Red Stone Engines / Re: Are these Redstone diesels?
« on: January 01, 2020, 04:29:22 PM »
anyone else notice these on ebay? they look a heck of a lot like redstones.. maybe im wrong.

That is a good idea in theory, but the UPS's were rated for backup power, not a 100% duty cycle.

yeah. That is an issue, however, you're never supposed to run them at 100% anyway.. more like under 75%. running one at 20% capacity or even 50% capacity for short periods of time, such as for tv, using your computer, etc. If you're on a budget, and have extra battery capacity or are having problesm with your genset causing problems for your equipment, it's worth the added inefficiency, at least to me anyway

there's a load of computer related DIY UPS stuff on the net, using everything from automotive battery chargers and DC->ac automotive inverters.. to hacking off-the shelf UPS units.. it's worth a look for those of you with minor problems..

might i suggest another option for you UPS users that also have a battery bank?

run a 24vDC lead to your UPS battery connection from yoru main bank. Start the UPS normally but with no load (such as off an inverter or on st power), then unplug the AC cord.. now it's running right off the batteries.. all better UPS's are basically a double inverter ac->dc->ac with their own 60hz generator.. by hooking it into your constantly charged battery bank - you fool the UPS into thinking that it has a larger capacity than it actually has. I replaced my UPS batteries with a pair of 31d Deep-Cycles which are in my basement.. translates to about 12hrs of runtime if the power's out..

If you setup a few of these, power-line conditioning becomes fairly easy without worrying about funky ST noise. just a thought... last i checked, you can get probably 50 UPS's on ebay for the cost of a house house inverter.. .

Engines / Re: Making a New Lister
« on: May 13, 2007, 08:47:52 PM »
After my original post about lister machine drawings a few months ago, I pretty much tossed the idea.

All this talk about automotive diesel off-the shelf components for a new block..

Dumb question, how difficult would it be to just take an existing diesel engine - say a Cummins 4BT, and MAKE it run at slower speeds such as the listers?? It would be far easier to deck that block, get special pistons, etc, and have large-mass flywheels made for it than start from scratch on a block. Since for the most part it's a manual diesel, no expensive sensors or injectors to clog or replace, in fact i bet you could get injectors that would pretty much flow any fuel-stock. I wonder what the engine life would be on that setup.

Listeroid Engines / Re: update on crank balancing
« on: May 02, 2007, 05:12:25 PM »
it seems it would have been cheaper to get a custom centramatic-style balancer machined. Oil-filled, and then filled with lead-filled ball bearings somewhere in the half-lb per ball range.

I've got a good vision of the balancer in my mind, such that anyone with a lathe or access to a machine-shop could make one or have a pair made, which would then be simply bolted to the flywheels.

Generators / Re: Magnetic Clutch???
« on: January 05, 2007, 09:37:41 PM »
ditto on the york, I've built many OBA systems with them.. you can find them in 1980's volvo station wagons (those come with v-belt pulleys tho) at pick-a-part places for around $25-$40 depending.... or.. you can get brand new clutches with serpentine belt configuration from http://kilbyenterprises.com/compressors.htm (no, i don't work for him, but i have met him and gone 4x4ing with him. Nice guy.)

It wouldn't surprise me if there was a larger A/C clutch available from a diesel-reefer trailer that might hold stronger.. also perhaps you can run more voltage through them (it's just an electromagnet folks!) to get more power.

On the drive-shaft, perhaps you could get a custom-machined adapter to mate the larger generator shaft to a smaller shaft that would direct-fit the existing clutch that you found.. This would make replacing the clutch easier if you burnt one out. (although it's not the grabbing action that wears these out, it's the initial startup-friction)

Generators / Re: Magnetic Clutch???
« on: January 05, 2007, 04:12:29 PM »
yeah! i just realized that you could have an induction motor running co-gen, and when the power- fails, and your cutout system engages, automatically trip the clutches to transfer to your ST generator! Add some UPS equipment to any sensitive equipment and you'd have virtually zero downtime!

Generators / Magnetic Clutch???
« on: January 05, 2007, 03:03:45 PM »
Has anyone toyed around with the idea of using a magnetic clutch (such as is used on automotive A/C compressors to engage the connection between generator and your flywheel? I was working on my jeep york-powered 10cfm onboard air-compressor system yesterday, and it hit me. If your lister was to be used for more than just power generation, i.e. pumping water, or driving something else, like a seed press.. it would seem to be simple to have two clutches, one for each device, and as you needed extra electricty as your battery banks died down, a simple relay would kick in, disengaging the mechanical device you were running, and engaging the gen-head. All with a minimum of work necessary to do so.

I'm not sure just how powerful the clutch would have to be in one of these situations, but they're just simple electro-magnets and the concept has been used for years in other technologies..

What say you?

Engines / Re: Machine Drawings of Lister?
« on: January 05, 2007, 12:13:06 AM »
i dont know.. perhaps it would be enough to know all of the specs of the engine, so you could get a custom-ground cam, and crankshaft along with a head. Just think of how long a precision version of a lister would run? Of all of the horror stories about shaft-holes drilled off center or off-90deg, i'm a little hesitant to buy a indian lister.

Engines / Machine Drawings of Lister?

Hey guys.. are there open-source plans for the lister? I think it would be pretty neat if someone here in the US was able to refine the lister down, and make their own hobby castings. There's a lot of fellows playing around with home cast-iron foundries.

Lister Based Generators / Re: calculating gen-size
« on: January 02, 2007, 09:45:38 PM »
good points everyone. Guess I need a kill-a-watt before I start sizing anything.

Right now, the only 'major' appliances I have constantly running are

2 14cuft Deep Freezers
1 17cuft refrig
4 tvs w/ associated cable boxes, and video players
2 computers and associated equipment
1 SW aquarium
home lighting (on maybe 3 hrs a day)

I guess one way to do it would be to kill-a-watt everything and come up with that total and size the gen that way,

The reason I came to this site is to research alternate energy sources mostly, the ups and downs of each, (came to here via otherpower.com ->utterpower.com (and then interest in listers) -> and then here.. in preparation for building a house. The lister seems to be a very good option (if rebuilt properly) for meeting power demands of homes that don't use electricity for their heating or cooling purposes (i'm really really convinced of annualized geosolar heating, in fact, in certain climates, I think you can do geoshaded cooling as well!!)

I want a grid-tied system with battery backup with a mix of solar, wind, and lister power sources.. (i gave up on micro-hydro as a source of energy - finding a suitable site for it seems nigh impossible or outright cost prohibitive.

Lister Based Generators / calculating gen-size
« on: January 02, 2007, 08:07:41 PM »
Hey guys.. I'm new to the forum, but have lurked about the various off-grid home-power sites, and I've got a question..

How do you calculate what size generator you need? For instance, my current elec. co sends me a bill with the average kwh per day usage. Is it as simple as taking this number, dividing by 24, and sizing your gen to be slightly larger?
