The fuel for the potentially groundbreaking rocket engine is to be based on biomethane, obtained largely from cow excrement.
A Japanese space start-up called Interstellar Technologies recently tested a prototype rocket engine powered by liquid biomethane, obtained mainly from cow feces – we read in “Rzeczpospolita”.
Interestingly, the information that the Japanese created groundbreaking rocket fuel from cow feces is not just a colorful curiosity, but may be a truly breakthrough invention in the field of ecology and space technology.
Big cow breakthrough
A series of “static fire tests” for the Zero launch vehicle took place at the Taiki spaceport complex in Hokkaido. The engine then tested generated a horizontal blue-orange flame that burned for approximately 10 seconds. And all this is based on biomethane obtained from cow excrement collected on local farms. The ecological “cow element” was the main source of this innovative rocket fuel.
Ecological cow supply chain
When developing their invention, the Japanese from Interstellar Technologies want to use a truly ecological, regional, closed-loop supply chain, which is to be a solution that benefits the natural environment.
A successful test of a rocket engine powered by liquid biomethane (LBM), derived from cow excrement, could be a major breakthrough and a major step towards a sustainable future in space exploration. This solution is expected to be implemented in 2025.
