2024-03-12 Keeping The Grid In Balance

At the end he said “… keeping the grid in balance with millions of tons of spinning inertia.”  Well, this is now being simulated by the electronics in the battery energy storage systems and other electronics.  It’s called VMM – virtual machine mode.

Soon, there will be very few thermal power plants left after all the fossil fuel burning power plants have been shut down.  There may be turbines in dams and some thermal power plants, mainly nuclear and some geothermal power plants.  The wind turbines have “spinning inertia” but it’s not easily controlled since sometimes the variable wind may not be blowing.  So I don’t think that wind turbines are considered spinning inertia to the grid.  They are most likely matched to the grid by a MPP controller.

2024-03-11 Flexible LED Filaments

Some information on what current and resistors to use.  The LEDs are all in parallel and need about 3 Volts, current limited with a resistor.

2024-03-11 MethaneSAT Launched, Will Remotely Sense Methane Leaks

Thousands of abandoned oil wells leak methane and no companies will take responsibility.

“”MethaneSAT has officially launched! Circling the Earth 15 times a day, this satellite will detect invisible methane leaks and enable emission reduction from the oil & gas industry.””

2024-03-09 Big Clive’s Old Tungsten Roadwork Beacon – Barricade Flasher

I built this “tungsten roadwork beacon” as Clive calls it, using the parts given in my schematic (photo below).

I didn’t have a 6V, 90 mA lamp, so I simulated it by using three 20 ohm, 1/4 Watt resistors in series, which gives 60 ohms and 100 mA load with 6VDC.  For an indicator I put a blue LED with its 1k series current limiting resistor across the 60 ohm load. 

The “tungsten” incandescent lamp has very low resistance, about 1/10, when cold, so it draws ten times as much current when it is first turned on.  So this lamp can draw as much as 1 amp when first turned on.  The BC548 NPN transistor is a poor choice for the lamp driver because it can only handle 100 to 200 milliamps.   Anything more exceeds its maximum ratings.  So I used a PN2222A which can handle 800 mA.
