For example, a pair of 1 watt 100 ohm resistors in parallel, in water, makes an excellent 100 watt dummy load for ham radio applications. If you run it for a long stretch you get steam, but the resistors stay healthy. For a 33 milliohm resistor, I might consider a suitable length of ordinary 20 gauge home electric wire, insulated, in water. That wire is rated for 20 amps in conduit, probably closer to 30 in open air, so 750 watts in water wouldn't be an unreasonable thing to do. paul
