteria on rail tenders.
The complaints echo similar concerns raised in other industries including technology and renewable energy, and highlight what some foreign companies see as an uneven playing field when operating in China.

Tesla acquires sister firm SolarCity for $2.6 billion
Posted by Shailesh Prasad in categories: Elon Musk, solar power, sustainability, transportation
Tesla buys SolarCity.
(Reuters) — SolarCity Corp agreed to be acquired by sister company Tesla Motors Inc in a deal worth $200 million less than the initial offer, sending shares of both companies down in early trading on Monday.
Electric vehicle maker Tesla expects to achieve “significant” cost savings and “dramatic improvements” in manufacturing efficiency as a result of the acquisition of solar panel installer SolarCity, Tesla Chief Executive Officer Elon Musk said on Monday.

Tesla is building an electric minibus based on the Model X
Posted by Andreas Matt in categories: climatology, economics, Elon Musk, energy, robotics/AI, sustainability
Elon Musk has been a busy man lately as he works to transition the world to renewable energy and sustainable transportation with the goal of decarbonizing the global economy to meet the challenge of climate change. To meet that goal, Tesla will need to address “high passenger-density urban transport” – and Musk just confirmed plans to create a fully autonomous electric Minibus using the Model X chassis.

Elon Musk is kicking off an automated low-carbon future with the merger of Tesla and SolarCity
Posted by Klaus Baldauf in categories: Elon Musk, robotics/AI, sustainability, transportation
Elon Musk is today set to merge Tesla Motors and SolarCity, Reuters is reporting, kicking off part two of his master plan to transform our cities and suburbs into environmentally friendly automated wonderlands.
In July Musk wrote of his plan to merge the two companies in a blog post entitled Master Plan, Part Deux, saying it was essential to “create a smoothly integrated and beautiful solar-roof-with-battery product that just works, empowering the individual as their own utility, and then scale that throughout the world.
“We can’t do this well if Tesla and SolarCity are different companies, which is why we need to combine and break down the barriers inherent to being separate companies. Now that Tesla is ready to scale Powerwall and SolarCity is ready to provide highly differentiated solar, the time has come to bring them together.”

Lab 2.0: Will Computers Replace Experimental Science?
Posted by Karen Hurst in categories: chemistry, computing, mobile phones, physics, science, solar power, sustainability
We spend our lives surrounded by hi-tech materials and chemicals that make our batteries, solar cells and mobile phones work. But developing new technologies requires time-consuming, expensive and even dangerous experiments.
Luckily we now have a secret weapon that allows us to save time, money and risk by avoiding some of these experiments: computers.

Artificial Intelligence May Soon Drive Your Car — And Keep You Company at the Same Time
Posted by Aleksandar Vukovic in categories: robotics/AI, sustainability, transportation
Honda said in a press release that the AI will use conversations with the driver and other data it gathers ‘both to perceive the emotions of the driver and to engage in dialogue with the driver based on the vehicle’s own emotions.’ The just-announced partnership works toward application of the ‘emotion engine,’ which is ‘a set of AI technologies developed by cocoro SB Corp., which enable machines to artificially generate their own emotions.’
