Q:I am looking for a portable propane generator primarily as a home backup. I have a couple models in mind but have no clue about the quality. they seem to have good reviews, but wanted to ask in here anyways. i'm looking at the Sportsman GEN7000LP or Powerland PD3G8500E Tri-Fuel. anyone have experience with either of these? or can recommend a similarly capable brand/model?

Why a propane unit? Propane cost more per gallon that gasoline or diesel. If you have access to natural gas it would make more sense.

Q:For hydropower how much MWh can be generated with same capacity plant?. (Because plant never run for 24 hours of the day we need a factor to calculate above value)

just multiply 100 MW by the number of hours in a year to get MW-hr per year 100 MW x 24h/day x 365.25 day/yr 876600 MW-hr / year If it's not running 24 hours a day, just substitute the correct number. .

Q:Couldn't one say with certainty they are changing the environment in ignorance?

Depends. In MOST cases they do, for heat at least. At least 1 is STILL using a Jacobs wind generator installed almost 80 years ago for electricity!

Q:What is the maximum power of a diesel generator

The diesel is ignited and the mixture is heated and the volume is rapidly expanding.

Q:I know that various types of locomotive's produce different amount of horse power. Here's the question: A single locomotive (any type) about what would be the average speed it could gain in 0 to 4 seconds on take off. Any smart A** answer will be reported for abuse, Thank you.

Others here with more knowledge on diesel locomotive mechanics and operations can give a better answer but because most diesel locomotives, particularly road-switchers, are not rated/geared to accelerate that quickly in that small amount of time (now an electric locomotive is an entirely different story), I would guess no faster than between 10-20mph in the timeframe you noted, 0-4 seconds. Perhaps something like an EMD E-series locomotive (which is rated for speed carrying passengers) could make the best time but again, I would guess no better than maybe 20 mph in 0-4 seconds.

Q:I read about it in an old Mother Earth news (1993?) The car was mainly powered by the gen. The batteries would only kick-in for hills, boost of power, etc. I am interested in this design, anyone know if it works well? Can I use a 480volt 3ph gen-set to power motor/Drive for more efficiency/power? I already know about the volt,prius,leaf.

Good luck driving a car wiht a 10 horsepower motor.

Q:I live 30 miles east of Seattle in an area that is frequently without power. Up until this year the outages were less than 48 hours but this year we have had repeated outages, one of which lasted 6 days after a stronger than usual windstorm. I had to scramble to find somewhere else to be. I lost several days of work, all the food in my refridgerator and freezer. At what point does it make sense to just install a standby generator?

I decided to have a portable generator with manual transfer panel while my new house was being built. It uses a deep well for water, and without electricity we can't even flush a toilet!

Q:i would like to get the machine that is at least 2000 0r 3000 kw

waw. That's a lot of energy for just a house. You got to be kidding me. okay, you can find diesel generator if you like, but you need to keep storage of diesel enough for it.

Q:Hi everybody. well I buyed a welding machine, and I need a portable generator for use the welding machine, but I dont know the generator capacity to use it, if the welding machine is 50 to 250 amps, but I just use from 100 to 200 amps, Can I use a 6000 watss Generator? or I need more power?

About 15KW is needed to run a welder. Preferable is a diesel drive unit. Read the label plate on the welder, it will give the maximum draw needed for the supply side. Double that for the generator rating needed.

Q:Actually , I heard someone talking about diesel generators and that voltage required, he said two types of diesel generators for electric furnaces in steel industry , the first 16000 voltage, approximately , and the second 32000 voltage I really want to know what does he meant .

Either could work. I don't know what he means.
