Steam loop

[wazioc]

So, perhaps an off the wall idea, but figured this was the place for it.  I've recently become interested in the idea of overunity and started looking at different devices.  Found this one:

But I cant find much information on it so I really dont have anything to back my ideas, but maybe someone else knows something. 

According to the video, its been measured up to 70% more energy out than in.  If this is the case, could it be possible to make a loop?  electric motor powering steam generation in turn using the steam to generate electricity to be put back to the motor and using the excess to store in batteries or drive another motor?   Anyone have any more information on this device or any steam powered electric generators?

Steam engines are way to innefficient to make a selfrunner, but I've been wondering if stirling engines would be up for it.

I think that device has been discussed here before, probably several times, but I haven't seen anyone test if it actually is overunity or not. I think that would be wise to check first. Since that video they've got their company up and running, but have taken back their claims of overunity, and are just marketing them as really efficient heaters. Whether that's just a low profile marketing strategy can be debated of course.
