Invented by an entrepreneur from Finistère, the Eco Leau kit has found new customers. Its inventor promises fuel savings of up to 20% even if the subject divides.

In Huelgoat, Finistère, an entrepreneur has invented a hybrid water engine that adapts to all vehicles. This kit charged around 500 euros promises to reduce its fuel consumption by up to 20% even if the figure is debated. In the context of soaring fuel prices, Laurent Baltazar is overwhelmed with requests from all over France.

This is a principle that has already been tried out in the early days of the automobile industry before the First World War. One hundred and twenty years later, the water engine is making a resounding comeback under the hoods of our powerful cars. The main reason ? The staggering price of fuel, which does not seem to want to drop below two euros per liter, and forces the French to explore all solutions to reduce their consumption. It is in this context of inflation that the invention of Laurent Baltazar took on a new dimension. Based in Finistère, this jack-of-all-trades has developed an engine kit that is supposed to save fuel. Its promoter promises up to 20% savings even if this figure is widely debated.

In March, Laurent Baltazar was still alone in his company. Overwhelmed by demand, he had to urgently hire order pickers to deliver his precious kit. Called Eco Leau, the system is very simple and can be adapted to all engines. Connected close to the turbo, it injects moist air particles which are added to the fuel to improve the vehicle’s torque. Result: the motorist has less need to “press” to move forward and would consume less, according to its inventor. “Everything is purely mechanical and simple. An engine is like a human body, it needs air to function. But it works better if the air is humid”, explains Laurent Baltazar, who promises “up to 20% savings”.

When some are crying scam

Many Internet users cried scam after the publication of our article. To defend himself, Laurent Baltazar explains that his figures are based “on customer feedback”. They remain difficult to prove in the absence of serious study. The reality of the economy is so hard to verify that even the very serious School of Mines of Douai had stumbled on the subject. “Our study did not confirm that the water doping system was effective, but we cannot say that the Gillier-Pantone system has no influence on engine performance,” she explained afterwards. a long study on the system patented in 1998 from which Laurent Baltazar was inspired.

This idea, the entrepreneur had it by reading an article in Sciences et Vie in 2010 which evoked the recovery of exhaust gases. He focused on optimizing combustion and obtained surprising results. “We allow people to gain autonomy and above all, we are less polluting. Because we consume less, but also because we emit less fine particles, ”promises the former IT specialist. The system is especially effective on large engines and when the engine is hot.

For pollutants, it is more variable. The inventor takes the example of a Fiat Punto whose nitrogen dioxide (NOx) emissions had dropped by 30% after installing the kit. Garage mechanics confirm and even note another observation. By spraying water vapor into the circuit, the device limits clogging and in particular the problems of carbon deposits which clog the engines and cause nasty black smoke on old diesels.

To be assembled alone or in the garage

With all his arguments, the Breton entrepreneur naturally sees his order book explode with each oil shock. Since its invention in 2012, Laurent Baltazar has sold 20,000 kits. Boosted by the surge in black gold, the momentum has gone crazy and more than a thousand kits are sold each month. Growth such that the partner garages, however more and more numerous, are struggling to keep up with demand. Offered at 500 euros for a light car, the kit is charged just over 1,000 euros with the installation. “But you can also do it alone. You just have to know how to spot the turbo”, specifies Laurent Baltazar, who will soon open a showroom in Sainte-Sève, near Morlaix.

In recent weeks, the latter has seen a clientele assert itself. While working with 80% of individuals a few years ago, the Finistère has seen requests from professionals pour in. Because the kit does not only fit on all cars, it can also be installed on motorcycles, motorhomes, trucks or tractors. As for water consumption, it is minimal: around 20 centilitres per 1,000 kilometres. We are not done hearing about it.
