Shai Agassi's business model is to lease the battery, so the cost of the battery is distributed over the life of the vehicle. This also means you can drive for a few hours, swap out the battery for an equivalent one, and keep driving (45 seconds later)

This will require some skill on your part, but MATLAB can be an amazing teaching tool. A university Professor of mine used it to create animations and other visualizations.

Imagine being able to demonstrate trigonometric identities with animated sin waves, or geometry with 3d surfaces. As a programming language, it will give you incredible flexibility to demonstrate difficult concepts without putting emphasis on how pretty it looks.
