The NSR Gas Station is a six inch Victoria gasifier with the necessary cooling, cleaning, and carburetion hardware to run whatever small engine you may want to attach.
I have tried an 8hp chipper, a 7hp(196cc) 4kW generator, and a 13hp(389cc) 6kW generator and all worked very well. Below is a video of my original prototype.
I am continuing to explore the range of engines that the Gas Station will power. An 18.5hp lawn tractor is coming next.
To give you an example of how cleanly the system runs, here is the inside of the filter housing after four hours of the machine being run improperly spewing charcoal that did not have the volatiles completely off gassed:

You may want to click on the image to expand it so you can see inside. The filter liner has obviously been exposed to sooty water but there is no tar to be seen.
First the usual disclaimer: Your performance WILL vary due to fuel size, moisture content, heat exchanger cleanliness, hard wood vs. soft wood, wood species, pull rate, and atmospheric moisture content.
One of the first questions people ask is, “How long will it run on a load of fuel?” The answer is “It depends on how hard you run it.” To give you an example, a 13hp, 389cc, 6kW generator running at 3600 rpm with no load consumed 6 cubic inches of hardwood pellets per minute(or .1 l/min). On a weight basis the fuel consumption was:
Fuel Consumption = (.1l/min)*(648g/l) = 64.8g/min = 8.9 lbs/hr
That means the machine will run roughly 90 minutes between refills with the standard hopper. A standard 40lb bag of pellets will last 4.6hrs.
A load of 250W did not make any measurable difference in fuel consumption.
The Gas Station is available for $2250 plus shipping. The cart is not included.
The Gas Station Lite
For some users who may want to get into a Gas Station for minimal cost or may only want to run a 4kW generator I am working on a “Gas Station Lite”. This is the same machine as the regular Gas Station minus the primary cooler.
The Gas Station Light is available for $1700 plus shipping. The cart is not included.
