MAKER FAIRE Gets GREEN! to modify Toyota Prius to "plug-in" hybrid at Maker Faire

"…when we eventually run out of oil, have a worldwide computer crash, or another global catastrophe, it's the sort of people who will subscribe to Make who will help us all survive."
- Knoxville News Sentinel

Sebastopol, CA (March 1, 2006)- Following President Bush's recent endorsement of advanced hybrids, and coinciding with Earth Day weekend, The California Cars Initiative ( will publicly convert a Toyota Prius hybrid into a "plug-in" hybrid during the inaugural Make magazine Maker Faire, April 22-23.

Over two days, CalCars engineers, along with a cadre of volunteers, will build and install a battery pack and make hardware and software adjustments to the stock Toyota Prius. The finished "PRIUS+" will drive back to Seattle, Washington after the Faire with a 10-mile low-speed all-electric range in addition to its regular hybrid extended range.

Unlike a standard hybrid, which uses the gasoline engine to power its battery, a plug-in hybrid adds a larger battery that can re-charge from a household 120-volt outlet. The result: a 100+ MPG plug-in hybrid fueled with gasoline plus cleaner, cheaper, domestic electricity.

Coming to the San Mateo Fairgrounds in San Mateo, CA, Maker Faire is a celebration of science and technology projects and the new Do-It-Yourself (DIY) mindset. "Make was created to expose the fun of technological hacking and discovery - and what could be more fun, not to mention worthwhile, than hacking a real world solution to our world's energy woes?" explained Make magazine publisher Dale Dougherty. founder Felix Kramer added, "If a handful of independent experimenters can create a plug-in hybrid over a weekend, imagine what auto-makers could do in a few months."

In addition to the CalCars project, other Maker Faire highlights include: 6 exposition & workshop pavilions (Weird Science, Ultimate Garage, Robotics, Digital Entertainment/Gaming, Green Tech & Electronics Recycling, Ultimate Workshop), 5-acre outdoor midway, over 100 exhibiting Makers, hands-on workshops, demonstrations, DIY competitions, crafting for Makers, Make: Movies, and the very latest in tools, kits and DIY resources.

The Details:
When: Saturday, April 22, 2006 (10am - 6pm), Sunday, April 23, 2006 (10am - 5pm) Where: The San Mateo Fairgrounds, 2495 South Delaware Street, San Mateo, CA
