This video provides an update on the build status of the Pipe Dream prototype. All components of the stator tracking system are now completed and mounted on the Pipe Dream apparatus. Several timing track test strips have been laid out on Masonite arcs which can be attached to the polycarbonate ring shown in the previous video. After a few final adjustments have been made, I will begin testing to determine which of the test track arc layouts works best. Sorry for the delay in creating this video. This phase of the construction process required a considerable amount of time to complete, and I have also been quite busy with other aspects of the Pipe Dream project. A Pipe Dream website is now up and running, and can be found here: rickspipedreamproject.uuuq.com A two part Pipe Dream builder’s document is available for download from the website, and features well over 100 pages of photos and step-by-step instructions for building the complete Pipe Dream apparatus as shown in these videos. A Pipe Dream Interactive Data Form has also been made available for downloading at the website, and this is to be used by all Project participants to report and share build specifications and test data. All data received will be made freely available to other replicators and experimenters. By freely and openly sharing information in this way, the Project can move forwards in the most efficient and cost effective manner possible. The Pipe Dream Project is a world-wide open source project …

i built my device with wood and brass-using much smaller neo’s to eliminate the large drage forces that you have demonstrated,which will also create drag against the copper coils i use for pickups.
im using reed switches to pulse drive coils-check my latest vid for an update

I saw your videos. Looks like you are into something entirely different with your pulse motor. No input power will be used here – strictly mechanical and magnetic means. By the way, what is a “drage force?” I don’t remember demonstrating any of those, whatever they are.

sorry was a typo-drag force of the magnet in the aluminium tube,its attributed to the eddy currents induced in the conductor.
my build was based on the work of Robert Adams and i followed his instructions of eliminating these eddy current losses by not using any steel or aluminium in the construction,and using a brass rod to mount the bearings.
the use of small neo’s applies to this engine,yours looks like a different beast altogether.
i share the same dream of PMMG,only mine looks different

Rick great vids.
Your series is now compulsive veiwing, each new edition egerly awaited.
Many thanks, and good luck.
Regards, Bren.

Yes, I am aware of the eddy currents. My stator magnet is shielded from the aluminum by its 1/4″ thick steel backing plate, and the rotor magnets are located more than 3.5 inches from the aluminum, so I don’t fear any problems. I am using a steel bike wheel as the rotor, which works like the permeability plate suggested in Howard Johnson’s PMM patent. Good luck to you with your pulse motor, regs.

Thanks for your interest, Bren. Glad you have enjoyed the videos.

If you would like to brainstorm, I hope you will join the Pipe Dream Project effort. Further information can be found at the Pipe Dream website. Please see the “info” area at upper right for details.

When is video 22 coming? The whole assembly running, and turning on its own, obviously after a push start.

Might be a few more days. I will be testing differing timing track layouts over a 90 degree section of the rotor to determine what will work best. That is the purpose of using the Masonite test arcs. After these tests are completed, I will lay out track on the entire 360 degrees of the polycarbonate track base, will spin the rotor up to 100rpm using an external force, and time the rundown to zero rpm. Rundown testing will be done with/without the stator carriage and with/without the flywheel
