The big problem with small wind turbines is that they don't have a big enough swept area which make them very inneficent. The solution to that is to have bigger blades which need bugger towers. If they have found a way to increase swept area without big blades then that could be a real game changer. It could just tip small turbines into viability. And you could see this concept popping up in lots of different places. And it could be complementary to other technologies like HVAC systems, louvres, ships etc. And maybe they could be placed on farmland during the winter.
