When you put your bread in and see the coils glow red, the coils are producing infrared radiation. The radiation gently dries and chars the surface of the bread. The most common way for a toaster to create the infrared radiation is to use nichrome wire wrapped back and forth across a ...
(See How Air Conditioners Work for a more detailed explanation of this cycle.) Reheater -- This captures and collects heat that the cooling process generates. Compressor cooling coils Reservoir How do all these parts fit together to pull moisture from the air? It's fairly simple, but very ...
There also has to be something to make the electricity flow from one point to another through the conductor. One way to get electricity flowing is to use a generator. Holy Electricity In the late 19th century, electricity truly had a noble or even divine reputation -- to the extent that ...
Make a Solar Water Heater Wind Power to Electricity Author's Note: 5 Ideas for Experiments on Conserving Energy 5: Shower or bath? You need energy to heat water. Therefore, if you can get clean without using so much hot water, you'll save. But which uses more hot water, a bath...
To gain access to the lower section of the refrigerator, remove a service panel held by retaining screws at the back of the unit below the condenser coils. The unit may also have a front access panel below the door. This panel may be held by retaining screws, or it may slip up and ...
At this point, the refrigerant’s temperature is much cooler than the inside ambient temperature of the fridge. The next step is for the refrigerant to flow through the evaporator, which is yet another set of coils. But this time, these coils are located inside the refrigerator instead of ou...
Unlike an ordinary induction charger, a WiTricity charger has a transmitter coil that oscillates at a carefully chosen frequency, sending its power to receiver coils in nearby devices that are tuned so they "resonate" at the same frequency—similar to how radios are tuned, selectively, so they...
When winding the flyback transformer, make sure both wire go the same way. If you are going to attach both of your MOSFET's on one heatsink, Use mica insulators! Or other types of insulators to isolate the MOSFET's tabs from each other, otherwise your ZVS driver won't work. ...
Stepping onto a Pavegen tile just one time releases3-5 joulesof electric charge, which is enough to power a light bulb for a few seconds. These tiles use electromagneticinduction, which is when certain materials release an electric charge when they are compressed. Copper coils and magnets then...
AC induction motors use coils on the rotor, which produces “slip,” (the rotor in the motor is slightly behind the magnetic field created by the stator). Because of this, they can produce max torque (twisting force) through high RPMs (revolutions per minute). ECONOMY:AC synchronous AC syn...
