A surprising innovation in the transport sector: a motorcycle that runs exclusively on water, ‘promises’ to be able to travel more than 1.000 km on a single tank.

The promise of this innovative motorcycle reveals a technology capable of extracting hydrogen from water to use it as fuel, revolutionizing the concept of sustainable mobility.

According to reports, the highly efficient electrolysis equipment installed on this bike is the core of this innovation. It was supposed to extract the hydrogen contained in the water, which is then used as fuel. This approach eliminates the need to store hydrogen in high-pressure tanks, as only the necessary hydrogen is extracted. Furthermore, the motorcycle's security system deactivates the hydrogen generation in case of accidents, avoiding the risk of explosions.

Consultation with engineers and experts

The idea of ​​a water-powered motorcycle, which would supposedly function as a self-sustaining source of energy, is often approached in the context of mobility innovations. However, it is important to analyze this idea in light of the laws of physics and engineering.

Firstly, it is essential to understand that every machine, to function, needs an external source of energy. This energy is converted by the engine into useful work, but there are always losses in the process, mainly due to factors such as friction and heat. For example, in a combustion engine traditional internal engine, only around 25% of the energy from gasoline is actually used to move the vehicle; the rest is lost mainly as heat.

In the case of a motorcycle that would supposedly run on water, the general idea would be that water could be broken down into hydrogen and oxygen through electrolysis, and the hydrogen would then be used as fuel. However, electrolysis requires electrical energy, and this energy must come from some external source. It's not possible, according to the laws of thermodynamics, that the motorcycle generates more energy than the energy it initially received to start electrolysis.

Therefore, the idea of ​​a water-powered motorcycle that would produce enough hydrogen to propel itself and still generate surplus energy is scientifically unfeasible. Such a concept would violate the first and second laws of thermodynamics, particularly the principle that it is not possible to create or destroy energy, only to transform it, and that no system can be 100% efficient due to inherent losses, such as friction and dissipation. of heat.

Therefore, a motorcycle that runs exclusively on water and is capable of producing its own energy in a continuous and self-sustainable way, without the need for external fuel, is not viable with the current understanding of the laws of physics and engineering. Engines that use hydrogen as fuel are an area of ​​research, but the hydrogen used in these cases still needs to be produced and stored in a traditional way, using energy from external sources.
