SpaceX Seeks $656,000 From California in Midst of Musk’s Battle

Posted by in categories: Elon Musk, employment, space travel, sustainability

(Bloomberg) — Elon Musk’s Space Exploration Technologies Corp. is seeking almost $656,000 in new funding from California in the midst of the billionaire’s battle over whether Tesla Inc. should be reopening its plant in the state.

SpaceX’s request for funds to train existing workers and hire new ones will go before the state’s Employment Training Panel on May 15, one week after the county that’s home to Tesla’s factory sought to block the facility from resuming operations. The company sued the next day, and its chief executive officer threatened to move Tesla’s headquarters, future programs and potentially its manufacturing out of the state.

Musk, 48, appears to be prevailing in the stand-off. He tweeted Monday that Tesla was restarting production in spite of Alameda County’s order and said that if anyone is arrested, he wanted to be the only one.

Elon Musk restarts Tesla factory in defiance of county orders

Posted by in categories: Elon Musk, sustainability, transportation

Tesla CEO Elon Musk said Monday that the company’s factory in Fremont, California is open and has restarted production despite a stay-at-home order issued by Alameda County.

Musk said in tweet Monday afternoon that he will “be on the line,” a reference to the assembly line at the factory where Tesla makes the Model X, Model S, Model 3 and Model Y. He added “if anyone is arrested, I ask that it only be me.”

Tesla is restarting production today against Alameda County rules. I will be on the line with everyone else. If anyone is arrested, I ask that it only be me.

China To Introduce EV Wireless Charging Standard Based On WiTricity Technology

The China Electricity Council (CEC) ratified and published a set of national standards for electric vehicle wireless charging, which will be based on the magnetic resonance technology developed and patented by WiTricity, a wireless power transfer specialist based in Massachusetts.

Lack of standardization was always a major obstacle for the popularization of the wireless charging, but it seems that in the near future the industry will finally introduce a general solution for all EVs — not only in China, but also globally.

In a potential big win for renewable energy, Form Energy gets its first grid-scale battery installation

Posted by in categories: energy, sustainability

Form Energy, which is developing what it calls ultra-low-cost, long-duration energy storage for the grid, has signed a contract with the Minnesota-based Great River Energy to develop a 1 megawatt, 150 megawatt hour pilot project.

The second-largest electric utility in the Minnesota, Great River Energy’s installation in Cambridge, Minn. will be the first commercial deployment of the venture-backed battery technology developer’s long-duration energy storage technology.

From Energy’s battery system is significant for its ability to deliver 1 megawatt of power for 150 hours — a huge leap over the lithium ion batteries currently in use for most grid-scale storage projects. Those battery systems can last for two- to four-hours.

Engineers Unveil a System That Delivers Electricity Wirelessly

Posted by in categories: mobile phones, robotics/AI, sustainability, transportation

Wireless charging is already a thing (in smartphones, for example), but scientists are working on the next level of this technology that could deliver power over greater distances and to moving objects, such as cars.

Imagine cruising down the road while your electric vehicle gets charged, or having a robot that doesn’t lose battery life while it moves around a factory floor. That’s the sort of potential behind the newly developed technology from a team at Stanford University.

If you’re a long-time ScienceAlert reader, you may remember the same researchers first debuted the technology back in 2017. Now it’s been made more efficient, more powerful, and more practical – so it can hopefully soon be moved out of the lab.

Toward artificial photosynthesis

Posted by in categories: solar power, sustainability

The creation of a fully artificial living cell would signify progress in both understanding current life and the development of synthetic organisms. A crucial component of any living organism is energy generation: the means to power its internal machinery. Because of their relative simplicity, catabolic reactions are the classical means for providing carbon and energy to synthetic cells, and much work has been done in optimizing which energy substrates work best for particular reactions ([ 1 ][1]). Despite robust success using small-molecule energy sources, the possibility of designing anabolic mechanisms that can harvest virtually limitless energy from light is very alluring yet remains unrealized.

Simple method for measuring the state of lithium-ion batteries

Posted by in categories: computing, mobile phones, particle physics, sustainability, transportation

Rechargeable batteries are at the heart of many new technologies involving, for example, the increased use of renewable energies. More specifically, they are employed to power electric vehicles, cell phones, and laptops. Scientists at Johannes Gutenberg University Mainz (JGU) and the Helmholtz Institute Mainz (HIM) in Germany have now presented a non-contact method for detecting the state of charge and any defects in lithium-ion batteries. For this purpose, atomic magnetometers are used to measure the magnetic field around battery cells. Professor Dmitry Budker and his team usually use atomic magnetometry to explore fundamental questions of physics, such as the search for new particles. Magnetometry is the term used to describe the measurement of magnetic fields. One simple example of its application is the compass, which the Earth’s magnetic field causes to point north.

Non-contact quality assurance of batteries using atomic magnetometers

The demand for high-capacity is growing and so is the need for a form of sensitive, accurate diagnostic technology for determining the state of a battery cell. The success of many new developments will depend on whether batteries can be produced that can deliver sufficient capacity and a long effective life span. “Undertaking the quality assurance of rechargeable batteries is a significant challenge. Non-contact methods can potentially provide fresh stimulus for improvement in batteries,” said Dr. Arne Wickenbrock, a member of Professor Dmitry Budker’s work group at the JGU Institute of Physics and the Helmholtz Institute Mainz. The group has achieved a breakthrough by using atomic magnetometers to take measurements. The idea came about during a teleconference between Budker and his colleague Professor Alexej Jerschow of New York University. They developed a concept and, with close cooperation between the two groups, carried out the related experiments in Mainz.
