    no i literally agree they should use organic materials in windmills, its fucking maddening how our 'get off fossil fuel' devices are made out of petroleum plastics

    don't need them to be whole ass buildings if you're not milling anything though lol

      Using a light durable material to create blades with a low incident of inertia in order to generate cheap renewable electricity is one of the few instances behind which I can support mass application of plastics.

          There are new designs that can be recycled:

          And old blades can be reused to make pedestrian bridges, etc:

          But neither is happening at a large scale

        Whats the viability of bio plastics in this regard? Like im not talking economic feasibility but like from an engineering standpoint

          If I had to take a wild guess, I'd say they're brittler or heavier or both.

      And if you want you wind mills to generate more then a few watts of energy?

      Early wind turbines were made of aluminum, similar to aircraft wings of the time, so in theory they were longer-lasting and more recyclable. But they switched to composite materials because they're lighter and stronger, same reason airplane wings are switching to composites.
