2024-06-04 Gallium Nitride MOSFETs To Revolutionize Power Electronics
Gallium nitride power electronics will replace silicon and will make laptop power adapters smaller than a golf ball and will save major amounts of electricity. GaN devices will waste a lot less power, which will enable power electronics equipment to be made smaller and more efficient. Quote: “”GaN-based power electronics, on the other hand, could

2024-06-03 LDES Increasingly Competitive But Unlikely To Match Li-ion’s Cost Reductions
The cost of Lithium-ion batteries is still dropping and sodium-ion batteries use even lower cost materials, so it’s likely that the long duration energy storage – LDES – will not catch up for some time. One LDES is green hydrogen, and hydrogen LDES systems seem to have stagnated, partly due to the falling prices of

2024-06-02 LDES Long Duration Energy Storage Poised To Outcompete Lithium-ion Batteries
This article has some good information. The author stated that China is far ahead in long duration energy storage systems. LDES poised to outcompete lithium-ion batteries
2024-05-26 EVs Are One Step Closer To Becoming Roaming Grid Batteries
This is a good article, it gives the standard numbers like SAE J3068/2, and talks about the limitations of the classes of chargers.
2024-06-01 Trump Fanatics Trying To Doxx Jurors, Threatening War
In this video from BTC and Marc Elias, Brian gets down to the bare truth about Trump: that this lying loudmouthed lowlife refuses to show any contrition for the 34 crimes he has been found guilty of. Trump’s contemptuous behavior towards the judicial system will hopefully negatively affect the sentence that judge Merchan hands down.
