Discover the incredible technologies that use salt water, waste and wind to replace gasoline and revolutionize mobility in a sustainable and innovative way!
In recent years, different technologies have emerged with the aim of replacing gasoline as a source of energy for vehicles. Some proposals stand out for their creativity in using unconventional resources, such as salt water, garbage and even wind, in an attempt to make transportation more sustainable and accessible. Although still not in large-scale production, these alternatives are arousing the interest of engineers, researchers and those curious about solutions that eliminate dependence on fossil fuels. Keep reading and find out everything about the car powered by salt water, garbage and even wind.
Cars powered by water and garbage: Argentine engineer's project gains international attention
Argentine engineer Edmundo R. shared an initiative that uses two unusual elements as a source of energy: water and garbage. The proposal involves a system that generates gas through the decomposition of organic waste, such as food scraps, mixed with water. This gas replaces gasoline and powers generator engines, pumps and even vehicles without the need for major modifications to the original system.
The low-cost car powered by water and waste has attracted attention due to its autonomy. According to its creator, a vehicle equipped with the system can travel up to 1.000 km on a single charge of supplies. The system manual was made available free of charge to anyone interested, with the aim of encouraging the application of the idea in regions with little access to traditional fuels.

The engine powered by water and waste has been tested in countries in Latin America and Europe, expanding the discussion on alternative energy in the engine and waste reuse solutions.
Energy from the sea: car powered by salt water is a reality in Germany
In Germany, a electric car that runs on salt water as fuel has traveled more than 150 km in tests. The model, developed by the company NanoFlowcell, uses a flow cell technology that transforms liquids with electrical charges (positive and negative) into electrical energy. The vehicle, called Quantino, runs without emitting polluting gases and uses tanks with two different types of salt water-based electrolytes.
The system dispenses the use of traditional batteries and supplies the electric motor with the energy generated during the chemical reaction between liquids. The water-powered car has become an example of how elements abundant in nature can be reused to power vehicles. The proposal fits into the technologies that seek to eliminate the use of gasoline without sacrificing autonomy and performance.
Wind-powered car attempts to break land speed record
Another invention that breaks with traditional standards is the wind-powered car, developed by Emirates Team New Zealand. The vehicle was designed to reach speeds of over 200 km/h using only the power of the wind. It has three wheels, a carbon fiber structure and a rigid sail measuring approximately eight meters, similar to those used on racing sailing boats.
The team's goal is to break the world wind-powered land speed record, set in 2009. The tests are scheduled to take place in flat, desert areas of Australia, where conditions are favorable for taking advantage of the constant winds. The innovation reinforces the quest for gasoline-free cars, using natural resources as the primary source of propulsion.
Advances and limitations of new technologies
Despite the innovative proposals, the technologies presented still face limitations. The current supply infrastructure, production costs, engine adaptation and the need for regulation make immediate large-scale adoption difficult. However, tests and projects already in operation demonstrate that the automotive sector is open to new paths, with a focus on alternative energy sources in the engine and solutions that replace conventional fuels.
The range of approaches — from using waste and water to using wind power — shows that there is room for different solutions to coexist. While some of these initiatives are still experimental, others are moving closer to commercially viable and sustainable models.
Gas-free cars: a closer future?
With advances in research and technology, interest in vehicles that use clean and renewable sources is growing. The search for gasoline-free cars is a reflection of the global demand for less polluting and more economical alternatives. The use of salt water, organic waste and wind expands the possibilities and reinforces the idea that different paths can lead to the same goal: the replacement of fossil fuels in transportation.
The inventions highlighted demonstrate how simple ideas can be transformed into functional projects. Although they are still far from mass production, these initiatives point to a future with more sustainable mobility options. The water-powered engine, the wind-powered car and the system that turns waste into energy are examples of how creativity combined with engineering can open up new possibilities in the automotive sector.
