In this article, we'll look at one interesting vision of the future, General Motor's remarkable concept car, the Hy-wire. GM may never actually sell the Hy-wire to the public, but it is certainly a good illustration of various ways cars might evolve in the near future. Contents Hy-...
Suppose you want to wire up a bank safe so it triggers an alarm whenever the door opens. How would that work in practice? You'd need electrical contacts on both parts of the door frame so when the door opened the circuit would be broken, triggering the alarm. But think how tricky it...
GPS Receiver Basics Like acell phone, aGPS receiverrelies on radio waves. But instead of using towers on the ground, it communicates with satellites that orbit the Earth. There are currently 27 GPS satellites in orbit -- 24 are in active use and 3 act as a backup in case another satellit...
Earthbags could be used as infill for a conventionally framed house, but typically they're more monolithic structures, meaning that the entire structure is made from the same materials throughout. Other than the bags and the barbed wire that holds the bags together, earthbag building is a natur...

A powerful solar flare erupted from Sunspot 486 on Oct. 28, 2003. The flare sent X-rays traveling at the speed of light toward Earth, causing a radio storm in the ionosphere. NASA/WireImage/Getty Images The sun's core starts from the center and extends outward to encompass 25 percent of...
Earth Leakage Circuit Breaker is a protection device used in electrical systems for detecting the leakage currents and interrupting the circuit. In an electrical circuit, the electric current flows from source to the load through the phase wire and from load back to the source through the neutral...
Known as the common wire, (C-Wire) provides WiFi thermostats continuous power from heating (e.g. furnaces) and cooling systems (e.g. Air Conditioning systems). C-Wires are required on all Resideo WiFi thermostats. For full thermostat wiring assistance: Click here. To purchase a c-wire ...
Earth's Magnetic Field A diagram of Earth's Magnetic Field The reason why a compass works is more interesting. It turns out that you can think of the Earth as having a gigantic bar magnet buried inside. In order for the north end of the compass to point toward theNorth Pole, you have...
What Are the Advantages of Wire Transfers? Wire transfers allow for the individualized transmission of funds from individuals or entities to others while still maintaining the efficiencies associated with the fast and secure movement of money. The sender can initiate a wire transfer quickly and the ...
