Ultrasonic Standing Wave Suspension could the transducer support itself?

    Ultrasonic Standing Wave Suspension could the transducer support itself?

    Essentially looking at items that state a surface area of 1m2 could support 11.5kn at 16 Watts (Hemsel, 2013) could the transducer suspend itself from the reflector using the same theory even though the suspension point is at the second wave from the transducer if it were within the parameters of weight to surface area?

    I fear you overlooked something.
    They state clearly : "The first system was able to lift a weight of 3 kg using an electrical input power of only 16 W. Based on the surface area, a lift capacity of 11.5 kN/m2 was reached."
    11500/30 ~ 380; 16W* 380 ~ 6000W, so even assuming peripheral losses will diminish when you scale up, 5kW seems to be a more reasonable estimate of the power required to lift 1.15 (metric) tons, given the technology used.
