A Cambridge team test the limits of solar power as they prepare to race a car across the Australian outback fueled only by the sun's energy

Interesting.  I had wondered about solar tracking in a vehicle. 

The multi-junction cells actually are supposed to work better with concentrated sunlight.  I wonder if there would be benefits of adding Fresnel lenses to the array, which might also allow making a smaller, and thus cheaper array.

I like the idea of long-distance solar vehicles, but I do think the largest benefit will be local hops, driving the car to work in the morning, letting it sit in the sun all day, then driving back home in the evening.

Will there come a time when drivers will pay a premium for parking bays that remain unshaded all day long, eh!*

NB: not in the UK, I suspect.

I find that the top level of car parks are often emptier than lower levels.
Solar vehicles may reverse that trend.

Of course, the other option is to have fixed solar panels, and plug the vehicle in, and thus much less emphasis on carrying the panels around everywhere.  Then, in the car-parks, one can shade the vehicles with the solar arrays.  Not that we have an excess of renewable electricity, so one can always just feed the grid.

Anyway, I like the Cambridge concept of a smaller solar vehicle with solar tracking high efficiency cells.  Just don't toss a bag of groceries onto the $200K solar array.
