OPEN SOURCE ELECTRIC VEHICLE PROGRAM
"OSEV"
Updated 12/17/08
GOAL
----
Maximize the displacement of petroleum powered miles driven with electric vehicle miles driven, powered by renewable energy.
WHY?
----
- Energy Independence
- Emissions Reduction
HOW?
----
Convert late model used petroleum powered compact vehicles to electric by:
- Developing a common design for EV conversions, using cost-effective state-of-the-art components in a safe manner.
- Drawing on the expertise of the EV community, and giving back to the community by collaborating with other similar organizations and publishing results in an open source fashion.
- Building prototype conversions and fully documenting them in textbook and video forms.
- Training people how to convert and maintain these vehicles, using the prototype, textbook and video.
- Encouraging and certifying existing and new shops to perform the conversions, and to then support them in the field.
- Sharing the prototype with public and private fleet managers and individuals.
Note: See NBEAA Advocacy page for convincing government to mandate and incent EVs and renewable energy, and for convincing large auto companies to make longer range, lower cost EVs.
