He later worked on the idea and created a blowtorch with strong, directed heat and with several safety measures.

[2] Nyberg worked on many other inventions including steam engines, aeroplanes and boat propellers.

From 1897 and onward until around 1910, outside his home in Lidingö he built and tested his Flugan on a circular wood track in his garden and on the ice during the wintertime.

He worked with the help of professor Johan Erik Cederblom (1834-1913) at KTH in the development of wing profiles but did not succeed to get Flugan in the air.

He also designed and built his own wind tunnel in order to test of small wing models.
