Q:Hello,I'm doing a research project that requires me to report on five ethical missteps made by engineers/staff at the Fukushima plant that caused the disaster. I'm having trouble with this research because most of the information i'm finding centers around the earthquake and subsequent tsunami that caused so much damage.Can anyone point me toward any human errors that centered around poor ethical judgement?

If you just google human error fukushima you're going to get (a) a few articles from the summer of 2011; (b) a rash of articles from July, 2012; (c) a rash of articles from Oct-Nov, 2013; and (d) a rash of articles from last week (Feb 2014). Whether all will cite ethical missteps is unknown to me.

Q:Hi -- looking for specifically Lister Petter Diesel Generator parts distributor in central Cal. Electrical parts -- cycle timers, a/c disconnects, etc.,. The main company (ListerPetter)is closed until after the 5th, and this machine powers my home, in the process of battery conversion project, and looking to finish this project between th holidays. THis is my hubbys endeavor -- I am just the messenger -- so I hope these questions make sense, please feel free to email me more details or anyhelp you think useful. Thanks everyone

Depending on where you live try the on line yellow pages. Especially in large farming areas, like Fresno or Bakersfield, Stockton etc. Their will be equipment parts shops that will help you find what you need if they do not have it.

Q:has there been any long term tests on the effects on the engine from running it on hydrogen produced from a hydrogen generator and your ordinary gasoline/Diesel?also has anyone attempted to hook a hydrogen/H2O/Brown's gas generator up to a actual diesel generator like wisperwatt or any kind of diesel generator?any help would be great thanks!

Q:I need a flowchart of the endergy conversions while popping popcorn. Example: Chemical energy to physical energy to nuclear energy, etc.

Starting from the pop and moving towards the energy source The kinetic energy of the popped kernel converting to heat when the kernel comes to rest. The kinetic energy of the kernel from the explosion due to steam and the steam escapes with kinetic and heat energy that transfers to the ambient air as the steam condenses and then the droplets fall and convert kinetic energy to heat. Potential energy in the steam as it builds pressure inside the kernel The transfer of heat from the burner into the popping vessel to raise the temperature of the moisture inside the kernel to make steam Where did the energy come from to heat the burner? I will assume it is electrical energy created from a diesel generator peaker plant nearby There is resistance in the burner heating element that converts the electric current to heat. There is also resistance in the wires and transmission lines and transformers that carry the electricity from the power plant to the burner, which is all lost to heat. The electricity is created from a generator where there is an wire-wound aperture spinning in the presence of a magnetic field. The kinetic energy of the aperture gets converted to the electrical energy and sent out on the transmission lines. The kinetic energy of the aperture is created inside a diesel engine by connecting it to the crank shaft - some friction losses due to bearing surfaces. The kinetic energy of the crank shaft is created from an explosion inside a piston. The explosion creates an expansion of gases that push the piston, which spins the crank shaft. Some of this energy is lost to heat dissipatin and friction. The explosion was from the conversion of the chemical energy in the diesel fuel to heat. The pressure in the piston caused the fuel and oxygen mixture to explode. How's that? j

Q:I have bought an ex hire Pike trafic signal trailer which contains a diesel generator. it looks very similar to this (

You would simply use a step-up transformer capable of handling 240V and about 8A. The transformer would be a transformer with 2 secondary windings for every 1 primary winding. This will double the voltage from the primary. 1000W is 1000W no matter what the voltage is. So (in a perfect world), you would get 1000W after stepping the voltage up to 240V. But you would actually get around 80-85% efficiency. But there is always a safety span built into the rating of generators (a 1000W generator could usually put out about 1400W without much of a problem). 1000W 120V * 8.33A (or 110V * 9.1A) 1000W 240V * 4.16A ---Realistically, you should be able to safely draw about 4A @ 240V. Good Luck!

Q:How much carbon does the average diesel-powered (not hybrid or diesel-electric) freight train engine emit per ton-mile?

