Cleantech Transit Inc. (CLNO).

Cleantech Transit Inc. was founded to capitalize on technology advances and manufacturing opportunities in the growing clean energy public transportation sector.
Biomass energy comes from organic waste materials such as yard clippings, wood chips, sawdust, branches, manure and miscellaneous paper materials as well. There are quite a few more types of organic material that could be used as a potential biomass fuel source.

The appeal of biomass fuel is that it is a renewable source of energy and greatly reduces the level of pollution output as well as landfills. Biomass fuels could be used in rural or indigent areas with ease because of their renewable properties. This source of energy could be used to produce heat, steam, and electricity or even for transportation purposes.

Cleantech Transit Inc. is pleased to provide further details on finalizing the 500 KW project. Cleantech expects to finalize its initial interest in the project around July 15th and is in talks to further increase its interest in the 500 KW project in Merced County. In addition, the Company hopes to negotiate definitive terms for the previously announced larger projects. In particular Cleantech is interested in the larger 1 MW biomass gasification facilities and will provide additional details as the Company has confirmed terms on the larger projects.
