Question #1:

Which model avatar generator will produce the most electric power with the least expense?

Question #2:

Generator vs Inverter for power all day?

I am starting a business selling drinks from a ice-cream type truck. These trucks are actually empty DHL delivery trucks that I have converted over short of hooking up the machines for power. I have 4 machines each on 3 trucks and 2 machines on a cargo van. Each machine is 10 amps and need 110 volts to power them not 240. I don't know if that's start-up amperage or constant amperage. These machines are Slurpee type machines that you would see in 7/11 store or QT gas stations serving frozen drinks. I am wondering what would be the best solution to power the machines to run basically all day. The trucks are gas powered, not diesel. I am not so worried about the cost of gas to run the trucks all day if using an inverter, just trying to figure out which method would be the most sensible in providing all day power and long term usage. If I do use a generator how should I install/mount it on or in the vehicle? Also, who or where could I get them wired to do such? It seems like no one knows anything about the topic yet there are plenty of ice cream trucks and motor-homes traveling the USA which are using one or both methods, I just can't seem to find anyone who knows how or where to get it done. I asked the question before and am not getting a solid answer either way, so wanted to try again and see if someone can be a little more specific as to which source of power would be better suited. I have the room to do either in each vehicle. Also, what about back-up batteries, automatic engine start/stop switches, batteries in series/parallel, size of inverter or generator. I know I'm asking a lot but trying to get the most and best info, thanks to any who can help.

Question #3:

Need help with some electricity?

1.The power from a 10 000 V (10 kV), 200 A generator is transformed up to 400 kV by a loss-free transformer for transmission. What current will flow in the power line?
2. An electrical extension cord used to run a 2400 W mainspowered
heater is found to have the I–V characteristics: 1.0V = 8A R= 0.125 ohms.
a) How much voltage drop will occur in the cord while the
heater is running?
b) How much power will be dissipated in the extension cord?

Question #4:

I am just doing research on building my power system for a van. Now from what I understand the charge controll?

I am just doing research on building my power system for a van. Now from what I understand the charge controller regulates but also hinders power going to the battery bank. My question is a 5000w 40amp gas generator would put out more power than a 12v battery bank would receive from one of the 80amp mppt controllers correct? And if this is correct is there any way to get around the flow problem to charge the batteries fast and maximize the generators output safely?

Question #5:

1969 VW Beetle Charging System Problem?

My 1969 VW Baja Bug is having some problems with the charging system. According to the voltmeter in the car at idle, it is just under 12 volts, and with the headlights on, it goes down to 10ish volts. If a wire is disconnected from the ignition coil (with power power on but not running obviously) , the voltmeter in the car goes to 12. I hooked my multimeter up to the battery to confirm and it gave me a different reading. At idle, it is putting out about 12.3 volts and with the headlights on, it puts out about 12 volts. If I rev up, the voltage does not go up like it should. I have replaced the generator, voltage regulator, negative battery cable, and some wires going to the voltage regulator. The tension on the belt is good. If I shut the car off, the voltage from the battery goes up to 12.4. Any ideas on the cause of this problem would be appreciated. Click Here
It has an external voltage regulator. Also, the generator was polarized when installed.
Alternator kit is on the way!

Question #7:

What are some basic things or advice you can tell me about buying a portable generator?

I am buying a portable generator in order to power up to six, 500 watt halogen work lights to light up my horse arena at night. what are some things I should consider in terms of features that are needed in this application. Also, I don't want alot of bells and whistles, I need to keep as low cost as possible but still safe and quiet.

Question #8:

perkins 4.236 diesel generator won't keep steady RPM.?

I have an old diesel back up generator with a perkins detroit 4.236 4 cylinder diesel powering a 3 phase 240V Sanford 30KW brush-less generator.

the generator is failing to produce steady power because the diesel won't hold a steady RPM with load or with no load.

I have disconnected the generator from the rest of system for troubleshooting.

the generator starts and runs beautifully at first, generating proper voltage and frequency, but over the coarse of about three minutes, the rpm steadily drops until the motor dies.

I replaced the fuel filters and bled the air out of the lines, but it did not effect the problem.

I tried removing the air filter, in case it was causing restrictions, but it did not effect the problem.

I tried loosening the pressure line to each injector individually, and noticed a significant drop in RPM with each, so it does not appear to be running on three cylinders.

the generator is not new to this application, and ran for years in the current configuration without problem, nothing of note happened to this gen-set prior to the onset of the problem.

the AVR does not appear to be tied to the motor in any way or have any rpm governing ability.

I am thinking this might be a problem with the fuel pump, but would like a way to diagnose it as the problem before I replace it, unless someone who has experience with these gen-sets knows what causes this problem.

