Windy critics

turbine developmen­ts. The most notable was the New Zealandbas­ed Vortec that collapsed in 2001 after chewing through $25m in funding. The NZSX-listed Windfarms New Zealand is not involved in turbine developmen­t and uses industry standard propeller generators at its 97-turbine farm in the Tararuas.

Manwell was troubled by Ogin’s lack of public progress since 2008, despite several fundraisin­g rounds totalling more than US$100m.

Hefound the informatio­n vacuum unusual.

California-based wind energy analyst Paul Gipe, said the collapse of Vortec raised the stakes. ‘‘The burden of proof becomes great because of all these failures.’’ He said the investment is a gamble. ‘‘That’s what venture capitalist­s do, they try to make a big bet. Your pension fund is betting, and this is a wild bet.’’

The criticisms are echoed by local wind consultant and PhD candidate Dougal McQueen.

‘‘Wind turbines are a mature technology and the designs have not changed substantia­lly in 30 years,’’ he said. Prior failures showed the ducted model was ‘‘fundamenta­lly flawed’’.

Ogin founder and aerospace scientist Michael Werle understood the scepticism, but said ‘‘we’ve taken all the lessons learned and brought in some new aeronautic­al and aerospace concepts.’’ Problems with the Vortec developmen­t had been closely studied and remedied.

Ogin chief financial officer Jantoon Reigersman said Ogin was finalising its commercial design and hoped to put more informatio­n into the public domain next year after gaining engineerin­g certificat­ions and commencing mass production.

Matt Whineray, NZSF general manager, said the US$55m investment – a mixture of debt and equity seeing the fund take a less than 20 per cent share alongside the likes of Goldman Sachs and the Alberta – followed nine months of due diligence. The fund was well-aware of risks of early stage companies, but believed this one worthwhile.

‘‘This is a small investment in the context of a $25 billion highly diversifie­d fund,’’ he said.

‘‘We expect to be compensate­d for the risks we are undertakin­g.’’
