Is Tesla’s Elon Musk Making Good On Prediction That Capacitors ‘Supersede’ Batteries?

Posted by in categories: Elon Musk, energy, sustainability, transportation

If I were to make a prediction, I’d think there’s a good chance that it is not batteries. But capacitors.”

Today he may be making good on his prediction. The electric vehicle manufacturer confirmed that it has acquired a small San Diego lab that owns ultracapacitor patents and technology.

Maxwell Technologies provides dry electrode manufacturing technology that can be used to make to make batteries that power electric vehicles and renewable energy systems. The company announced that in an all-stock transaction it will merge and become a wholly owned by a subsidiary of Tesla.

Scientists reveal true shape of Milky Way: It’s warped & twisted

Posted by in categories: energy, mapping, space

It’s even more fascinating than we thought.


The Milky Way looks nothing like the flat space pancake it is usually depicted as. The newly-created and most accurate 3D map of our galaxy reveals that it’s warped and twisted, and even more fascinating.

A group of astronomers from Australia and China have built their “intuitive and accurate three-dimensional picture” by mapping the so-called “classical Cepheids.”

Mollusk with magnetic teeth could be the key to nanoscale energy sources

Posted by in categories: bioengineering, energy, genetics, nanotechnology

A team of scientists have made a new discovery about naturally occurring magnetic materials, which in turn could lead to the development of nanoscale energy sources used to power next generation electronic devices. Researchers from Japan’s Okayama University and UC Riverside’s Bourns College of Engineering worked together to study the gumboot chiton, a type of mollusk that produces teeth made of the magnetic mineral magnetite, in hopes of better understanding its genetic process.

“Sun in a Box”: A New Way to Store Renewable Energy for the Grid

Posted by in categories: energy, sustainability

The new design stores heat generated by excess electricity from solar or wind power in large tanks of white-hot molten silicon, and then converts the light from the glowing metal back into electricity when it’s needed. The researchers estimate that such a system would be much more affordable than lithium-ion batteries, which have been proposed as a viable, though expensive, method to store renewable energy. They also estimate that the system would cost about half as much as pumped hydroelectric storage—the cheapest form of grid-scale energy storage so far.


Delivering solar- or wind-generated power on demand, the system, which uses molten silicon, should be cheaper than other leading options.

Lamborghini and MIT team up on electric supercar without batteries

Posted by in categories: energy, nanotechnology, transportation

Instead, the body of the Lamborghini Terzo Millennio concept car, made from exotic carbon nanotubes, would be used as a supercapacitor. Supercapacitors store and release energy in a manner different from that employed by batteries. They have certain advantages, but also serious disadvantages.

It could be years, if ever, before scientists from MIT and Lamborghini, which is part of the Volkswagen Group ( VLKAF ), can overcome the downsides. But the effort would be worth it, said Mauricio Reggiani, Lamborghini’s head of research and development.

“At the moment, we are really optimistic,” he said.

‘Recycling’ Energy Seen Saving Companies Money

Posted by in categories: economics, energy, sustainability

A Chicago-based entrepreneur says many industrial power users can save money, get more electricity, and reduce greenhouse gas emissions by using the energy they already consume more efficiently. It’s called recycling energy — capturing waste heat and turning it into power.

Near-infrared metasurface reflects only one direction of circularly polarized light

Posted by in category: energy

Chiral surfaces, which have differing responses for left- and right-handed circularly polarized (LCP and RCP) light, can be useful in optical experimentation. Metamaterials, which can be made into circular polarizers, are promising for creating chiral surfaces. Scientists at the Missouri University of Science and Technology (Rolla, MO) and the Argonne National Laboratory (Argonne, IL) have now created a chiral metamaterial-absorbing surface that has a large circular dichroism (CD) over the 1.3–1.8 μm spectral region. The chiral absorber could be useful for optical filters, thermal energy harvesting, optical communications, and chiral imaging.


A chiral optical metasurface selectively absorbs either left- or right-handed circularly polarized light; it could be useful in imagers and other optical systems.

Scientists analyzed the gamma rays emitted during the NPDGamma Experiment and found parity-violating asymmetry

Posted by in category: energy

Scientists analyzed the gamma rays emitted during the NPDGamma Experiment and found parity-violating asymmetry, which is a specific change in behavior in the force between a neutron and a proton. They measured a 30 parts per billion preference for gamma rays to be emitted antiparallel to the neutron spin when neutrons are captured by protons in liquid hydrogen. After observing that more gammas go down than up, the experiment resolved for the first time a mirror-asymmetric component or handedness of the weak force.
