Q:If you obtained all of your energy from a diesel generator, how much diesel would you save per year by switching from incandescent to CFL? Diesel has an energy density of 36 MJ/L and your generator operates with 40% efficiency. Incandescent bulbs consume 60-100W, while CFL consumes 15-25W.

1 Kwh 3.6 MJ. If you use each light 4 hours per day, and each was 100 watts, that is 4 x 100 x 10 x 365 1,460,000 watt hours per year. That requires 1,460 x 3.6 MJ 5,256 MJ. / 0.4 efficiency 13,140 MJ. So you need 13,140 / 36MJ/L 365 Liters of diesel. If you used CFLs, at 25 watts, the answer is 1/4 of that, so 365 / 4 91.25 Liters of diesel. So the savings is 365 - 91.25 273.75 Liters savings. At $1.25 per liter, that is $324.19.

Q:I just got sworn in a few weeks ago to the navy, as an engineman. I was wanting to be on a carrier but didn't know if there was any jobs for the EN rate?

Most likely work related to the diesel generator or as an auxiliaryman. All propulsion work on a carrier is done by the NUCS. edit Enginemen are often assigned as small craft engineers, operating the engines on various boats carried by the ship.

Q:I planned that the factory be fully mechanised. Public power supply is very poor. I wanted to purchase diesel generators but i have been advised by a friend that solar generators are more cost effective. Is solar a good source of energy to power such a factory?

Yes, it can be fully solar. Very power comsuming factories are autonomous. If you dont find how to, if you want e-mail me and i will put you in touch with some companies. For your info, some companies not only are autonomous, they resell power while they dont use it.

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:If the electrical grid fails and takes years to re-establish, how will the plants cool down?

Q:How many watts would it take to run a small cabin with just basic lights, mini fridge, stove, maybe a small tv? I was thinking a 6000 watt diesel generator.would running it every day ruin it?

6000 is probably about right, and they are designed to be run regularly. Make sure you do the research, a $600 generator will probably only last you for about 2 years, then you will have to buy another one. Make sure that you go with an industrial one.

Q:Could I use red diesel in a diesel generator legally in the UK? Can I add vegetable oil to this and if so, in what ratio? Where are good sources of vegetable oil?

Red diesel is agricultural, no tax or tax reduced. The Red is only a dye to distinguish it from tax paid diesel. However using it illegally can result in very hefty fines if caught. Used and cleaned vegetable oil can be mixed with diesel, actual proportions I'm not sure of, but I think 3:1 oil to diesel. There are probably sites that explain in more detail. However why it has to be used veg. oil I don't know.

Q:1. are backup generators constantly running, so when the lights go out to the people inside it seems like they have not?2. what do they run off?

They are not normally running. If power fails there will be some automatic emergency lighting powered by batteries which should allow the backup generators plenty of time to get started. They are often diesel powered. You can hope that they are reasonably maintained and tested from time-to-time.

Q:hi i covered diesel motor with sheet metal and a guard needs to protect a person from accident.etchere is some info abt cover: it is ventilated. the box mounted securely over the motor. it has exposed belts it combustion(diesel engine) and it is located in cerro alto , guattemala, the voltage is 120v and its 12 hp and it is driving a corn grinding machine and its indoor.so help me plz thanks

If I understand correctly ? You have a 12 HP deisel generator delivering 120 volts- mounted inside a structure 1 Make sure all belts and controls are propertly protected and filtered air is provided to the engine. 2 Pipe the exhaust through the roof and outside the building 3 Provide proper electrical wiring and fuses 4 Provide a fire extinguisher (corbon Dixoide) near by 5 Provide safety shut-down switch on corn grinder 6 Mount Generator as far from grinder as possible.
