I saw the Dirty Jobs tv show and they showed a team of 6 guys inside one of those 60 foot wind mills mopping up the oil that was leaking. They said it was routine maintenance. Doesn’t sound very eco friendly to me.
I’m thinking a really hot day will vaporize of the puddled oil, allowing any sort of spark from the electrical equipment to ignite the oil. After that, you have a nice hollow composite blade to act as a chimney.
60foot? Hell, some blades are that long.
