The Biomass Wood Gas Stoves
are Going Away Forever

(ONLY 2 types Available...See Below)
NOTE: The Stoves MUST be ordered from the links on THIS PAGE ONLY, anywhere else on or KPC will show OUT of STOCK

As many of you might know, anything in the survival / preparedness field is selling like crazy.  Guns, MRE's, camping equipment etc... This includes the biomass stoves we sell.  The manufacture just got a limited shipment of the stoves in stock, and since it is us at that gave them their biggest kick start when they started (thanks you to guys), we are getting a special offering of the stoves.  I expect these to last under one week, so get them while you can, it will probably be MONTHS before I can get more in stock.  If you order goes through, then you got a stove, if it says OUT OF STOCK or will not add to the cart, then its out of stock and you missed it.

The WoodGas Campstove LE is the smallest and lightest product utilizing WoodGas technology. Measuring just 5" in diameter and 6.5" tall, it provides a hot fire from twigs and chips in the smallest possible package. The stove, pot holder and carry bag (included) weigh 23 oz. One load twigs burns for about 10 minutes, providing 10,000 btu/hr of cooking heat. An excellent solution for individuals to boil water or cook a small meal.  This stove weights 1 pound 7 oz.  That's LIGHT, yeah..its not the 4 oz that your super titanium brunton stove is, but as the logo for the stove goes, ' pack the stove, NOT your fuel'.  If you are some super snobby back packer who pays extra for titanium cookware and carbon graphite hiking sticks, you won't like this.  If you are a normal person you'll LOVE it.




The WoodGas Campstove XL is a larger cooking stove, optimized for longer cooking times and higher heat. One load of twigs will typically burn for 20 minutes, while producing 12,000 btu/hr of cooking heat. It measures 9" tall and 6.5" in diameter, and weighs 35 oz. The campstove XL is the perfect size for cooking complex meals or meals for small groups. As in other WoodGas products, fuel can be added during cooking for longer burn times. Compressed wood pellets also work very well, burning for 3 times the burn time of twigs.  This is a larger version of the LE stove (the first one released).  I personally use my XL a lot more than I do my LE and I keep an XL stove in a cooking pot, that is just slightly larger than the stove, in my truck during the winter.  I have a small axe, saw and I have some soda bottles filled with wood pellets.  So no matter where I am I can melt snow for drinking water.  I can get my own fuel (the axe and the saw) or I can use the pellets I have.  Since I am not doing any remote driving, its kinda not needed, but I did it anyway as an experiment.   I have had excellent use toasting marshmallows in it on cold nights when at friends.


Woodgas Fireplace



The WoodGas Fireplace employs the air driven technology used in the WoodGas camp stoves to provide a clean burning fire in a patio fireplace package. Like the camp stoves, it runs on electricity to power a fan which gasifies the wood and then burns it. The fireplace is tuned to provide a taller flame for patio use.

The fireplace includes a lid to protect the fireplace from rain, and an AC adapter for power. The fan has an adjustable setting so that the intensity of the fire can be adjusted as desired.  On these cooler days, this is a great item to have outside or on a patio... it sure beats those dumb metal fire pans  for sale at home depot or lowes.

Answers to some really really stupid questions Steve has gotten over the years regarding the biomass stove:
A:  its not a damn light saber, don't think its some magical thing that will heat your swimming pool.
A: are NOT going to replace your furnace with it, NO you are not going to use it inside.
A:  NO NO NO NO it is not rated for indoor use, EVER.  not unless you want to kill yourself.
A:  NO.. there are NO stirling engines that  you can BUY to make electricity from this stove.
      You'll find some companies sucking on the government tit making stirling engines that cost
      many many millions of dollars but not one damn engine is available for sale TO YOU let alone
      available for purchase on the net.  Any engine you do find is a damn worthless TOY.
(note: do not send me links to any stirling engine websites)

CAPTURE, STORAGE and REUSE of Gas from The BioMass WoodGas Stove !

The Gas you
See is Gas
From the
Wood Gas
Stove that
I captured,
stored and
then used.

