Q:1. Both fans are running2.Both fan is running 3.Both diesel generators were serviced 4.Both diesel generator was serviced5.Both diesel generators had been serviced. / Has been servicedWhich one is correct, and why?

Both fans are running is correct. You are talking about more than one item, therefore the plural are is correct. Both diesel generators were serviced is correct, for the same reason. The first part of the last sentence, both diesel generators had been serviced is also correct if you are talking about the past historic tense.

Q:I know they are more expensive.

Yes. But they also burn much hotter in the SOFC.

Q:I have noticed that many people leave their computers on all day for some reason. I would like to know why and if its better or worse for the computer than to just turn it off. Also, is it more efficient to leave it on?Anyway, the only thing I would like to know is why do many people leave their computers on all day and if you are one of them, why?

I leave mine on all the time. I only reboot weekly. It doesn't hurt anything and I don't have to boot every time I want to get online.

Q:can caterpillar diesel generator generate power for 1 month without any shutdowns? which is generator good GAS or Diesel?

machines are not design to run for month of course yes. Most common I know is diesel generators. But if you have fuel gas much better as gas normally has lower operating pressure and much pure in composition so lesser maintenance in the end. But not seen any caterpillar of gas design.

Q:if a diesel generator(say of negligible mass) is used to power an electric car powered by an electirc motor how efficient will it be when compared to a car that uses an i.c engine thats uses diesel directly?

Direct use of the diesel engine to run the car is more efficient. With the other option, there is a chain of energy conversion each involves a loss.

Q:Basically, I want to set up the new homestead off grid and would like to do it with a diesel generator to a DC disconnect, to a charge controller, to a battery bank, to the system meter, to the main DC disconnect, to an inverter, then to an AC breaker panel. Just like a solar array system but using the diesel instead of panels for the first year or two. The home will be using no more than about 22kWH daily. I guess the main question is how do I use a diesel generator in place of 19, 210W solar panels without running the generator 24-7?

Well, you're hitting one of the major problems of the modern age: storing electricity is very expensive. Batteries are bulky, costly, and you lose ~20% of your power just going in and out of the battery (the inverter will cost you another ~10%). But if you're willing to buy enough batteries you can store as much electricity as you want.

Q:Diesel trains use electric motors because the low-end torque is much greater than a mechanical drive drive train, I was wondering, since low-end torque is essential to starting with heavy dead weight, why more trucks and SUVs don't have electric motors on the wheels?

There are a lot of hybrid vehicles out there. The diesel locomotive is a hybrid the internal combustion engine/s turn generators which in turn power the wheels. Other heavy equipment such as used at strip mining sites also uses the same technology. But in general it is cheaper, and more reliable to have as few of moving parts as possible. A hybrid vehicle has more systems to fail then one with gear drive. Also in the case of locomotives that additional weight required for such systems is a benefit, while in a over the road vehicle is it a liability.

Q:And WHY?

Hydrogen you can install a hydrogen on demand generator on any gas or diesel engine. This is the most cost effective thing to do right now it adds Hp reduces es emissions increased gas mileage 20 to 60% or better.

Q:I Live way out in the country and have a diesel generator.I want to switch to nuclear because it could be cheaper. I have plenty of land to dispose of any nuclear waste.

Well, get 20 tons of lead and concrete. Make a steam generator. Make heat source using illegal and expencive radioactive materials. Die from cancer, since you have no idea what youre doing. Im just kidding, just put the uranium right the diesel generator, it will work fine.

Q:Hi,I read an article and it said This implies, that more or less all customers of Esson, who own appliances dependent on permanent electricity supply, dispose of their own emergency Diesel-generator installed on their premises.I try to understand it, but I think it is grammartically wrong. I think it should be This implies that more or less all customer of Esson, whose own appliances depend on

who own appliances and whose own appliances are both correct but they mean different things. The first one is saying those people OWN (have) appliances. The second one is saying those people have their OWN appliances. The first 'own' is a verb, the second 'own' is an adjective. In the text, a simpler way of saying it is: This implies that more or less all customers of Esson, who have appliances that depend on electricity supply. .
