While the Prius is more practical than high efficiency solar vehicles, why not add some solar to the Prius anyway? This solar kit from SEV seamlessly installs onto a Prius' roof and claims to add up to 32 kms per day of electric mode driving/increase fuel economy up to 29%. Compatible with Prius models from 2004-06, I'm enough of a cynic that I figure if the installation worked that well, the panels would have come standard in the first place (though we've heard that they are under consideration for next gen models). Then again, the 2-3 year "break even" scenario that SEV pitches on their website may have something to do with it. [SEV via Jalopnik]
