Researchers create lithium-air battery that could be 10x more powerful than lithium-ion

Posted by in categories: chemistry, electronics, mobile phones, solar power, sustainability, transportation

A new lithium-air battery created by researchers at the University of Cambridge points the way to the ultimate battery packs of the future, its makers say. With a very high energy density, more than 90 percent efficiency and the capability for more than 2,000 recharge cycles, the new test battery could prove an important stepping stone in the development of this essential technology.

If you’re getting tired of announcements about breakthroughs in battery technology, that’s understandable: as they’re so essential to modern life, many teams of scientists are busy working on the problem around the clock, but it’s an incredibly complex area of chemistry. Any new battery has to improve on what we already have, be safe to use in consumer gadgets, and be commercially viable enough to be affordable for manufacturers.

Those are difficult targets to hit, and that’s why many ‘miracle’ batteries have since fallen by the wayside – once the initial lab work is done, proving concepts and scaling up production is very difficult to get right. The potential rewards are huge though, not just for smartphones but for electric cars and solar power, where batteries are essential for storing energy to use when the sun isn’t shining.

Microbiomes could hold keys to improving life

Posted by in categories: biotech/medical, sustainability

Forty-eight scientists from 50 institutions in the U.S. have formed the Unified Microbiome Initiative Consortium (UMIC). The scientists envision a coordinated effort spanning national cross-institutional and cross-governmental agency support with the goal of driving forward cutting-edge microbiome research, enabling breakthrough advances in medicine, ecosystem management, sustainable energy, and production of commodities. Their proposal was published online in the journal Science on Oct. 28.

The Autopilot is learning fast: Model S owners are already reporting that Tesla’s Autopilot is self-improving

Posted by in categories: Elon Musk, neuroscience, robotics/AI, sustainability, transportation

During the press conference for the release of the Autopilot, Tesla CEO Elon Musk referred to each Model S owners as “expert trainers” – meaning that each driver will train the autonomous features of the system to feed the collective network intelligence of the fleet by simply driving the electric vehicle on Autopilot.

He said that the system should improve everyday, but that improvements might only become noticeable every week or so by adding up. Just a few weeks after the release, Model S owners are already taking to the Tesla Motors Club forum to describe how the Autopilot is improving…

Tesla’s Autopilot approved for international use

Posted by in categories: Elon Musk, robotics/AI, sustainability, transportation

At the launch of its latest Autopilot features, Tesla CEO Elon Musk noted that it would roll out the new vehicle capabilities to nations outside the United States once it got regulatory approval. Today Musk tweeted that the company has gotten approval from all those countries (except Japan). Now Tesla owners around the world can enjoy the slightly unnerving feeling of letting their Model S drive itself on the highway. Musk also announced that Autopilot 1.01 would be coming soon with improved fleet learning, better lane tracking on poor roads, curved speed adoption and controller smoothness.

Engineered viruses provide quantum-based enhancement of energy transport

How cool is this!


Rendering of a virus used in the MIT experiments. The light-collecting centers, called chromophores, are in red, and chromophores that just absorbed a photon of light are glowing white. After the virus is modified to adjust the spacing between the chromophores, energy can jump from one set of chromophores to the next faster and more efficiently.

Amazing promises of nuclear fusion: How close are we?

Posted by in categories: nuclear energy, sustainability

“Tens of billions of dollars have been spent in the past 60 years, entire careers have been invested, but the ability to produce a commercially viable nuclear fusion reactor remains undemonstrated.”


For 60 years the world’s been waiting for cheap, clean, safe, sustainable power from nuclear fusion. Are we there yet?

How Tesla is ushering in the age of the learning car

Posted by in categories: Elon Musk, information science, robotics/AI, sustainability, transportation

Tesla’s new autopilot system is relying on the cutting edge of machine learning, connectivity and mapping data.

While Tesla’s new hands-free driving is drawing a lot of interest this week, it’s the technology behind-the-scenes of the company’s newly-enabled autopilot service that should be getting more attention.

At an event on Wednesday Tesla’s CEO Elon Musk explained that the company’s new autopilot service is constantly learning and improving thanks to machine learning algorithms, the car’s wireless connection, and detailed mapping and sensor data that Tesla collects.

“The world is facing some huge problems. There’s a lot of talk about how to solve them. But talk doesn’t reduce pollution, or grow food, or heal the sick. That takes doing. This film is the story about a group of doers, the elegantly simple inventions they have made to change the lives of billions of people, and the unconventional billionaire spearheading the project.”

Researchers use engineered viruses to provide quantum-based enhancement of energy transport

Posted by in categories: bioengineering, genetics, particle physics, quantum physics, solar power, sustainability

Nature has had billions of years to perfect photosynthesis, which directly or indirectly supports virtually all life on Earth. In that time, the process has achieved almost 100 percent efficiency in transporting the energy of sunlight from receptors to reaction centers where it can be harnessed—a performance vastly better than even the best solar cells.

One way plants achieve this efficiency is by making use of the exotic effects of quantum mechanics—effects sometimes known as “quantum weirdness.” These effects, which include the ability of a particle to exist in more than one place at a time, have now been used by engineers at MIT to achieve a significant efficiency boost in a light-harvesting system.

Surprisingly, the MIT researchers achieved this new approach to solar energy not with high-tech materials or microchips—but by using genetically engineered viruses.
