Year 2021 viable fusion reactor in a z pinch device which is compact enough to fit in a van or airplane ✈️ 😀

The fusion Z-pinch experiment (FuZE) is a sheared-flow stabilized Z-pinch designed to study the effects of flow stabilization on deuterium plasmas with densities and temperatures high enough to drive nuclear fusion reactions. Results from FuZE show high pinch currents and neutron emission durations thousands of times longer than instability growth times. While these results are consistent with thermonuclear neutron emission, energetically resolved neutron measurements are a stronger constraint on the origin of the fusion production. This stems from the strong anisotropy in energy created in beam-target fusion, compared to the relatively isotropic emission in thermonuclear fusion. In dense Z-pinch plasmas, a potential and undesirable cause of beam-target fusion reactions is the presence of fast-growing, “sausage” instabilities. This work introduces a new method for characterizing beam instabilities by recording individual neutron interactions in plastic scintillator detectors positioned at two different angles around the device chamber. Histograms of the pulse-integral spectra from the two locations are compared using detailed Monte Carlo simulations. These models infer the deuteron beam energy based on differences in the measured neutron spectra at the two angles, thereby discriminating beam-target from thermonuclear production. An analysis of neutron emission profiles from FuZE precludes the presence of deuteron beams with energies greater than 4.65 keV with a statistical uncertainty of 4.15 keV and a systematic uncertainty of 0.53 keV. This analysis demonstrates that axial, beam-target fusion reactions are not the dominant source of neutron emission from FuZE. These data are promising for scaling FuZE up to fusion reactor conditions.

Most of us underestimate how quickly electric vehicles (EVs) will take over the car market. It’s mostly down to the plummeting cost of batteries. They have only become cost-competitive in the last few years and have fallen in price 98% since the 1990s. (99% if you include inflation.)

This gave me a combined series of the unit cost of lithium-ion batteries from 1991 to 2022 in $2022. I’ve plotted it as a chart here. And here is the logarithmic version.

As gasoline continues to lose its cachet as a reliable energy source, auto manufacturers have started to turn toward cleaner-burning fuels. However, they’re still trying to figure out how to use the cleanest fuel of all — the air we breathe.

Illinois Institute of Technology Assistant Professor of Chemical Engineering Mohammad Asadi has developed solutions to two major problems facing lithium-air batteries. Lithium-air batteries hold more energy in a smaller battery size than their more common counterpart, the lithium-ion battery, but until now, lithium-air batteries have been overlooked in commercial applications because lithium-air batteries tended to die after fewer recharges and require a lot more energy to charge than can be generated by the battery later.

After almost a decade working in the oil and gas industry, Asadi turned his focus to carbon dioxide in the atmosphere, particularly caused by the transportation industry, which consumes around 38 to 40 percent of the world’s energy. “With more widespread use of electric vehicles, you can drastically reduce transportation-based carbon emissions,” says Asadi. “But to put more electric vehicles on the road, we’ll need batteries—lots of them.”

Continental has won the innovation award at CES 2023 for the seventh consecutive year.

Continental AG, the German developer of pioneering technologies in mobility, has been picked to receive the Innovation Award for its Scenic View Heads-Up Display (HUD) at CES 2023, the company said in a press release. The CES is a technology trade show held in Las Vegas in January every year.

The new concept car will be “electric, circular, and digital.”

The future BMW plan calls for a large number of new electric vehicles. The company already has a strong portfolio of electric vehicles, but its new platform will only be focused on electrification.

BMW CFO Dr. Nicolas Peter previously announced at the end of the Q3 2022 quarterly report that BMW will unveil a new Vision Car at the upcoming CES 2023. “The next highlight on our way to the Neue Klasse will follow in January 2023. At the CES in Las Vegas, we will be presenting a visionary vehicle that will underpin our digital expertise. The future of the BMW Group is electric, circular, and digital,” Peter said.

Like so many on-screen action heroes, she was elbowed aside when newer stars appeared and started grabbing more viewers with bigger weapons, better special effects and more elaborate adventures.

That’s when Lars Wingefors spied an opportunity and swooped in.

Earlier this year, the little-known Swedish billionaire bought the rights to British archaeologist Lara Croft and the vehicle that turned her into a household name. After debuting 26 years ago, “Tomb Raider” went on to become one of the best-selling video game franchises of all time, spawning lucrative spinoffs and movies starring Angelina Jolie and Alicia Vikander, before faltering as bigger games and mobile apps appeared and gaming moved away from its core teenage male audience to young girls, college students and families.
