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.
Calculating the cost of EV batteries
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.”