If you are not familiar with commercial diesel generators, or at least this series of Perkins Diesel, please do not respond with ball park musings.

I wish there was an old diesel mechanic out in the bush here with me.
This is an old 4 cylinder Perkins.

There is no electronic or mechanical governor like in a modern generator. There is no system that uses the rpm of the motor to control the throttle.

the only speed control is on the fuel pump. there is a throttle lever that controls the output pressure, and that's it.

the fuel pump can be shut off if there is low oil pressure, but I don't believe the low oil pressure kill solenoid is variable, it is on or off, and it is the same solenoid used to kill the engine when the key is turned off.

Question #9:

What do i need for my BRICK making business Project?

I want to start a brick/ blocks making business in africa i have the money, but lack the expertise in this . My question is what do i need in other to have a full functioning small size brick making plant? Yesterday i was charting with a supplier of brick making machinery online, he send me information of a semi-auto machine that can produce 19000 pcs/per8hr and cost about $20450. I would like to buy Diesel Generator to generate electricity for this project as i had been using this before for a juice project. But when i ask him about power consumption he said the machine is an Electric hydraulic forming system, but i do not have idea what is hydraulic oil/liquid forming system. The machine has 27kw GRS power what this mean in terms of fuel consumption? thank you for your answer.

Question #11:

How do you measure the current of a generator (with a multimeter)?

I have a computer cooler fan, which I am using as a generator as part of a school experiment.
I'm trying to find the amount of power it can generate by using a hairdryer to move the blades of the fan.
I know that voltage x current equals power and my problem is that I can't get the (digital ) multimeter to measure current properly!

I've tried moving the red lead of the multimeter to the other terminal and it made no difference

Also, is it possible to measure the resistance of the fan? (seeing that current= voltage/resistance)

Question #12:

Per unit. the steam gen can supply any additional power that is needed at a constant marginal cost of 10 cents per unit. when electricty costs 10 cents per unit, demand is 200 units per day..
How much should govt charge for electric power????????????

Question #14:

Is it possible to use an incubator for chicken, duck, or turkey eggs in an area that has regular black outs?

I live in a rural area that has just about daily black outs (or brown outs). They last from 5 minutes to 12 hours normally. Usually in a day we'll lose power for 1-2 hours. I would like to use an incubator for my eggs, but I'm not sure if it is possible due to the power problems. I don't have a generator, although I've considered getting one. Any advice would be much appreciated. Thank you.

Question #16:

could 12 volt generator charge a 12v battery to power a 30Kw motor?

PLEASE READ:
So I had this idea on how to power a motor and make things lighter, I wont tell the whole story. Anyway if i had a 12v generator to charge a 12v 8amp battery could that power a high powered motor full speed until the generator died, regardless of the 8 amp etc?
Thanks!
oh sorry I meant a Generator equivalent to the motors watts so a 30Kw generator.

Question #17:

Which is better on a boat?

I'm looking at either having a generator installed or a voltage inverter and battery bank installed. I know some boats have both, but I can't afford both. My budget is $8500, and I can get either one at that price installed. I have no experience with either, but I would like to get the best bang for the money. This is on a 43' sail boat. Need to get an answer this week to the shop. I sail around the world with this Cheoy Lee Power/Sailing vessel.

Question #18:

Do they still make generators for bicycles?

What I meant is generator to power the headlight(s) and tail lights for bicycles.
All I see is lights power by batteries. It'll work. But I prefer generator.
About those sales people. They say it wears down a tire. That's hog wash. Because I use generators for years and it never did.
Ofcoarse it quit working when you stop. I'm satisfied. I don't want to go through the trouble of reminding my self when changing the battery.

Question #19:

What portable indoor electric heater have you used and recommend? I'm looking for best affordable heating.?

When we lose power and go to generator during winter storms, we have to run extension cords so electric is best, Can't stand smell, mess and danger of kerosene. I've looked at portable heat-pumps but they don't work if it's cold outside and require exterior venting.

Question #20:

I want to play music at a party from my car. I've been told that it's ok, what could go wrong with my car?

Ok, so a person told me they have done this before, play music from the car, open all the doors so the sound comes out and just switch the car on every 2 hours for 5 mins to get the acumulator filled up and switch it off again. It all sounds so simple but I'm so worried I might damage my car. I'm organizing a beach party for some friends around 30 people coming and we couldn't find any way to get sound going, or how to power speakers without a generator (as we have no access to one) So I've decided to use my car. The car itself is not in the best state but the battery is brand new. So that should be good. What could go wrong? How often should I power the car?
Any suggestions? I want anything you can think of so I can be sure what I'm doing is ok.
