Tesla mentions the possibility that is described in your reference in "the problem of increasing human energy", more or less quoting from Newton. I have tried to make such a model work, but I believe now that it is impossible. Too much energy needs to get absorbed in masses to generate a force as we know it, it would quickly evaporate all matter. But I'll check the electric universe... there are clever people over there.
If you have any other suggestions of where to look... May save some time... :)
The model that I described here seems to work, but I'll need to dig a bit deeper.
This may fill the last blank spots that I see in Tesla's theory, and hopefully supply us with something we can actually verify in an experiment.
Exciting times ahead!
