2024-04-30 IEA “Batteries And Secure Energy Transitions” Report
Quote: “”The IEA’s “Batteries and Secure Energy Transitions” report finds that capital costs for battery storage systems are projected to fall by up to 40 percent by 2030. This significant cost reduction will make combining solar and wind with battery storage more affordable than building new coal or gas power plants in many parts of

2024-04-28 US Plan To Upgrade 100k Miles Of Transmission Lines In 5 Years
Short article about deployment of enhancements such as high performance conductors. Quote: “”…and up to $331 million from the Bipartisan Infrastructure Law for a new 285-mile transmission line that will carry more than 2 gigawatts (GW) of transmission capacity from Idaho to Nevada.”” The US just came up with a plan to upgrade 100k miles

2024-04-20 RCWL-0516 Microwave Doppler Motion Sensor Module Schematic KO4BB
The modules use both the RCWL-9616 and the BISS-0001 but it seems the schematics are all labeled BISS-0001. The parts values are different. He gives some good information about them. They operate at 3.5 and 3.98 GHz – the ones I have were advertised at 5 GHz. Also he shows his own version that uses a

2021-06-14 Electric Vehicles Are In Stealth Mode
I have a PIR (passive infrared) motion sensing light on my porch for more than a year, and I’ve noticed that it can sense some of the cars that go by. If the car has been running, like coming home it will usually trigger the light. But when a neighbor starts the cold car and

2020-05-01 UFO Detector And Sighting!
Photo from ?? Thanks, Mike Guerrucci. This is a simple device. That means it’s just a buzzer and a battery. And it has a super sensitive magnetic switch. This detector is always open until it is disturbed by a magnetic field. They call it a magnetometer. One way to make this is to use a

2020-04-19 Ultrasonic Transceiver Design Idea
Many years ago I saw electronic listening devices for receiving a block of ultrasonic frequencies that bats use and downconvert that block to frequencies that humans can hear. But no one to my knowledge has tried to convert human frequencies up to ultrasonic frequencies so that humans can try to establish a conversation with other
