2024-03-16 Climate Crisis Is A Health Risk Everywhere

This interview tells us that people are already having to adapt to climate change.  It’s already happening.

Quote “”Most actions to tackle climate change directly are also very sensible health-protecting measures, so people should try to adopt these. These include choosing healthier diets, with less meat and more plants, or choosing to walk more.””

2024-03-16 US Hydrogen Industry Kicks Into High Gear

This article is mostly about Plug Power, which they call a startup.  They talk about the the BIL – Bipartisan Infrastructure Law and its funding incentives.

2024-03-15 Decoupled Supercapacitive Electrolyzer For Membrane-free Water Splitting

The above is the title of the research paper.   The article below is some 3rd or 4th party news source.

This electrolyzer uses a single electrode to produce both the hydrogen and oxygen, depending on polarity.  They claim that this reduces the chance that hydrogen and oxygen might mix and make an explosive mixture.  But if the electrode makes both, depending on the time, it seems to me that some small amount of mixing is inevitable.  There must be some way of cleaning all the remaining bubbles off the electrode before the switch is made.

2024-03-15 Ferranti Argus “Hearing Aid” Computer

In the “Original Series” chapter this very interesting Wikipedia article talks about the “hearing aid computer” that used the OC-71 germanium transistors which were used in hearing aids and could go only up to 25kHz clock rate. That was quite slow – tube computers could clock at 500kHz.  Later models used faster transistors and could handle 500kHz.  Then later, silicon transistors were even faster.

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.
