Norwegian University of Science and Technology NTNU
[before 1996: Norwegian Institute of Technology NTH, University of Trondheim]
Born 1931 at Skudenes, Norway.
Graduated from NTH, Electric Engineering Department as "siv.ing.", 1957 and as "dr.techn.", 1972.
Active in research on ocean-wave energy since 1973, when Kjell Budal (1933-1989) initiated this research at NTH. Previous research interests were electromagnetism, physical electronics, thermonuclear fusion and plasma physics
