HOW TO MAKE a PORTABLE WIND TURBINE: Generally when I want to get away from the city and camp, I take some kind of power source with me. Within my preferences are the Power Banks. With a small and light one, of approximately 40 Watt hours (Wh), I can cha
So how does all of this come together in your home? Let's find out. Circuit Breaker: At Work in Your Home This diagram shows the basic parts and design of a circuit breaker. HowStuffWorks The power distribution grid delivers electricity from a power plant to your house. Inside your hou...
Wind Turbine Power Curve:Every wind turbine has its own power curve. The power curve reflects the power output for every wind speed data point. In the power curve, the cut-in speed is reflected. This is the wind speed at which the turbine will start t...
A final aspect we should consider within the circular economy: How does design change? How does our work at the downstream end of plastic reclamation, turning waste into something new, and figuring out how we collect things, teach us about the upstream changes we can make? How does messing ...
useful in a home or business, it comes off the transmission grid and isstepped-downto the distribution grid. This may happen in several phases. The place where the conversion from "transmission" to "distribution" occurs is in apower substation. A power substation typically does two or three ...
But things are not quite what they seem. Steam and coal never did disappear—not exactly. Where does the electricity we use come from? It would be great if it all came fromrenewable energy(wind turbines, solar panels, and so on), but much of it still comes from coal, burned inpower ...
There is a cathode and a pair (or more) of anodes. There is the phosphor-coated screen. There is a conductive coating inside the tube to soak up the electrons that pile up at the screen-end of the tube. However, in this diagram you can see no way to "steer" the beam — the bea...
How Rail Guns WorkBy: William Harris Photo courtesy Sam Barros of PowerLabs Gunpowder has long been the propellant of choice to launch a projectile from a weapon. But the fine gray powder does have three major limitations: Gunpowder must be carried with the projectile, making the entire ...
Why do aircraft take off and land into the wind? What is the cause of atmospheric pressure? Why does air rise at the equator? How do clouds and precipitation in the atmosphere develop? Please describe the structure of a hurricane, and how they work. Include a discussion of how energy is...
Why didn't I just use an automotive alternator on my wind turbine? Automotive alternators need to spin at very high speed to produce useful amounts of power. Most wind turbines don't spin fast enough for them to work. Update: Here is a video of the wind turbine in operation. Update:...
