Hot water/steam = free $/energy

Not really. The energy required to create steam from water is 970 btu/lb (1 ib of 212 degf water to 1 lb of 212 degf steam). It releases backwards the same way, so no energy gained.

Think "creating heat" vs "moving heat"

Chillers move a whole lot more heat than they create from mechanical energy driven by electricity. Read Richard's explanation a couple months ago on "heat pumps". This is why "heat movers" provide efficiencies greater than 100%.

Now the question of the microwave heater is does it create heat from electricity or move it? Compressors used in airconditioning and heat pumps have shafts that rotate and compress gas. PV = nRT, which means with nR and V constant, when pressure goes up, temperature goes up...mechancial energy produces heat we don't actually want.

Now as to the video, note that those rotors are turned by electrical motors, creating centrifugal force, raising pressure and therefore temperature so that water going in is heated (to steam in some cases). It's known as the heat of compression. Also the friction of the shaft on the bearings is transferred to oil, which is transferred to the water as well.
