Aternate Energy: The Gasifier
The Walls of Freedom Ch 19
A gasifier requires some mechanical aptitude to build. It is a device that you can build yourself but there are some companies that offer a build kit. TacticalWoodGas.com is one of the companies offering a full setup for purchase.
A gasifier takes wood and extracts gasses from the wood to use to power an engine. The engine could be gasoline or diesel powered. The gasifier works similarly to a steam engine but instead of using steam you use the gasses that the combustion of the wood produces.
Imagine sitting around a campfire, you put a log on the fire and it heats until it begins to sizzle and pop. When this begins to happen the wood has reached a temperature where the internal gasses begin to release. A gasifier can capture and control these gasses. Then they are inserted into the engine to power it. The engines can be used to power vehicles, tractors, generators, etc.
Technical details from Wikipedia:
" In a gasifier, the carbonaceous material undergoes several different processes:
The dehydration or drying process occurs at around 100 °C. Typically the resulting steam is mixed into the gas flow and may be involved with subsequent chemical reactions, notably the water-gas reaction if the temperature is sufficiently high (see step #5).
The pyrolysis (or devolatilization) process occurs at around 200–300 °C. Volatiles are released and char is produced, resulting in up to 70% weight loss for coal. The process is dependent on the properties of the carbonaceous material and determines the structure and composition of the char, which will then undergo gasification reactions.
The combustion process occurs as the volatile products and some of the char react with oxygen to primarily form carbon dioxide and small amounts of carbon monoxide, which provides heat for the subsequent gasification reactions. Letting C represent a carbon-containing organic compound, the basic reaction here is
The gasification process occurs as the char reacts with steam to produce carbon monoxide and hydrogen, via the reaction
In addition, the reversible gas phase water-gas shift reaction reaches equilibrium very fast at the temperatures in a gasifier. This balances the concentrations of carbon monoxide, steam, carbon dioxide and hydrogen. " read more...
The technology for the gasifier has been around since the creation of the internal combustion engine. Europe used the gasifier extensively during the great depression to power vehicles.
Volvo had a gasifier powered vehicle in commercial production at one time.
Where you locate the gasifier in relation to the engine is only limited by your imagination. Folks have installed them in truck beds, bumpers, trailers, etc.
In a grid down situation you will need to grow a very big garden to sustain your group. Without gasoline your tractor will be useless. However with a gasifier to power it you are back in business.
You do not need huge logs to power your gasifier. Wood chips and forest debris work just fine. However, you will need to make some engine modifications. The fuel from the gasifier can't be put into your gas tank. The gas needs to be fed directly into the engine.
There is an element of danger as well. You are dealing with volatile gasses. The system needs to stay sealed. If you develop a leak and have a spark nearby it will result in an explosion. You do not want to breath the gasses from a leaky gasifier either. If you use the gasifier to power a generator you may consider building a berm between your home and the gasifier system.
The gasifier can also be used in tandem with water pipes to create a hot water system for your home.
In a SHTF situation the gasifier is quiet but the engine it runs will not be. This may be a red flag for refugees during the "die off," the first 60-90 days. After that you could use it to effectively power all kinds of machines.
The gasifier is one of the practical exercises Johnny presents in his book, a prepper guide called Absolute Anarchy. It is written based on just that, a state of absolute anarchy. He has written the book in five parts: 1. What can happen 2. How to prepare - prepper questions, survival needs, bartering, etc. to get you trained with 49 practical exercises to accomplish that goal 3. Group survival considerations 4. Militia organization and operations 5. Supplemental reading with much more information on how the executive branch of government got so out of control and overpowered the rest of the government. Johnny also provides fact checks, additional exercises and additional information for each chapter at AbsoluteAnachyBook.com.
Additional Topics Discussed in the Interview:
New threats since Absolute Anarchy was completed
Maintaining Judeo-Christian beliefs after the fall
How did the US get to the social safety policies it enforces today
Current teachings about the history of the US to today's youthful citizens
How the federal government uses social programs to control states.
