Solar Car Speed Record Smashed

An anonymous reader writes with word from Australia that "There's a new world record for the fastest solar-powered land vehicle: 88 km/h average speed over one kilometre in a lightweight car that uses about the same power as a toaster." As the article goes on to explain, this solar racer, built last year by students from the University of New South Wales, managed to nab that speed record earlier this month on an Australian navy base airstrip.

are photovoltaics required? it would be fun to enter a steam engine / mirror driven vehicle, something large like the size of a tractor trailer with huge mirror collectors. it wouldn't be very fast but unlike the photocell models it could have an air conditioner and heater core.
