Why is this Propeller Getting So Much Attention? Get an exclusive Surfshark deal! Enter promo code UNDECIDED for an extra 3 months free at https://surfshark.deals/undecided By changing the shape of a propeller design, we may have found a way to make drones (and a lot of other things that use propellers) not just quieter, but way more efficient. For some boating applications, the energy efficiency was boosted from 20% - 105%! Can this toroidal propeller really help everything from quieting tiny drones to helping boats sail further with less fossil fuels? And if just changing the propeller shape makes such a big impact, why haven’t we tried something like this sooner?
