His first gas turbine patent was granted in 1884. In 1903 he completed the first turbine that produced excess power; his original machine used both rotary compressors and turbines to produce 11 bhp net. He further developed the concept, and by 1912 he had developed a gas turbine system with separate turbine unit and compressor
Gas compressor
A gas compressor is a mechanical device that increases the pressure of a gas by reducing its volume.Compressors are similar to pumps: both increase the pressure on a fluid and both can transport the fluid through a pipe. As gases are compressible, the compressor also reduces the volume of a gas...

One major challenge was to find materials that could withstand the high temperatures developed in the turbine to achieve high output powers. His 1903 turbine could withstand inlet temperatures up to 400° Celsius. Elling understood that if better materials could be found, the gas turbine would be an ideal power source for airplanes.

Elling also did significant development work in other areas, such as steam engine controls, pumps, compressors, vacuum drying et cetera.

In 1914 Elling produced a book called Billig opvarmning: veiledning i at behandle magasinovner økonomisk og letvint. (Cheap Heating: Guidance for the simple and economical treatment of base burners), which was published by Aschehoug
