I will start the Gravitational Propulsion Research History as it relates to me ; (James Stevenson). Since most visitors here will be seeking information relating to my research theories and the research groups that I worked with. I will admit to be active in related theory and therefore will not disclose all information at my disposal, however I will release related data for scientific review and historical review as well.Lets get to it.

Around 1980 I discovered a rather large geometrical model that seemed to include a multitude of interactions of various factors in Physics. I began building some simple and not so simple devices to test the indications of certain theoretical concepts. One of the devices was a simple "gravitational interactive sphere", which I displayed in a number of universities and was interviewed by numerous newspapers, magazines, and some TV news pieces. I hoped eventually to create a foundation upon which to build successive phases of "Gravitational Propulsion" R&D.

Eventually I sent a proposal to the NSF and had somewhat favorable reviews, but I wanted to go on to a more elaborate propulsion system and so in the mid 80's I released a short "Gravitational Propulsion Theory and Research Proposal". I have placed a ZIP of that early theory in my files and here is a link to it; Gravitational Propulsion Theory and Research Proposal.zip

There were some supplemental documents that supported the general concepts of that theory and proposal, and were included as an attachment to the proposal and they are here in the files as well as a ZIP at; Supplemental Documents to GP Theory by Stevenson.zip
