2023-07-05 Huge Amount Of Renewables Needed To Replace Fossil Fuels
The amounts of renewables needed to replace fossil fuels is huge. Up to 17% of the often estimated 51 gigatons per year of the world’s carbon budget could be used to manufacture PV modules, and that is just for solar – it doesn’t count wind turbines. We must triple, then double that much production to

2023-07-04 The End Of Haber-Bosch – Its Replacement
New research has enabled fixating nitrogen easier than by the Haber-Bosch process. About half the world’s food supply depends on the fertilizer made by the Haber-Bosch process. It is imperative that we end the use of fossil fuels in the Haber-Bosch process because its end product is CO2 greenhouse gas. It must be replaced by

2023-07-01 China: Wind, Solar Growing Like Crazy, But Fossil Fuels, Too
As I said earlier, China already has 1000 GW of renewables and will soon have 1200 GW, approaching 30% of its total generation. That’s enormous – the whole US has 1300 GW generation total! The Chinese are building wind and solar as fast as they can, and are going to meet their promised goals even

I bought this HP 721A power supply from an eBay seller for about $40 total. The old timer (dated 12-15-59) needed some TLC – the line cord jacket was frayed and falling off so I replaced it. It’s all solid state, germanium. The case needs to be cleaned up, but it’s got some signs of

2023-06-17 Replacing a Power BJT With a MOSFET
How to Replace a Transistor (BJT) with a MOSFET Crys Crystii I read that article and he *completely* ignores the gate drive needed to properly switch a power MOSFET on and off. MOSFETs are mosly used for switching high currents, and the time it takes to switch one from nonconducting to conducting *must* be minimized.
