Germany calls for a ban on combustion engine cars by 2030
Posted by Shailesh Prasad in categories: energy, finance, policy, transportation
Germany isnât content with relying on financial incentives to usher in an era of pollution-free cars. The countryâs Bundesrat (federal council) has passed a resolution calling for a ban on new internal combustion engine cars by 2030. From then on, youâd have to buy a zero-emissions vehicle, whether itâs electric or running on a hydrogen fuel cell. This isnât legally binding, but the Bundesrat is asking the European Commission to implement the ban across the European Union⊠and when German regulations tend to shape EU policy, thereâs a chance that might happen.
The council also wants the European Commission to review its taxation policies and their effect on the âstimulation of emission-free mobility.â Just what that means isnât clear. It could involve stronger tax incentives for buying zero-emissions cars, but it could also involve eliminating tax breaks for diesel cars in EU states. Automakers are already worried that tougher emission standards could kill diesels â remove the low cost of ownership and itâd only hasten their demise.
Not that the public would necessarily be worried. Forbes notes that registrations of diesels, still mainstays of the European car market, dropped sharply in numerous EU countries in August. Thereâs a real possibility that Volkswagenâs emission cheating scandal is having a delayed effect on diesel sales. Combine that with larger zero-emissions incentives and the proposed combustion engine ban, and it might not take much for Europeans to go with electric or hydrogen the next time they go car shopping.

Physicists just created the worldâs first time crystal
Posted by Shane Hinshaw in categories: energy, physics
Just last month, physicists made the best case yet for why time crystals â hypothetical structures that have movement without energy â could technically exist as physical objects.
And now, four years after they were first proposed, scientists have managed to add a fourth dimension â the movement of time â to a crystal for the first time, giving it the ability to act as a kind of perpetual âtime-keeperâ.
First proposed by Nobel-Prize winning theoretical physicist Frank Wilczek back in 2012, time crystals are hypothetical structures that appear to have movement even at their lowest energy state, known as a ground state.

D-Wave Systems previews 2000-qubit quantum processor
Posted by Sean Brazell in categories: energy, information science, quantum physics
D-Wave Systems announced Tuesday (Sept. 28, 2016) a new 2000-qubit processor, doubling the number of qubits over the previous-generation D-Wave 2X system. The new system will enable larger problems to be solved and performance improvements of up to 1000 times.
D-Waveâs quantum system runs a quantum-annealing algorithm to find the lowest points in a virtual energy landscape representing a computational problem to be solved. The lowest points in the landscape correspond to optimal or near-optimal solutions to the problem. The increase in qubit count enables larger and more difficult problems to be solved, and the ability to tune the rate of annealing of individual qubits will enhance application performance.

NASA just detected high-energy X-rays in space that donât come from any known source
Posted by Shane Hinshaw in categories: energy, space
A NASA-funded study has solved a longstanding mystery over the origin of X-rays that permeate space in our Solar System, but in doing so, itâs also discovered an entire group of high-energy X-rays that canât be explained.
The research comes from a new analysis of data recorded by NASAâs DXL rocket mission, which took flight in 2012 to settle the question of what creates these low-energy X-ray emissions â called the diffuse soft X-ray background â in our corner of the galaxy.
At the time, there were two central hypotheses. X-ray emissions were known to come from solar wind, but scientists also thought they might originate from whatâs called the Local Hot Bubble â a theorised region of hot gas that envelops our Solar System. But which was correct?

Closing in on high-temperature superconductivity
Posted by Shane Hinshaw in categories: energy, physics, transportation
Realistic hover cars coming to future near you.
The quest to know the mysterious recipe for high-temperature superconductivity, which could enable revolutionary advances in technologies that make or use electricity, just took a big leap forward thanks to new research by an international team of experimental and theoretical physicists.
The research paper appears in the journal Science on Sept. 16, 2016. The research is focused on revealing the mysterious ingredients required for high-temperature superconductivity â the ability of a materialâs electrons to pair up and travel without friction at relatively high temperatures, enabling them to lose no energy â to be super efficient â while conducting electricity.

Kardashev Scale: What Itâll Be Like When We Harness the Power of an Entire Galaxy
Posted by Andreas Matt in categories: energy, space
According to the Kardashev scale, a Type III civilization is a society that has managed to harness (and control) the energy output of a galaxy. Hereâs what that means.
To measure the level of a civilizationâs advancement, the Kardashev scale focuses on the amount of energy that a civilization is able to harness. Obviously, the amount of power available to a civilization is linked to how widespread the civilization is (you canât harness the power of a star if you are confined to your home planet, and you certainly canât harness the power of a galaxy if you canât even get out of your solar system).
