Generators / Cost per kWH / fuel used per kWH
« on: March 25, 2007, 03:26:39 AM »
Lately I've been interested in the cost per kW when making power with a Petteroid, Listeroid, Changfa and any other fuel burning generator.... at different speeds and with different gen heads...

Martin Nile reports that his Changfa consumed .127 of a gal per kWH of electricity... that's .30 cents per kWH @ a fuel cost of $2.40

James Lerch reports that his Changfa used .09 gals per kWH at a load of 9kW...

Thats a cost per kW of .21 cents per kWH @ fuel cost of $2.40

Any other data out there???

Petteroids / Filter and Top eng oiling

I've recently installed a filter and top end oiler on the Petteroids... so far works great.... it's really nice to see a bit of oil getting to the top... I'll post some pics soon...

Generators / a better sign wave generator?
« on: March 03, 2007, 04:04:43 PM »
I ordered a couple of belt drive heads from these folks... IMO a better deal than an ST....

Brushless, good sign, lifetime guarantee on diodes and caps... made in the US... and cost is about $500 for 5kW...

General Discussion / First Mike and now Doug WTF ??????
« on: March 03, 2007, 01:49:48 AM »
I see we lost another good resource of information...  Lister Mike left a while back... got pissed off by Mobile bob... and now apparently Doug is gone???
Pissed off by one el retardo mentalbum...
Gee with a name like that how can you take the guy serious??? actually he seems well informed... and entertaining...
But Doug had like 4,000 posts... not really but it was up there... and he was always helpful... and super knowledgeable about how sparks are made...
Some guys take this forum stuff pretty seriously... I know I've gotten it too deep on the infopop forum from time to time...
Maybe a little break might be a good thing?
Anyhow Doug, thanks for all your advise...
and if you are really gone be sure to drop me a line when gus is up and running... 
Good Luck,

Petteroids / Ideal RPM
« on: January 12, 2007, 03:02:43 PM »
I think the the Petter runs best at about 1000-1200 rpm ... my engine are really smooth at this speed and seem like they could run forever... ... I've noticed that arrow rates there engines  at 400-800... IMO this is too slow.. the diesel vibrates a lot when run this slow due to compression / power stroke impulses... and efficiency is likely not much better at this speed than it is at 1200... the  indians run the engines at 1500 rpm when direct coupled to a 50Hz / 4 pole gen ... but at 1500 the engine is shaking pretty good...  we use 60Hz power which requires 1800 on a 4 pole gen.. I wish someone made a 6 pole / 1200 RPM generator so they could be direct drive at lower RPM... indian manufactures say the engine will run at 1800... at this speed the things shake like mad.. 1800 might be OK for a short time...  but at this speed I think efficiency, reliability and my nerves are being compromised.. 

Listeroid Engines / Harbor freight generators

I picked up a couple of these at HF...

they are brushless and relatively cheap.... Hmmmmm... I mean inexpensive... Does anyone have experience with them? 

Listeroid Engines / Add to this order?
« on: December 14, 2006, 02:16:33 PM »
This is a copy and paste from one of the Biodiesel forums

I will be picking up several Listeroid "short block kits" in Portland this winter. When combined with matching head kits (available separately) a complete listeroid engine is the result. The cost of shipping these huge hunks of iron is substantial though and can add another 50% to the cost. I also hope that the more that can be purchase at once the better a deal we can get individually.

Both 6/1 and 2/12 listeroids are available.

6/1s should cost in the neighborhood of $1300 and 2/12s about $ shipping.

My anticipated route from Portland OR will be due south to southern CA and then west to Autin Texas...then north back to Alexsandria MN.

If you are anywhere near this route I may be able to cut your shipping cost significantly.

Email me if you are interested in this group buy. I am not sure if this will work out but am willing to at least give it a try.

Listeroid Engines / Building engines in India
« on: June 25, 2006, 03:10:05 PM »
Building an engine in india is different from here... companies like Briggs, or Techcumsen make or have their parts made to thier specifications...¬  remember in india everyone uses the same engine designs... (petter or lister) so parts are available from many differenct suppliers...If you are building engines in india you start¬  by getting parts from suppliers like this these...
then you assemble it all like this...

BTW I've noticed that for some reason folks in asia like to work close to the ground...
then when you're done it looks something like this

This was posted by Dana Linscott on the infopop forum...
supposedly they are being run on veggie oil and have accumulated of 15,000 hours.. I was curious if any of the members here were aware of or have any information about the installation?

I have one client who wanted to produce electricity nearly 24/7 AND use the heat generated to provide part of the space heating for their warehouses. I almost lost them as a client when I suggested using a room full of two cylinder low speed gensets rather than a bus sized conventional single engine diesel generator.

There were a LOT of reasons for my suggestion...but the biggest was that if it proved neccesary to repair the "generator" due to wvo use it would be cheaper to do so with the simple small engines of the listroids...and the rest of the gensets would continue to generate electricity/revenue during any such repairs.

At nearly two years only minor repairs have been neccesary due to a very careful maintenence regime and a thorough instepction of each prior to initial operation.

Some of the listeroids are approaching the 15,000 hour mark with no repairs at all. I am really impressed!

If a second client decide to do this I will try to offer a "group buy" of the listeroids piggybacked on their order. Until them I think Utterpower is probably the best source.
