It's a bit of a hybrid. One of the students wrote a Message Transport Agent that allows computers to pick-up tasks from another computer if it becomes too busy or fails. Generally, tasks run on one computer.

I'm not sure.

There is a separate 6KW generator that sits where the front passenger seat used to be.

Yes, we have four emergency stop buttons around the vehicle. Testing has been... Um... interesting. Today, one of the team members sent a bad command to the throttle controller and the vehicle took off at full throttle without any warning. It must've hit 40-50 MPH before someone hit the remote kill switch
. Last weekend the Tahoe took off at full throttle and pointed itself in the general direction of the film crew that's been following us around. With any luck, we'll get to see it on PBS' Nova in late Spring
