I interviewed ChatGPT about wood gasification

Hi guys,

I’m sure at least some of you have heard about this new AI called ChatGPT. People are getting all sorts of wacky responses out of it. I thought I’d ask it about a topic I know very well… Here’s my conversation with ChatGPT on wood gasification.

Chris: Good morning!

ChatGPT: Good morning! How can I help you today?

Chris: What is woodgas?

ChatGPT: Woodgas, also known as producer gas, is a mixture of gases produced by the thermal gasification of wood. The process of wood gasification involves heating wood in the absence of oxygen to high temperatures, causing the wood to break down into a mixture of gases, including carbon monoxide (CO), methane, and hydrogen.

During the process, the wood is heated to around 700-1000 °C, typically in a gasifier, causing the wood to undergo a series of chemical reactions known as pyrolysis, devolatilization, and gasification. These reactions cause the wood to break down into various gases, including wood gas.

The composition of wood gas can vary depending on the type of wood and the conditions under which it is gasified. Typically, wood gas contains around 55-60% nitrogen, 25-30% carbon monoxide, 5-10% methane, and 1-5% hydrogen. It also contains small amounts of other gases such as carbon dioxide, oxygen, and water vapor.

Woodgas was used extensively in the past as a fuel for transportation, especially during World War II, as a shortage of oil. However, today it is mostly used as a fuel for electricity generation or space heating in remote areas, or as a backup power source in case of power outages. The main advantages of wood gasification are that it is a renewable and sustainable source of energy, and it can make use of locally available resources such as waste wood or small-diameter trees. However, it also has some limitations, like the fact that it requires a large volume of wood to produce a relatively small amount of energy, and the equipment can be costly to build and maintain. The CO emissions are also a significant drawback, and proper design and operation of a gasifier is crucial for safety and to minimize CO exposure.

Chris: Tell me what you know about wood gasification enthusiasts in the United States.

ChatGPT: In the United States, there are a number of enthusiasts who are interested in wood gasification as a way to generate heat and power in a sustainable and renewable manner. These enthusiasts typically come from a variety of backgrounds, including homesteaders, off-grid living enthusiasts, and preppers. They are often interested in the idea of being self-sufficient and reducing their dependence on fossil fuels.

There are some online communities of wood gasification enthusiasts in the US, where people can share information and experiences about building and using wood gasifiers. Some enthusiasts have built their own wood gasifiers from plans and instructions available online, while others have purchased commercial systems. They can also be found in some DIY and renewable energy forums, where people discuss the technical aspects of wood gasification and share tips for building and using wood gasifiers.

It is worth noting that wood gasification is not without its challenges and risks, the main one being the production of Carbon monoxide (CO) a highly toxic gas. Therefore, proper design and operation of a wood gasifier is important to minimize the risk of CO exposure. Also, there are some codes and regulations to be considered by the user before installing a gasifier in their property.

Chris: Give me a list of these online communities.

ChatGPT: There are a number of online communities where people interested in wood gasification can connect and share information. Here are a few examples:

  1. The Wood Gasification Forum: This is an active forum dedicated to discussing the technical aspects of wood gasification and sharing information about building and using wood gasifiers.
  2. The BioEnergy Lists: This is a mailing list that focuses on bioenergy and biofuels, including wood gasification.
  3. The Wood Gas Vehicle Association: This is an international organization that promotes the use of wood gasifiers for transportation. They have an active online community where members share information about building and using wood gasifiers for vehicles.
  4. The Home Power Magazine Forum: This forum is focused on renewable energy and sustainable living, and it includes a section for discussing wood gasification.
  5. The Backwood Home Magazine Forum: This is another forum dedicated to sustainable living, with a section for discussing wood gasification.
  6. The Permies Forum: This forum is focused on permaculture and sustainable living, and it includes a section for discussing wood gasification.

These are just a few examples of the communities that exist online. With a quick search, you can find more forums, blogs and websites that focus on wood gasification. However, it is always important to keep in mind that this is a niche interest and communities might not be as active as others. Also, make sure to check the credibility of the sources and the information shared before taking any action.

Chris: Do a feasibility study on the fuel consumption requirements when using wood gasification to power all passenger vehicles in the US, showing calculations and sources. Remember that 16 pounds of wood is equivalent to a gallon of fuel. Include the number of acres required to grow the trees.

ChatGPT: Conducting a feasibility study on using wood gasification to power all passenger vehicles in the United States would be a complex task that would require extensive data collection and analysis. Here’s a rough estimate of what such a study might include:

Fuel consumption: In order to determine the fuel consumption requirements for wood gasification in passenger vehicles, you would need to know the total number of passenger vehicles in the US, as well as the average fuel consumption of those vehicles. According to the US Energy Information Administration, there were approximately 260 million registered passenger vehicles in the US in 2019. The average fuel economy of these vehicles was around 25 miles per gallon.

