The more important mods include: solar panels on the roof and hood, a bigger battery setup (248 volt, 9 amp hour array) to give the solar energy somewhere to go when the car is parked, a retro analog instrument panel to keep track of all the added electronics, and a wood and glass/plastic cylinder thing on the top. No one was around when I stopped by, so I'm not sure what that's all about but, man, is it cool. In a "huh?" kind of way.
Bruninga writes that the solar panels and beefed up battery cost him about $3,000. He knows it won't get him 100 mpge, but he doesn't care. He wants to provide power for ham radio field days and explore the possibilities. One more thing: the passenger seat has been replaced with the DIY "Prius Inn," bed for one option. Who knew you could do so much to a Prius? He has plans for more, BTW.
