I'm a technology designer and digital effects artist living in southern Oregon. I have held some interesting jobs throughout the years, including library technology trainer, starting a solar-powered coffee roastery, inventing 3D display technology, manufacturing 3D printers, and creating animated sequences for music videos. 

Idea Propulsion Systems is a venue for my growing collection of interesting thoughts and ideas. Some of the postings are quick factoids, and some are master plans designed to change the world. Most are somewhere in between. Please contact me if you wish to re-post or otherwise share material you see here. 

There is also a bookstore where you can browse through some of the books I have written. If you like the book's description and associated free content, consider buying the book for your makerspace, classroom, or personal projects library. :-)
