The US has a huge amount of land with a very good supply of wind, and this has been developed with a large amount of WTs – wind turbines. Iowa has a lot of WTs, but Texas is the WT leader by far, with over 30 Gigawatts of installed WTs. Installing WTs is relatively easy

This is an interesting article: mainly about a miniature Tuneable YIG – yttrium-iron-garnet – filter that could replace many fixed filters. Quote “”Wireless devices use different filters for different frequencies, with the effect that covering all frequencies or bands requires large numbers of filters that take up substantial space. (The typical smartphone includes upwards of

Quote: “”Renewables are nearly 30% of utility scale generating capacity. The latest capacity additions have brought solar’s share of total available installed utility-scale (i.e., >1 MW) generating capacity up to 8.25%, surpassing that of hydropower (7.88%). Wind is currently at 11.77%. Solar and wind combined now account for more than a fifth (20.02%) of the US’s

We should get rid of all insecticides. Use a simple autonomous bug zapper that works around the clock. https://www.theguardian.com/environment/article/2024/may/18/sticky-trick-new-glue-spray-kills-plant-pests-without-chemicals?utm_term=6648531fa6032e6372afbf52d4456d8a&utm_campaign=SaturdayEdition&utm_source=esp&utm_medium=Email&CMP=saturdayedition_email
This circuit is used for converting an analog signal into a digital pulse stream. Such things as class D audio amplifiers, servo amplifiers, A to D converters, or sending an analog signal across a fiber optic link. The Schematic and explanation here in this webpage. https://lrak.net/wiki/555_Delta-Sigma_Modulator.html The output signal is shown as audio modulated onto

Good article a few months old. JHAT recently had this reconductoring topic. This article also describes the Heimdall Ball temperature monitoring. One thing that has not been talked about is the use of BESS – battery energy storage systems – to reduce the peak load on the transmission lines. That’s what they did in Australia

This link to the article is supposed to be free, and *not* behind a paywall. This well-researched article is a good article, with some statements that are disputable. One example is that they state that lithium batteries are flammable. The LFP cells now used in battery storage systems are low to not flammable. There are

It looks like this supercapacitor could quickly charge and discharge, thus reducing the cycles on the EV battery. https://www.livescience.com/technology/electronics/ev-batteries-could-last-much-longer-thanks-to-new-capacitor-with-19-times-power-density-that-scientists-created-by-mistake
