An interesting new technology for flight:
Or as FanWing Ltd. calls it: “a revolution in flight technology” :)
Reminds me of another (even more revolutionary) interesting new flight technology, The Lifter Project. According to expectations, the efficiencies of these technologies are quite different. Whereas the FanWing
achieves an efficiency in the order of 20 g of lift per watt of input power, the best Lifters seem to achieve a lift efficiency of about 0.64 g/w (DC, not pulsed) and 2.55 g/w in theory (pulsed DC)
