There are three types of dissemination :
  1. Social
  2. Commercial
  3. Socio-commercial
Social Diffusion :
The innovations under social diffusion are those which may not have the potential of widespread commercialization but can enhance social wealth, improve people's lifestyles and facilitate sustainable alternatives for development. We call them open source technologies. Anybody can adopt them as per his /her need without any payment.
Parameters to be studied:

Understanding of the Innovation: Basic understanding of the innovation, which includes the technological need-gap that led to the innovation, benefits (tangible and intangible) and its econometrics.

Stakeholder analysis: identify stakeholders at micro and macro level drawing inter and intra sectoral linkage.
Fundability: the potential for the venture to receive financial support from funding agencies / investors.
Social Return on Investment: the venture's potential to meet its social goals and social impact.
Integration of the Venture's Social and Financial Missions: the alignment of the financial and social goals of the venture, nonprofit organization and funding agency.
Replicability in other geographical area: the holistic approach adopted in the projects for replicability in other geographical area.
Cost of diffusion: Many times the cost of diffusion is much higher than the cost of product itself.
Sustainability of diffusion: Closer farmer - scientists - extension worker interactions to keep communication alive; local adaptation or incorporation of local materials to make external technology easily replicable; etc. Innovations under Social Diffusion (Free Technologies) :
Commercial Diffusion:

In part execution of the mandate of National Innovation Foundation of generating wealth for the grassroots innovator and practitioners of tradition knowledge the Business development section facilitate incubation of green grassroots innovation and example of traditional knowledge, in the process generating wealth for the innovator, practitioners of tradition knowledge and supply change stakeholders. It covers five sets of activities mainly positioning of grassroots innovation and example of traditional knowledge across application domains, scouting entrepreneurs, selling business opportunities, providing hand holding support to new enterprise when it is most susceptible to various market risk and facilitation diffusion of socially relevant technologies.

Socio-Commercial Diffusion:
These are technologies which have high social impact but limited diffusion potential through commercial channels.
a) Low cost check dam
b) Low cost crematorium
There are some more technologies which have a mass potential and for which viable business model exist. eg. Low cost modification kit for treadle presses, which can help marginal owners of obsolete letter presses become competitive against press owners having conventional high cost computerised printing technologies
a. National & International Seminars to promote advocacy for the usage of these sustainable and low cost technologies and traditional knowledge
b. Increasing frequency and scale in affiliated programmes of the print and electronic media. Special emphasis for diffusion via ‘All India Radio’, which has got the widest coverage even in the remotest part of the country
c. Widespread decentralized demonstration of technologies and large scale on farm trials of promising agriculture related innovations
d. Road shows to showcase promising technologies and to get feedback of potential users/customers. These feedbacks can be used for identifying and improving features to find the best user fit for the technologies
e. Food and Herbal Festival to increase awareness. These festivals will be mainly conducted with network partner SRISTI, Ahmedabad
f. Diffusion through women Self Help Groups (SHGs) in active collaboration with Honey Bee network partners viz. SEVA, Madurai, PDS, Kerala, CCD, Tamil Nadu, Sristi Kendra, Orissa, Prithvi, Karnataka etc. and other diffusion clubs
g. Challenge Competitions so that people from all walks of life can offer various propositions for alleviating the disadvantages at the grassroots or vice versa
h. A subsidy scheme for percolation of technologies to marginal users, who could not otherwise afford the technology, but who can really benefit by usage of the technologies for economic gains
