Engineering - August 2006

Our company is having all of its stores design and build a pinewood derby car (starting with the official BSA kit) and then racing them all at its annual manager's meeting. The only rule is, there are no rules. Got any suggestions?

You hear so much about nanotech nowadays. Universities are pumping lots of money into nano research. Is it just a fad or the wave of the future? Are there any good employment opportunities in this area?

I want to make a small heating element, using resistance wire and a battery. The point is that I need a small hot rectangular surface (only about 1cm x 2cm).
I was thinking of using a small copper plate (for its high thermal conductivity) and "zig zagging" some NiCr wire along one side of it (so that the other side will be the hot flat surface I need), but the problem is that that will short the circuit since the resistance wire is not insulated. I've been looking for coated resistance wire but I cannot seem to find anything like that.

I need the temperature to be fairly high so I doubt I can use tape to insulate the plate. Maybe I could use another material but I can't think of anything (a ceramic plate could handle the temperature but its thermal conductivity is bad and I wouldn't know where to get it)

so If you have any suggestions on this, just shout
