A handmade wood-fired tricycle, built with reused parts and a rear boiler, draws attention by showing how steam, monitored pressure, and mechanical creativity can transform scrap into a rural vehicle.
A Brazilian inventor identified as Joel, associated with the channel Professor Pardal Brasil, built a handmade steam-powered tricycle, fueled by wood and assembled with reused parts.
The vehicle has a boiler installed at the rear, pressure monitored by a gauge, and its operation demonstrated on a rural road, without the use of gasoline or diesel in the presented movement.
The creation was the subject of a report by UOL Carros.

The Brazilians who saw value where everyone saw contaminated plastic: inventors create a patented system that recycles dirty packaging without generating effluents, win a Latin American award, and take green technology from Brazil to Geneva.
On the occasion, the vehicle was described as a steam tricycle made in the interior of Minas Gerais, with a handmade structure and intended for demonstrations and small movements, without indication of registration or clearance for regular circulation on public roads.
In the video, the vehicle appears with the appearance of a customized motorcycle, extended handlebars, three wheels, and a rear set consisting of a furnace, reservoir, and exposed mechanical components.
The movement occurs after the wood heats the water in the system, producing steam under pressure and activating the mechanism responsible for transmitting force to the wheels.
Wood-fired tricycle uses steam to generate movement
The principle used in the tricycle is similar to the operation of old steam engines.
The burning of wood heats the water stored in the rear set, and the generated steam moves pistons connected to the vehicle’s mechanical system.
The internal pressure is monitored by a visible gauge on the structure.
This monitoring is necessary because steam equipment depends on constant pressure control to operate within safe limits.
Before departure, Joel fills the system with water through a specific inlet.
Then, the furnace receives pieces of dry wood, which serve as a heat source to keep the boiler active during the demonstration.
The autonomy mentioned in the project is related to the possibility of operating with wood and water, without relying on liquid fuels.
However, there is no reliable public information about the maximum distance covered, official average speed, or wood consumption per kilometer.
This point differentiates the invention of a commercial vehicle from a prototype tested in a laboratory.
What appears in the images is a functional handcrafted construction, operated by the creator himself and recorded in conditions compatible with the rural environment in which it was presented.
Rear boiler concentrates heat and draws attention in the video
During the demonstration, Joel uses the heat produced by the furnace to prepare food while the system gains pressure.
The scene shows sausages placed on improvised skewers near the heated structure before the tricycle starts operating.
The episode helps to show the physical layout of the project.
As the heat source is concentrated at the rear and partially exposed, it serves both to power the steam system and to heat nearby objects during the demonstration.
The situation does not allow us to conclude that the vehicle was designed with a regular culinary function.
What can be stated, based on the video, is that the creator took advantage of the furnace heat in a scene recorded as part of the tricycle presentation.
The rear structure appears to have been built with repurposed metal components, including a drum, pipes, fittings, and parts adapted for steam conduction and motion transmission.
Since there is no official technical sheet available, the identification of each material should be treated as a visual observation, not as a specification confirmed by the manufacturer.
Repurposed parts form the structure of the handcrafted tricycle
The tricycle brings together components from different origins, organized into a functional structure.
The front part resembles a motorcycle, with fork, front wheel, and extended handlebars, while the rear concentrates the thermal and mechanical system.
The seat appears to be repurposed from another vehicle, and the set of rear wheels works in conjunction with chains, gears, and axles.
Manual lubrication of moving parts appears in the demonstration, indicating direct maintenance during operation.
This assembly exposes the handcrafted nature of the project.
Instead of closed fairing, standardized panels, or conventional engine, the tricycle keeps visible the parts responsible for heating, pressurizing, and transmitting movement.
The absence of industrial finishing does not prevent the functioning presented in the video, but it limits any conclusion about durability, safety in prolonged use, or operational capability on different terrains.
For this type of evaluation, documented technical tests would be necessary.
Steam tricycle does not work as a gasogene vehicle
The association between firewood and transportation usually refers to vehicles powered by gasogene, used in Brazil during World War II due to the difficulty of accessing liquid fuels.
Despite this historical connection, Joel’s tricycle uses another operating principle.
In the gasogene, wood or coal undergo incomplete combustion to generate a combustible gas, which feeds adapted internal combustion engines.
In the tricycle shown in the video, the firewood heats water and generates steam, which drives the mechanical system.
An article from the Journal of the Institute of Brazilian Studies, USP, records that the gasogene was an alternative adopted in Brazil during the supply crisis caused by the war.
The technology allowed for the partial replacement of gasoline and other imported fuels in adapted vehicles.
In the case of the handmade tricycle, the connection with this historical technology is in the use of wood as an energy source, not in the type of engine.
Therefore, the most accurate description for the project is steam-powered tricycle fueled with firewood.
This distinction is important to avoid incorrect interpretation.
Joel’s vehicle is not presented as a gasogene car nor as an adaptation of a gasoline engine, but as a unique assembly based on steam generation.
Invention with scrap goes viral due to unconventional mechanics
The video circulated on pages and reports for showing a visually unusual solution: a handmade tricycle that moves using steam generated by firewood.
The combination of scrap, rural road, and operation without liquid fuel is the central element of the repercussion.
The project’s narrative also relies on the figure of the inventor who builds his own machine with available resources.
In this type of content, public interest is usually linked to the adaptation of materials, practical demonstration, and contrast with conventional vehicles.
There are no reliable elements to claim that the invention represents a viable alternative to regular transportation.
There are also no published technical data that allow comparison of efficiency, emissions, operational cost, or safety with other propulsion models.
Even so, the demonstration documents a handcrafted application of known mechanical principles.
The assembly uses heat, pressure, water, transmission, and manual control to transform firewood into movement, within the conditions presented by the creator himself.
Joel’s tricycle fits into a Brazilian tradition of improvised projects in workshops, farms, and small manufacturing spaces.
These are initiatives that do not replace industrial processes or technical standards, but record practical ways to solve problems with available parts.
The story also shows how ancient technologies continue to be reinterpreted in local contexts.
Instead of a locomotive or a stationary machine, steam appears on three wheels, in a vehicle assembled to circulate in a rural setting and demonstrate a mechanical idea outside the commercial standard.
Without official data on autonomy, speed, and safety, the real scope of the project remains limited to what has been publicly demonstrated.
