Update on the hovercraft: Took measurements of our gas-powered leaf blower and the eventual pilot, my 10-year old son. The pilot takes up about 22" x 22" in a cross-legged position. Then we weighed the pilot with and without the leaf blower, and calculated the weight of the blower. Next we need to do a layout to determine the size of the craft. And then we will calculate the static stresses we expect to see (not because we need to, but just for fun).
On a random note, I don't know if I will ever buy a 64-bit operating system again. I can't believe how many things won't work properly, and how much annoyance my laptop has caused me over the last year. I knew there were issues, but really thought they would be worked out over time.
Spatial IQ: Ability to mentally manipulate 3D objects. I think this may be my greatest engineering contribution to my family. In other words, I can pack a lot of stuff into small spaces, be they cars, boxes, or whatever.
I know I appreciate your Spatial IQ, given my spatial-challenge-ness.
