Clean energy: Scrubbing wind turbines with robots nets Aerones $39M

Aerones, a robotics startup that scrubs and inspects wind turbines so humans don’t have to, secured $38.9 million in fresh funding this month from dozens of undisclosed investors, TechCrunch has learned.
Wind turbines produce clean energy, but their towers tend to leak oil, which can corrode blades, increase wind resistance and pollute the ground below. Aerones’ remote-operated robots clean towers and blades by blasting them with a liquid detergent, while funnels beneath the blades collect the mucked-up liquid for reuse. The robots also inspect turbine systems with cameras and ult