Wood consumption: According to the information you provided, 16 pounds of wood is equivalent to one gallon of fuel. To fuel all 260 million vehicles for one year, using this equivalence would require 4.2 billion pounds of wood or roughly 2.1 million tons.

Acres required for trees: The amount of land required to grow that amount of wood would depend on a variety of factors such as the species of trees, growing conditions, and the yield per acre. A rough estimate using a yield of 10 cords per acre, and assuming that all trees are fully grown and ready for harvest, would require around 210,000 acres of land.

Environmental and economic impact: However, these calculations don’t take into account the environmental and economic impact of growing and harvesting that many trees, the cost of building and maintaining the gasifiers, and the energy efficiency of the process. These are some of the key factors that would need to be considered in a more detailed feasibility study.

It is also important to note that wood gasification is not a well-established technology for transportation and is not widely used today. There are also challenges associated with wood gasification such as the carbon monoxide (CO) emissions, and the high cost associated with building and maintaining the equipment. Moreover, this scenario is just an estimation and it would require a more detailed study with more accurate data and more specific scenario description.

Please let me know if you have any other questions, or if there is something else I can help you with.

Chris: Give me a complete history of vehicle gasification.

ChatGPT: Vehicle gasification, or the use of gaseous fuels, such as wood gas, to power vehicles, has a long history that dates back to the early 20th century.

Early history: The first recorded use of wood gas as a fuel for transportation was in the late 18th century, when the French engineer Philippe Lebon built a vehicle powered by wood gas. However, it wasn’t until the early 20th century that wood gas vehicles began to see widespread use. The use of wood gas as a transportation fuel was particularly common during World War II, as shortages of gasoline and diesel fuel led many countries to turn to alternative fuels.

Post-War: After the war, the use of wood gas vehicles gradually declined as oil supplies became more readily available and gasoline and diesel vehicles became more popular. However, wood gas vehicles continued to be used in some remote or rural areas where access to other fuels was limited.

Renewed Interest: In recent years, there has been renewed interest in wood gasification as a means of producing sustainable and renewable transportation fuels. However, unlike the historical use of wood gas vehicles, which was driven by necessity, the current interest is driven by a desire to reduce dependence on fossil fuels and to find sustainable alternatives.

Modern wood gas vehicles: Today, wood gas vehicles are not as common as gasoline or diesel vehicles and there is no major commercial production for wood gas vehicles. But it is possible to convert a gasoline or diesel vehicles into wood gas vehicles, and this is being done by enthusiasts, homesteaders, and off-grid living enthusiasts. They typically use smaller-scale, DIY systems and are driven by the desire to be self-sufficient and to reduce their dependence on fossil fuels.

It is worth noting that wood gasification as a transportation fuel has some disadvantages and challenges, including the CO emissions and the high cost associated with building and maintaining the equipment. It is also an emerging field and most of the advancements and technologies are being developed in a small scale and by enthusiasts and small businesses.

Chris: Can you elaborate on the wartime use?

ChatGPT: During World War II, many countries experienced shortages of gasoline and diesel fuel, as these fuels were primarily being used to support the war effort. In order to keep transportation and industry running, many countries turned to alternative fuels, including wood gas.

In Germany for example, wood gas vehicles were used extensively during the war, as shortages of gasoline and diesel fuel made it difficult to keep traditional vehicles running. The German government encouraged the use of wood gas vehicles by offering incentives to farmers and truckers who used them, and by building a network of “gas factories” to produce wood gas. It is estimated that by the end of the war, around 50% of German vehicles were powered by wood gas.

Similarly in the Soviet Union, wood gas vehicles were used to help overcome fuel shortages during the war. In this case, the Soviet government organized a system of collective farms and state-run factories that produced wood gas for transportation and industrial use.

In other countries like Sweden, Italy, France, and Finland also used wood gas vehicles during the war, although to a lesser extent than Germany and the Soviet Union.

It is worth noting that this usage of wood gas was mainly out of necessity, driven by fuel shortages and a lack of alternative transportation fuels. These vehicles were not very efficient and had low mileage per m3 of gas produced and also produced significant amount of pollutants including CO which is highly toxic. However, they were able to keep transportation and industry running during a difficult time.

Chris: Comment on the renewable energy and carbon neutral aspects of wood gasification.

ChatGPT: Wood gasification is considered to be a form of renewable energy because it is derived from wood, a renewable resource that can be sustainably grown and harvested. Furthermore, wood gasification has the potential to be carbon-neutral because the CO2 that is released when wood gas is burned was previously absorbed by the trees as they grew. In this way, wood gasification is considered as part of the carbon cycle, which does not increase the overall amount of CO2 in the atmosphere.

However, it is important to note that the carbon-neutrality of wood gasification depends on a number of factors, such as how the wood is grown and harvested, how the gasification process is designed and operated, and the use of the generated energy.

For example, if the wood used in the gasification process is grown and harvested in a sustainable manner and the energy produced is used efficiently, the process can be considered as carbon-neutral. However, if the wood is harvested unsustainably or if the energy is wasted, the process will not be carbon-neutral.