All diesel locomotives actually are now self-generating electrics. The diesel turns a generator that powers YOOOOJ electric motors geared to the drive wheels. IOW the electric part is the transmission between the engine and wheels. As for carbon output Assume 0.4 # of fuel per horsepower per hour. Assume the engine is run at about 50% most of the time the freight train is cruising. So for a 7000 hp locomotive, that'd be an average power output of 3500. So far the algebra gives us 1400 # mass of fuel used every hour. Most freight trains I've seen run like 4 locos, maybe more if it's a really long consist and there're more inclines to pull up. So that'd be like 5600 # of fuel for every hour that train is moving. But wait! Remember how much stuff that train's hauling! It's literally HUNDREDS of semi trucks worth of stuff, so to complicate this, you have to also know the length of run (in hours) and the load so you can get the carbon output per ton of cargo. After all that you must figure the percent by weight of Carbon in diesel fuel. Sorry, but I'm not doing that homework. Good question, BTW. Also, I did this calculation in my head for a commuter train last year and figure that the equivalent fuel mileage is like 50 mpg per person. Sure beats commuting in the family Status Urban Vehicle, huh!

Q:I know that when a coil is moved between magnets, it produces electricity. how does a generator work without magnets ?one more thing I want to know, what makes the generator turn on when the light go out ?

Doesn't. Rotor (w/ magnets) spins in a stator (coil). When power transfer switch detects a loss of line power, isolates line feed (to prevent linemen from getting zapped), lines up load feed (to house or wherever) and trips starter circuit to gen-set. Or, you go out to shed,shut off your main, plug in your auxiliary cord, and pull-start the SOB.

Q:because generating electricity is not very efficient, coal being imported from bolivia etcDoes it matter how far the stations are apart?btw dieselectric means the locomotive isn't directly diesel-driven, but runs on electricity generated by a diesel-generator inside the locomotive

The advantages of dieselelectric outweigh steam, mostly due to the high maintenance required on coal-fired steam engines. Another large factor is the ability of electrical generator to drive the traction motors required to overcome the inertia of the enormous mass of the freight when the train is starting up. Efficiency is not simply the mechanical efficiency of the system, but the ability to maintain the system and adapt it to various tasks.

Q:i want to buy a generator for our company i want to know how to calculate current for 1000kva capacity generator. and also want to know control and protection are required for the same generator please explain.

OK - You have elaborated - At that voltage you will have about 2400 Amperes. I P/E You have a generator putting out about 1 million watts. Divide that by the voltage and you get the usable amperes at rated voltage. Drop that to 380 3 phase Y would transformer. With loss through this you will have about 2352 amps. But the voltage has dropped from 415 to 380 so the amperes will go up. You will have about 2500 amps available at the output side of the transformer. Remember this is TOTAL amperes across all 3 legs of the windings. Remember that The Power is ALWAYS equal to the VOltage X the Amperage. If one goes up the other goes down. That will NOT change. Transformers are 98% efficient so you must calculate the initial loss through the primary transformet before you calculate the oiwer available for your main buss. If you have 1000 KVA before the transformer you will have 980 KVA at the out side. At 380 V, 3 phase you will have 2578 Amps. 980,000VA/380V 2578.94A OK So far? For safety you have to derate the system by 20% to prevent overload and burnout of the Generator or transformer. you have 2000 amps at 380 volts. That is on your main buss in the master control panel. You have a master breaker there feeling smaller buss lines. On each of these is one breaker per machine OR you can take sub feeder lines to sub panels throughout the factory. From these sub panels you can distribute 3 phase for motors and secondary panels for 110 or 200 single phase for lighting and hand tools. This is so complex and I want to tell you so much. How about I go there and do it.

Q:I accidentally filled my generator with diesel instead of unleaded. It already had a half a tank of unleaded so it has about half a tank of diesel. To make the full tank. Can anybody help me out please.

That won't hurt anything, the generator just won't run well because there is too much diesel for it to burn right. Take the fuel line off of the carburetor and drain it all into a can and put new gas in, it will be just fine. You can take the stuff you drained out and put it in your car so you don't waste it, you'll never know it was there if it's just a gallon or two. It won't hurt anything. But do not do this in reverse, by putting any quantity of gas in a diesel bad news.
