Focusing primarily on the supply of alternative energy equipment including the legendary JKSon Lister type diesel engines, ST alternator heads in single and three phase.

We are currently putting the equipment in the field to generate off grid power for our own use and research purposes. Some of the JKSon engines lend themselves to experimentation with waste vegetable oils and vegetable oils produced on farm.

These engines are not turn key solutions but require a certain amount of mechanical ability and offer a rewarding DIY experience - these slow revving engines are produced in a developing country at an affordable price and will deliver long life if they are cleaned and checked prior to use.

They are a simple cost effective power solution to run a myriad of belt driven equipment - spare parts are readily available and at a reasonable cost.


Something as simple as a small lawnmower engine belted to a car alternator can do a wonderful job of charging batteries very efficiently.  Most lawnmower engines have crummy mufflers...this is real important, noise pollution is intolerable.  It is best to use an oversized engine...run it slow and gear up the alternator.  It will run quieter, and last longer.  5-10 horsepower is a good match for a 30-50 amp alternator. Home Power Magazine has had some excellent articles about building one of these. There's another excellent article on how to build one at .


Here's my freshly poured floor, I added a step to my shop back door with the overage.
This mount system is a bit of an experiment. I've based it on how old logging operations used to set
their engines in a bed of clay. My Foundation Block is sitting in about 6 inches of clay.
I planned it so that once my floor was in, my crankshaft is at a comfortable height.
Prior to the pour, I had placed 1/2 inch plywood around the block, after the concrete cured,
I removed it leaving a 1/2 gap between the floor slab and the block.
Will post an update of how well this isolates the vibrations.

The heart of the system is a pair of Outback FX3048 inverters stacked to give 120/240 volt output. The well pump is the only 240v load normally, but there’s a 240v 1-ton minisplit heat pump that could be powered up if necessary. The battery is minimal since I’m on grid. It’s 230 amp-hours, which is a little over 11 KWH at 48v. At 50% depth of discharge there’s a bit over 5 KWH of useable capacity, enough to furnish the base load for a few hours. To go beyond that, plenty of sunshine is needed or a 48v power source of some kind.
