During technology transfer, a regular line of communication between all the active sites was essential to avoid duplication of effort, and to expedite adoption. The contact at the "push" site can nurture parallel collaboration between "pull" sites. As an example, the aging chamber's enclosure at Haverford was replicated from observations of the Stanford group's design. The improved enclosure increased the rate of preheating and decreased heat loss from sample loading. These types of improvements would have been more commonplace had there been an organized community of adopters who would expand the library of use cases for open hardware and act as another source of information . Such a community is common-place in developer and maker culture and would reduce the burden of the push sites to support multiple adopting labs , .