Also, the process of gasification itself generates some emissions. For example, the process generates carbon monoxide (CO) which is highly toxic and, if not treated properly, can be dangerous to human health and the environment. Additionally, other pollutants such as nitrogen oxides and particulate matter can also be generated, depending on the design and operation of the gasifier.

Overall, wood gasification is considered to be a form of renewable energy with carbon-neutral potential, but it is not without challenges and limitations, and a proper design and operation is crucial to achieve the best results and minimize negative impacts.

Chris: Is there anything wood gasification enthusiasts should know about ChatGPT?

ChatGPT:As an AI language model, ChatGPT is a tool that can be used by wood gasification enthusiasts to gather information and answer questions about the topic. However, it’s important to keep in mind that the information provided by ChatGPT is only as accurate as the data and knowledge that the model was trained on, and that it is not able to browse the internet and therefore the information provided is limited to the knowledge cut-off date during the training, it is also important to verify any specific information or technical details provided by ChatGPT with other credible sources.

Additionally, while ChatGPT can provide general information on wood gasification, it is not a substitute for the knowledge and expertise of professionals in the field, such as engineers and scientists who specialize in wood gasification. It is always recommended to consult with experts before taking any actions, especially when it comes to designing, building, or operating wood gasifiers.

It’s also worth noting that ChatGPT is not a decision-making tool and should not be used for making decisions about the design, operation, or use of wood gasifiers. It is simply a tool that can provide information and answer questions to the best of its ability based on the information it has been trained on.

Chris the video below by Nate Hagens is a pretty good interview about the technology behind the modern AI. Having studied the earlier attempts from the 90s and early 2000s i found it interesting. I am not sure if this interview is a little too technical for most to follow as i have a strong software background but i think they do a good job explaining things. It is a long interview but should be interesting to those who want to know more about the current AI.

Hello Koen, I agree with your opinion, well, if we tried to do the wood gasification process without adding air in a closed chamber, the result would be 77% CO and 23% CH4, this would be a very calorific gas, burning this gas in the engine would create higher pressures than those reached by diesel fuel. The last experiments I have done using torified wood, where I avoid wasting energy drying the wood in the upper part and thus adding less air, indicate that the gas is more powerful.

How does that compare to charcoal?

6 Likes

Mr. Don, this is partially charred wood with minimal moisture and is still wood. I think that in the gasifier, where certain heat losses occur, it still releases enough water vapor to form hydrogen and cool the hot zone, but it forms a rich brown pyrolysis gas in the funnel, which turns into methane when converted in the hot zone (at least I think so). If the wood is properly prepared, the gasifier does not need a condensation zone and can be completely insulated and has almost no heat loss, you can imagine what kind of gas is produced. The preparation of torified wood is a relatively fast process with very little energy loss, the volume of the wood shrinks by approx. 20%. I hope that Kristjan will soon provide “official” measurements of this fuel in comparison to moist charcoal. :grin:

Yah. That is what happens when somebody finally realizes its not worth paying the annual fees to keep a domain name that is neither profitable nor popular. It also indicates like others have said (Koen, Cody, Chris, Garry, et all) that ChatCPT is a parrot reading Wikipedia and other articles without really checking sources. You are not going to learn anything you haven’t read before, unless you are exploring a subject that is brand new to you. Humans are still needed, at least until ChatCPT and its family grow up. Then, watch your back. :cowboy_hat_face:
What really freaks me out is the original art and music the AI’s have come up with. Could be considered beautiful and having deep meaning. That was the border line I drew for a point of no return on AI genuine intelligence, hope they stay nice and happy with co-existence and co-operation with Humankind. Or I have just been fooled, which may be the goal of the keepers of the Matrix.

it is garbage in and garbage out. :slight_smile: The way I understand it is it sucks in pages like google search does, and then evaluates the data on a weighted basis, and based on popularity or source it spits out an answer.

So if you have garbage for a source, say a group of people spread a lie or misinformation, it will suck it up, and can’t make any determination on whether that is a lie or not, and most likely will repeat it.

I have seen chat bots for literally decades. The scarier part about this one, is that it is MUCH harder to detect it is a not a real person. Those answers were well written and to the point. Whether or not they have misinformation or incomplete information, is mostly irrelevent. There is so much misinformation on the web, the joke is ‘I was up all night because I was correcting someone on the internet who was wrong!’ which can be a legit source and expert in an area. Which is a lot of times why I preface stuff with ‘supposedly’, ‘according to’, ‘i thought’ or ‘possibly’ or some other term that implies a vagueness because what I know isn’t always complete information either. :slight_smile:

I also find it very ironic that Musk is one of the people who said we need to wait on AI, when their self-driving car technology relies on it. Oh but wait, Musk is spending billions on AI for twitter… which means he isn’t against it as he implies, but that he needs time to catch up.
