The world's most efficient hydrogen engine weighs just 16 kilos, produces 160 horsepower and can take 25,000 revolutions.
A team of American engineers has developed what they believe is the world's most efficient hydrogen engine. It weighs just 16 kilos, produces 160 horsepower and can take 25,000 revolutions.
And then it utilizes 60 percent of the energy that is supplied. Today, even the most advanced internal combustion engines can barely utilize 42 percent of the energy on a good day.
However, it has succeeded in developing some diesel engines for street cars, which can utilize half the energy in the fuel. The rest becomes excess heat.
But according to Interesting Engineering, the new hydrogen engine must replace both the one and the other crude oil-based fuel.

The engine is called the H2 Starfire and is a further development of the Omega 1 engine, which the same team of engineers is behind. In the new version of the engine, the team has reportedly succeeded in reducing the number of parts from 114 to 82.
But what really makes a difference to the engine's efficiency is its design, which can best be compared to a figure 8. It all works without the use of stamps.
At idle, the engine spins at 1,000 revolutions, but when all the muscles are needed, revolutions are right up to 25,000. The American engineers themselves believe that the engine can work in everything from cars to planes and ships in the future.
More horsepower shouldn't be a problem either, due to the module-like structure of the engine construction. All in all, the quest for fuel efficiency is perhaps more relevant than ever at the moment. Right now, for example, Toyota is testing an engine that burns ammonia. Read more about it here .
