A Curious And Bold Test Used Unconventional Fuels In The Tank Of A Flex Car: Kitchen Alcohol And Even Cachaça. The Idea Was To Discover If, In An Emergency Situation, These Substances Could Make The Engine Work. The Results Were Surprising.

An experiment conducted by the channel “Cars With Tiago” tested a question many have had: can a flex car run on cachaça or kitchen alcohol? The answer was provided in practice — with surprising results.

Test Preparation

The test began with the careful preparation of the car’s fuel system.

The entire fuel line was emptied, and the engine was started with regular automotive alcohol to ensure it was operational.

First Test: Kitchen Alcohol

The first alternative fuel tested was kitchen alcohol.

Two liters of the liquid were placed in a makeshift small reservoir. The fuel pump was activated, and then the engine was started.

To the surprise of many, the car ran normally. The engine responded well, and it was even possible to accelerate. According to Tiago, “it runs“, although he warned that the continuous use of this type of fuel may damage the vehicle.

Still, in an extreme situation, it seems to be a viable alternative — albeit temporary.

Second Test: Cachaça

In the second part of the test, it was time for cachaça. The fuel line was emptied again, and 2 liters of the drink were placed in the same reservoir.

The pump was activated, and the car was started.

Once again, the engine started. However, the operation was quite different. The car had stalls, hesitations, and low response to the accelerator. “It’s not running very well,” said the presenter.

Still, the experiment confirmed: with cachaça, the car also starts.

Test Results

Although the tests were successful, the channel warned of mechanical risks.

The use of kitchen alcohol or cachaça IS NOT RECOMMENDED, but in an extreme emergency, it may work — although with limited performance and possible consequences for the engine.

Test Results

While an average building in London or New York takes three years to be completed, in China a 26-story tower went up in five days with about 100 workers, and the global modular construction market already moves US$ 95 billion per year.

A Chinese factory in Guangdong is assembling a humanoid robot every 30 minutes while Tesla, Figure, and Boston Dynamics still struggle to deliver 10 thousand per year.

Australia installs giant concrete structures on the seabed 800 meters from the shore to create an ocean intake for desalination that will draw in saltwater and produce 30 million liters of drinking water per day.

Secret chamber sealed 4,500 years ago found in the Pyramid of Khufu, and Hawass announces its opening to the world in 2026

A public school student single-handedly created a machine capable of treating water for up to 50 people using only solar energy. It was awarded third place at one of the most important science fairs in the world.

Germany installed vertical solar panels on a lake in Bavaria, and the result broke conventional logic: instead of producing energy at midday peak, the plant generates more early in the morning and in the evening, exactly when families turn on appliances and factories are in full swing.

While communities suffer from water scarcity and the advancing desert, women in Morocco use nets high up in the mountains to trap fog droplets, fill reservoirs, and transport drinking water through more than 10 km of piping.

Between Alaska and Siberia, there is an abyss on the sea floor, a submarine trench 2,600 meters deep that surpasses the Grand Canyon in vertical scale and hosts one of the rarest ecosystems on the planet.

It seems like something out of a movie, but it’s real: how technology uses invisible sound waves to extinguish small fires without water, without chemicals, and without destroying household furniture.

Chinese boats accelerate the collapse of fishing in Senegal, cause an annual loss of US$ 300 million, affect 1.3 million people, and help transform West Africa into the epicenter of 40% of the planet’s illegal trawling.

Super airplane Phantom 3500 advances towards its first flight, promising 60% lower fuel consumption, a windowless cabin, operation above 51,000 feet, technology validated by DARPA, and a billion-dollar order of 300 jets before certification.