50 but I used some before I took the photo
I did not even use a pressure regulator, I just
cracked a pair of valves to let the gas through

Using a gas cooler, several filters and a compressor we pulled gas off the biomass woodgas stove before the gas was burned at the top and we then stored it in an air tank and days later ran the gas back through a modified propane stove.  We'll have a video coming out regarding the easy capture and reuse of gas such as this.

If you want to know how much gas can fit in an air tank like this one
see the Fuels Video 1 - Gaseous Fuels at

If I can do this, then I can also run my generator and vehicle from this gas....and I'll demonstrate it later.  :)

There is a lot of excitement regarding biochar, and there are many ways of making it, but first let me tell  you what it is.  C.  Its just C.  C is the elemental symbol for Carbon.  If Cellulose is C6H10O5 then biochar is cellulose that has had the H's and the O's driven off by heat.  These get driven off as flammable gasses that are made of C's and H's, as well as Carbon Monoxide (CO) and some CO2 and H2O, and what you are left with is just Carbon BUT... the Carbon made is full of micro holes and has a lot of surface area.  When this carbon is added to the soil it becomes a rich black soil.  The carbon will capture and hold moisture (rain) rather than it just running off or going deeper into the ground.  It provides a nice microenvironment for bacteria that is beneficial to the soil to grow and flourish so it adds to the ability of the soil to grow better plants.  There are lots of photos showing side by side crops, with and without biochar, and the biochar crops are higher, bigger and have more 'fruit' than the other crops.  Its inexpensive and easy to make and will benefit everything from potted plants to the largest farms.  you CAN make biochar in the WoodGas stove, and its easy.  When there are no more yellow flames coming from the stove (which are the flammable hydrocarbons leaving the cellulose) then the biochar is ready to be quenched.
Get your Twigs, Wood, Pine Cones, Branches etc..
gasifying / burning nice and good.
 It does not take long, watch the fire gasification settle
down and you'll see the carbon content forming
When there are no more yellow flames and you just
have glowing coals of wood, then....
dump the entire contents of the stove in a pot with
 some water in it to cool off the biochar
The twigs and wood are now all charcoal, carbon (C), also known as biochar
and its ready to be mixed into the soil of your garden or farm.
Its fragile and crumbles apart in your hands.  Its NEAT Stuff !
This works in the LE or XL stove but you can Do this in the WOODGAS FIRE PLACE.   It holds much  more wood and it comes with a very nice lid.  Instead dumping the contents into a pot of water (which is fine) all you need to do is put the lid on the fireplace and turn off its gasification fan.  The hot charcoal will smother and cool down just fine on its own.  Put it in your pots and plants and garden and watch it grow even better.

Yes, we have noticed things slow down with the economic depression in the USA.  Where in the past Steve and Roy did NOT have time for any external consulting, at this moment we do have time to do some consulting for some clients.  Rates vary from $100 to $250 / hour.  Depending on what we are doing.   General consulting is cheaper, patent work and licensing consulting is more expensive. Working with a large corporation with lots of bureaucracy and rules is VERY expensive.  For a lot of customers 2 to 4 hours is enough.  Either Steve or Roy can cut through BS and answer questions very quickly.  Tell you the best practice, what works really well today, and what may work very well tomorrow.   Steve is exceptionally good at getting projects off the mark and rolling with damn straight common sense and excellent return on investment figures.  In general, my attitude is that I'm suppose to save you many many times the amount of money you pay me.   So if you have a significant energy project, something that you are putting into a farm, grid power, a new housing development or especially if you have a product you are working on, you'll benefit from our decades of knowledge and experience.  Yes, we DO sign Non Disclosure Agreements (NDA) with customers and don't worry about us 'stealing your idea.'   Between Roy and Steve we have enough ideas to fill up 10 life times, we don't need to steal yours.   We'd rather see you succeed.  Contact Steve at  support (at) knowledgepublications (dot) com.  It does not matter if you want to do solar, hydrogen, biomass, fuel cells, internal combustion engines, vehicles, stationary, stirling, jet engines, patents or even advanced organic chemistry.  Between Steve and Roy we can handle almost any subject and if we can't, we know the world class expert in the field that can and we'll send you to him or her.  Either way, we'll get you taken care of and moving forward with confidence.  - All my best - Steven Harris.
