Biografi
Professor Bernhoff erhöll sin doktorsexamen från Kungliga Tekniska Högskolan (KTH), Sverige, 1992 inom området materialfysik/ytfysik. Efter ett år (1992-1993) som postdoktoral forskare vid IBM Research Division i Zürich, Schweiz, började han på ABB Corporate Research i Västerås (Sverige) som projektledare. År 2001 blev han docent vid Institutionen för elektricitet, Uppsala universitet, och utnämndes till professor 2011.
Han är en seriell entreprenör (medgrundare och första VD) för Energy Potential AB, Seabased AB, Vertical Wind AB och Electric Line Uppland AB. Han har varit styrelseledamot i det svenska vakuumvetenskapliga sällskapet (1996-1998) och FRAM-konsortiet (Fundamental Research and Application of Magnetism) från 2002. Professor Bernhoff har fått ett antal utmärkelser: Årets Uppfinnare från ABB Corporate Research (1994 och 1995), Sveriges Ingenjörers Miljöfondens Stipendium (2004 och 2011). Han är uppfinnare eller med-uppfinnare av 30 patent inom våg-, vind- och puls-kraft och energilagring.
Forskning
Vid Uppsala universitet har Bernhoff främst varit engagerad i forskning om vågkraft med en direktdriven punkt-absorberande teknik, puls-kraft med induktiv pulsgenerator (40 TW demonstrerades framgångsrikt) och vindkraft.
Inom vindkraft har Bernhoff främst studerat vertikal axelade vindturbiner, där bladen roterar runt en vertikal axel i motsats till en horisontell, som i konventionella vindkraftverk. En av fördelarna med en vertikal axel är att generatorn kan placeras på marken, vilket ger bättre prestanda och billigare byggkostnader. Han har studerat och utvecklat ett helt nytt direktdriven vertikalt axelvindturbinsystem för stora applikationer och i samband med spin-off-företaget Vertical Wind demonstrerat nätansluten drift i den 200 kW Falkenberg VAWT. För vilka två föregångarsystem utvecklades och studerades: en 2 kW vertikal axelvindturbin från Uppsala universitet konstruerades 2005, och 2006 utvecklades och byggdes en 12 kW turbin i Marsta utanför Uppsala. I Falkenberg demonstrerade han även världens första moderna trätorn för vindkraft. Han har också utvecklat och installerat småskaliga Savonius-baserade vertikala axelvindturbiner för stöd av neutrinovetenskaplig forskning på både Antarktis och Grönland.
De senaste åren har han varit involverad i att utveckla ny teknik, CRAFT - Counter Rotating Axis Floating Tilted turbine, för offshore flytande vindkraft.
