Windmill pushers, that is.
Wind turbines may catch on fire ten times more often than is publicly reported, putting nearby properties at risk and casting doubt on their green credentials, researchers have warned.
It points out that the wind industry body, Renewable UK, has admitted there were 1,500 wind farm accidents and incidents in the UK alone between 2006 and 2010 - while just 142 individual accidents in the UK were documented in CWIF’s database over the same period.
This implies that less than 10pc of incidents are publicly reported.
Dr Guillermo Rein, of the Department of Mechanical Engineering at Imperial, said: “Fires are a problem for the industry, impacting on energy production, economic output and emitting toxic fumes. This could cast a shadow over the industry's green credentials. Worryingly our report shows that fire may be a bigger problem than what is currently reported.”
