Both of these cars were competing in the same class, but the difference is the solar array. All of the Nuna cars have had multijuction arrays made of III-V semiconductor cells. Such cells are very expensive, and are only used in satellite or concentrator applications, but they can have efficiencies up to 35%. Enough cells to cover a solar car can easily be more that a million US dollars. Sunswift IV, on the other hand, has an array composed of Sunpower C-60 solar cells, which have a theoretical efficiency of 22%. The record they set was for a solar car with silicon solar cells, and as someone mentioned, they did the run without a battery pack. The wikipedia quote for theoretical top speed is running solely off battery, which doesn't make it much of a SOLAR car.
Yeah, so I have this little theory that Apple computers and other crap that they make are for stupid people. An in my experience, Linux is cool but I'm just not used to it and I like the applications that I am used to. So therefore, Windows is most productive for me, although if I were stupid my answer would be macosx.
Hey, I have an idea. You could get the ti-89, which can do symbolic integrals. It also happens to be much faster. I have enjoyed using it on many a test where the teachers didn't know its full abilities.

Great idea, memorize two three digit numbers that can give you 6 places of pi. Now all you need is a calculator to divide them ;)
