I wondered about that too. The professor at Bristol has the following tweet - https://twitter.com/sonic_bruce/status/669560944234774528 https://twitter.com/soni

It says you need ~7.6kW of sound power to levitate a human.
That's sound power, so I'm not sure what electrical power you'd need too, I'm not sure how efficient the transducers are.
- mabbo 9y agoBe a very amusing way to trap a person. They can wave around all they want, but the tractor beam has them stuck, levitating. Maybe if they had a backpack and threw it sideways very hard?
- mschuster91 9y agoHmm. 7.6 kW for a human of something around 76 kg (makes calculating easier, reality should be 80-85). That means you'd need about 100W/kg... or, to lift a car of 1t, 100 kW. Should be do-able with a modern biturbo engine and by cutting some weight. Am I the only one thinking of a Star Wars repulsorlift?
