Some channels of research can take a long time to prove, disprove or found to be impossible or pointless. If time is the only issue this should not be considered an issue. Members have left the normal way of living to exist in a place of study and research, if they wish to spend 30 years of their life investing, time and effort into a theory it is their choice. However, should a commanding piece of evidence occur to completely negate their work or through its success make other other projects redundant the research / product is subject to review. Regular meetings and conferences should be organised meetings and conferences should be created where peers can discuss informally or to an audience the trials and results of their research all research and results are posted automatically online to the community and after the study is completed to the world for peer review.
All studies should be part of an open peer review service held within an extremely searchable format allowing people to quickly find relevant studies or similar experiments in the same area. These studies can subsequently linked to by on-line writers to show references the critiques of the paper, similar studies that have the same conclusion papers that have alternative or conflicting results.
The only significant barrier to continuing or starting research then is capital and the cost of obtaining the necessary equipment or tests (a CERN sized LHC is hard to find). In such cases it will depend of the size of the community, the R&D teams within the community and the importance of the research.
