This solution is used for
everything from concrete to pancake mixes to paint so I can see the desire to attempt it - we're talking about a lot of mass, here.
I'm not an engineer, but my feeling is that their proposed solutions are, even with very intelligent circuitry, just not going to do what they want them to do.
As for the water 'spoiling', lots of ways around that one. They could even have the machine fill and drain every time it's used...which would, of course, defeat the whole 'eco' aspect of the thing. If my suspicions are proved right, though, first seriously unbalanced load at spin and this machine will take care of the longevity problem by self-destructing, anyway.
